Display example:
After the moment of inertia is
calculated.
Calculates the moment of inertia.
Press the
Key if a positive (+) value is set in
STROKE (travel distance), or press the Key if a
negative (-) value is set. Calculation of the moment of
inertia ratio will start. While the moment of inertia is
being calculated, the set value for Pn103 will blink, and
the “RUN” display will change to blinking “ADJ.”
When the calculation has been completed, the set value
will stop blinking and the calculated moment of inertia
ratio will be displayed. The servomotor power will
remain ON, but the auto run operation will enter HOLD
status.
Notes:
• The wrong key for the set travel direction is pressed,
the calculation will not start.
• If the moment of inertia is not calculated, the set
value for Pn103 will be displayed but not blink.
• If “NO-OP” or “Error” are displayed, press the
Key to cancel the function. Refer to (2) Failure in
Operation and take a corrective action to enable oper-
ation.
7
After the motor is temporarily stopped, press the
Key to save the calculated value of the moment of iner-
tia ratio in the SERVOPACK. Then, “DONE” will blink
for approx. 1 second, and “ADJ” will be displayed.
In the case of calculating the moment of inertia only,
press the
Key.

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 written to the SERVOPACK and the auto
run operation will restart. While the servomotor is run-
ning, the notch filter, the torque reference filter, and
gains will be automatically set. “ADJ” will blink during
the auto setting operation.
Note: Precise adjustments cannot be made and “Error”
will be displayed as the status if there is vibration
when starting adjustments. If that occurs, make
adjustments using one-parameter tuning (Fn203).
9
When the adjustment has been completed normally, the
servomotor power will turn OFF, and “END” will blink
for approx. 2 seconds and “ADJ” will be displayed on
the status display.
10
Press the Key. The adjusted values will be written
to the SERVOPACK, “DONE” will blink for approx. 2
seconds, and “BB” will be displayed.
Note: To not save the values, press the
Key. The
display will return to the display in step 1.
11 To enable the change in the setting, turn OFF the power and ON again.
Probable Cause Corrective Actions
The main circuit power supply was OFF. Turn ON the main circuit power supply.
An alarm or warning occurred. Remove the cause of the alarm or the warning.
Overtraveling occurred. Remove the cause of the overtravel.
Gain setting 2 was selected by gain switching. Turn OFF the automatic gain switching.
The HWBB function operated. Cancel the HWBB function.
