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)
Using parameter No. 58, set the notch frequency and notch depth of the machine resonance
suppression filter 1.
When you have made adaptive vibration suppression control selection valid or held in parameter
No. 60, set "0000" to make the machine resonance suppression filter 1 invalid.
