Confirm that the follow-
ing condition is met:
1/4 ≤ (Servomotor
capacity/SERVOPACK

Replace the encoder
and check to see if the

Correction
Make sure that the setting
of the Fully-closed Mod-
ule agrees with the setting
of Pn002 = n.X.
Change the number of
bytes for bank members
to an appropriate value.
Reduce the total amount
of bank data to 64 or less.
Select a proper combina-
tion of the SERVOPACK
and Servomotor capaci-
ties.
Replace the Servomotor
or encoder.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
Change to a correct com-
bination of models.
Turn the power supply to
the SERVOPACK OFF and
ON again. Or, execute a
software reset.
