Home position return is in progress.
(b) When [Pr. PT42] is set to 50 and [Pr. PT43] to 5 in the station JOG operation, the chart will be as
follows.

Note 1. In the manual operation mode, when turning on/off ST1 (Forward rotation start) with 0% digital override and change the digital
override to other than 0%, the shaft will stop at the closest station regardless of ST1 (Forward rotation start) off.
2. Changing the digital override to 0% during operation will decelerate to a stop. Then, the digital override is changed to 0%, JOG
operation will start again. In that case, the shaft stops at the closest station regardless of ST1 (Forward rotation start) off.
3. For MR-J4-03A6-RJ servo amplifiers, up to six points of DO are available; therefore, PS0 to PS7 cannot be outputted
simultaneously.
