228 Parameters
Defines 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.
The drawing shows the frequency response.
45.00 Hz
0.50 … 500.00 Hz
Zero frequency.
1 = 1 Hz
Defines the damping coefficient for parameter
. The
value of 0 corresponds to the maximum elimination of the
resonance frequency.
Note:
To ensure that the resonance frequency band is filtered
(rather than amplified), the value of
.
0.000
-1.000 … 1.000
Damping coefficient.
100 = 1
No.
