The speed of program
jogging went below
the setting range
when the electronic
gear ratio (Pn20E/
Pn210) or the Servo-
motor was changed.
Check to see if the
detection conditions
*1
are satisfied.
Decrease the setting of
the electronic gear ratio
(Pn20E/Pn210).

The speed of program
jogging went below
the setting range
when Pn533 or Pn585
(Program Jogging
Movement Speed)
was changed.
Check to see if the
detection conditions
*1
are satisfied.
Increase the setting of
Pn533 or Pn585.
*1
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).

Error 2
For 4-byte parameter
bank members, there
are two consecutive
members with nothing
registered.
–
Change the number of
bytes for bank members
to an appropriate value.
–
The total amount of
bank data exceeds 64
(Pn900 × Pn901 >
64).
–
Reduce the total amount
of bank data to 64 or less.

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.
Confirm that the follow-
ing condition is met:
1/4 ≤ (Servomotor
capacity/SERVOPACK
capacity) ≤ 4
However, the above for-
mula does not apply to
the following products.
• SGD7W-2R8A
SERVOPACK and
SGM7J-A5A
Servomotor
• SGD7W-2R8A
SERVOPACK and
SGM7A-A5A
Servomotor
Select a proper combina-
tion of the SERVOPACK
and Servomotor capaci-
ties.
*1
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.
*1
An unsupported Serial
Converter Unit or
encoder is connected
to the SERVOPACK.
Check the product
combination specifica-
tions.
Change to a correct com-
bination of models.
