Gain Adjustment
When the or Key is pressed according to
the sign (+ or -) of the value set for stroke (travel dis-
tance), the calculated value of the moment of inertia
ratio will be saved in the SERVOPACK and the auto
run operation will restart. While the servomotor is
running, the filters, and gains will be automatically
set. "ADJ" will flash during the auto setting opera-
tion.
Note: Precise adjustments cannot be made and
"Error" will be displayed as the status if there is
machine resonance when starting adjustments.
If that occurs, make adjustments using one-
parameter tuning (Fn203).

When the adjustment has been completed normally,
the servomotor power will turn OFF, and "END" will
flash for approximately two seconds and then "ADJ"
will be displayed on the status display.
10
Press the Key. The adjusted values will be saved
in the SERVOPACK.
"DONE" will flash for approximately two seconds,
and "BB" will be displayed.
Note: Press the Key to not save the values. The
display will return to that shown in step 1.
11 Turn ON the SERVOPACK power supply again after executing advanced autotuning.
