A.042:
Parameter Com-
bination Error
The movement speed
of advanced autotun-
ing went below the
setting range when
the electronic gear
ratio (Pn20E/ Pn210)
or the Servomotor
was changed.
Check to see if the
detection conditions
*2
are satisfied.
Decrease the setting of
the electronic gear ratio
(Pn20E/Pn210).

A.044:
Semi-Closed/
Fully-Closed
Loop Control
Parameter
Setting Error
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 Mod-
ule agrees with the setting
of Pn002 = n.X.

A.050:
Combination
Error
(The capacities of
the SERVOPACK
and Servomotor
do not match.)
The SERVOPACK and
Servomotor capaci-
ties do not match
each other.
Check the capacities to
see if they satisfy the
following condition:
Select a proper combina-
tion of the SERVOPACK
and Servomotor capaci-
ties.

A failure occurred in
the encoder.
Replace the encoder
and check to see if the
alarm still occurs.
Replace the Servomotor
or encoder.
–
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the
SERVOPACK.
–
A.051:
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 lin-
ear encoder.
Write the motor parame-
ter file to the linear
encoder.
page 5-20
An unsupported Serial
Converter Unit or
encoder (e.g., an
external encoder) is
connected to the
SERVOPACK.
Check the product
combination specifica-
tions.
Change to a correct com-
bination of models.

A.070:
Motor Type
Change Detected
(The connected
motor is a differ-
ent type of motor
from the previ-
ously connected
motor.)
A Rotary Servomotor
was removed and a
Linear Servomotor
was connected.
–
Set the parameters for a
Linear Servomotor and
reset the motor type
alarm. Then, turn the
power supply to the
SERVOPACK OFF and
ON again.

A.080:
Linear Encoder
Pitch Setting
Error
The setting of Pn282
(Linear Encoder Scale
Pitch) has not been
changed from the
default setting.
Check the setting of
Pn282.
Correct the setting of
Pn282.
