9. SPECIAL ADJUSTMENT FUNCTIONS

You can use the machine resonance suppression filter 1 (parameter No. 61) and machine resonance suppression filter 2 (parameter No. 62) 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. 61) 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. 61)

Set the notch frequency and notch depth of the machine resonance suppression filter 1 (parameter No. 61)

When you have made adaptive vibration suppression control selection (parameter No. 63) "valid" or "held", make the machine resonance suppression filter 1 invalid (parameter No. 61: 0000).
