Display example:
After the moment of inertia is calcu-
lated.
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
will start. While the moment of inertia is
being calculated, the set value for Pn103
will flash and “ADJ” will flash instead of
“RUN.” When calculating the moment of
inertia is completed, the display will stop
flashing and the moment of inertia is dis-
played. The servomotor will remain ON,
but the auto run operation will be stopped
temporarily.
Notes:
• The wrong key for the set travel direc-
tion is pressed, the calculation will not
start.
• If the moment of inertia is not calculated
(Jcalc = OFF), the set value for Pn103
will be displayed.
• If “NO-OP” or “Error” is displayed dur-
ing operation, press the Key to
cancel the function. Refer to (3) Failure
in Operation and take a corrective action
to enable operation.

After the servomotor is temporarily
stopped, press the
Key to save the
calculated moment of inertia ratio in the
SERVOPACK. “DONE” will flash for one
second, and “ADJ” will be displayed again.
Note: To end operation by calculating
only the moment of inertia ratio and
without adjusting the gain, press the
Key to end operation.
