0 : Forward/ Stop
1 : Reverse/ Stop
2 : 3-Wire Sequence Control
The multi-function input terminal S3 to S6 can be assigned to 3-Wire Sequence Control to be
the input terminal for Forward/ Reverse Command. And terminals S1 and S2 will be
automatically assigned to Run and Stop command separately.
When terminal S1 (Run command) closes for longer than 2ms, the drive runs the motor. When
terminal S2 (Stop command) opens for even an instant, the drive stops the motor. When the
input terminal assigned to 3-wire sequence control opens, the drive runs in forward direction,
and when it is closed, the drive runs in reverse direction.
