Advanced vibration suppression control precautions

• When changing the servo parameters related to the vibration suppression control, stop the servo motor first. Otherwise, it
will cause an unexpected movement of the servo motor or the other part in the system.
• Vibration suppression control tuning is unable to be estimated normally if the residual vibration at the servo motor side is
small.

Advanced vibration suppression control setting method

Set [Pr. PB02 Vibration suppression control tuning mode (advanced vibration suppression control II)]. When using one
vibration suppression control, set [Pr. PB02.0 Vibration suppression control 1 - Tuning mode selection] to "1" (automatic
setting). When using two vibration suppression controls, set [Pr. PA24 Vibration suppression mode] to "1" (3 inertia mode),
[Pr. PB02.0] to "1" (automatic setting), and [Pr. PB02.1 Vibration suppression control 2 - Tuning mode selection] to "1"
(automatic setting).
Set [Pr. PA24] to "1" (3 inertia mode), [Pr. PB02.0] to "1" (automatic setting), and [Pr. PB02.1] to "1" (automatic setting) as a
standard. If using one vibration suppression control is assessed to be optimal inside the servo amplifier, only vibration
suppression control 1 or vibration suppression control 2 automatically becomes enabled.

Advanced vibration suppression control adjustment method

• When load-side vibration is not transferred to the servo motor-side, setting the servo motor-side vibration
frequency is not effective. In addition, vibration suppression control tuning may fail to accurately set the
vibration frequency automatically.
• When the anti-resonance frequency and resonance frequency can be checked using the machine analyzer
or external equipment, set different values (do not set the same value) to improve the vibration suppression
performance.
The following is a flowchart of vibration suppression control 1. When using Vibration suppression control 2, set [Pr. PB02.1
Vibration suppression control 2 tuning mode] to "1" (automatic setting), and execute Vibration suppression control tuning.
