Inhibit direction of rotation

Procedure
In the factory setting of the converter, both motor directions of rotation are enabled.
If you want to permanently inhibit one of the
directions of rotation, then you must set the
corresponding parameter to 1.
With the value 0, the converter enables the
direction of rotation.

Minimum speed

Function
The inverter prevents continuous motor operation at
speeds < minimum speed.
Speeds, where the absolute value is less than the
minimum speed, can only be passed through when
accelerating or braking.
