6. GENERAL GAIN ADJUSTMENT
6.2.4 Response level setting in auto tuning mode
Set the response (The first digit of parameter No.PA09) of the whole servo system. As the response level
setting is increased, the track ability and settling time for a command decreases, but a too high response level
will 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, filter tuning mode (parameter No.PB01) or machine resonance suppression filter (parameter
No.PB13 to PB16) may be used to suppress machine resonance. Suppressing machine resonance may allow
the response level setting to increase. Refer to section 7.3 for filter tuning mode and machine resonance
suppression filter.
