1.1 Function keys and paging key

The function keys (5) have different meanings and effects in various modes of control. These

keys are used to select main and submodes, then they may get another function after the proper

mode is selected.

Horizontal lines next to the keys point to a definite area of the screen. Current meaning of eachfunction key is written on the screen in the field to which the line points.

In case when function keys mean mode selection, meaning of function keys is immediately

overwritten after selection of the proper mode (key is pressed).

According to the mode selected either the submode menu possible in that mode is written next

to the function keys, in which entry is possible by depression of the proper key, or, if there is no

subsequent level, a well defined meaning, function, is given to the keys according to

requirements of the selected mode.

For example, the MPGX text is written next to the uppermost function key in manual mode. If

X axis is to be moved with the handwheel, the area next to the key is lit up on the screen when

key MPGX is pressed, thereby indicating that this function has been selected.Sometimes several (non-exclusive) functions may be selected at a time. Under such conditions

the screen areas next to several function keys are operated in inverse mode.

The selected function can be cleared in one of two different ways.

- The function can be turned off by pressing the selected function key again.

(The screen area next to the key is indicated in normal state.)

- If a choice is to be made between mutually exclusive functions, pressing

another function key will clear the previous one.

The paging key is used to leave the mode given. When it is pressed the control goes higher

always with ONE selection level. First, it moves to the sub-mode selection level (if the given

main mode has sub-modes), then, on repeated depression, the main mode selection level follows.

1.2 Controls for manual movement

Controls for manual movement are as follows:

$" jog keys (14)$" main spindle drive control keys (10)

Controls of the manual movement are ineffective in the following cases:

$" actual program execution,

$" data input,

$" error condition,

$" EDIT mode, (PROGRAM) (except for spindle stop key )

$" TEST mode without execution

The controls can also be used in program suspension (STOP) status. At this time CYCLE

START causes control unit to take up again momentary status valid at suspension, resetting first

the main spindle rotation (and simultaneously the coolant) status, then position of coordinates(linear movement with rapid traverse, the last 1 mm with feed).

1.2.1 Jog keys

The jog keys can be used to realize axial movement. If none of functions labelled 1, 0.1, 0.01 is

selected on the screen, the carriage moves to the appropriate direction until the direction key is

pressed

$" with rapid traverse, if the key is simultaneously pressed as well.

$" with current feed rate values written in F address, if rapid traverse key is not used.


8/143


4

Rate of movement is influenced by position of the "FEED RATE OVERRIDE" (3) switch.

The continuous movement stops when the direction key is released independently of position of

the rapid traverse key. The value written at address F is interpreted in n/minute. Simultaneouslyseveral axes are movable, if several direction key are pressed.

1.2.2 Keys used for main spindle drive control

The main spindle drive keys can be used to start rotation of main spindle in the proper direction:

M3 M4 resp, the main spindle can be stopped: using the key. The main spindle

stop is also effective in EDIT mode. The main spindle speed is defined by value written in the

S address and override status of the main spindle speed ( ).

1.3 Data input keyboard

The data input keyboard can be applied in the following cases:

$" MANUAL (manual) in this mode it is usable to write a single block.

$" EDIT (program and data input) in this mode it is usable to write, modify and search program

and parameters, resp, for block search.

$" AUTOMAT it is usable to specify sequence number of block to be searched.

$" TEST in this mode it is usable to define parameters of graphic display, or for block search or

to specify the sequence number of block to be found.

$" STOP in this condition it is usable to change function values.

Apart from cases listed, depression of data input keyboard is ineffective.

1.3.1 Rules for use of data input keyboard

Numbers are entered according to rules below:$" the written number assigns a value to the address visible in bottom line of the screen (data

input field),

$" left side zeros are not needed to be written in,

$" the digit written is interpreted as an integer before pressing decimal point, but afterwards as

a decimal,

$" in case of right side insignificant zeros after decimal point, or, an integer value, the decimal

point is not needed to be written in,

$" actual partial value of number entry can be seen in bottom line of the screen (data input field),

$" the I/M and keys (if enabled) can also be pressed many times during a number input, any

time before closing the number input ( ).

Default value: positive, absolute value. Symbol of incremental data input is visible in first

position of place before the number being entered, while sign is displayed in the second

position.

$" The control unit displays DATA? error during number input, if number of integers or

decimals that can be provided for the given address is exceeded, or, if on data input of the

given address use of the , or keys is illegal.

$" With the use of CLEAR key, the commenced number input can be cleared any time

before termination. If it is cleared, the status preceding commencement of number input is

restored.

$" On depression of or CLOSE NUMBER INPUT keys the address being in bottom line


9/143


5

of the screen assumes the value which has been entered before use of closing keys.

Effect of and CLOSE NUMBER INPUT keys differs from each other in the

following:

$" if is pressed the address string moves forward,$" if is pressed the address string moves backward.

In addition to closing of number input, the keys can be used to move address string without

number input as well. In case of block entry, value of skipped address remains unchanged,

while on execution the displayed function changes.

$" The and CLOSE BLOCK INPUT keys load the edited block from the buffer store

into the program store:

$" as a new block, if there is no proper sequence number in the block store,

$" as a modification, if there is identical sequence number,

$" clears block with identical number, if the block is empty in the buffer store.

Their effect prevails primarily in program editing mode (EDIT).

causes program store to continue editing with its following block,

causes program store to continue editing with its preceding block.

When using the keys the control unit makes you move automatically always to the beginning

of the address string.

$" After depression of BLOCK/SEQUENCE NUMBER SEARCH key the block sequence

number should be provided and the entry process should be closed with the use of or

CLOSE NUMBER INPUT keys.

Effect:

$" in EDIT mode it may cause block with specified sequence number to be modified,

$" in TEST or AUTO mode it may cause block search to occur.

Use of key before closing also cancels selection of N address.$" The INCH/METRIC key shifts inch or metric system of data input. In default value the

data input, or its display has

$" metric system for metric ball screw,

$" inch system for inch pitch ball screw (display is made with 2 decimal accuracy in the

former case, while with 4 decimal accuracy in the latter case).

The changed status is valid until the key is repeatedly pressed. The system of units in

which the input process is performed is displayed by a M (metric) or I (inch) character written

in top line of the screen. The key affects display of all the coordinate values, and F address.

$" The CLEAR key

$" clears the started number input, restoring the preceding status,

$" clears value of displayed address during block input even before starting the number input,

$" releases error condition.

Caution! Clear of G address results in clearing the full block.

$" The key is also suitable for cyclic stepping of the main block types in addition to

selection of the incremental data input. (GTYP 90;G00, G01, G02, G03, G40, G50, G60,

G70, G80).

$" The key is suitable for cyclic stepping of the subtype versions in the main type versions

in addition to the decimal point input: (G70, G71, G72, G73, G74, G75, G76, [G77, G78 with

piston lathe only]).

1.4 Controls of execution

$" The EMERGENCYSTOP (1) key disconnects the machine from the control, stops all kinds

of machine operations. Its use will interfere directly in the electric control of the machine tool,

bypassing the control unit.$" The CYCLE START key causes the following to occur:

$" single block written in MANUAL mode is executed,

$" zero point assignment is prepared,

$" program execution is started in TEST or AUTO mode (automatic execution),

$" suspended execution is resumed.

The accepted cycle start is indicated by illuminated state of green LED above the key. Apart

from cases listed, use of key is ineffective.

$" Effect of the CYCLE STOP key prevails only in execution (if lamp of CYCLE

START key is lit). It suspends program execution and produces a socalled STOP status. The

suspended execution is resumed if START key is pressed. During thread cutting

movement or for programmed disabling of suspension (M97 status) the key is ineffective.

$" The feed rate override (3) switch can be used to change feed value realized by the control unit:

$" 0 through 100% for rapid traverse,

$" 0 through 120% for work feed,

$" ineffective for thread cutting, or in M97 status!

At 0 position of the switch the feed stops (except thread cutting), and it is resumed only if the

switch is turned away.

In AUTO mode, if the RAP.OV.DISAB. function is selected for rapid traverse, its effect

doesn`t prevail, except for 0 position of the switch.

$" The MAIN SPINDLE SPEED OVERRIDE keys are effective only if infinitely

variable (electronic) gear is applied, except in thread cutting, and M97 status.Pressing the 100% key, the programmed main spindle rotation is assumed.

Using the + or key the mains spindle rotation is incremented or decremented in 10% steps

in the 50 100% range. It is ineffective if the speed doesn't reach minimum value of speed,

or exceeds maximum value of speed, which is defined by manufacturer of the machine in the

parameter store, or by programmer at SMAX address for M96.

1.5 Information on use of keyboard

Keyboard of control is of repetitive type except for the jog keys (14). This means that if

somebody presses a key, its effect subsequently prevails immediately. If the key is kept pressed

further on, the effect prevails again after a definite delay (Typematic Delay), if the key is still

kept pressed the keyboard enters code of key with definite frequency (Typematic Rate) in CPU

of the control over and over again.

The operator can set delay and frequency in the parameter field according to his needs.

Position of jog keys (14) is interchangeable except for the rapid traverse key. (Refitting of keys

requires removal of front panel of the device.) The parameter field can also be used to specify

which key position shall represent "+" or "-" direction of one of the axes.

1.6 Informations displayed on screen

The screen (2) is able to work in two kinds of display modes. In alphanumeric mode it displays

numerals, letters and other characters.

In grapich mode it can trace the tool path based on program entered. In this mode, it also writesalphanumeric informations on the screen in addition to the drawing.

Characters and texts written on the screen may be as follows:

$" normal video, that is, character is white, background is black (e.g general purpose

information)

$" inverse video, that is, character is black, background is white (e.g. to highlight something)

$" blinking, in order to have display to attract attention (e.g. programming errors or machine

defects).

In graphic mode shade and colour of lines may be different.

1.6.1 Informations displayed on screen in alphanumeric mode

Field 1: Current meanings of function keys are labelled in 8 fields of equal size being at right

edge of the screen. The 8 fields are graphically framed.

Field 2: Used to write current main mode or SELECT status.

Field 3: Used to write current sub-mode or status (STOP, COMPILE). Unless a sub-mode

belongs to the given main mode, this field is blank.

Field 4: Identifier of program being in program store of control: letter "L" and 4 digits

maximum.

Field 5: Letter "M" in this field means that display/data input is to be meant by metric system,

letter "I" refers to inch system. The display changes with the use of key.

Field 6: The label is LATHE, that is, the control has been made for lathes.

Field 7: This field is used to write various messages, errors.

Field 8: Block number display: Letter "N" and 4 digits maximum. In TEST and AUTO mode

it displays sequence number of block being executed.

Field 9: Here it is displayed whether the reference point assignment has been done. If letter "R"

in the middle of field is in inverse video mode (character is dark, background is light),

the reference point assignment has not been done. If letter "R" is in normal video mode

(character is light, background is dark), the reference point assignment has beeen done.

Field10: In this field the time spent with actual cutting in AUTO mode is displayed in

hourminute dimension. Its value is deleted when the control is turned on.

Field11: In this field informations relating to the machine, except EDIT mode, are displayed

(positions of axes, feed rate, main spindle rotation, tool code, etc.,). In EDIT mode listof already edited and closed blocks, and the general purpose listing area gets here.

Field12: It is an area used for the following:

MANUAL mode: to display single block, TOOL mode : (tool data input) to list values

included in the selected compensation group, REF P mode : blank, EDIT mode : to

display listing area, resp, block buffer for program editing, TEST and AUTO: to list

program beginning from AUTO mode block being executed, STOP status: an area used

to list changeable addresses.

Field13: General purpose data input area. It is used on MANUAL, TOOL, EDIT program

editing, resp, in STOP status, otherwise it is a listing area.

1.6.2 Informations displayed on screen in graphic mode

Graphic display is possible in TEST and AUTO modes. In TEST mode, the tool path can be

traced based on program stored in the program store.

In AUTO mode, if the tool path has already been traced in TEST mode, the machining process

can graphically be followed.

Field 1: The current meanungs of the function keys are titled in eight equal field (boxes) at

the right edge of the screen. The eight boxes are framed graphically.

Field 2: Printing the current main mode.

Field 3: Printing the current sub-mode.

Field 4: Identifier of program in the program store of the control (character "L" and max. 4

digits).

Field 5: Character "M" in this box means that the display and the data input refer to metric

units; character"I" refers to inches. The printing can be changed over by means of key

I/M.

Field 6: Contains the title LATHE. This means that the control has been designed for use with

lathes.

Field 7: That box can be used for printing various messages, errors.


13/143

Field 8: Printing record number (character "N" and max. 4 digits). In TEST or AUTO mode

it will display the sequence number of the block being executed.

Field 9: Printing in AUTO mode the assumption(assignment) of the reference point. Character

"R" blinking in the middle of the box indicates that the reference point has not beenassumed (assigned). A normal character "R" (light character, dark background) refers

to the completion of reference point assumption.

Field10: In AUTO mode, the actual fine spent in machining (cutting) is displayed in this box,

in hours:minutes. Its value is cleared by the control at the time of power/on. In TEST

GRAPHIC sub-mode, the test executed after function key NORMAL has been pressed

will display the time of machining in minutes:seconds; otherwise the value displayed

refers to AUTO mode.

Field11: X coordinate of upper edge of the graphic field (13) in mm or inch dimension.

Field12: Z coordinate of right edge of the graphic field (13) in mm or inch dimension.

Field13: Area of graphic drawing. Movement of tool path is traced among coordinate limits

shown in fields 11, 12, 14, 15.

Field14: X coordinate of lower edge of the graphic field in mm or inch dimension.

Field15: Width of work space shown in the graphic field in mm or inch dimension.

Field16: Data input area in TEST GRAPH mode. On drawing, resp, in AUTO mode, it displays

current value of X, Z coordinates.

Field17: Displaying the current values of coordinates X and Z in plotting and AUTO modes.

1.7 Control status display

If control gets to SELECT status after

poweron, the screen displays the

following status:

The SELECT status is displayed in the

main mode field (2). The current soft-

ware version number that operates in the

control is displayed in the center of the

screen. At the right edge of the screen

the first six function keys allow the six

main modes to select:

MANUAL: manual mode

AUTO: mode for automatic execu-

tion of part programs

Pressing any of the function keys the

control assumes the selected mode,

unless there is an error display.

The seventh function key (DIAGN) is a

special diagnostic mode, whose

description is contained in the

"Technical and Installation description".

The eighth function key (MACHINE

ON) can be used to turn on electric units

of the machine tool. After its depression,

if poweron was successful, the field

illuminates.

After poweron the contol unit may send

$" M: shows valid M functions per group.Field 12 of the screen displays address string of the recommended G90 block type when entering

in the mode. If the block type is changed (G90 function is overwritten), address string of the new

block type is displayed.

The G90 address is offered in data input field 13. The number input keyboard 8 can be used to

change G type or, stepping the address string, a value can be assigned to any address using thekeys. After the data input is closed (use of keys ) the new, next / previous address appears

in field 13. The entered value appears in field 12 beside the appropriate address.

3.1 Special cases for manual movement

The manual movement can be realized with the main spindle drive keys (10) and jog keys (14),

as well as with the handwheel if any is mounted on the machine. Fundamental cases of manualmovement are discussed in paragraph 1.2.

If the operator wants to move with handwheel along one, or possibly several axes at a time, he

has to press the MPG (Handwheel) function key having the proper symbol. The selected MPG

area is lit up. Repeated depression of the key clears enabled state of the handwheel on the given

axis, the selected MPG area becomes dark. Selecting one of functions designated as 1, 0.1, 0.01,

the selected axis moves 1, 0.1, 0.01 mm, respectively, on revolution of one pitch of the

handwheel.

For incremental jog the selected text is lit on depression of the proper function key (1, 0.1, 0.01),

while on single depression of jog keys the selected axis performs a movement of 1 mm, 0.1 mm

or 0.01 mm, respectively, in turn in the appropriate direction.If the function S.JOG is selected, on depression of one of jog keys X, Z slow rotation of the main

spindle is started, if one of the keys is released the movement is stopped.

3.2 Entry of single blocks

In reset status of this mode address string of the G90 (function block) block type is

recommended.

In case of this block type:

$" The control unit immediately (without pressing CYCLE START) assumes the entered

function value after the data input to the displayed address is closed (for example, if T

address is changed it performs turret tool position change, while if S address is changed,

it performs main spindle speed change, etc., ).$" Stepping on G address with data input, selection of a different block type can be initiated.

If a block type other than function block is selected, the control unit:

$" executes the instruction on depression of CYCLE START key after entry of a directly

executable, full block. After its execution the entered value will remain, while for

incremental data specification repeated depression of CYCLE START key results in

repeated execution.

$" an error is displayed if a geometric calculation that may infer more than one instruction

blocks (programenvironment) is specified relating to execution of the block.

$" If G address is overwritten or deleted, then a new block can be programmed.

In this mode, controls of the manual movement can be applied in a manner described in

paragraphs 1.2 and 3.1: the main spindle is startable and stoppable, the axes can be moved

continuously, incrementally and with handwheel.

First two digits of T address: tool number (code)

If a number of 4 digits is written on T address, for example: T01nn, where nn = 00 99 (entry

of leading zero(s) can be omitted), after data input with or key is closed the tool with

specified number (1) is put to working position on the machine and tool compensation marked

nn is called in.

Second two digits of T address: code of tool compensation group Writing two digits on T

address, for example: T12, no tool change is made after the data input is closed, only the

specified tool compensation group (12 in our case) is called in. Up to 99 various tool and 99

various tool compensation groups can be manipulated on the control.

The address string elements can be selected with and keys, except for skipping tool

address, which is feasible with keys and Data can be entered with the numeric keypad.

The tool calibration has two fundamental cases:

$" tool calibration inside lathe

$" tool calibration outside lathe.

4.1 Tool calibration inside lathe

The procedure is as follows:

1. The cutting tool is clamped in the tool holder according to the machining position,

2. The tool code and code number of tool compensation group (4 DIGITS) are specified by

data input to T address. It causes an actual tool change.

3. The tool clamped in the tool holder is touched to a surface, whose size is known in

coordinate system of machining, of the clamped workpiece in X then Z direction (with

manual movement).

4. According to the selected direction of touch, coordinate value of known size surface of

the workpiece is entered in X then Z addresses. (During entry, programmed point of the

tool is just located at the coordinate value of given size.

5. Subsequently, nose radius value valid for the given tool is written in R address.

6. The value written in C address cannot be deleted and cannot be overwritten with zero

data either.

7. The procedure is repeated separately for tools present in the machining program.

LNotes:

$" On data input to address T and on entry of a tool code, the position change is

immediately carried out for a tool change system of turret tool if key is

pressed.

$" On data input to address T four (4) digits have to be specified even if the tool is in

machining position.$" If tool calibration is made by touching one of base surface areas of the workpiece, it

is recommended to drive the main spindle in order to protect cutting edge from

damage.

$" The coordinate values written in addresses XTR* = Xm, ZTR* = Zm in data input field

13 will be displayed as actual positions in field 11 under the (ACTUAL) text after

the data input process is closed.


22/143


18

$" In field 12, where data of the selected tool compensation group are displayed,

compensation values Xk, Zk are displayed at address X, Z, which is calculated

automatically by the control unit after the data input process is closed,

whereXm; Zm current position in coordinate system of the workpiece (a value visible in field 11).

Xk; Zk tool compensation, which means offset of zero point of workpiece coordinate

system in relation to nose of tool in the given compensation group (a value visible

in field 12).

4.2 Tool calibration outside lathe

For tool calibration outside lathe, tool and compensation group codes assigned to each tool, as

well as data to be specified on addresses X, Z, R, C are contained in a table. The procedure is as

follows:

1. The tool compensation group is selected by data specification on address T (BY MEANS OF

TWO DIGITS ONLY, so that the control unit does not perform the calculation given in

point 4.1, but stores direct the the entered value).

2. Data of table are entered in turn on addresses X, Z, R and C.


23/143


19

3. Operations described under steps 1 and 2 are repeated for each tool compensation group.

4. Subsequently, zero point offset fixed to the workpiece is determined in relation to reference

point of tool holder located on the reference point. A measuring tool is changed by nn00

code (nn may not be 0) entered on address T, of which compensation values are known.The tool nose is touched to known size point of workpiece clamped in the chuck. Sum

of distance from touch point to workpiece zero point (Xm;Zm) and overhang of the given

tool (Xk;Zk) are entered in address XTR*, ZTR* in data input field 13. This causes

control unit to calculate distance between declared reference point of tool holder residing

at the zero point (reference point) and the zero point of workpiece, that is it calculates the

zero point offset (Xn;Zn), which is displayed in field 12. The position display under the

(ACTUAL) text in field 11 shows distance of declared reference point of tool holder

measured from zero point of the workpiece. (Xm + Xk = Zm + Zk, that is, it shows the

value entered.)

The zero point offset calculated so and stored at address X, Z on group code TOO is

effective at call of every other compensation group and compensation of the selected


24/143


20

group is added to this value.

As for special function of T00 compensation group, see paragraph 4.4 (Zero point offset)

in detail.

LNotes:$" As for display of tool length compensation values, the particulars stated for tool

calibration inside the lathe are valid.

$" The tool length compensations are signed quantities, their magnitude and sense (sign)

are determined by position of declared reference point of the tool holder in the

coordinate system fixed to the tool nose.

$" The tool compensation values can also be loaded from a cassette in EDIT mode.

When loading from cassette the zero point offset is also reloaded.

$" On entering or loading tool length compensations on cassette, the carriage may be in

any position.

4.3 Modification of tool length compensations (Wear compensation)

Tool compensations are to be modified because of the deviations of machined workpiece from

the specified dimensions (for example, dimensional error due to tool wear). The modification is

possible in TOOL CALIBRATION mode, by an appropriate INCREMENTAL data input to X,

Z or R address (that is, with signed value of the deviation) after calling of the proper

compensation group on address T. This modification can be accomplished in arbitrary position

of the carriage.

If size of the machined workpiece is larger than specified, the compensation value should be

decreased (data input with negative increment), if smaller, the value should be increased (data

input with positive increment).

4.4 Zero point offset (G61, T00)

The zero point offset can be realized by programming block type G61 and data input to addresses

X and Z in

$" MANUAL mode or

$" EDIT mode in the part program.

In order to make the system consider zero offset, the block entered has to be executed. Zero offset

can also be performed in TOOL CALIBRATION mode by selecting T00 compensation group

and data input to addresses XTR*, ZTR*. The control unit interprets data entered in addresses

XTR*, ZTR* in field 13 as direct zero point offset, the entered value gets to field 12, while the

current position is calculated in the new coordinate system in field 11. On the contrary, if the

compensation group is called in by Tnn00 data input (nn may not 0) (combined with tool code

reference), the control unit automatically calculates the zero point offset from the value entered

in address XTR*, ZTR* and momentary position of the carriage, based on paragraph 4.2, which

gets into field 12, while the entered value is regarded as current position (display of field 11).

Execution of zero offset is necessary:

$" for tool calibration outside the lathe to specify relative position of workpiece, or tool holder

coordinate system,

$" for shifting the coordinate system of workpiece (since not the individual tool compensations

are modified separately).


25/143


21

External tool calibration

The position of cutting point of tool in coordinate system of workpiece is calculated and

displayed by the control unit according to the relationship below:

Xa = Xo - Xk - XnZa = Zo - Zk - Zn

where:

Xa, Za are the current coordinate values in coordinate system of workpiece, displayed in

field 11

Xo, Zo are values recorded within the control unit:

for external tool calibration:

$" momentary position of declared reference point of tool holder in relation to its

position occupied at the zero point (reference point) in coordinate system

of the zero point (reference point);

for internal tool calibration:


26/143


22

Internal tool calibration

$" momentary position of tool nose in relation to its position occupied at the zero

point (reference point) in coordinate system of the zero point (reference

point;

Xk, Zkare tool compensation values displayed at Tnn address (nn may not be 00) in field12,


$" position of declared reference point of tool holder in a coordinate system set

to the tool nose;

for internal tool calibration:

$" partial shift of zero point of workpiece in relation to tool nose at the zero point

(reference point) in coordinate system of the zero point (reference point);

Xn, Zn are values of zero offset along X and Z axes displayed on address T00 in field 12,

that is,


27/143


23


$" position of starting point of workpiece coordinate system in relation to

declared reference point of tool holder at the zero point (reference point)

in coordinate system of the zero point (reference point);for internal tool calibration:

$" shift of starting point of workpiece coordinate system in relation to tool nose

at the zero point (reference point), in coordinate system thereof.

All components are to be interpreted as signed quantities according to sense of the coordinate

system concerned.

GRID = for grid point zero, the zeropoint is assumed on the grid

point (at rotary encoder zero

pulse) that is nearest the actual

position of the carriage.

Selecting the proper mode the screen

displays the following information after

pressing the function key: if REFRNC is

selected:

If FLOAT or GRID is selected only the

text of submode is changed.After the submode has been selected,

manual movement is possible in a

manner described in paragraphs 1.2 and

3.1. Before zero point assignment is

commenced, the carriages must be

moved to the proper position with

manual movement.

Then, process of zero point assignment

is as follows: After CYCLE STARTkey is pressed, depression of jog keys

(14) finds special significance, the axisassuming zero point can be selected by

them. For REFRNC and GRID the

machine moves to the reference switch

or grid point in the direction defined on

its installation. The zero point

assignment has to be started separately

for each axis. For FLOAT no carriage

movement occurs. If zero point has been

assumed on both axes, the control unit


30/143


26

changes automatically to TOOL CALIBRATION mode. Mode of zero point assignment may

differ with each axis.

The carriage movement can be stopped even during zero point assignment with the

CYCLE STOP key. If there is not movement the paging key is effective!The zero point assignment doesn't delete zero point offset. The machine power on/off deletes

zero point offset only if the compensation store becomes damaged (TCORR error). Before zero

point assignment a reduced rapid traverse is valid for any kind of axis movement. The control

may send different error displays for zero point assignment, which are discussed in paragraph

10.2.

Termination of EDIT mode

When the program has been corrected, entered or loaded, the control performs running of

program segment assigned to termination of EDIT mode after the paging key is pressed.

This program segment

$" checks syntactically (formally) correct completion of address string of blocks, ERROR

DISPLAY occurs if no value was written in one of addresses to be completed

compulsorily (value limit is checked only right at data input). The control unit indicates

an error even if the technological program begins with a positioning relating not to both

axes. This positioning block may at most be preceded by a coordinate shift of typeG60G61 or a function block.

$" performs geometric calculations defined by continuous sequence of blocks, ERROR

DISPLAY occurs if sequence of blocks is not conform to the specification, or the

calculations cannot be performed. After the error display is released, you are prompted

to correct block with erroneous sequence number (in case of sequence error the previous

or next block is possibly displayed).

$" finally, new blocks are inserted in the program for each roundingoff, or edge chamfering (in

case of programming to B address).

During time of the above activity the COMPILE status is displayed next to the EDIT title in field

3 of the screen. As long as this text is visible the keyboard is not usable.

IF an ERROR occurs, the following is made after the error is released:

CASSETT function key after entry,

contents of screen are as follows:

Fields 11, 12 and 13 always show list of

program residing in the part program

store.

Corresponding to value of L address

detailed in point 6, second line of text of

the first three function keys shows texts

PRG, PLC, PARAM or TOOL. As a

preparatory measure for readin,

position yourself before the program to

be read in on the cassette (with manual

tape movement) and connect the

recorder to the control unit via socket (7)

on the front panel. Using the READ

function key, select readin status, then

start readin with function key START.

Both function keys are lit. Start playback

on the recorder with pushbutton PLAY.

The control unit searches the next sync signal on the cassette. The readin process can be stopped

with function key STOP (reset status of CASSETT submode is returned).

Recognizing the sync signal the program is loaded.

During load the following are checked:$" START signal per byte

$" cross parity per byte

$" longitudinal parity

$" program length (number of bytes)

$" checksum of program

If load is successful, the system goes to reset status of EDIT mode, first page of the actually

loaded program is visible on the screen.

As a preparatory measure for write, position yourself to a location selected for store on the

recorder (with manual tape movement), and connect the recorder to the control unit.

Using the function key WRITE select write status, then start write process with RECORD

pushbutton on the recorder.

When the cassette tape is already in motion, the function key START causes control unit:

$" to wait 10 seconds for acceleration of cassette tape, then write sync signal,

$" to write desired program together with the necessary verification signals,

$" finally, to enter in reset status of CASSETT submode.

For blank cassette (or if playback is not started), the operation can be interrupted with function

key STOP, and the control returns to reset status of PROGR sub/mode.

parameter field. (See Technical and

Installation Description.) On readin the

control automatically recognizes the

incoming code (ISO or EIA). The

endofline terminating character has to

be selected also in the parameter field.

Data and programs must meet severe

formal requirements. Requirements

relating to part programs and tool

compensation data are comprised in

manual titled Programmer's Manual,

while those relating to parameter data

and interface programs are included in

manual titled "Technical and Installation

Description". Possible error messages:

reaching the lower or upper limit position, the list of programs will be rolled upward or

downward automatically. The selected identifier number is displayed in inverse. After selecting

the program, then pressing function key START, the program is reloaded. After reloading is

completed, beginning of the loaded program is listed and the previous program in the programstore is lost.

Selecting SAVE function, then activating function key START, the program residing in the

program store is transferred to the background store. Several programs with identical program

number can be stored in the background store. If the background store is full and the new

program can no longer go in it, the control sends a FULL? error message.

Selecting DELETE function it is possible to delete the program from the background store.

(Selection: see LOAD function). Pressing function key START, the selected program is deleted.

Selecting LIST function, the program with selected identifier is listed on the screen on

depression of START function key. The keys , can be used to step forward/backward per

7.1 Execute "dry run" program

without command issue

After entry into the submode contents

of screen are as follows:

SINGLE BLOCK: execution per block.

COND. BLOCK: conditional block,

COND.STOP: conditional stop, refer to

description of AUTO mode as

for effect of these function keys.

START function key causes control to

scan program execution without

issuing either move or other

commands to the machine tool.

SINGLE BLOCK: by validating this

function key the control stops at the end

of each block (STOP position),

$" displays coordinate values to be

reached at the end of block in

field 11,

$" while it displays function values

valid in the block on the function

indication.

The automatic block search can be

executed in this STOP position as well(status without execution remains, but

after block search the SINGLE BLOCK

function key is to be pressed again), but

no manual movement, resp, function

overwrite is possible. The STOP

position can be released with the use of

START function key.

7.2 Display tool path on screen

After pressing the function key the

screen changes to graphic mode.


44/143

After the function key NORMAL is

selected the function keys will be redefined,

and starting draw operation with STARTkey after this, the workpiece being in the

program store will be drawn in field 13 so

that all the tool movements find room in the

graphic field.

If a detail of tool path drawn in such a way

is wanted to blow up, a box may be shrunk

on the desired detail by keeping

Block search is possible based on

informations described for AUTO mode.

The rapid traverse movements are

displayed with halftone traces, while pathsections made with feed appear with

heavier traces.

In STOP status after block search and

before pressing START function key, a

small bright crossmark indicates the

drawing process holds.

Positive direction of Z axis always points

to right edge of the screen. Positive

direction of X axis may point to upward and downward as well, depending on the design of the

machine. (This is shown in the parameter field, if DSPX=0 the direction points up, while if

DSPX=1, down). When "2" is written for parameter DSPX, axes X and Z will be interchanged.

This

facility is used with a vertical carriage (caroussel) lathe.

After depression of AUTO function key

the screen is as follows:

Contents of field 14 are identical to

those described for MANUAL mode.

Fields 12 and 13 displays list of program

being executed, with block being

executed in the top line.

8.1 Continuous execution

Changing to AUTOMATICEXECUTION mode, the program

residing in the program store is started

and is continuously executed on

depression of CYCLE START key.

When end of program (P2 command) is

reached the main spindle stops rotating

and initial status of AUTOMATIC

EXECUTION mode is again established.

The program can be restarted with the

CYCLE START key.

8.2 SINGLE BLOCK: block-by-block

execution

Pressing the SINGLE BLOCK:

execution per block function key at any

time during the AUTOMATIC

EXECUTION mode (display field is

lit).the control unit:

$" still completes the block being

executed (only the full block, it


48/143


44

will not stop after partial cycles, or blocks of partial cycles),

$" establishes program suspension status (STOP position) automatically after execution of the

given block. In STOP status the informations described in paragraph 8.4 are valid.

During execution, repeated depression of SINGLE BLOCK function key (display field becomesdark) as well as end of program (P2) cancels status of stepwise execution, and the program will

again be executed in continuous mode.

8.3 COND.BLOCK: conditional block COND.STOP: conditional stop

Pressing any of the function keys the display field will be illuminated (active status).

If, during execution, the control unit finds a P3 conditional stop command in one of the blocks

and COND. STOP function is activated, STOP status is established, otherwise P3 is ineffective.

If, during execution, the control unit finds a P4 conditional block command in one of the blocks

and COND. BLOCK function is activated, then the block is skipped without execution, otherwise

P4 is ineffective.

8.4 RAP.OV.DISAB.: rapid traverse override disable. GRAPH: graphic display

If RAP.OV.DISAB. function is active (text is illuminated), the override switch is ineffective for

rapid traverse (only for feed movements). An exception is "0" position of the switch, which is

effective for rapid traverse, too.

8.5 GRAPH: graphic display

If GRAPH function is active and previously the tool path has been drawn in TEST mode, then,

in graphic mode, the control uses a bright crossmark to indicate the current stage of the

machining process. The normal video (display) can be reset with function key ALPHA.

8.6.1 Options for intervening in STOP status

In STOP status (the lamp over CYCLE STOP key is lit) pressing another CYCLE STOP the

lamp goes out and the screen takes up the following status:

In field 12 of the screen address string of STOP status is validated.

Labelling of function keys is identical to those described in MANUAL mode.

Now the following interventions are possible:

1. The CYCLE START key causes program execution to continue. If, previously, position

of carriages have been changed by the jog keys (14), or the keys were used to

stop main spindle drive, the control unit assumes again the main spindle speed (according

to the earlier direction), or returns to coordinate point valid on suspension (rapid traverse,

the last 1 mm with workfeed, along the straight line that can be drawn between the

current coordinate point and the coordinate point valid on suspension).

2. The carriages can be moved with the jog keys (14) or handwheel, the main spindle can be

stopped based on those described in paragraphs 1.2 and 1.3.

3. Data can be written in address string FEED, SPIN, M, OUT, VELO, SMAX, which is

immediately validated and it remains valid until it is overwritten even if the program is

continued.

4. An automatic "search block" operation can be initiated with data entered in N address.

Relating to this, informations described in paragraph 8.4 are valid.

5. An optional mode can be selected following depression of paging key .

6. A tool compensation can be modified (even in AUTO default status) by setting up function

key TOOL CORR. with the function key pressed, a new address string can be called. (By

pressing it again, the initial address string will be restored [in AUTO default states, the

program list will be selected].)T9999 X

Z

R

At address TOOL, the control compensation group can be called.

The values entered to correction addresses X, Z and R are interpreted incrementally. Only a

number smaller than 1 mm may be defined for then. The entered correction (compensation)

values will be validated when called after positioning following CYCLE START

LNote: Manual movement, data input, block search is effective in STOP status (to prevent

accidental depressions) only if repeatedly pressing the CYCLE STOP key to turn out its lamp.

The coolant stops automatically when entering this status, however, CYCLE START causes

it to restart.

8.7 Block search

In STOP status of TEST or AUTO mode automatic block search is produced

$" by pressing the key,

$" by specifying block sequence number with number input keyboard 8a. (in field 13),

$" by terminating data input with key.

On block search the control unit

1. Invalidates the execution per block function (turns out SINGLE BLOCK title).


51/143


47

2. Scans program beginning from start of program to the block with searched sequence number

in status of "execution without data output", interpreting its commands, too, calculates

position to be reached at the end of block searched and the machine status.

3. Establishes STOP status.4. CYCLE START causes it to take up the searched machine status and the calculated

coordinate value (in straight line with rapid traverse, the last 1 mm with feed), then

continues execution from the next block.

LNote: In TEST status without execution (POSITN), or in GRAPH submode, the execution

described in step 4 is omitted.

9 Poweron reset status

9 Poweron reset status

After poweron the control unit runs test programs. During this time it checks the check sum of

fixed stores (PROMs), performs RAM test, or checks status of PLC program store and parameterstore. It gives OK indication, if finds each store segment good, resp, BAD indication, if one of

them is faulty. In case of error, the NC Ready lamp is not turned on, so the control cannot be

applied to the machine. Any of errors occurring here requires intervention of an expert. After

poweron the screen requires about 2025 seconds for warmup.

After the test programs have been run, the control unit:

$" enters in SELECT status,

$" checks program in the program store, if finds it good, it will be compiled which is indicated

by COMPILE text flashing in field 2. If the program store got damaged, MEMORY error

is indicated,

$" checks tool compensation store, and TCORR error indication is given if the store has some

error.

Subsequently, an optional mode can be selected on the control (after the error is cleared, if error

has occurred).

In its status after power on the control unit:

$" gets into absolute programming reset status

$" NC LED lights

$" In reset status of MANUAL mode address string of G90 block type (function block) will be

offered

$" X and Z values are random ones

$" displayed value of N block number is zero.

At poweron of control unit the following default status is validated in relation to thetechnological parameters

M05 = spindle stop

M09 = coolant off

M95 = there is no constant cutting rate calculation

The code before power/off is assumed as tool code, if the compensation store is faultless,

otherwise 0000 tool code is interpreted by the control unit

The status before power/off is assumed as range code.

Default values of the further function values are:

$" feed rate

$" main spindle speed

$" cutting rate

$" max. main spindle rotation are defined by constants of the parameter store. (See

Technical and Installation Description). At poweron there is no valid reference

point, value of "active time" and workpiece counter (0 address) are zero.

10 Messages and error signals

49


The control unit can send messages and error signals from three sources. They may be as

follows:$" error signals of supervisor program of control

$" error signals of NC program of control

$" error signals and messages of PLC program of control.

The errors may be different and may require other interventions:

$" fatal errors (these are error signals of supervisor program), which can be cleared only by

poweron/off of the control, but,if the cause of error still persists, the errors may appear

again and entail loss of NC ready status;

$" severe errors, which can be cleared, but they disconnect control from the machine tool (for

example, errors of measuring system), so prevent operation of the machine;

$" manipulation programming errors, which can be cleared;

$" error signals of message character, which can be cleared and machining is resumable, but,

until the error persists, they appear over and over again (for example: REC.ST);

$" or errors from PLC, which will be cleared by eliminating the cause of error (for example:

machining cannot be started until the door closing working space is shut).

Field 7 of screen is used to display errors and messages. Errors deriving from NC program may

appear in both alphanumeric and graphic modes, but in case of the other error signals and

messages it reverts to alphanumeric mode if it was in graphic mode previously.

10.1 Error signals of supervisor program of control

After power-on the supervisor program checks stores of control and if they were found good the

"OK" title is appended after the name of each store segment. If an error is found, the BADmessage is put after name of the corresponding store segment. Names of store segments are:

PROM CONTROL: SYSTEM SERVICE HGSZ PLC

RAM CONTROL: PARAMS PLC

If the control finds a faulty one of the PROMs, replace the corresponding component. Exit from

error condition is not possible.

If error is found in one of RAM spaces, then that space has to be read in again. It is advisable

to store parameter store and PLC program on a data medium readable by control. The clear key

causes control to enter in SELECT. Subsequently, the appropriate program ca be read in from

the external data medium. (Refer to Installation Description for more detailed information). If

any of errors occur, the control will not turn on its ready-to-operate signal.

The supervisor program may send error indications during operation of the control, too. These

errors are fatal, and entail loss of ready status of NC or power-off of the machine.

Errors of this type will be logged by the control. To facilitate a subsequent trouble-shooting, it

is advisable for the operator to record such errors including the time instant, the error signal

(display), the circumstances causing the error (trouble) and the remedy of trouble (if any).
