1 = 1 ms / 1 = 1 msSpeed error filtering time constant. 0 = filtering disabled.0...10000 ms
Off / uint16Enables/disables resonance frequency filtering. The filtering
is configured by parameters 24.13…24.17.
The speed error value coming to the speed controller is
filtered by a common 2nd order band-elimination filter to
eliminate the amplification of mechanical resonance
frequencies.
Note: Tuning the resonance frequency filter requires a
basic understanding of frequency filters. Incorrect tuning
can amplify mechanical oscillations and damage the drive
hardware. To ensure the stability of the speed controller,
stop the drive or disable the filtering before changing the
parameter settings.
0 = Resonance frequency filtering disabled.
1 = Resonance frequency filtering enabled.

45.00 Hz / real32Defines the zero frequency of the resonance frequency
filter.
The value must be set near the resonance frequency, which
is filtered out before the speed controller.
