command (R: M34483+32n/Q: M3203+20n)" turn on simultaneously for a single axis, the forward JOG operation is
executed. When a deceleration stop is made by the "[Rq.1142] Forward JOG start command (R: M34482+32n/Q:
M3202+20n)" OFF the reverse JOG operation is not executed even if the "[Rq.1143] Reverse JOG start command (R:
M34483+32n/Q: M3203+20n)" is ON. After that, when the reverse JOG start command turns off to on, the reverse JOG
operation is executed.
