Commands "ON/OFF1 clockwise rotation" and "ON/OFF1 counter-clockwise rotation" switch
on the motor - and simultaneously select a direction of rotation. The inverter only accepts a
new command when the motor is at a standstill.

Parameter
Description
p0015 = 12
Macro drive unit
You must carry out quick commissioning in order to set parameter p0015.
Assigning digital inputs DI to the commands:
DI 0: ON/OFF1 clockwise rotation
DI 1: ON/OFF1 counter-clockwise rotation

Parameter
Description
p3330[0 … n] = 722.x
BI: 2/3 wire control command 1 (ON/OFF1 clockwise rotation)
p3331[0 … n] = 722.x
BI: 2/3 wire control command 2 (ON/OFF1 counter-clockwise rotation)
Example: p3331 = 722.0 ⇒ DI 0: ON/OFF1 counter-clockwise rotation
