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.
The setting range of [Pr. PB19], [Pr. PB20], [Pr. PX04], and [Pr. PX05] varies,
depending on the value in [Pr. PB07]. If a value out of the range is set, the
vibration suppression control will be disabled.
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.

Step 1. Select "Manual setting (_ _ _ 2)" of "Vibration suppression control 1 tuning mode
selection" in [Pr. PB02] or "Manual setting (_ _ 2 _)" of "Vibration suppression control 2
tuning mode selection" in [Pr. PX03].
Step 2. Set "Vibration suppression control - Vibration frequency" and "Vibration suppression
control - Resonance frequency" as follows.
However, the value of [Pr. PB07 Model loop gain], vibration frequency, and resonance frequency
have the following usable range and recommended range.
