6.3.1 Advanced Autotuning

(4) Automatically Setting the Notch Filter
Usually, set this function to Auto Setting. (The notch filter is factory-set to Auto Setting.)
If this function is set to Auto Setting, vibration will be detected automatically and the notch filter will be set.
Set this function to Not Auto Setting only if you do not change the notch filter setting before executing
advanced autotuning.
Parameter
Pn460
(5) Anti-Resonance Control Adjustment Function
This function reduces vibration of which the notch filter does not effective because of low vibration frequency.
Usually, set this function to Auto Setting. (The anti-resonance control is factory-set to Auto Setting.)
When this function is set to Auto Setting, vibration will be automatically detected during advanced autotuning
and anti-resonance control will be automatically adjusted and set.
Set this function to Not Auto Setting only if you do not change the setting for anti-resonance control before
executing advanced autotuning.
For details, refer to 6.6 Anti-Resonance Control Adjustment Function (Fn204).
Pn160
The following parameters related to anti-resonance control are set automatically.
Parameter
Pn161
Pn163
Note: The following parameters related to anti-resonance control are not set automatically but the respective set values in
the parameters will apply.
Anti-resonance gain compensation (Pn162)
Anti-resonance filter time constant 1 compensation (Pn164)
Anti-resonance filter time constant 2 compensation (Pn165)
(6) Model Following Control with Vibration Suppression
The vibration suppression function suppresses transitional vibration at frequency as low as 1 to 100 Hz that is
generated mainly when positioning if the machine stand vibrates.
Usually, set this function to Auto Setting. (The vibration suppression function is factory-set to Auto Setting.)
When this function is set to Auto Setting, vibration will be automatically detected during advanced autotuning
and model following control with vibration suppression will be automatically adjusted and set.
Set this function to Not Auto Setting only if you do not change the setting for model following control with
vibration suppression before executing advanced autotuning.
Note: This function uses model following control. Therefore, the function can be executed only if the adjustment level is
set to mode 2 or 3.

• Unless the positioning completion signal (/COIN) is turned ON within approximately 3
seconds after positioning has been completed, "WAITING" will blink. Furthermore,
unless the positioning completion signal (/COIN) is turned ON within approximately 10
seconds, "Error" will blink for 2 seconds and tuning will be aborted.
