Description
BI: 2/3 wire control command 1 (ON/OFF1 clockwise rotation)
BI: 2/3 wire control command 2 (ON/OFF1 counter-clockwise rotation)
Example: p3331 = 722.0 ⇒ DI 0: ON/OFF1 counter-clockwise rotation
Function
0 OFF1: The motor stops.
0 ON: Clockwise motor rotation.
1 ON: Counter-clockwise motor rotation.
1 OFF1: The motor stops.
