Inhibit direction of rotation

In the factory setting of the inverter, both motor directions of rotation are enabled.
Procedure
Proceed as follows to permanently lock a direction of rotation:
Set the corresponding parameter to a value = 1.
You have permanently locked the appropriate direction of rotation.

Minimum speed

Function
The converter prevents continuous motor operation
at speeds < minimum speed.
Speeds, where the absolute value is less than the
minimum speed, are only possible when
accelerating or braking.
