6. HOW TO USE INDEXER
(b) When [Pr. PT42] is set to 50 and [Pr. PT43] to 5 in the station JOG operation, the chart will be as
follows.
Power supply
ALM (Malfunction)
MEND (Travel completion)
PS0 (Station output 1) to
PS7 (Station output 8)
(Note 3)
Forward rotation
Servo motor speed 0 r/min
Reverse rotation
Current station position
ST1 (Forward rotation start)
MD0 (Operation mode selection 1) ON
MD1 (Operation mode selection 2)
OV0 (Digital override selection 1) to
OV3 (Digital override selection 4)
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.
