Damping influences the height of the harmonies and reduces the vibrations.
Nominal value: 100%
Range: 0%...500%
Harmonies become smaller. The drive vibrates at high frequency from a specific
value.
The harmonies of the actual value increase and it vibrates longer around the
nominal value. The drive vibrates permanently from a specific value.

P56: D section rpm controller
Nominal value: 0
Range: 0%...500%
The D section should generally be set for elastically coupled double mass systems.
These are systems in which the connection between the motor and the load is not
rigid. It must be noted here, that with sufficiently high torques being transmitted,
even supposedly rigid connections can become elastic.
P57: Lag D section rpm controller
Nominal value: 100%
Range: 0%...550%
P58: Lag rpm filter
Nominal value: 100%
Range: 0%...550%
Use this parameter to adapt the controller to very large changes in load.
Nominal value: 100% Range: 10%...500%
COMPAX is informed of the relative change in moment of inertia which occurs
before a change in load when the motor is idle (e.g. via the RS232 interface).
The nominal value (100%) corresponds to the value calculated by parameters P81
to P92.
After changing P27, P23 usually needs modification P23 in order to achieve
optimal control results.
