Skip frequency bands

The inverter prevents continuous motor operation

at speeds in the suppression-speed range.

This can prevent speeds from being approached

stationary that, for example, cause excitation of

resonancy vibrations of the drive train.

To ensure that the speed does not constantly

increase and decrease in the suppression band-

width (speeds), the bands are assigned a hyste-

The suppression speeds apply in the positive and

negative direction of rotation.
