PB02 VRFT Vibration suppression control tuning mode (Advanced vibration suppression
control)
The vibration suppression is valid when the parameter No.PA08 (auto tuning
mode) setting is "
2" or "
3". When PA08 is "
1", vibration
suppression is always invalid.
Select the setting method for vibration suppression control tuning. Setting this
parameter to "
1" (vibration suppression control tuning mode)
automatically changes the vibration suppression control vibration frequency
(parameter No.PB19) and vibration suppression control resonance frequency
(parameter No.PB20) after the predetermined number of positioning operations
are executed.

Note. Parameter No.PB19 and PB20 are fixed to the initial values.
When this parameter is set to "
1", the tuning is completed after the
predetermined number of positioning operations are executed for the
predetermined period of time, and the setting changes to "
2". When the
vibration suppression control tuning is not necessary, the setting changes to
"
0". When this parameter is set to "
0", the initial values are set to
the vibration suppression control - vibration frequency and vibration suppression
control - resonance frequency. However, this does not operate when the servo
off.

Feed forward gain
Set the feed forward gain. When the setting is 100%, the droop pulses during
operation at constant speed are nearly zero. However, sudden
acceleration/deceleration will increase the overshoot. As a guideline, when the
feed forward gain setting is 100%, set 1s or more as the acceleration time
constant up to the rated speed.
