Current setpoint filters
Description
The current setpoint filters are for suppressing cyclic disturbance variables that can be
caused, for example, by mechanical vibrations in the drive train.
The current actual value filters can be set as follows:
● Low-pass 2nd order (PT2: -40 dB/decade)
● General 2nd order filter
Bandstop and low-pass with reduction are converted into the parameters of the general 2nd
order filter using STARTER.
The current actual value filters are activated with p1656.0 = 1 or p1656.1 = 1. The properties
of the current actual value filters are set in p1657 to p1666.
As long as changes to the data of the current setpoint filter are being made, the conversion
of the new filter data can be prevented using p1699 = 1.
When p1699 = 0 is set, the calculation will be performed and the new values applied.
