6. GENERAL GAIN ADJUSTMENT
6.2.4 Response level setting in auto tuning mode
Set the response (parameter No.9) of the whole servo system. As the response level setting is increased,
the trackability and settling time for a command decreases, but a too high response level w ill generate
vibration. Hence, make setting until desired response is obtained within the vibration-free range.
If the response level setting cannot be increased up to the desired response because of machine resonance
beyond 100Hz, adaptive vibration suppression control (parameter No.25) or machine resonance
suppression filter (parameter No. 18) may be used to suppress machine resonance. Suppressing machine
resonance may allow the response level setting to incre ase. Refer to Section 7.2, 7.3 for adapt ive v i bra t ion
suppression control and machine resonance suppression filter.
