11.2.4 Creating start programs for JOG operation
A sequence 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.
("
Cd.17
JOG speed" is set to "100.00mm/min" in the example shown.)
Required control data setting

1 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.

If the operation is stopped by the limit switch "OFF", JOG operation can be carried out in the
direction in which the limit switch turns ON.
