<Notes>
• For details on normal auto gain tuning function, refer to “Normal Auto Gain Tuning” on Page 132 of Adjustment
edition. Especially, please thoroughly understand the scope and cautions described in the manual to use the auto
gain tuning function.
• In the normal auto gain tuning mode the driver automatically drives the servo-motor in a predetermined operating
pattern. The operating pattern can be changed with Pr25 (normal auto tuning motion set-up), but be sure to
execute normal auto gain tuning after moving the load to the position where the motor can be driven in the
changed operating pattern without any hitch.
• Execute the normal auto gain tuning after switching on the servo.
If the connector is disconnected (during the time) by any chance, connect the connector again, and restart
the operation from the beginning.
<Remarks>
If any of the followings takes place during the tuning operation, it will cause a tuning error:
(1) During the tuning operation: 1) Any failure occurs, 2) The servo is switched off, 3) The deviation counter is
cleared, 4) The operation is made near the limit switch.
(2) The inertial or load is too heavy and the output torque is saturated.
(3) The tuning operation can not be carried out properly because some oscillation of the servo occurs.
If a tuning error occurs, value of each gain is brought back to the value that was assigned before the execu-
tion of the tuning. The tuning is not tripped except when some failure occurs. In some occasions depend-
ing on the load, oscillation of the servo may occur without indication of tuning error (“
” is not
displayed). Therefore, great attention must be given to safety of the operation.

After finishing the tuning, return to Selection Display referring to “Structure of Each Mode” (Page 48 and 49).

<Remarks>
Write the gain value
into EEPROM so that
the value may not be
lost with power off.
