8. SPECIAL ADJUSTMENT FUNCTIONS
8.4 Advanced vibration suppression control
(1) Operation
Vibration suppression control is used to further suppress machine side vibration, such as workpiece end
vibration and base shake. The motor side operation is adjusted for positioning so that the machine does not
shake.

When the advanced vibration suppression control (vibration suppression control tuning mode (parameter
No.PB02)) is executed, the vibration frequency at machine side can automatically be estimated to suppress
machine side vibration.
In the vibration suppression control tuning mode, this mode shifts to the manual mode after positioning
operation is performed the predetermined number of times. The manual mode enables manual setting
using the vibration suppression control vibration frequency setting (parameter No.PB19) and vibration
suppression control resonance frequency setting (parameter No.PB20).
