The setting of the
Fully-closed Module
does not match the
setting of Pn002 =
n.X (External
Encoder Usage).
Check the setting of
Pn002 = n.X.
Make sure that the
setting of the Fully-
closed Module
agrees with the set-
ting of Pn002 =
n.X.

Error (The
capacities of the
SERVOPACK
and Servomotor
do not match.)
The SERVOPACK
and Servomotor
capacities do not
match each other.
Confirm that the fol-
lowing condition is
met: 1/4 ≤ (Servo-
motor capacity/
SERVOPACK
capacity) ≤ 4
Select a proper com-
bination of the SER-
VOPACK and Servo-
motor capacities.

Unsupported
Device Alarm
The motor parameter
file was not written to
the linear encoder.
(This applies only
when not using a
Serial Converter Unit.)
Check to see if the
motor parameter file
was written to the
linear encoder.
Write the motor
parameter file to the
linear encoder.

An unsupported Serial
Converter Unit or
encoder (e.g., an
external encoder) is
connected to the
SERVOPACK.
Check the product
combination specifi-
cations.
Change to a correct
combination of
models.

Motor Type
Change
Detected (The
connected
motor is a dif-
ferent type of
motor from the
previously con-
nected motor.)
A Rotary Servomotor
was removed and a
Linear Servomotor
was connected.
– Set the parameters
for a Linear Servo-
motor and reset the
motor type alarm.
Then, turn the power
supply to the SER-
VOPACK OFF and
ON again.
