Chapter 11 Manual Control
11.4.4 Creating a program to enable/disable the manual pulse generator operation
A sequence program must be created to execute a manual pulse generator operation.
Consider the "required control data setting", "start conditions" and "start time chart"
when creating the program.
The following shows an example when a manual pulse generator operation is started
for axis 1.

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 PLC CPU 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 PLC CPU executes
calculation.
