A.04B:
Converter Parameter
Setting Error
(The parameter data in
the power regeneration
converter is incorrect.)
Power regeneration converter
failure
−
The power regeneration converter
may be faulty. Replace the power
regeneration converter.
A.050:
Combination Error
(The SERVOPACK and
servomotor capacities do
not correspond.)
The SERVOPACK and servomo-
tor capacities do not match each
other.
Check the capacities to see if they
satisfy the following condition:
(Servomotor capacity)/(SERVO-
PACK capacity)
≥
1/4, and (Servo-
motor capacity)/(SERVOPACK
capacity)
≤
4.
Select the proper combination of
SERVOPACK and servomotor
capacities.
Encoder failure
Replace the servomotor and see if
the alarm occurs again.
Replace the servomotor (encoder).
SERVOPACK failure
−
The SERVOPACK may be faulty.
Replace the SERVOPACK.
A.051:
Unsupported Device
Alarm
An unsupported serial converter
unit, serial encoder, or external
encoder is connected to the SER-
VOPACK.
Check the product specifications,
and select the correct model.
Select the correct combination of
units.
A.052:
Motor Type Setting
Mismatch
(The Motor Type/Appli-
cation Selection Setting
(Pn01E.0) does not
match the motor parame-
ter written inside the
SERVOPACK.)
The Motor Type Setting
(Pn01E.0) is wrong.
Check the parameter setting
(Pn01E.0) and the servomotor that
is used in combination with the
SERVOPACK.
Correct the Motor Type Setting
(Pn01E.0) according to the com-
bined servomotor.
A mistake occurred in writing the
motor parameter file.
Check the model of the combined
servomotor from the product infor-
mation monitor in SigmaWin for
the
Σ
-V-SD (MT).
Write the motor parameter file in
the SERVOPACK according to the
combined servomotor.
A.053:
Winding Selection
Setting Mismatch
(The Winding Change
Setting (Pn01E.1) does
not match the motor
parameter written inside
the SERVOPACK.)
The Motor Type Setting
(Pn01E.0) is wrong.
Check the parameter setting
(Pn01E.0) and the servomotor that
is used in combination with the
SERVOPACK.
Correct the Motor Type Setting
(Pn01E.0) according to the com-
bined servomotor.
The Winding Change Setting
(Pn01E.1) is wrong.
Check the parameter setting
(Pn01E.1) and the motor that is
used in combination with the SER-
VOPACK.
Correct the Winding Change Setting
(Pn01E.1) according to the com-
bined motor.
A mistake occurred in writing the
motor parameter file.
Check the model of the combined
servomotor from the product infor-
mation monitor in SigmaWin for
the
Σ
-V-SD (MT).
Write the motor parameter file in
the SERVOPACK according to the
combined servomotor.
A.054:
Unsupported Winding
Selection Alarm
(The combination of the
SERVOPACK and ser-
vomotor does not sup-
port winding selection)
The combination of the SERVO-
PACK and motor does not allow
winding selection.
−
Change the combination of the
SERVOPACK and servomotor.
