Remedy For Insufficient Adaptation; Function Diagrams And Parameters - Siemens SINAMICS S120 Function Manual

For the case that one of the limit frequency parameters (p5282 or p5283) is written and the
current blocking frequency of the band-stop filter is beyond the relevant new limit frequency, the
following applies:
● If the adaptation is active, the band-stop filter is automatically set to the relevant limit
frequency when p5282 or p5283 is written.
● If the adaptation is not active, the band-stop filter is automatically set to the relevant limit
frequency when the adaptation is activated.

Remedy for insufficient adaptation

If the adaptation does not change the blocking frequency of the adapted current setpoint filter
during operation, then the mechanical resonant frequency is not sufficiently excited and
therefore has no negative effect on the operation. If you nevertheless want to change the
behavior of the adaptation, the following options are available:
● Change the activation threshold (p5284).
● Change the blocking frequency in the relevant filter parameters in order to obtain a different
start value for the adaptation.
● Increase the speed controller gain via p1460 or p5272 to further excite the mechanical
resonant frequency. However, observe the stability of the control loop with this setting.
