•
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.
