POINT
When using the vibration suppression control
tuning mode (advanced vibration suppression
control) and the one-touch tuning simultaneously,
refer to section 7.2.4 (3).
The vibration suppression is valid when parameter No. PA08 (auto
tuning mode) is set to " 3". When PA08 is set to" 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 setting (parameter No. PB19) and vibration
suppression control resonance frequency setting (parameter No.
PB20) after positioning is performed 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 performed the predetermined number of 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 setting and vibration suppression control resonance
frequency setting. However, this does not occur when the servo off.
