Figure 6-7
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.

Description
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
Changing the assignment of the digital inputs
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 ON: The motor direction of rotation is defined
by the command that first reaches state "1".
