MECHATROLINK
Communications
ASIC Error 1
ASIC error occurred in the MECHATROLINK communications. Gr.1 N/A
A.b6b
MECHATROLINK
Communications
ASIC Error 2
ASIC error occurred in the MECHATROLINK communications. Gr.2 N/A
A.bF0 System Alarm 0 "Internal program error 0" of the SERVOPACK occurred. Gr.1 N/A
A.bF1 System Alarm 1 "Internal program error 1" of the SERVOPACK occurred. Gr.1 N/A
A.bF2 System Alarm 2 "Internal program error 2" of the SERVOPACK occurred. Gr.1 N/A
A.bF3 System Alarm 3 "Internal program error 3" of the SERVOPACK occurred. Gr.1 N/A
A.bF4 System Alarm 4 "Internal program error 4" of the SERVOPACK occurred. Gr.1 N/A
A.C10 Servo Overrun Detected The servomotor ran out of control. Gr.1 Available
A.C80
Absolute Encoder Clear
Error and Multiturn Limit
Setting Error
The multiturn 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 are incorrect. Gr.1 N/A
A.CC0
Multiturn Limit
Disagreement
Different multiturn limits have been set in the encoder and the SER-
VOPACK.
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 Overflow
Position error exceeded the value of excessive position error alarm
level (Pn520) when the servomotor power is ON.
Gr.1 Available
A.d01
Position Error Overflow
Alarm at Servo ON
This alarm occurs if the servomotor power is turned ON when the
position error is greater than the set value of Pn526 while the servo-
motor power is OFF.
Gr.1 Available
A.d02
Position Error Overflow
Alarm by Speed Limit at
Servo ON
When the position errors remain in the error counter, Pn529 limits
the speed if the servomotor power is turned ON. If Pn529 limits the
speed in such a state, this alarm occurs when position references are
input and the number of position errors exceeds the value set for the
excessive position error alarm level (Pn520).
Gr.2 Available
A.d10
Motor-load Position Error
Overflow
During fully-closed loop control, the position error between motor
and load is excessive.
Gr.2 Available
A.E02
MECHATROLINK
Internal Synchronization
Error 1
Synchronization error during MECHATROLINK communications
with the SERVOPACK.
Gr.1 Available
A.E40
MECHATROLINK
Transmission Cycle
Setting Error
The setting of the MECHATROLINK transmission cycle is out of
the allowable range.
