8. SPECIAL ADJUSTMENT FUNCTIONS
You can use the machine resonance suppression filter 1 (parameter No.58) and machine resonance
suppression filter 2 (parameter No.59) to suppress the vibration of two resonance frequencies. Note that if
adaptive vibration suppression control is made valid, the machine resonance suppression filter 1
(parameter No.58) is made invalid.

POINT
The machine resonance suppression filter is a delay factor for the servo
system. Hence, vibration may increase if you set a wrong resonance frequency
or a too deep notch.
(2) Parameters
(a) Machine resonance suppression filter 1 (parameter No.58)
Set the notch frequency and notch depth of the machine resonance suppression filter 1 (parameter
No.58)
When you have made adaptive vibration suppression control selection (parameter No.60) "valid" or
"held", make the machine resonance suppression filter 1 invalid (parameter No.58: 0000).
