PB02 VRFT Vibration suppression control tuning mode (advanced vibration
suppression control)
The vibration suppression is valid when the parameter No. PA08
(auto tuning) 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 positioning is done the predetermined number of times.

Note. Parameter No. PB19 and PB20 are fixed to the initial
values.
When this parameter is set to "
1", the tuning is completed
after positioning is done the predetermined number or times 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 occur when the servo off.
