8. SPECIAL ADJUSTMENT FUNCTIONS
POINT
When machine end vibration does not show up in motor end vibration, the
setting of the motor end vibration frequency does not produce an effect.
When the anti-resonance frequency and resonance frequency can be confirmed
using the machine analyzer or external FFT device, 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.
