10.4.1 Sample Program (JOG Operation)
The operation for starting the JOG operation is mainly divided into five steps on a user
program.
• Read flags stored in the unit memories (input control area).
• Control the Servo ON/OFF.
• Check the state if the control of each axis can be started.
• Set the condition for the JOG operation (option), confirm the required start condition and
start the JOG operation.
• Write operation results in the unit memories (output control area).
(Note): The sample program on the next page is for activating the JOG operation of the axis number 1 for FP7 MC
Unit installed in the slot number 1. To simplify the explanation, the part related to the JOG operation is extracted.

KEY POINTS
•
In the case of "JOG operation (Infinite rotation)", the unit operates by the
level signals of "JOG forward/reverse request".
•
The "JOG inching operation" starts at the leading edge of the "JOG
forward/reverse request".
•
It is possible to switch between "JOG operation (Infinite rotation)" and "JOG
inching operation" by turning ON/OFF the corresponding bit to the "JOG
inching operation request" area in the unit memories.
