Three-wire control, method 2
The "Enable" command is a precondition for switching on the motor. The "ON" command
switches the motor on. The "Reversing" command inverts the motor direction of rotation.
Removing the enable switches the motor off (OFF1).

Description
p0015 = 20
Macro drive unit
You must carry out quick commissioning in order to set parameter p0015.
Assigning digital inputs DI to the commands:
DI 0: Enable / OFF1
DI 1: ON
DI 2: Reversing

Parameter
Description
p3330[0 … n] = 722.x
BI: 2/3 wire control command 1 (enable/OFF1)
p3331[0 … n] = 722.x
BI: 2/3 wire control command 2 (ON)
Example: p3331 = 722.0 ⇒ DI 0: ON command
p3332[0 … n] = 722.x
BI: 2/3 wire control command 3 (reversing)
