: 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.
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
The control data shown below must be set to execute a JOG operation. The
setting is carried out with the sequence program.
Setting
value
0 Set "0".
Set a value equal to or below the "[Pr.31]
10000
JOG speed limit value".
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.
