detection conditions
are satisfied.
Check to see if the

Check the capacities to
see if they satisfy the
following condition:
Servomotor capacity
≤ ≤
1/4
SERVOPACK capacity
Replace the encoder
and check to see if the
alarm still occurs.

Check to see if the
motor parameter file
was written to the lin-
ear encoder.
Check the product

Continued from previous page.
Correction
Decrease the setting of
the electronic gear ratio
(Pn20E/Pn210).
Increase the setting of
Pn533 or Pn585.
Decrease the setting of
the electronic gear ratio
(Pn20E/Pn210).
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-
4
ties.
Replace the Servomotor
or encoder.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
Write the motor parame-
ter file to the linear
encoder.
Change to a correct com-
bination of models.
