Protection Functions
The module provides full protection for motor by supervising three phases voltage, three phases
current, earth fault current, startup time, the state of contactors and the state of main switch.
Responding of protection functions is based on the parameters given by user. The operation of
separate functions is independent thus protection functions can be active at the same time but

Thermal Overload protection
Thermal overload protection (TOL) protects the motor against overheating.
The motor thermal condition is simulated by a calculation. The result of the calculation is stored in a
thermal register and can be reported via operator panel or fieldbus interface.
Calculation is accomplished in a different motor operation conditions, principle presented below,
thermal increase and decrease are simulated by TOL protection function for running and stopped
motor.
Fig 22 Principle picture of motor thermal simulation
MC510 simulates thermal conditions in the motor for all operating modes (Running or Stopped).
This permits maximum utilization of an installation and assures safe protection of the motor.
Thermal overload protection simulation accounts for the temperature rise of both the stator
winding and the iron mass of the motor, it gives thorough consideration on the effect of motor
overheating due to three phase unbalance during the simulation calculation of motor thermal
overload.
FUNCTIONALITY
35
There are two thermal models supported by MC510: Standard or EEx e. The standard model
makes use of parameters Trip class, t6 in thermal overload calculation. The protection of
explosion proof three-phase motors with type of protection ‘increased safety’ EEx e is done with
two special parameters, the Ia/In ratio (stall/nominal current ratio) and Te time.
The following diagram offers the characteristic curve of overload protection, in which the
characteristics are adjusted by changing t6 (trip t
state).
If EEx e thermal overload protection is required, please contact ABB for detailed
clarification.

If motor is in overload condition, i.e. ILmax > 1.14 x TFLC (Thermal full load current multiplier
reduced by motor ambient temperature), the Overload alarm is active to indicate overload.
In some applications it is beneficial to be able to bypass the TOL protection momentarily because
of the process reasons. The lifetime of the motor will be shortened but it might be more costly to
stop the process.
MC510 provides the function of TOL bypass protection. If the TOL bypass is triggered:
That is, when the motor is running, the thermal capacity value is allowed to reach 200% before a
trip occur.
Or when the motor has been tripped due to thermal overload protection, the motor is required to
start urgently when the heat capacity is below 200%.
TOL bypass protection may cause overheating and even fire. This function can be used
only if the customer is clear about the load, even if the motor is required to operate
under overload conditions. Otherwise, it may cause equipment damage, serious injuries
or even death.
More detailed information on TOL protection parameter, please refer to Chapter Parameter
description.
Stall Protection
Stall protection is used to protect the driven mechanical system from jams and excessive
overload. Stall protection function uses Imax as the criterion.
Fig 24 Stall protection
More detailed information on stall protection parameter, please refer to Chapter Parameter
description.
Stall function activates after motor nominal startup time has elapsed.
FUNCTIONALITY
37
The highest measured phase current (ILmax) is compared against the Trip level. When ILmax remains
over the trip level at a time longer than Trip delay, a “Stall” alarm is issued and the contactor
tripped.
Long Start protection
The long start protection protects motor against locked or stalled rotor in starting state. MC510
detects the current after a start command, and signals a fault when current continuously exceeds
a separately set threshold of the period of start time.
This protection function is active only during the parameterized motor startup time. If motor startup
time has elapsed and will cause relay activation in case of a motor stall, but not long start protection.
Long start protection function is based on the highest measured phase current.
Fig 25 Long start protection
More detailed information on long start parameter, please refer to Chapter Parameter
description.
Long Start protection activates during motor nominal startup time and disables automatically
after predefined startup time.
The highest measured phase current (ILmax) is compared against the Locked rotor level. When ILmax
remains over the trip level at a time longer than Locked Rotor delay, a “Long Start” alarm is issued
and the contactor tripped.
Phase failure protection
MC510 protects the motor against phase current loss condition. Phase failure protection function
uses ILmin/ILmax (the ratio of lowest ILmin and highest measured phase value ILmax) as the criterion.
Function is suppressed by parameters Motor startup time, Number of phases and Softstart ramp time.

time longer the Trip delay, an “Unbalance Trip” alarm is issued and the contactor tripped.
Underload protection
MC510 protects the motor against underload condition. Underload protection function uses ILmax/In
(the ratio of highest measured phase value ILmax and the rated current of the motor In) as the criterion.
There are other parameters to be determined, such as alarm level, trip level and trip delay. The
protection characteristic is as follows:

Earth fault protection
There are two ways of earth fault protection in MC510 protects the motor against the earth fault
condition.
Direct measurement of zero sequence current through an external RCT
Calculation of zero sequence current by internal calculation through measurement current values
The function is by default suppressed by parameters “Motor startup time” and “Softstarter ramp up
time” to avoid nuisance tripping due to harmonics caused by saturation of the current transformers.
In some cases, it may be required to be switched on during startup in specific project requirements.
This protection is neither intended to be used for pre-emptive isolation supervision nor for
personnel protection against electrical shock. For these applications ABB recommends the
usage of external protection devices (PRCDs / RCDs).

Undervoltage protection
MC510 protects the motor against undervoltage condition as “voltage dip”. The undervoltage
protection function uses ULmin as the criterion. There are other parameters to be determined, such
as alarm level, trip level and trip delay, reset voltage level.

ULmax as the criterion. There are other parameters to be determined, such as alarm level, trip level
and trip delay, reset voltage level. The protection characteristic is as follows:

The power factor is compared against the trip level. When it remains below the Trip level at a time
longer than Trip delay, a “Under power trip” alarm is issued and the contactor tripped.
Phase sequence protection
MC510 protects the motor against wrong phase sequence condition. The protection bases on the
sequence of voltage input while motor is stopped. And while motor is started, it bases on the
sequence of current. The predefined phase sequence as following,
Voltage: VL1,VL2, VL3
Current: IL1, IL2, IL3
While the protection is enabled, there will be a trip while the measured phase sequence is different
from the predefined sequence.
The function is by default suppressed by parameters “Motor startup time” and “Softstarter ramp up
time” to avoid nuisance tripping due to harmonics caused by saturation of the current transformers.
In some cases, it may be required to be switched on during startup in specific project requirements.
FUNCTIONALITY
45
More detailed information on phase sequence protection parameter, please refer to Chapter
Parameter description.
Start limitation
Start limitation helps to protect the motor and also the process against excess number of starts in a
given interval. When the number of starts is reached and the motor is switched off, a new start is
prevented. The time interval starts from the first start. After the elapse of the time interval the
counter is reset to the pre-set value. The permissible motor starts per hour can be obtained from the
manufacturers motor and apparatus data sheet. However, the minimum waiting time between two
starts shall be complied.
The parameterization of the protection function can be the number of starts per time interval or the
time between two consecutive starts. In the first case the user must wait after the trip for the reset to
take place before making a start.
Independent of this function, the motor is protected by TOL function and a start is possible only if the
thermal capacity is below the startup inhibit level. If motor data specifies the number of starts during
a certain time span the advantage of this protection function can be taken of supervising the number
of starts. On some other cases process may put requirements for the motor start number thus this
protection can be employed.
Functionality is presented in the following example. Fig. 36 presents the start limitation protection
with 3 starts allowed.
1) Normal situation, after stop command motor can be started normally, “Start 2”. Every start
activates an internal timer for the time defined by time interval parameter. The number of active
timers are reviewed after every stop command and compared to value of number of starts parameter.
Stop command can thus exist during active or elapsed timer.
2) Two timers are still active, thus stop command generates alarm message "Start limitation alarm"
and one more start “Start 3” is allowed.
3) The 3rd start has been executed. A contactor trip and trip message "Start Limitation Trip" alarm will
follow when motor is stopped while there are two active timers, here starting from “Start 1”.
4) Trip can be automatically reset when the first timer from “Start 1” is finished. Motor start is
possible when all pending trips are reset. Supervision continues with a new timer from “Start 4”

Loop environment Temperature protection
MC510 extends the module hotspots module MT561 to monitor the ambient temperature inside the
drawer and prevent the drawer components from being too high, thus causing the drawer to burn
down. MC510 monitors the temperature of drawer environment to decide whether to trigger
environmental temperature protection alarm.
For details, please refer to the hotspots module MT561 section of the extended module user guide.
When MT561 is only used for loop environment temperature protection, there is no need to
configure hotspots temperature sensor.
Hotspots temperature protection
By extending the module hotspots module MT561, MC510 monitors the temperature of the inserting in
the drawer to prevent the temperature of the drawer from being too high, which leads to the burnout
of the drawer.
The single insertion temperature measurement is realized by inserting a fixed temperature infrared
sensor IR. MC510 monitors the temperature of one primary connector to decide whether to trigger a
temperature protection.

Busbar temperature protection
MC510 monitors the copper temperature in the switchgear by extending the module MT564 to
monitor the copper temperature in the switchgear, including the main busbar, the copper platoon of
the ACB cabinet, and the copper row of the fixed circuit.
The bus temperature measurement is realized by self-powered wireless temperature measurement
module WT01, and transmitted to MT564 through Zigbee. MC510 monitors the temperature of the bus
bar to decide whether or not to trigger the bus temperature protection.

Thermal protection of motor (PTC/PT100/PT1000)
The thermal protection of the motor is used as a protective condition to determine the protection
function of the PTC/PT100/PT1000 thermistor detector, which is pre buried on the stator winding or
bearing of the motor.
MC510 realizes motor thermal protection through analog input and output module MA552. MC510
according to the measured resistance value, decide whether to turn on the corresponding motor
thermal protection.

MC510 monitors the input of analog input in analog input and output module MA552 in real time, and
sends out corresponding signal according to the preset alarm level value and trip level value.
For details, please refer to the MA552 section of the analog input and output module in the extended
module user guide.
Autorestart Function
The line voltage (UL1L3) is supervised continuously. It is possible to automatically restart the motor
after momentary power loss. Two alternative models of auto restart function are provided in MC510:
Standard and enhanced.
More detailed information on autorestart function parameter, please refer to Chapter Parameter
description.
When any DI is set to "main switch state" and the main switch state is not input, the
automatic restart function will automatically fail.
FUNCTIONALITY
49
Autorestart function (standard)
In standard mode, the reaction of the auto restart function depends on the length of the voltage dip.
The following cases show the different reactions of MC510 in different voltage dip situations.
Case 1: Voltage dip< autoreclose time
Fig 40 Autorestart (Voltage dip< autoreclose time)
If voltage is restored within the autoreclose time, the motor will be restarted immediately.
Case 2: autoreclose time<voltage dip< Max. power down time
Fig 41 Autorestart (autoreclose time<voltage dip< Max. power down time)
If power is restored after autoreclose time but before max power down time, motor will be restarted
after the staggered start delay time.
FUNCTIONALITY
50
Case 3: Voltage dip> Max. power down time
Fig 42 Restart (Voltage dip> Max. power down time)
If supply voltage remains below restore level long enough and exceeds max power down time, no
automatic restart will be initiated.
Autorestart function (enhanced)
If the voltage dip is taken more serious, the enhanced autorestart function can be applied.
In the enhanced mode, the reaction of the auto restart function not only depends on the length of the
voltage dip, but also the number of voltage dips within short period of time.
The following cases show the different reactions of MC510 in different voltage dip situations.
Case1: Voltage dip< autoreclose time
Identical to Case1 of standard mode
Case2: autoreclose time<voltage dip< Max. power down time

Modbus TCP Failsafe Functionality
MC510 failsafe function supervises the network interface and connection to the remote devices
controlling the motor/starter equipment by MC510. Remote device have to refresh the certain MC510
network input variable to indicate that the control is operating normally and the network interface is
in good condition.
If a loss of Modbus/TCP communications for preset timeout value (1-25 seconds) is detected, the
failsafe activates with the parameterized function as follows:
• No operation
• Start motor direction 1
• Start motor direction 2
• Stop motor
When communication failure is detected and activated by MOSBUS TCP failsafe mode, MC510 will
automatically release remote control permissions (if remote control authority has been selected).
IO BUS Failsafe Functionality
MC510 failsafe function supervises the network interface and connection to the extension modules by
MC510. Remote device have to refresh the certain MC510 network input variable to indicate that the
control is operating normally and the network interface is in good condition.

MC510 Control Authority
Control Authority
MC510 Control Authority is the term describing the privileges on allowing motor control operation
through MC510. It is also a setting parameter in MC510 to define which control access group has
privilege to operate the motor via MC510.
FUNCTIONALITY
53
Control Access
There are three control access groups defined in MC510,
Local Hardwiring: MC510 accepts its commands from the hardwired inputs
Remote Fieldbus: MC510 accepts its commands from PLC or higher control system via fieldbus, i.e.
MODBUS/TCP.
MP Control: MC510 accepts its commands from operator panel MP5x which locates on the front panel
of each starter unit on switchgear.
CHMI Control: MC510 accepts its commands from CHMI (MV570).
Assign Control Authority
There are several means in MC510 to assign control authority and decide which control access group
has the privilege to control.
Local/Remote control authority assignment
Parameter Setting:
Select the access group from parameter setting window (Fig 44). This is the most direct option where
control access is defined by parameterization software.
Fig 44 Parameter Setting of Local/Remote of Control Authority
Multi control access group is supported!
For MC510, only when no DI is assigned Loc/R, Soft Local/Remote could be selected.
FUNCTIONALITY
54
Local/Remote Selector Switch
MC510 supports hardwired local remote selector switch function which allows selecting control access
groups via hardwired inputs. To enable this function, one of the digital inputs has to be defined as
‘Loc/R’ in MC510 (Fig45).
Fig 45 Assign “Local/Remote” function to Digital Input
Local/Remote Selector Switch will then define if control access goes to “Local “(Local Hardwired) or
“Remote” (Remote Fieldbus). This function does not include the selection of operator panel MP control
which is independent of either “Local” or “Remote” and has to be further defined in this case.

When “MP control” is enabled in one of the DIs, the MP control access option will be gray out.
In another word, Hardwired Selection has privilege over Soft in terms of assigning control
authority.
FUNCTIONALITY

CHMI control authority assignment
The choice of CHMI control permissions is completely independent of local / remote selection. MC510
provides 2 ways to define control permissions for CHMI human-machine interface, such as parameter
setting through software or input signals through hard wire switches.
Parameter Setting

FUNCTIONALITY
57
Main switch protection function
The main switch protection function is based on the protection function of MNS drawer handle
operation. This function monitors the state of the main switch under different motor circuits and
enhances the functional safety of the MNS system.
If you want to turn on the protection, you need to connect the main switch status and the test
position status to the DI of MC510. In this case, the action performance of MC510 is as follows:
Motor

Stop Normal Normal Normal Normal Normal Main switch trip
When MC510 monitors the test position, the "T" will appear on the top right corner of the
MP51 LCD.
The main switch state can be individually connected to MC510 without the need to access the test
position. In this case, MC510 only monitors the state of the DI, and the performance of MC510 is as
follows:
Motor Status Main Switch State
CloseOpen OpenClose
Running(Current feedback) Main Switch trip --
Running(contactor feedback) Main Switch trip --
Stop Normal Normal
The test position state can be accessed to MC510 individually without requiring access to the main
switch state. In this case, MC510 monitors the main switch in real time. When the main switch is in the
test position, MC510 monitors the three-phase current and the "I/O" point state, and allows the
contactor control loop to be controlled, but all protection functions based on current and voltage are
invalid. When the input of the switch is defined as the "test position", if the input point is the same as
the set state, the main switch is in the normal working position; on the contrary, the main switch is in
the test position. For example, if the contact type is normally closed, when the input is high, the main
switch is in the normal working position and the high level is cancelled. However, when the main
switch is in the test position but MC510 detects the current (>5% Ie), all the protection functions will
be automatically opened according to the set parameters, while ignoring the "test position". The
action performance of MC510 is as follows:

Logic Block
MC510 provides freely programmable logic block functions to carry out additional logic functions for
your application.
Logic block function provides several logic modules:
•True table 2I/1O
The function block is used to define the logical relationship between 2 input signals and 1 output
signals.
•True table 3I/1O
The function block is used to define the logical relationship between 3 input signals and 1 output

Maintenance Function
MC510 provides maintenance function for motor by supervising running hours, start numbers, trip
numbers and SOE.
When the maintenance parameter over the predefined alarm level, MC510 will trigger an alarm signal
accordingly. The operation of separate maintenance functions is independent thus these functions
can be active and given an alarm at the same time.
Number of Starts
MC510 counts number of starts. For each startup, MC510 updates the number of starts in memory
map. When start number alarm level exceeds, MC510 will issues an alarm.
FUNCTIONALITY
61
Motor running time
MC510 counts motors running hours. When running hours exceeds, MC510 will issue a “running time”
alarm.
Insertion cycles
MC510 gets the value of insertion cycles via counting control power cycles. When times of
Insertion cycles exceeds alarm level, MC510 issues an alarm.
MC510 also provides some other maintenance information of motor, which will convenience users to
get the report of motor.
Number of Trips
MC510 counts number of trips and updates in memory map.
Parameter change counters
MC510 counts times of parameter change and updates them in a memory map.
SOE
MC510 provides event recorder data for up to 256 events with time stamp.
Metering and Monitoring
MC510 provides an extensive range of motor operation supervisory functions. Supervisory data are
transmitted via MODBUS TCP to the upper level system for centralized management and also can
directly displayed on the operator panel MP51 if installed on the front of the motor starter module.

MODBUS/TCP
MODBUS/TCP is MODBUS over TCP/IP protocol. It is mainly used the monitoring and control of
automation.
MODBUS/TCP implemented in MC510 follows the specification below,
- Modbus application protocol V1.1b
- Modbus Messaging on TCP/IP Implementation Guide V1.0b
Refer to 1TNC928207M0201 for the MODBUS command supported by MC510.
MC510 supports 4 ODBUS/TCP master at the same time.
Modbus/TCP connection
Two-port Ethernet switches are integrated inside MC510. It makes system integration flexible and
econic. Three topologies are supported,
-Start
-Daisy chain
-Ring

Designation Description
Type of cable Straight or crossed category 5 shielded twisted
pair
Maximum cable length between two adjacent devices 100 m
Maximum number of devices per network segment 160
Maximum number of devices per ring 50
Table 44 Network characteristics
The same network segment must have the same network identifier. For example, 192.168.1.x
is in the same network segment, while 192.168.1.x and 192.168.2.x are not in the same
network segment.

Topologies
Following figure illustrate the typical topology support by MC510.
Fig 53 Topology
Using ring topology in withdrawable cubicle
The drawers have the characteristics of low downtime. In the low voltage switchgear, the protection
and control equipment of a motor starter are all installed in the same drawer. When the circuit fails,
the user can replace the equipment quickly and conveniently to reduce maintenance hours. Moreover,
ring topology will ensure that replacing any one drawer will not affect the communication quality of
the whole system.
But if two drarwes are withdrawn, as shown in right part of fig 54, even if the system has MRP
redundancy function, the situation is totally different. Devices between these two drawers cannot be
accessed anymore.
Here MS571 should be used to ensure stable communication even if two or more drawers are
withdrawn, as shown in left part of fig 54.The MS571 is mounted in the cable compartment instead of
mounted inside the drawer. When draws are withdrawn, MS571 will bypass the withdrawn drawer
automatically to keep communication working in ring.
When the drawer withdraws, the network will spend less than 200ms to re-organize a new
network.
COMMUNICATION
67
Fig 54 Ring topology in withdrawable cubicle
No more than 5 consecutive drawers can be withdrawn in the same ring, otherwise, the
quality of communication will be affected.
Loop switch MS571
The loop switch is used for keeping the Ethernet loop healthy while the withdrawable module with
MC510 is removed. As shown in left part of fig 55, there are 4 RJ45 ports in MS571, 2 ports with MCU
mark are MCU interface to connect to MC510, 2 ports with BUS mark are BUS interface to connect in
Ethernet loop. The principle is shown as right part of fig 55, MC510 is introduced into the Ethernet
loop via MS571. When MC510 is removed, MC510 will be auto bypassed by MS571, so that the ring
Ethernet loop is still available.
COMMUNICATION
68
Fig 55 Loop switch MS571
The power supply of MS571 is provided from the BUS interface. As shown in fig 54, TA60
should be used for connecting the first and last MS571 to external device in one loop.
Directly connecting external device to “ETH BUS” port of MS571 may damage the device!
MS571 could not bypass MC510, when MC510 lose power.
TA60
Fig 56-1 TA60
The power supply of MS571 can be provided via TA60, there are 3 ports in TA60: RJ45 modular
plug, RJ45 modular jack, and two pair’s redundancy power cables. RJ45 modular plug is used to
connect to external device. RJ45 modular jack is used to connect to MS571 to provide power
supply and Ethernet loop signals. Two power cables should be connected to two redundancy

24VDC power supplies. The red core is 24VDC+ while the black core is 24VDC- for each power
cable. In case there is only one power supply, both power cables should be connected to this
power supply.
Fig 56-2 TA60 connection
Directly connecting external device to RJ45 modular jack of TA60 may damage the devices!
When the power supply is provided via TA60, the connection quantity is limited to maximum
50 MS571 modules, or maximum 4 MS572 modules. And the total cable length of power over
Ethernet should be less than 100 meter.

This is the reference data at rated voltage and frequency. The value is given on the motor rating plate
and does not affect operation of the MC510.
Motor Nominal Current (N1/2)
Range: 0.08(0.01)63.0A or 0.5-1.0 Iprim or 0.25-1.0 Iprim
Default Setting:4A
Related Parameters: Motor Information / Motor Power Rating
Motor Control / External CT parameters
Description:
This is the rated current In of the motor, at rated load, at rated voltage and frequency. The value is
given on the motor rating plate. The rated current can be set within this range.
N1 setting is related to “External CT Primary” and “External CT secondary” settings under “Motor
Control”.
Setting range without selecting external CT option is from 0.08-63A. In the case that external CT is
selected, the range is dependent on the primary and secondary of external CT, ie, If “External CT
secondary” is set to 1, the range varies from 0.5 to 1.0 of CT nominal primary current. If “External CT
secondary” is set to 5, the range varies from 0.25 to 1.0 of CT nominal primary current.
Example: In the case of an external current transformer Primary of 100A, the range varies from 50 to
100A when external CT secondary is selected as 1. The range can also be from 25-100A if secondary of
5A is selected.

Description:
MC510 supports different kinds of motor connections. This parameter need to be set according to
type of control desired for the motor.
More details of MC510 starter types is described in Chapter Function.
NR-DOL: Non Reversing Direct On Line.
NR - Non Reversing means that the motor only runs in one direction.
NR-DOL/RCU: Non Reversing Direct On Line RCU starter
RCU stands for Remote Control Unit. This is a starter type where contactors are allowed to be directly
hardwired controlled by control device located near the motor in parallel with MC510 control. In
another word, this starter allows motor being controlled by remote control device even if MC510 is not
in operation.
REV-DOL: Reversing Direct On Line.
REV- Reversing starter supports motor runs in both directions (clockwise CW, counter clockwise CCW).
PARAMETER DESCRIPTION
91
REV-DOL/RCU: Reversing Direct On Line RCU starter
In addition to NR-DOL/RCU, this starter supports motor runs in both directions.
ACTUATOR: Actuator starter is for controlling valves, dampers, actuators by using limit switches.
NR-S/D: Reduced voltage starting in star and running of the motor in delta after meeting the
transition conditions.
Star-delta starters are used mainly to restrict the starting current of a motor due to supply limitations.
The motor is started with the winding connected in star and transferred to delta after the
"Changeover time". The starting at a lower voltage also reduces shocks on the motor coupling, belts
and the gear mechanisms. The starting current and the torque are reduced to 1/3 of the DOL value.
However, it must be determined whether the reduced motor torque is sufficient to accelerate the load
over the whole speed range.
NR-2N: Non-reversible two speed motor separate winding. Two speed drives are used for applications
requiring dual motor outputs. NR-2N is the starter designed for two separate winding motors.
Current measurement for NR-2N utilizes two sets of external CTs measuring current from main supply.
External CTs can be selected separately for both motor windings.
NR-2N Dahlander: Non-reversible two speed motor Dahlander connection
Two speed drives are used for applications requiring dual motor outputs. NR-2N Dahlander is the
starter type designed for motors with Dahlander connection.
Autotransformer: Non-reversible motor starter based on reduced voltage via auto-transformer.
Autotransformer starter supports motor starting with reduced voltage thus providing reduced motor
startup current. In a result, the starting torque is reduced accordingly.
NR_Softstarter : Non-reversible Softstarter Control
Softstarter applications are for controlling motor accessory softstarter device. MC510 gives start and
stop commands to the softstarter unit. The softstarter is set for adjusting motor voltage with its own
parameters. More information about softstarter can be found in softstarter manual.
Rev_Softstarter: Reversible Softstarter Control
Functionality of this starter type is according to NR-softstarter starter with support for reversing use
of motor.
Contactor Feeder: Feeder control by contactor.
When a “Start” command is given, the internal relay CCA remains closed until a stop command is given.
The internal relay CCB & CCC has no function here.
PARAMETER DESCRIPTION
92
Contactor Feeder /RCU: Feeder control by contactor On Line (remote control of the contactor,
bypassing the MC510).
The “Start CW” command closes the internal relay CCA 1sec respectively. The stop command will close
relay CCC for 1 sec. The wiring of the self-auxiliary contact across the start command latches the
contactor.
Removing the MC510 from the starter will not prevent RCU operation depending however on the
connection (external relay and/or switch is used for start and stop). The stop pulse issued by the
MC510 will override the RCU-switch start position.

Simple Network Management Protocol
In typical uses of SNMP one or more administrative devices, called managers, have the task of
monitoring or managing a group of hosts or devices on a network. Each managed system executes, at
all times, a software component called an agent which reports information via SNMP to the manager.
SNMP agents expose management data on the managed system as variables. The protocol also
permits active management tasks, such as modifying and applying a new configuration through
remote modification of these variables. The variables accessible via SNMP are organized in hierarchies.
These hierarchies, and other metadata (such as type and description of the variables), are described
by Management Information Bases (MIBs).
An SNMP managed network consists of three key components:
•Managed device
•Agent: software which runs on managed devices
•Network management station (NMS): software which runs on the managed
A managed device is a network node that implements an SNMP interface that allows unidirectional
(read-only) or bidirectional (read and write) access to node-specific information. Managed devices
exchange node-specific information with the NMSs.
An agent is a network-management software module that resides on a managed device. An agent has
local knowledge or management information and translates that information to or from an SNMP-
specific form.
A network management station (NMS) executes application that monitor and control managed
devices. NMSs provide the bulk of the processing and memory resources required for network
management. One or more MNSs may exist on any managed network.
SNMP supports the following types of messages between and manager and the agent:
•Get Request: A manager-to-agent request to retrieve the value of variable or list of variables. Desired
variables are specified in variables bindings (values are not used). Retrieval of the specified variables is
to be done as an atomic operation by the agent. A response with current values is returned.
•Set Request: A manager-to-agent request to change the value of a variable or list of variables.
Variables bindings are specified in the body of the request. Changes to all specified variables are to be
made as an atomic operation by the agent. A response with (current) new values for variables is
returned.
•Response: Returns variable bindings and acknowledgement from agent to manager. Error reporting
is provided by error-status and error-index fields
•Trap: Asynchronous notification from agent to manager. SNMP traps enable an agent to notify the
management station of significant events by way of unsolicited SNMP message.

Motor Grouping
In the case of conventional switchgear, the operator can start or stop a process by sequentially
starting or stopping of the motors. The required delay between the motors is introduced either
manually or with the help of a timer and serial interlocks. This would increase the operators’ time,
cabling and the initial cost of the starter.
With help of intelligent system, the operator could start or stop the process with a single group
command. The start and stop delay can be set for individual motors. The serial communication with
logical connections between devices reduces the cabling, process interlocks and the hardware. In case
of abnormality in any motor of the group, a group tripping would follow.
In this context, a motor group means a collection of motors, which are operated by an individual
group start or stop command. The successful start of the motor group is indicated.
Individual start/stop command from fieldbus can also be given to the devices located in the
group as well as via the switches connected to the device I/O in the local mode.

Description:
This value determine when MC510 takes the Operation after detected the input signal. If this value is
not 0, the MC510 will wait an Operation delay time then to take the Operation. If this value is 0, the
MC510 will take the Operation as soon as the input signal is detected.
Function Type 2
PLC control1/2
When the function is set to "PLC control 1" or "PLC control 2", and when the action signal is monitored,
the motor will continue to run in one direction or at a given speed until the opposite stop signal is
received.
"PLC control 1" allows the motor to rotate or run at low speed.
"PLC control 2" allows the motor to reverse or run at high speed.
If you want to turn on the PLC control function, you need to set the control authority to local hard
wiring.
TOL Bypass
If the thermal overload bypass function is selected and the signal input function block is detected by
MC510, the thermal overload bypass instruction of the motor is issued.
When the TOL bypass function is activated, MC510 allows the thermal capacity trip level to rise to
200% temporarily, that is, the motor can run continuously when the heat capacity is less than 200%,
and does not trip the motor, or allows the motor to start immediately when the heat capacity is less
than 200%.
If the TOL bypass function is to be activated, TOL bypass function must be enabled at TOL protection
window in MCUSetup, and then TOL bypass signal should be given to TOL bypass function block or
from fieldbus. The signal is a level detection mode.
TOL bypass function increases the thermal capacity trip level value, which may cause the
equipment to overheat or even burn down.
Protection Bypass
If the protection bypass function is selected, MC510 will detect the signal input function block and
issue the protection bypass instruction. At this time:
Motor is running. When MC510 detects the protection bypass signal input, all protection functions
that allow the protection bypass are switched to alarm only mode automatically. When the protection
bypass signal disappears, all the protection functions that allow the protection bypass are restored.
Protection with protection bypass is during trip delay time. When MC510 detects the protection
bypass signal input, the delay calculation will stop immediately. When the protection bypass signal is
lost, the delay calculation will restart if trip signal is still available.
PARAMETER DESCRIPTION
121
The motor is tripped, but the trip is not cleared. When MC510 detects the protection bypass signal
input, the trip will be reset immediately. When the protection bypass signal disappears, the trip
information is redisplayed if the judgment condition of the trip is still available.
After the bypass is protected, the motor may run under dangerous conditions. Please be
careful when using it.

Limit1/2
This function is used to install the limit switch. When the function is activated, the motor stops, and
the motor can only reverse control. That is, the limit switch 1, which limits the positive or low speed
operation of the motor, and the limit switch 2, which limits the motor reversing or the high speed
operation of the motor. The function is a level trigger mode.
PARAMETER DESCRIPTION
122
Torque switch
When the function is set to torque switch, when the input signal is opposite to the setting state,
MC510 will release all control relays to stop the motor. This function is a level trigger mode.
External trip
This function is used to define the external tripping signal, which will cause the motor to trip. When
the signal is effective, the motor is tripped and needs to wait until the signal is lost before it can be
restarted. The signal is a level detection mode.
When the input point does not detect the external tripping input signal, MC510 will reset
automatically.
MP Control
This function is used to decide whether the operation panel can control the motor. When the function
is set to "MP control", the control authority of MP can’t be changed by parameter settings, and is
determined by the state of the input signal of the function. If the input signal is effective, the
operation panel MP can control the motor and vice versa. The signal is a level detection mode.
CHMI Control
This function is used to decide whether CHMI can control the motor. When the function is set to "CHMI
control", the control authority of CHMI can’t be changed by the parameter settings, and is determined
by the state of the input signal of the function. If the input signal is effective, CHMI can control the
motor and vice versa. The signal is a level detection mode.
Loc/R
This function is used for local / remote state control.
For MC510, if the local / remote input function is valid, the control permissions are local hard wiring; if
the signal is invalid, it is a remote bus. The signal is a level detection mode.
Test switch
This function is used to monitor whether the main switch is in the test position. If the main switch is in
the test position, MC510 monitors the three-phase voltage and the various "I/O" point states. MC510
can control contactors, but all protection functions based on current and voltage are automatically
closed, and only the control loop is tested.
When the current value of the monitor is not 0, all protection functions set by the parameter will
automatically turn on. This function protects the motor in the case of contact failure.
The contact is a level trigger mode.
Opening the "test position" function will trigger the monitoring function of the main switch to turn on.
The function of the main switch can be seen in detail as the main switch protection function in
Chapter Functionality.

output, analog input and output. Extension modules are mounted beside MC510 basic module and
exchanges information via a serial communication interface called IO bus. The MC510 range of
products supports following modules:
1) DIDO, module which provides Digital Input Digital Output interface
2) AIAO, module which provides Analog Input Analog Output interface
3) Hotspots measurement, module which provides Infrared Temperature sensor to measure the
contacts/bus-bar temperature.
4) WTM, module which provides function to measure the bus-bar temperature and transfers data to
basic module via radio.
5) RCM, module which provides function to measure the residual current and over current protection.
For details, please refer to Extension module user guide.
Thermal Overload Protection (TOL)
MC510 protects the motor by calculating the thermal image of the motor both during running and
stop. This image is used to allow optimal performance of the motor with calculated time to trip.
The thermal image is calculated based on the highest of the three measured phase currents and
depends on the parameterized data such as trip class (t6), motor ambient temperature (TAMB), cool
down time factor (Mt6)
Motor ambient temperature is taken into account for thermal image calculation by means of a device
internal parameter TFLC. Where, TFLC is the highest of the measured three phase currents related to
motor ambient temperature.
When the thermal capacity level reaches the setting of trip level (e.g.100%), the thermal overload trip
will occur. The TOL trip can be reset after the thermal image goes below the motor reset level. The
motor can be restarted only after TOL trip is reset.
When the motor is being stopped, the thermal image calculation continues by using the background
heat level and cooling down time factor until thermal capacity level decreases to zero. The thermal
capacity decreases at a constant rate till it reaches the background heat level, after which it depends
on the parameters trip class, and cool down time factor. Thus, simulating cooling down of the stator
winding and the iron body of the motor.
During power failure, the thermal capacity level of the motor is stored in the memory and the cooling
down calculation starts from this level after resumption of power.
TOL Protection conforms to IEC 947-4-1, i.e with a motor current 1.05xTFLC running for 2 hrs will not
cause TOL-trip and subsequent rise in current to 1.2xTFLC will cause trip within 2 hrs.
In case of unbalance situation, the fictitious negative sequence current in remaining phases is taken
into TOL calculation to trip early.

Description:
The thermal model can be selected as either standard or EEx e. The standard model makes use of trip
class, startup I ratio and motor startup time in TOL calculation. Parameter trip class definition defines
the trip time for 6x motor nominal current (In) and it must be less than defined cold state maximum
value for the motor.
The protection of explosion proof three-phase induction motors with type of protection ‘increased
safety’ EEx e is done with two special parameters, the stall/nominal current ratio (Ia/In ratio) and te
time. The tripping time of the TOL protection from the cold state motor must be less than the te time
rated for the motor.
For EEx e thermal model a set of parameters have fixed values or are not available in order to simplify
parametering instructions and parametering process while providing a secured protection
functionality. This should be carefully considered by the user since the given parameter value do not
have effect to functionality in this case.
These are following parameters are not available when EEx e mode is selected:
TOL Protection / Motor ambient temperature:Fixed 40°C
TOL Protection / TOL bypass command:Disabled

Trip Class (T6)
Range: 3 (1) 40 s
Default Setting: 6s
Related Parameters: TOL Protection / Thermal Model (standard)
Motor Information / Nominal Current (In)
Motor information / Motor Ambient Temperature
Description:
Parameter trip class (t6) is the basic setting of the thermal protection function. For user it provides
the possibility to set the thermal model characteristic according to motor startup requirements and
characteristic. With trip class parameter user defines the time that protection allows current of 6x In
from cold condition for protected motor.
Motor start-up is the most common occurrence of the short overload situations. Normally two starts
from cold condition and one start from a hot condition are permitted. The Trip class (t6) value can be
set according to one cold start, which allows easy setting of protection.
The Trip class (t6) time for protection is defined based on the motor maximum start time, which is
informed by the manufacturer.
Initial information required for Trip class (t6) definition.
– Motor startup current ratio (rated motor data, Is/In), see parameter Startup I ratio
– Maximum start time permitted for cold motor
– Maximum start time permitted for warm motor
– Motor ambient temperature, see parameter Motor ambient temperature.
Example 1. A thermal protection is set for a motor M2BA315SMC, 110 kW.
– Motor startup current ratio (Is/In) 7,5
– Maximum start time for cold motor 30 s
– Maximum start time for warm motor 15 s
– Motor ambient temperature 40°C
With the initial information the protection characteristic can be defined by the following procedure.
First, the motor start current is calculated according to the ambient temperature. Practically, with
40°C of ambient temperature, the following calculation for start current can be passed. For more
information of ambient temperature coefficient see table of maximum permitted current in chapter
“Ambient Temperature”.
Temperature coefficient is derived with the following routine. Since the motor ambient temperature in
the example is 40°C, the TFLC is 1.00 x In.

axis, while the maximum permitted time for cold motor start is set on the vertical axis. The cross point
of these constraints shows the maximum setting for Trip class (t6).
The received setting is the absolute maximum value without further considerations and a lower value
can be selected. A longer start is not protected by thermal protection and additional protection
against stalled rotor is necessary. In case of thermal protection trip at start, with the setting of
maximum Trip class (t6) value, it is recommended to check the motor size for extreme start
requirement.
Now, the setting of 40 second is limited by the range of parameter. Value for Trip class (t6) is derived
from the cold condition time/current diagram, see the picture. This setting allows start time up to
approx. 26 second for cold motor, before a thermal protection trip occurs. The start time for a warm
motor, with this parameter setting, can be read from the hot condition time/current diagram
accordingly. The check routine is shown in the latter picture.
The warm condition start must be within motor ratings. In this case, the start time for a warm motor
is approximated from the latter picture and must be shorter than 12 second, as read from the picture.
In practice, start lasting longer than 12 second, will lead to trip from the thermal protection.

More optimized setting of the thermal protection is needed in case of one start for warm motor is
required. In this case the Trip class (t6) parameter is derived from the warm condition time/current
diagram according to actual duration of motor start and motor startup current.
The derived Trip class (t6) value is verified from the cold condition time/current diagram to ensure
that thermal protection trip time is less than maximum allowed start time for a cold motor, i.e. the
protection is well defined.
There is a need to arrange a separate protection for unsuccessful start, i.e. stalled rotor, if the thermal
protection characteristic allows longer start before trip than is allowed for the motor. Then stall
protection is utilized for a cold motor start supervision. By defining the operation of Startup time and
stall protection Trip delay the trip must be set before motor maximum start time is exceeded, in case
of unsuccessful start.

Description:
The safe locked rotor time te of a particular induction motor is the time necessary for the winding
temperature to rise from its final operational value to a fixed maximum value determined by the
corresponding temperature class of the motor during locked rotor. It is of particular significance when
the overload protection is specified for motors destined for use in hazardous locations. The te time is
for EEx e motors to withstand Ia/In current.
The parameter value for trip class te time is as rated for EEx e motor in the data book which
represents the maximum value. Parameterized value for trip class te time can be equal or less than
motor rated te time. For a faster trip value less than rated is selected.
With Ia/In ratio this parameter makes it possible for MC510 unit to calculate the trip time of the motor
according to the load. MC510 calculates the trip time for EEx e motor automatically, but the trip time
for a certain current for further investigation can be defined as presented in this chapter.
Trip time can be defined with the help of following cold condition time/current diagram. Diagram is
according to TOL standard model cold condition.
Initial information, as parametrized, is required.
Ia/In ratio for EEx e motor
te time for EEx e motor
When Ia/In ratio is placed on the current (Is/TFLC) axis and te time is placed on the time (t) axis, the
co-ordinate on which the lines drawn through these points cross each other is located on the t6 curve.
According to defined t6 curve trip time vs. motor current are available from cold condition
time/current diagram. The same t6 curve can be used for defining the trip time from a hot condition
time/current diagram, as well.
For example: Ia/In ratio for EEx e motor is 7 and parameter te time value is 7 seconds. By using the
following cold condition time/current diagram t6 curve can be found. When t6 curve is defined other
trip times vs motor current are available.
Motor ambient temperature is not observed because it does not have affect in TOL EEx e module
usage, thus Ia/In can directly be used (see parameter Ambient temperature).
The readout is t6 curve which is either existing in the diagram or is an estimation below the defined
point. In this case Trip class (t6) = 9 seconds is estimated from the example picture below and is
drawn to the diagram. Trip time for current 3xIn is estimated approx. 40 seconds.

Related Parameters: --
Description:
For an accurate thermal image of the motor, MC510 needs to know the characteristics of the motor to
be controlled. Different motors in different environments need different time periods to warm up and
to cool down. The cooling down period for a stopped motor is usually about four times longer than
the warm up period and it certainly differs within the motor, e.g. in certain hot spots of the windings
from the iron core. But this value can be different depending on dirt or other material covering the
motor, motor body size, weight installation place, etc.
The normal value for the parameter is between 4…8 describing the slower cooling for a stopped
motor [curve 1 and 2] than cooling of a running motor [curve 3]. In practise, this has been discovered
as the normal rule for motors covering various applications.
However, if motor manufacturer gives recommendation for another value, it may be set to the
protection.
For example: External cooling system is installed for improving the cooling down of a stopped motor.
Furthermore, according to statement from motor manufacturer cooling time constants for a running
and stopped motor are equal. Thus the parameter can be set below recommended value 4 [curve 1].

be loaded to the same thermal capacity. Normally this reduction of output power is done
automatically by MC510 but it is also possible to do it manually which is instructed later in this chapter.
To calculate the thermal image of the motor being protected, the MC510 needs to know the
temperature of the environment in which the motor is running. Especially in industries, where the
motors are located near the heat source, the maximum thermal capacity level of the motor is reduced
based on the increased surrounding temperature.
Motors designed for EEx e applications are always rated and certified for a certain maximum ambient
temperature, most commonly 40°C. If EEx e motor is designed for other temperature manufacturer
will supply the motor rated data.
Because of the nature of EEx e motor the output power ratings are not reduced automatically
according to ambient temperature by MC510. Instead of using ambient temperature parameter
MC510 uses fixed value 40°C, thus multiplier is one (1) when TOL EEx e model is selected.
The MC510 reduces the maximum permitted current by the multiplier as indicated in the table below
(TOL standard model).
Ambient temp. °C 40 45 50 55 60 65 70 75 80 Ambient temp. °C

= In x
1.00 0.96 0.92 0.87 0.82 0.74 0.65 0.58 0.50 Permitted
output, % of rated
output
For example: The thermal capacity level of the motor reduces from 100% at 40°C to 85% at 50°C.
Therefore, the motor can be loaded maximum to 92% of its rated load at 50°C.
Manual reduction may be needed if other reduction multiplier than presented in the table above are
required. Output power reduction is done by setting the value 40°C to parameter motor ambient
temperature and calculating the temperature reduction directly to nominal current. When multiplier is
calculated this way it must be applied to trip class time as well (Is/TFLC).
For example: Motor data sheet specifies that in 60°C motor can be loaded maximum of 75% of the
nominal. Thus motor ambient temperature is set to 40°C and when setting the nominal current the
rated motor current is derated,
xInrrentnominal cu 75.0
When nominal current is derated trip class parameter is defined with the same factor. It should also be
considered that other parameter’s, i.e. protection function trip and alarm levels, referring to nominal
current are effected relatively.
Stall Protection
Stall protection is used to protect the driven mechanical system from jams and excessive overloads.
Under such conditions, the motors have to be switched off in good time and reported to avoid undue
mechanical and thermal stress on the motor and the installation.
This protection function is active only after the motor has successfully started or after parameterized
motor startup time has elapsed and will cause relay activation in case of a motor stall while it is
running.
The parameter can be set to a higher value for application experiencing overload as part of normal
operation.

Phase Failure Protection
Phase failure in motor phase currents is a common phenomenon in industrial environment. It generally
occurs because of pitted contacts in the contactor or SCPD, imbalance in the mains supply, loose
connections, blown fuse, and faults within the motor. It is an extreme situation where a complete loss
of phase occurs. This can be caused by a utility supply problem or by a blown fuse in one phase.
Unbalanced phase currents are a major cause of motor thermal damage due to the nature of the
current. The negative sequence current induced in the rotor is of double the power supply frequency
and produces a counter torque to the desired motor output. For small unbalances, the overall output
torque will remain same as motor develops a large positive sequence torque to overcome the negative
sequence torque. This opposing torque and the high negative sequence current lead to an increased
temperature rise in the rotor and stator.
Reasons for the phase failure are neither temporary nor self-covering. Although TOL protection
performs an accelerated trip during phase failure and unbalance over 20%, there are no good reasons
to wait for the trip to occur through TOL protection. By the use of phase failure protection a motor
can be tripped without waiting for thermal calculation. Indeed, phase failure protection should be
parameterized to trip in shorter time than TOL does.

Underload Protection
Underload protection function monitors the process against loss or decrease in motor load. This

for pumps, broken belt for conveyors, loss of airflow for fans, broken tools for machines etc. Such
states do not harm the motor but early diagnosis helps to minimize the extent of damage to the
mechanical installation and subsequent loss of production.
The motors on underload draw mainly the magnetizing current and a small load current to overcome
frictional losses. Therefore, the other reason to isolate the motors on underload is to reduce the
reactive load on the power system network.
Underload protection function is based on the highest measured phase current.

Noload Protection
The noload protection function protects the process against sudden loss of load. Though this

The no load current is of the order of 0.2 to 0.6 In depending on the size and speed of the motor. The
no load current of slow speed motors is high and that of large motors is low.
The noload protection function is based on the highest phase current measured by the current
measurement unit. The noload protection function detects missing current with respect to the
contactor and the main switch ON feedback and executes actions as parameterized.
Noload protection is active only after the motor has successfully started, i.e. when current is detected.

Earth Fault Protection
The earth fault protection function protects the motor and the network against Earth Fault Current
flow. During earth fault, the motors can reach a dangerous potential above the ground level thus
posing safety hazard to personnel. The earth faults are mainly caused due to ageing of the insulation,
deterioration of insulation due to sustained or cyclic overloading, moisture or conductive dust. Most
insulation faults result in leakage to the frame of the motor. Earth fault protection in MC510 device
provides the protection for fatal isolation damages.

Undervoltage Protection
The undervoltage protection function protects the motor against overload during voltage dips. During
a mains undervoltage, the electrical energy required to drive the rotor remains same for some period
owing to its inertia.
According to the energy conservation law,
Mechanical energy= Electrical energy
Where, VL is the motor line voltage, IL is the motor line current and Cosphi is the power factor.
From equation 1, the motor draws more current during voltage dips to deliver the same mechanical
energy.
The motors switched off during voltage dip or power failure can be restarted on power resumption
sequentially to prevent simultaneous switch-on of the motors and thus prevent another mains failure
on the network. The tripping of motors due to undervoltage of short duration can be bypassed. The
feature also would help to restart the process on power resumption by sequentially starting the
motors (staggered start).
The Undervoltage protection also prevents startup of the motor if the voltage is not high enough and
indicates phase loss before switching ON the motor.

Maintenance
Preventive maintenance is the best way to have long service life for any equipment. Maintenance
function can be configured suitably as a reminder for preventive maintenance. This would reap high
benefits to the user in terms of reduced process down time and loss due to stoppage of production.
Maintenance function indicates the operation of the motor in terms of hours run and the usage of
starter in the form of operating cycles. Number of hours run helps to assess the bearing life and its
lubrication or replacement, whereas the number of operating cycles help in deciding replacement of
worn-out power contacts or the contactor itself.
Maintenance alarm can be activated after lapse of the set counter. The counters can be set after
maintenance according to two different principles depending of course on normal routine of the user.
Running Time Alarm Level
Range:0 (1) 65,535 h
Default Setting:65535(Disabled)
Related Parameters: --
Description:
The user can set a period after which a preventive maintenance is desired. When the Running timer
exceeds the preset running time alarm level, an alarm message ‘Running time’ is generated for the
corresponding MC510. This helps to lubricate and maintain the bearings of the motor within the
correct service interval.
When the parameter is set to 65535, the running time alarm is disabled.

carrying out preventive maintenance of power contacts.
When the parameter is set to 65535, the start number alarm is disabled.

User Definable Map
The MC510 contains a User Definable area in the memory map. This area allows re-mapping of the
addresses of any Actual Values or Setpoints registers. The User Definable area has two sections:
1. A Register Index area (memory map addresses 13D0H-141FH) that contains 80 Actual Values or
Parameter register addresses.
2. A Register area (memory map addresses 0100H-014FH) that contains the data at the addresses in
the Register Index.
Register data that is separated in the rest of the memory map may be re-mapped to adjacent register
addresses in the User Definable Registers area. This is accomplished by writing to register addresses
in the User Definable Register Index area. This allows for improved throughput of data and can
eliminate the need for multiple read command sequences. The User Definable Register Index is stored
as a parameter and therefore it is “remembered” even when the power is removed.
For example, if the values of phase L1 current (register address 0030H) and Motor Status (register
address 0019H) are required to be read from a MC510, their addresses may be re-mapped as follows:
Write 0030H to address 13D0H (User Definable Register Index 0000) using function code 06H or 10H.
Write 0019H to address 13D1H (User Definable Register Index 0001) using function code 06H or 10H.
It is now possible to read these two data registers with one read, at addresses 0100H, 0101H. Address
0100H will contain Phase L1 Current and address 0101H will contain Motor state.
