5.4.1.3 Set current setpoint filter (band-stop filter)

Due to the high dynamic performance or the high limit frequency of the closed current control loop,

mechanical natural frequencies can be excited, which can result in resonance and thus cause the

speed control loop to become unstable.

In order to suppress or damp these resonant frequencies, two current setpoint filters are integrated

in the speed control loop of the controller, which need to be parameterised. In the Lenze setting,

these filters are switched off:
