A.C80
Absolute Encoder Clear Error
and Multi-turn Limit Setting
Error
The multi-turn for the absolute encoder was not properly
cleared or set.
Gr.1 N/A
A.C90
Encoder Communications
Error
Communications between the SERVOPACK and the
encoder is not possible.
Gr.1 N/A
A.C91
Encoder Communications
Position Data Error
An encoder position data calculation error occurred. Gr.1 N/A
A.C92
Encoder Communications
Timer Error
An error occurs in the communications timer between the
encoder and the SERVOPACK.
Gr.1 N/A
A.CA0 Encoder Parameter Error Encoder parameters are faulty. Gr.1 N/A
A.Cb0 Encoder Echoback Error Contents of communications with encoder is incorrect. Gr.1 N/A
A.CC0 Multi-turn Limit Disagreement
Different multi-turn limits have been set in the encoder and
the SERVOPACK.
Gr.1 N/A
A.CF1 *
Feedback Option Module
Communications Error
(Reception error)
Reception from the feedback option module is faulty. Gr.1 N/A
A.CF2 *
Feedback Option Module
Communications Error (Timer
stop)
Timer for communications with the feedback option module
is faulty.
Gr.1 N/A
A.d00 Position Error Pulse Overflow
Position error pulses exceeded the value set for parameter
(Pn520) (Excessive Position Error Alarm Level).
Gr.1 Available
A.d01
Position Error Pulse Overflow
Alarm at Servo ON
Position error pulses accumulated too much. Gr.1 Available
A.d02
Position Error Pulse Overflow
Alarm by Speed Limit at Servo
ON
After a position error pulse has been input, Pn529 limits the
speed if the servo ON command is received. If Pn529 limits
the speed in such a state, this alarm occurs when the position
references are input and the number of position error pulses
exceeds the value set for parameter Pn520 (Excessive Posi-
tion Error Alarm Level).
Gr.2 Available
A.d10 *
Motor-load Position Error
Pulse Overflow
Position error between motor and load is excessive when
fully-closed position control is used.
Gr.2 Available
A.E00
Command Option Module IF
Initialization Timeout Error
Communications initialization failed between the
SERVOPACK and the command option module.
Gr.2 Available
A.E02
Command Option Module IF
Synchronization Error 1
A synchronization error occurred between the SERVOPACK
and the command option module.
Gr.1 Available
A.E03
Command Option Module IF
Communications Data Error
An error occurred in the data of communications between
the SERVOPACK and the command option module.
Gr.1 Available
A.E40
Command Option Module IF
Communications Setting Error
An error occurred in establishing communications (settings)
between the SERVOPACK and the command option
module.
Gr.2 Available
A.E50
Command Option Module IF
Synchronization Error 2
A error occurred in synchronization between the
SERVOPACK and the command option module.
Gr.2 Available
A.E51
Command Option Module IF
Synchronization
Establishment Error
A error occurred in establishing communications between
the SERVOPACK and the command option module.
Gr.2 Available
A.E60
Command Option Module IF
Data Communications Error
A error occurred in communications between the SERVO-
PACK and the command option module.
Gr.2 Available
A.E61
Command Option Module IF
Synchronization Error 3
There was a change in timing of synchronization between
the SERVOPACK and the command option module.
Gr.2 Available
A.E70

Detection Failure
Detection of the command option module failed. Gr.1 N/A
A.E71
Safety Option Module
Detection Failure
Detection of the safety option module failed. Gr.1 N/A
A.E72 *
Feedback Option Module
Detection Failure
Detection of the feedback option module failed. Gr.1 N/A
