2 : 3-Wire Sequence Control
The multi-function input terminal S3 to S7 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.

Note:
1. When entering a Run command, close the terminal for minimum 2 ms.
2. If the Run command is active at power up and b1-10 (Run Command at Power up)= 0 (Ignore), the protection will
be triggered and LED indicator will flash. Set b1-10 (Run Command at Power up)=1 (Accept) to accept an active Run
command at power up.
WARNING!
Safety during Machinery Restart
·
Make sure wiring for Run/ Stop and safety circuits are correct and check if the machinery is normal after
applying power to the drive. Improper wiring could cause inquiry due to machinery sudden movement. When
setting 3-wire sequence control, the drive could suddenly start running due to the control circuit momentarily
close.
