Parameters 265
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
must be smaller
than
0.000
-1.000 … 1.000
Damping coefficient.
100 = 1
No.
