7.2.4 Response level setting in auto tuning mode

Set the response (The first digit of parameter No.2) 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 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, adaptive vibration suppression control (parameter No. 60) or machine resonance
suppression filter (parameter No. 58 59) may be used to suppress machine resonance. Suppressing
machine resonance may allow the response level setting to increase. Refer to Section 8.1 for adaptive
vibration suppression control and machine resonance suppression filter.
