17. APPLICATION OF FUNCTIONS
17 - 36
1) Function
Vibration suppression control is used to further suppress load-side vibration, such as work-side
vibration and base shake. The servo motor-side operation is adjusted for positioning so that the
machine does not vibrate.

When the advanced vibration suppression control II ([Pr. PB02] and [Pr. PX03]) is executed, the
vibration frequency at load side is automatically estimated to suppress machine side vibration two
times at most.
In the vibration suppression control tuning mode, this mode shifts to the manual setting after the
positioning operation is performed the predetermined number of times. For manual setting, adjust
the vibration suppression control 1 with [Pr. PB19] to [Pr. PB22] and vibration suppression control
2 with [Pr. PX04] to [Pr. PX07].
2) Parameter
Set the advanced vibration suppression control II ([Pr. PB02] and [Pr. PX03]).
When you use a vibration suppression control, set "Vibration suppression control 1 tuning mode
selection" in [Pr. PB02]. When you use two vibration suppression controls, set "Vibration
suppression control 2 tuning mode selection" in [Pr. PX03] in addition.
