Suppression bandwidths and setpoint limits

In the range 0 U/min to setpoint speed, a drive train (e.g. motor, coupling, shaft, machine)

can have one or more points of resonance, which can result in vibrations. The suppression

bandwidths can be used to prevent operation in the resonance frequency range.

The limit frequencies can be set via p1080[D] and p1082[D]. These limits can also be

changed during operation with the connectors p1085[C] and p1088[C].
