D Axis selection

To move the tool along an axis, select the corresponding axis selection

signal. Never specify axis selection signals for two or more axes at a time.

D Path memorization

When the tool is moved in manual operation along an axis, the control unit

memorizes up to ten paths of movements. If the tool is stopped after being

moved along a selected axis and is then moved along another selected

axis, the position where this switch takes place is memorized. After ten

paths have been memorized, the control unit does not memorize any

additional switching points.

D Reset

Upon reset, memorized position data is lost and the tool withdraw mode

is cancelled.

D Single block

The single block switch is enabled during return operation. If the single

block switch is turned off, continuous return operation is performed. If

the single block switch is turned off, the tool stops at each memorized

position. In this case, return operation can be resumed by turning the

operation to trace the programmed path. The retrace function also enables

the user to move the tool in the forward direction again (forward return

movement) along the retraced path until the retrace start position is

reached. When the tool reaches the retrace start position, the tool resumes

movement according to the program.

Procedure for Retrace Operation

Procedure

D Forward movement →

To move the tool in the forward direction, turn off the REVERSE switch

Reverse movement

on the operator’s panel, then press the cycle start switch. If the REVERSE

switch on the operator’s panel is on, the tool moves in the reverse direction

or completes reverse movement.

Three methods are available for moving the tool in the reverse direction

along the programmed path.

1) When the tool is moving in the forward direction, turn on the

REVERSE switch on the operator’s panel during block execution.

2) When the tool is moving in the forward direction, turn on the

REVERSE switch on the operator’s panel after a single block stop.

3) When the tool is moving in the forward direction, turn on the

REVERSE switch on the operator’s panel after a feed hold stop.

In the case of 1) above, the tool starts reverse movement after completion

of the block currently being executed (after execution up to the position

of a single block stop). Turning on the REVERSE switch on the

operator’s panel does not immediately start reverse movement.

Explanations

D Forward movement and

In automatic operation, a program is usually executed in the order that

reverse movement

commands are specified. This mode of execution is referred to as forward

movement. The retrace function can execute in reverse, program blocks

that have already been executed. This mode of execution is referred to as

reverse movement. In reverse movement, the tool can retrace the tool path

followed by forward movement.

A program can be executed in the reverse direction only for those blocks

that have already been executed in the forward direction.

Approximately 40 to 80 blocks can be executed in the reverse direction,

depending on the program.

During reverse movement, the REVERSE MOVEMENT LED is on and

RVRS blinks in the lower-right corner of the screen to indicate that the

tool is undergoing reverse movement.

The tool can perform reverse movement one block at a time when the

single block mode is set.

D Forward return

The tool can be moved again along the retraced path of the blocks in the

movement

forward direction up to the block where reverse movement was started.

This movement is referred to as forward return movement. In forward

return movement, the tool moves along the same path as forward

movement up to the position where reverse movement started.

When the tool returns to the block where reverse movement was started,

the tool resumes forward movement according to the program.

In forward return movement, the REVERSE MOVEMENT LED is off

and RTRY (Re-TRY) blinks in the lower-right corner of the screen to

indicate that the tool is undergoing forward return movement. When the

tool switches from forward return movement to forward movement,

RTRY (Re-TRY) disappears from the lower-right corner of the screen.

The tool can perform forward return movement one block at a time when

the single block mode is set.

D Reverse movement

When there are no more blocks for which to perform reverse movement

completion

(when the tool has moved back along the path of all memorized blocks

or the tool has not yet started forward movement), operation stops. This

is referred to as reverse movement completion.

Upon reverse movement completion, the REVERSE MOVEMENT LED

goes off, and RVED (ReVerse EnD) blinks in the lower-right corner of

the screen to indicate that reverse movement is completed.

830

OPERATION

B-63534EN/02

4. AUTOMATIC OPERATION

D Reset

Upon reset (when the RESET key on the MDI panel is pressed, the

external reset signal is applied, or the reset and rewind signal is applied),

the memorized reverse movement blocks are cleared.

D Feedrate

A feedrate for reverse movement can be specified using parameter (No.

1414). When this parameter is set to 0, the feedrate used for forward

movement is used.

For forward return movement, the feedrate for forward movement is

always used.

In reverse movement and forward return movement, the feedrate override

function, rapid traverse override function, and dry run function are

enabled.

Limitations

D Block that disables

Reverse movement stops when any of the commands or modes listed

reverse movement

below appears. If an attempt is made during forward movement to stop

forward movement with feed hold stop and then move the tool in the

reverse direction when any of the commands and modes below is

specified, the reverse movement completion state occurs.

WARNING

If an end point is not correctly placed on an arc (if a leading

line is produced) when an arc center is specified using I, J,

and K, the tool does not perform correct reverse movement.

D Interrupt-type custom

1. Never initiate an interrupt during reverse movement.

macro

2. Never perform reverse movement for an interrupte block and the

program that has issure the interrupt.

D Tool life management

The retrace function does not support the tool life management funciton.

D Switching automatic

If the operation mode is switched after a single block stop from memory

operation mode

operation to MDI operation or vice versa during reverse movement or

forward return movement, reverse movement, forward return movement,

and forward movement can no longer be performed. To restart operation,

return the mode to the original mode, then press the cycle start switch.

D Positioning (G00)

When the tool is positioned based on nonlinear interpolation by setting

bit 1 (LRP) of parameter No. 1401 to 0, the path of the tool for reverse

movement does not match the path for forward movement. The path for

forward return movement is the same as the path for forward movement.

When the tool is positioned based on linear interpolation by setting bit 1

(LRP) of parameter No. 1401 to 1, the path of the tool for reverse

movement matches the path for forward movement.

D Dwell (G04)

The dwell command (G04) is executed in reverse movement and forward

D Programmable data

A tool compensation value, parameter, pitch error data, workpiece zero

setting (G10)

point offset value, and tool life management setting specified or modified

using the programmable data setting code (G10) are ignored in reverse

movement and forward return movement.

D Stored stroke check

The on/off state of the stored stroke check function present at the end of

function on/off (G22,G23)

forward movement remains unchanged during reverse movement and

forward return movement. This means that the actual on/off state may

differ from the modal G22/G23 indication. When reverse movement or

forward return movement is cancelled upon reset, the modal G22/G23

indication at that time becomes valid.

The setting of an area with G22 X_Y_Z_I_J_K at the end of forward

movement remains unchanged.

D Skip funtion (G31),

In reverse movement and forward return movement, the skip signal and

D Chopping function

Whether the chopping operation is performed in reverse movement and

(G81.1)

forward return movement is determined by whether the chopping

operation was performed at the end of forward movement.

If the tool starts reverse movement with the chopping mode off and moves

in the reverse direction along the path of a block where the chopping mode

is on, the chopping axis maintains its position at point R.

When a block specifying G81.1 (chopping command) appears during

reverse movement, reverse movement ends and operation stops.

Along the path of a block where the tool moved according to inverse time

D Inverse time feed (G93)

feed in forward movement, the tool moves in the reverse direction

according to the feedrate specified by parameter No. 1414 (= 0) for reverse

movement.

If parameter No. 1414 for specifying the feedrate for reverse movement

is not set (= 0), the tool moves in the reverse direction at the same feedrate

as during forward movement.

D Constant surface speed

If the on/off mode of constant surface speed control is specified in reverse

control on/off (G96,G97)

movement, the specified mode is used in subsequent reverse movement.

In other words, when a block specifying G96Sxxxx; appears in reverse

movement, constant surface speed control is on for subsequent reverse

movement. When a block specifying G97Sxxxx; appears in reverse

movement, constant surface speed control is off for subsequent reverse

movement.

Note that the on/off mode of constant surface speed control in forward

movement is reversed in reverse movement.

D Clamping maximum

If the command for clamping maximum spindle speed is specified in

spindle speed

reverse movement, the specified clamp is applied to subsequent reverse

(G92Sxxxx)

movement. In other words, when G92Sxxxx appears in reverse

movement, the spindle speed is clamped at Sxxxx. Note, however, that

the spindle speed is clamped only when the G96 mode is set.

833

OPERATION

4. AUTOMATIC OPERATION

B-63534EN/02

D Auxiliary function

The M, S, and T functions, and secondary auxiliary functions (B

functions) are output directly in reverse movement and forward return

movement.

When an M, S, or T function, or secondary auxiliary function (B function)

is specified in a block containing a move command, the function and the

move command are output at the same time in forward movement, reverse

movement, and forward return movement. This means that the position

where an M, S, or T function, or secondary auxiliary function (B function)

is output differs in forward movement, reverse movement, and forward

return movement.

Even if a cutter compensation value or tool length compensation value is

D Tool compensation value

modified in reverse movement or forward return movement, the tool

moves according to the compensation value used when the block was

executed in the forward movement.

D Custom macro operation

All custom macro operations are ignored in reverse movement and

forward return movement.

The values of macro variables present at the end of forward movement

remain unchanged.

D Manual intervention

When the tool has been moved by manual intervention, return the tool to

the original position before moving the tool in the reverse direction after

a feed hold stop or single block stop.In reverse movement, the tool cannot

move along the path made during manual intervention. All movements

made by manual intervention are ignored in reverse movement and

forward return movement.

D Tool withdrawal and

The tool cannot move along the path retraction or repositioning

return function

performed using the tool withdrawal and return function. All retraction

and repositioning operations are ignored in reverse movement and

forward return movement.

D Mirror image

When a block with the mirror image function specified by a signal or

setting is memorized in forward movement, the mirror image function is

eliminated; the block is memorized as originally programmed.

Accordingly, in reverse movement and forward return movement, the tool

moves along the programmed path.In reverse movement or forward

return movement, the mirror image function can be specified by a signal

or setting.

When the tool performs reverse movement or forward return movement

for a block where the mirror image function is specified by the

programmable mirror image code (G51.1), the tool moves along the

actual path incorporating the mirror image function.

Explanations

D Manual absolute on/off

In manual absolute off mode, the tool does not return to the stop position,

but instead operates according to the manual absolute on/off function.

D Override

For the return operation, the dry run feedrate is used, and the jog feedrate

override function is enabled.

D Return operation

Return operation is performed according to positioning based on

nonlinear interpolation.

D Single block

If the single block stop switch is on during return operation, the tool stops

at the stop position and restarts movement when the cycle start switch is

pressed.

D Cancellation

If a reset occurs or an alarm is issued during manual intervention or the

return operation, this function is cancelled.

D MDI mode

This function can be used in the MDI mode as well.

Explanation

When the custom macro option is provided, both format 1 and 2 can be

used. A different M code can be used for a subprogram call depending

on the setting of parameter No. 6030. In this case, M198 is executed as

a normal M code. The file number is specified at address P. If the SBP

(bit 2) of parameter No. 3404 is set to 1, a program number can be

specified. When a file number is specified at address P, Fxxxx is indicated

instead of Oxxxx.
