–Setup of an action
at normal mode
auto-gain tuning
You can set up the action pattern at the normal mode auto-gain tuning.
e.g.) When the setup is 0, the motor turns 2 revolutions to CCW and 2
revolutions to CW.

–Setup of
instantaneous
speed observer
With a high stiffness machine, you can achieve both high response and
reduction of vibration at stall, by using this instantaneous speed observer.

Valid
You need to set up the inertia ratio of Pr20 correctly to use this function.
If you set up Pr21, real-time auto-gain tuning mode setup, to other than 0 (valid), Pr27 becomes 0 (invalid)

–Setup of adaptive
filter mode
You can set up the action of the adaptive filter.
0 : Invalid
1 : Valid
2 : Hold
(holds the adaptive filter frequency when this setup is changed to 2.)
<Caution>
When you set up the adaptive filter to invalid, the adaptive filter frequency
of Pr2F will be reset to 0. The adaptive filter is always invalid at the
torque control mode.

–Selection of
machine stiffness
at real-time
auto-gain tuning
You can set up the machine stiffness in 16 steps while the real-time auto-
gain tuning is valid.
<Caution>
When you change the setup value rapidly, the gain changes rapidly as
well, and this may give impact to the machine. Increase the setup
gradually watching the movement of the machine.

–Selection of
2nd notch depth
You can set up the 2nd notch depth of the resonance suppressing filter. Higher
the setup, shallower the notch depth and smaller the phase delay you can obtain.

You can set up the 2nd notch width of the resonance suppressing filter in
5 steps. The notch filter function is invalidated by setting up this parame-
ter to "1500".

–Selection of
2nd notch width
You can set up the notch width of 2nd resonance suppressing filter in 5
steps. Higher the setup, larger the notch width you can obtain.
Use with default setup in normal operation.
<Notes>
• Parameters which default values have a suffix of "*" will be automatically set up during real time auto-gain
tuning. When you change manually, invalidate the real-time auto-gain tuning first then set, referring to
P.239, "Release of Automatic Gain Adjusting Function" of Adjustment.
