11.2.4 Creating start programs for JOG operation
A PLC program must be created to execute a JOG operation. Consider the "required
control data setting", "start conditions" and "start time chart" when creating the
program.
The following shows an example when a JOG 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 PLC program, and the PLC 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.
