9.1.1 List of Alarms

9-4

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

A synchronization error occurred between the SERVOPACK
and the command option module.

Gr.1

Available

A.E03

Command Option Module IF

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
