11.3.4 Creating a program to enable/disable the inching operation
A sequence program must be created to execute an inching operation. Consider the
"required control data setting", "start conditions", and "start time chart" when creating
the program.
The following shows an example when an inching operation is started for axis 1. (The
example shows the inching operation when a "10.0 µm" is set in "
Cd.16
Inching
movement amount".)
Required control data setting
The control data shown below must be set to execute an inching operation. The
setting is carried out with the sequence program.

Set the setting value so that the command
pulse is not increased larger than the maximum
output pulse.

QD75D N: 4Mpps
QD75D : 1Mpps
QD75P N/QD75P : 200kpps)

Refer to Section 5.7 "List of control data" for information on setting details.
Start conditions
The following conditions must be fulfilled when starting. The required conditions
must also be assembled in the sequence program, and the sequence program
must be configured so the operation will not start if the conditions are not fulfilled.

If the CPU module is set to the asynchronous mode in the synchronization setting, this must be
inserted in the program for interlocking. If it is set to the synchronous mode, it must not be
inserted in the program for interlocking because it is turned ON when the CPU module executes
calculation.
