Creating A Start Program For The Jog Operation - Mitsubishi Electric MELSEC iQ-R-RD75P4 User Manual

Creating a start program for the JOG operation

To perform the JOG operation, create a program. When creating a program, consider Control data requiring settings, Start
condition, and Start time chart. The following shows an example when the JOG operation is started for the axis 1. ([Cd.17]
JOG speed is set to 100.00mm/min.)
Control data requiring settings
The following control data must be set to execute the JOG operation. The setting is executed with a program.
Setting item
[Cd.16] Inching movement amount
[Cd.17] JOG speed
For details on the settings, refer to the following.

Start condition
Satisfy the following conditions to start a program. In addition, set the required conditions in the program to prevent an
operation from starting if the conditions are not satisfied.

*1 The interlock must be provided so that the buffer memory is accessed after Module access flag [X1] turns on. When no interlock is
provided, the buffer memory may be accessed while the module parameter and module extension parameter that are sent from the CPU
module are updated. If the buffer memory is accessed during the update, an unexpected value may be read or written.
