12.2 Errors in Fully-closed Loop Control
Alarm Number: Alarm
Name (Alarm
Description)
Cause Investigative Actions Corrective Actions
A.041:
Encoder Output Pulse
Setting Error
The encoder output pulse (Pn212) is
out of the setting range and does not
satisfy the setting condition.
Check the parameter
Pn212. Set Pn212 to a correct
value.
A.042:
Parameter Combination
Error
The speed of program JOG operation
(Fn004) is lower than the setting
range after having changed the setting
of Pn533 “Program JOG Movement
Speed.”
Check that the detection
conditions is satisfied.
Increase the setting for
Pn533 “Program JOG
Movement Speed.”
A.511:
Overspeed of Encoder
Output Pulse Rate
The pulse output speed upper limit of
the set encoder output pulse (Pn212)
is exceeded.
Check the encoder output
pulse output setting
Decrease the setting of the
encoder output pulse
(Pn212).
A.8A0:
External Encoder Error
An external encoder fault occurred. -
Replace the external
encoder.
A.8A1:
External Encoder Error
of Module
A serial converter unit fault occurred. -
Replace the serial con-
verter unit.
A.8A2
External Encoder Error
of Sensor
An external encoder fault occurred. -
Replace the external
encoder.
A.8A3
External Encoder Error
of Position
An absolute external encoder fault
occurred
-
The absolute external
encoder may be faulty.
Refer to the encoder man-
ufacture’s instruction
manual for corrective
actions.
A.8A5
External Encoder Over-
speed
The overspeed from the external
encoder occurred.
-
Replace the external
encoder.
A.8A6
External Encoder Over-
heated
The overheat from the external
encoder occurred.
-
Replace the external
encoder.
A.CF1:
External Encoder Com-
munications Error
Wiring of cable between serial con-
verter unit and SERVOPACK is
incorrect or contact is faulty.
Check the external
encoder wiring.
Correct the cable wiring.
The specified cable is not used or the
cable is too long.
Confirm the external
encoder wiring specifica-
tions.
Use the specified cable
with max. 20 m length.
A.CF2:
External Encoder Com-
munications Timer Error
Noise interferes with the cable
between serial converter unit and
SERVOPACK.
-
Correct the wiring around
serial converter unit, e.g.,
separating input/output
signal line from main cir-
cuit cable or grounding.
A.D10:
Motor-load Position
Error Overflow
Motor rotation direction and external
encoder installation direction are
opposite.
Check the servomotor
rotation direction and the
external encoder installa-
tion direction.
Install the external
encoder in the opposite
direction, or reverse the
setting of the external
encoder usage method
(Pn002.3).
Mounting of the load (e.g., stage) and
external encoder joint installation are
incorrect. Check the external
encoder mechanical con-
nection
Check the mechanical
joints.
