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-
resis.
The suppression speeds apply in the positive and
negative direction of rotation.
