8.7 Vibration suppression control filter 2
POINT
By using the advanced vibration suppression control and the vibration
suppression control filter 2, the machine side vibration of two frequencies can be
suppressed.
The frequency range of machine vibration, which can be supported by the
vibration suppression control filter 2, is between 4.5Hz and 2250Hz. Set a
frequency close to the machine vibration frequency and within the range.
When the parameter of the vibration suppression control filter 2 (parameter
No.PB45) is changed during the positioning operation, the changed setting is not
reflected. The setting is reflected approximately 150ms after the servo motor
stops (after servo lock).

(1) Operation
Vibration suppression control filter 2 has a filter function (notch filter) that lowers the gain of the specified
frequency contained in a positioning command. By lowering the gain, machine side vibration, such as
workpiece end vibration and base shake, can be suppressed.
Which frequency to lower the gain and how deep to lower the gain can be set.
