Auto Tuning Initiated at start-up, this feature interrogates the motor and establishes motor specific

information which insures optimal performance without complex programming

Auto Fan Control Senses control voltage, auto configures fan, and controls based on need


Modes of Operation – Starting Modes• Sensor-less Linear Acceleration• “Enhanced” Slow Speed: 1% to 15

Modes of Operation – Linear Speed

“Patented” Sensor-less Linear Acceleration Starting Mode Accomplished via Advanced Motor Speed Estimation Algorithm

– No external feedback required - reduces cost and potential for failure– Provides exacting motor acceleration control under varying load conditions

Simple to set up– 2 parameters required to configure: Ramp Time and Initial Torque (used as reference)– Reduces/eliminates the need for the Dual Ramp mode

Always uses the minimum amount of energy needed to accelerate the motor in the time requested

(regardless of the loading condition)

Linear Accel vs. Torque Control: High Inertia Load

Parameter Settings: =Start Time: 10 second

Torque Pulse/Mechanical Wear and Tear

Higher Peak Current

Time

2 Sec/Div = ~10 Sec 2 Sec/Div = ~4 Sec

Current more stable and less disruptive to power system



• Simplest Starting Mode

• Lowest starting current profile per start

• Ideal for any application

• No Sensor required for speed feedback

• Provides control over both torque and speed, for unmatched motor starting performance

• Selected start time closer to actual than any other stating method** With other modes, if the controller senses that the motor has reached full speed (UTS) before completing the selected ramp time, it will automatically switch to providing full voltage to the motor.


Modes of Operation – Stopping Modes

• Sensor-less Linear Deceleration

• External Braking Control

• Coast• Soft Stop• Pump Control• Smart Motor Braking (SMB)• Slow Speed with Braking• Accu-Stop

Modes of Operation – Stopping Modes

Linear Deceleration Easy setup Improved performance versus Soft Stop or Pump Control No Sensor required for speed feedback

– Reduced cost – Lowers probability for failure– Provides exacting motor deceleration control under varying load conditions

Least amount of energy use for controlled stop

External Braking External brake activated in concert with Stop command

– Aux relay output enables external brake– Ensures coordinated control via SMC

Braking parameter allows setting braking time for application

SMC-50 Advanced Diagnostics

Motor and Controller Faults and Alarms Areas of advanced diagnostics

– Motor and controller protection, (e.g., motor overload, motor jam, starter SCR overtemp)– Power and energy monitoring (e.g., power quality, total harmonic distortion)– User-defined preventive maintenance (e.g., time to perform PM)– System configuration/option modules (e.g., I/O configuration changed to invalid)

Fully configurable Alarms and Faults(1) – Ability to individually enable or disable alarm and fault – Ability to individually adjust the alarm and fault trip level– Individually configurable Fault and Alarm delay times(2) to limit nuisance trips – Ability to individually enable automatic restart from a Fault

• Configurable “Restart Attempts” counter to limit the number of unsuccessful restarts• Restart delay time defines a delay from when the Fault occurred until a restart attempt can occur

21

(1) A Fault condition results in a system shutdown, (motor stops) whereas an Alarm can be used as a warning (motor keeps running) to alert an operator of a pending Fault condition and to take appropriate action.

(2) Not available on all Alarms and Faults
