Current Setpoint Filter - Siemens SINAMICS S120 Function Manual

Current setpoint filter

Description
The two current setpoint filters connected in series can be parameterized as
follows:
S Low-pass 2nd order (PT2): –40dB/decade)
S General filter 2nd order
Band-stop and low-pass with reduction are converted to the parameters of the
general filter 2nd order via STARTER.
– Bandstop
– Low-pass with reduction by a constant value
The phase frequency curve is shown alongside the amplitude log frequency curve.
A phase shift results in a control system delay and should be kept to a minimum.
