The optimum notch filter frequen-
cies (Pn408, Pn409, and Pn40C)
are automatically changed accord-
ing to the resonance frequencies
and the values are saved in the
SERVOPACK.
If the first notch filter has already
been set, the second notch filter
value is set. If the first and second
notch filters have already been set,
the filter values are not changed.
Note: Pn408 = n.1 (Use first stage
notch filter),
Pn409 = 1375[Hz] (First Stage
Notch Filter Frequency)
Pn408 = n.1 (Use second
stage notch filter),
Pn40C = 1375[Hz] (Second Stage
Notch Filter Frequency)
