Parameter Description
p0015 = 18 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
Table 6-17 Changing the assignment of the digital inputs
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
Advanced commissioning
