7.3 Vibration suppression control manual mode
Measure work side vibration and device shake with the machine analyzer or external measuring instrument, and
set the vibration suppression control vibration frequency (parameter No.PB19) and vibration suppression control
resonance frequency (parameter No.PB20) to set vibration suppression control manually.
(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.
