3.7Current setpoint filter

Description

The four current setpoint filters connected in series can be parameterized as follows:

●Low-pass 2nd order (PT2: -40 dB/decade) (type 1)

●General filter 2nd order (type 2)

Bandstop and lowpass 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.
