9. SPECIAL ADJUSTMENT FUNCTIONS

POINT

If the frequency of machine resonance is unknown, decrease the notch frequency from higher to lower ones in order. The optimum notch frequency is set at the point where vibration is minimal.

A deeper notch has a higher effect on machine resonance suppression but increases a phase delay and may increase vibration.

The machine characteristic can be grasped beforehand by the machine analyzer on the servo configuration software. This allows the required notch frequency and depth to be determined.

Resonance may occur if parameter No. 61 62 is used to select a close notch frequency and set a deep notch.

(b)Machine resonance suppression filter 2 (parameter No. 62)

The setting method of machine resonance suppression filter 2 (parameter No. 62) is the same as that of machine resonance suppression filter 1 (parameter No. 61). However, the machine resonance suppression filter 2 can be set independently of whether adaptive vibration suppression control is valid or invalid.

9.3Adaptive vibration suppression control

(1)Function

Adaptive vibration suppression control is a function in which the servo amplifier detects machine resonance and sets the filter characteristics automatically to suppress mechanical system vibration. Since the filter characteristics (frequency, depth) are set automatically, you need not be conscious of the resonance frequency of a mechanical system. Also, while adaptive vibration suppression control is valid, the servo amplifier always detects machine resonance, and if the resonance frequency changes, it changes the filter characteristics in response to that frequency.

POINT

The machine resonance frequency which adaptive vibration suppression control can respond to is about 150 to 500Hz. Adaptive vibration suppression control has no effect on the resonance frequency outside this range. Use the machine resonance suppression filter for the machine resonance of such frequency.

Adaptive vibration suppression control may provide no effect on a mechanical system which has complex resonance characteristics or which has too large resonance.

Under operating conditions in which sudden disturbance torque is imposed during operation, the detection of the resonance frequency may malfunction temporarily, causing machine vibration. In such a case, set adaptive

vibration suppression control to be "held" (parameter No. 63: 2 ) to fix the characteristics of the adaptive vibration suppression control filter.
