NOTE

1)OFF indicates normally open and ON indicates normally closed.

2)When speed control mode is Sz, the speed command S1=0; when speed control mode is S, the speed command S1 is external analog voltage input (Please refer to P1-01).

3)After Servo ON, the users can select command according to the state of SPD0~1.
