Display example:
After the mass is calculated.
Calculates the mass.
Press the Key if a positive (+) value is set in
STROKE (travel distance), or press the Key if a
negative (-) value is set. Calculatio
n of the mass will
start. While the mass is being calculated, the set value
for Pn103 will flash and “ADJ” will flash instead of
“RUN.” When calculating the mass is completed, the
display will stop flashing and the mass is displayed.
The servomotor will remain ON, but the auto run
operation will be stopped temporarily.
Notes:
• The wrong key for the set travel direction is
pr
essed, the calculation will not start.
• If the mass is not calculated (Jcalc = OFF), the set
value fo
r Pn103 will be displayed.
• If "NO-OP" or "Error" is displayed during opera-
tion, press the Key to cancel the function.
Refer to (2) Failure in Operation and take a cor-
rective action to enable operation.

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

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 mass ratio will be
saved in the SERVOPACK and the auto run operation
will restart. While the servomotor is running, the fil-
ters, and gains will be automatically set. "ADJ" will
flash
during the auto setting operation.
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.
