10.4 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).

POINT
The function is made valid when the auto tuning mode (parameter No.PA08)
is the auto tuning mode 2 ("0002") or manual mode ("0003").
The machine resonance frequency supported in the vibration suppression
control tuning mode is 1.0 to 100.0Hz. The function is not effective for
vibration outside this range.
Stop the motor before changing the vibration suppression control-related
parameters (parameter No.PB02, PB19, PB20, PB33, PB34). A failure to do
so will cause a shock.
For positioning operation during execution of vibration suppression control
tuning, provide a stop time to ensure a stop after full vibration damping.
Vibration suppression control tuning may not make normal estimation if the
residual vibration at the motor side is small.
Vibration suppression control tuning sets the optimum parameter with the
currently set control gains. When the response setting is increased, set
vibration suppression control tuning again.
