POINT
When machine side vibration does not show up in motor side vibration, the setting
of the motor side vibration frequency does not produce an effect.
When the anti-resonance frequency and resonance frequency can be confirmed
using the machine analyzer or external measuring instrument, do not set the same
value but set different values to improve the vibration suppression performance.
A vibration suppression control effect is not produced if the relationship between the
model loop gain (parameter No.PB07) value and vibration frequency is as indicated
below. Make setting after decreasing PG1, e.g. reduce the response setting.
