7 - 10
(4) Vibration suppression control manual mode
POINT
When load-side vibration does not show up in servo motor-side vibration, the
setting of the servo 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 equipment, 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 relation between the
[Pr. PB07 Model loop gain] value and vibration frequency is as follows.
Vibration suppression control 1:
[Pr. PB19] <

Vibration suppression control 2:

[Pr. PB52] < 5.0 + 0.1 × [Pr. PB07]
[Pr. PB53] < 5.0 + 0.1 × [Pr. PB07]

Measure work-side vibration and device shake with the machine analyzer or external measuring
instrument, and set the following parameters to adjust vibration suppression control manually.
