Commands "ON/OFF1 clockwise rotation" and "ON/OFF1 counter-clockwise rotation" switch
on the motor - and simultaneously select a direction of rotation. The inverter accepts a new
command at any time, independent of the motor speed.

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
