8.4.3

Enable direction of rotation

In the factory setting of the inverter, the negative direction of rotation of the motor is inhibited.
Procedure
Proceed as follows to permanently enable the negative direction of rotation:
Set parameter p1110 to a value = 0.
You have permanently enabled the negative direction of rotation.
