1) Turn on the Motor servo by the input SVON (Servo on).
2) The output SVST (Servo state) closes when the Motor servo is on.
3) Set the jogging direction by the input DIR (Jog direction).
4) Activates the input JOG (Jog).
The Motor starts a motion following the parameter value of JA (Jog acceleration), JB
(Jog deceleration) and JV (Jog velocity).
5) The output BUSY (In-operation) closes when the Motor is jogging and the output IPOS (In-
position) opens.
6) When the input DIR is altered in the middle of jogging, the Motor decelerates and stops, then
the Motor starts in the specified direction.
7) The Motor starts to decelerate when the input JOG is turned OFF.
8) The output BUSY opens at the completion of inputting the internal command for deceleration.
The output IPOS remains open at this time because the jogging started from the position at
where the former positioning operation had completed.
 Different from the positioning operation, the output IPOS does not signal the completion of jogging.
Confirm the completion of jogging by the output BUSY.
