Signal

Position record signal PRC <Gn040.6>

[Classification] Input signal

[Function] This signal is prepared for the function of direct input of tool offset value measured or

direct input of coordinate system shift.

It is used to store the data on the positions of the tool for tentative cutting in the control

unit. After measuring the workpiece position, input the measured value by the specified

manual operation. The difference of the coordinate system actually set and the workpiece

coordinate system assumed at programming is set in the workpiece coordinate system

shift value.

[Operation] The control unit stores the current position along X and Z axes when the signal turns to

"1".

CAUTION

To use this signal, set bit 2 (PRC) of parameter No.5005 to 1.

Each axis workpiece coordinate system preset signals

Overview

The each axis workpiece coordinate system preset signals are function for presetting a workpiece

coordinate system shifted due to manual intervention, a machine lock, etc. to a workpiece coordinate

system offset from the pre-shift machine zero point by a workpiece origin offset value, using an input

signal.

Each axis workpiece coordinate system preset signals become effective by setting bit 6 (WPS) of

parameter No. 3006 to 1.

If actual tool length offset need to be considered when workpiece coordinate system preset is done, bit 7

(WTC) of parameter No. 1205 need to be set to 1.

Signal

Each axis workpiece coordinate system preset signals

WPRST1 to WPRST8 <Gn358>

[Classification] Input signal

[Function] These signals are used to preset a workpiece coordinate system shifted due to manual

intervention, a machine lock, etc.

[Operation] By changing the signal for the axis for which to perform a workpiece coordinate system

preset from “0” to “1”, the workpiece coordinate system preset is performed. This cancels

the shift amount for the workpiece coordinate system that is due to any of the items below,

so that the workpiece coordinate system can be preset to a workpiece coordinate system

preset from the pre-shift machine zero point by the workpiece origin offset value.

(a) Manual intervention performed when the manual absolute signal is off

(b) Move command executed in the machine lock state

(d) Operation using the mirror image function

(e) Setting of a local coordinate system with G52 or shift of a workpiece coordinate

system with G92/G50 (for the T series)

NOTE

1 If performing workpiece coordinate system preset with an each axis

workpiece coordinate system preset signal during automatic

operation, specify it with the M code set in parameters Nos. 11275

and 11276 or perform it during a single block stop.

2 If preset is to be performed with an each axis workpiece coordinate

system preset signal during automatic operation, the state must be

that in which all axes on the path including the axis on which to

perform each axis workpiece coordinate system preset are stopped

and no commands are in execution. If not all axes are stopped or if

a command is in execution, alarm PS1820, “ILLEGAL DI SIGNAL

STATE” is issued.

NOTE

3 When an M code for performing each axis workpiece coordinate

system preset is issued during automatic operation, if the

corresponding each axis workpiece coordinate system preset signal

is not set to 1, alarm PS1820 is issued. It is possible to suppress the

alarm by setting bit 0 (WPA) of parameter No. 11277 to 1. In this

case, axis workpiece coordinate system preset is not performed.

4 During a reset (RST<Fn001.1> = “1”), preset with an each axis

workpiece coordinate system preset signal is disabled. Preset is

performed at the point the reset is canceled.

5 During an auxiliary function lock, this function is disabled.

6 In general, if preset is to be performed with an each axis workpiece

coordinate system preset signal, the state must be that in which all

axes on the path including the axis on which to perform each axis

workpiece coordinate system preset are stopped. However, when

bit 1 (EAX) of parameter No. 10410 is set to 1 and the axis moves

by the PMC axis control, it is possible to exclude the axis from this

condition. That is, the preset can be performed without stopping the

axis that moves by the PMC axis control. However, when you move

the axis that moved by the PMC axis control by the NC commands,

it is necessary to stop the axis, and to reflect the amount of

movement by PMC axis control to the program coordinate system

by the manual return to the reference position etc.

7 Be sure to specify an M code used to turn on each axis workpiece

coordinate system preset signal in an independent block.

Each axis workpiece coordinate system preset completion signals

WPSF1 to WPSF8<Fn358>

[Classification] Output signal

[Function] These signals notify the PMC of the each axis workpiece coordinate system preset status.

[Output cond.] These signals become “1” in the following case:

When workpiece coordinate system preset is completed with the corresponding each

axis workpiece coordinate system preset signals.

They become “0” in the following cases:

When the corresponding each axis workpiece coordinate system preset signals

change from “1” to “0”.

When a reset is performed.

When workpiece coordinate system preset is done, actual tool length offset is:

0: Not considered.

1: Considered.

When this parameter is set 1, it is possible to preset the workpiece coordinate system by

G-code, MDI operation or the workpiece coordinate system preset signal without

canceling the tool length compensation modes.

The compensation vector is kept as the below figure when the workpiece coordinate

system preset is done to the coordinate shifted by amount of movement during manual

intervention.

1. An each axis workpiece coordinate system preset signal was turned on

in the state in which all axes on the path including the axis on which to
perform preset with the each axis workpiece coordinate system were
not stopped or in which a command was in execution.

2. When an M code for performing preset with an each axis workpiece

coordinate system preset signal was specified, the each axis workpiece
coordinate system preset signal was not turned on.

3. The auxiliary function lock is enabled.
4. When bit 6 (PGS) of parameter No. 3001 was set to 0 (M, S, T, and B

codes are not output in the high speed program check mode), an M
code for turning on an each axis workpiece coordinate system preset
signal in the high speed program check mode was specified.

Notes

NOTE

The limitations are the same as those for the workpiece coordinate system preset

using a program command (G92.1 or G50.3 (for G code system A (T series) or

using MDI operation. Thus, before performing preset with this function, cancel

each compensation mode (cutter compensation, tool offset, and tool length

compensation). Otherwise, the compensation vector will be canceled. If this

occurs, specify each compensation mode again. For details, refer to the

OPERATOR’S MANUAL (Common to Lathe System/Machining Center System)

(B-64694 EN).

Local Coordinate System

Overview

When a program is created in a workpiece coordinate system, a child workpiece coordinate system can be

set for easier programming. Such a child coordinate system is referred to as a local coordinate system.

Format

G52

_; Setting the local coordinate system

:
G52

0 ; Canceling the local coordinate system

_ : Origin of the local coordinate system

Explanation

By specifying G52 IP_;, a local coordinate system can be set in all the workpiece coordinate systems

(G54 to G59). The origin of each local coordinate system is set at the position specified by IP_ in the

workpiece coordinate system.

Once a local coordinate system is established, the coordinates in the local coordinate system are used in

an axis shift command. The local coordinate system can be changed by specifying the G52 command with

the zero point of a new local coordinate system in the workpiece coordinate system.

To cancel the local coordinate system and specify the coordinate value in the workpiece coordinate

system, match the zero point of the local coordinate system with that of the workpiece coordinate system.
