5.2 JOG Operation
Creating start programs for JOG operation
A 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 "100.00 mm/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 program.
n: Axis No. - 1
Refer to the followings for the setting details.

Start conditions
The following conditions must be fulfilled when starting. The required conditions must also be assembled in the program, and
the program must be configured so the operation will not start if the conditions are not fulfilled.
*1 The interlock must be provided so that the buffer memory is accessed after Synchronization flag [X1] turns on. When no interlock is
provided, an unexpected value may be read or written.
