- Usage

When the command of M02 or M30 is executed, the total number of
machined parts and the number of machined parts are incremented by
one. Therefore, create the program so that M02 or M30 is executed
every time the processing of one part is completed. Furthermore, if an
M code set to the parameter No. 6710 is executed, counting is made in
the similar manner. Also, it is possible to disable counting even if
M02 or M30 is executed (bit 0 (PCM) of parameter No. 6700 is set to
1). For details, see the manual issued by machine tool builders.

Limitation
- Run time and part count settings

Negative value cannot be set. Also, the setting of "M" and "S" of run
time is valid from 0 to 59.
Negative value may not be set to the total number of machined parts.

- Time settings

Neither negative value nor the value exceeding the value in the
following table can be set.

Displaying and Setting the Workpiece Origin Offset Value

(15-inch Display Unit)

Displays the workpiece origin offset for each workpiece coordinate
system (G54 to G59, G54.1 P1 to G54.1 P48 and G54.1 P1 to G54.1
P300) and external workpiece origin offset.
The workpiece origin offset value and external workpiece origin offset
value can be set on this screen.

Procedure for displaying and setting the workpiece origin offset value

Procedure

Press function key

Press vertical soft key [WORK].
The workpiece coordinate system setting screen is displayed.

Fig. 12.3.19 (a) WORK COORDINATES screen (15-inch)

3 The screen for displaying the workpiece origin offset values

consists of two or more pages.

Display a desired page in either of the following two ways:

•

Press the page key

•

Enter the workpiece coordinate system number (0 : external
workpiece origin offset, 1 to 6: workpiece coordinate
systems G54 to G59, P1 to P48 : workpiece coordinate
systems G54.1 P1 to G54.1 P48, P1 to P300 : workpiece
coordinate systems G54.1 P1 to G54.1 P300) and press
horizontal soft key [NO.SRH].

Turn off the data protection key to enable writing.

Move the cursor to the workpiece origin offset to be changed.

horizontal soft key [INPUT]. The entered value is specified in the
workpiece origin offset value. Or, by entering a desired value
with numeric keys and pressing horizontal soft key [+INPUT],
the entered value can be added to the previous offset value.

Repeat steps 5 and 6 to change other offset values.

Turn on the data protection key to disable writing.

Direct Input of Workpiece Origin Offset Value Measured

(15-inch Display Unit)

This function is used to compensate for the difference between the
programmed workpiece coordinate system and the actual workpiece
coordinate system. The measured offset for the origin of the
workpiece coordinate system can be input on the screen such that the
command values match the actual dimensions.
Selecting the new coordinate system matches the programmed
coordinate system with the actual coordinate system.

Position the cursor to the workpiece origin offset value to be set.

Press the address key for the axis along which the offset is to be
set (Y-axis in this example).

8 Enter the measured value (

) then press horizontal soft key

[MEASUR].

Move the reference tool manually until it touches surface B of
the workpiece.

10 Retract the tool without changing the X coordinate.
11 Enter the measured value of distance (

) to surface B as an X

value as with steps 7 and 8.

Limitation
- Consecutive input

Offsets for two or more axes cannot be input at the same time.

- During program execution

This function cannot be used while a program is being executed.

Displaying and Setting Real Time Custom Macro Data

(15-inch Display Unit)

Real time macro variables (RTM variables) are dedicated to real time
custom macros.
RTM variables are divided into temporary real time macro variables
(temporary RTM variables) and permanent real time macro variables
(permanent RTM variables).
The values of permanent RTM variables are kept stored after the
power is turned off.
Temporary RTM variables are cleared to 0 when the power is turned
off.

System variables (DI/DO variables) dedicated to real time custom
macros are used to read and write PMC interface signals. Data can be
read and written in bit and byte units. Before writing a signal, release
the protection of the corresponding variable on the PMC signal protect
screen.

Procedure

Press function key

2 Press vertical soft key [NEXT PAGE] several times and then

vertical soft key [R.TIME MACRO]. The screen shown below
appears.
