8.1.1 List of Alarms
8-4
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.C20 Phase Detection Error The detection of the phase is incorrect. Gr.1 N/A
A.C21 Hall Sensor Error The hall sensor is faulty. Gr.1 N/A
A.C22
Phase Information
Disagreement
The phase information does not match. Gr.1 N/A
A.C50 Polarity Detection Error The polarity detection failed. Gr.1 N/A
A.C51
Overtravel Detection at
Polarity Detection
The overtravel signal was detected at polarity detec-
tion.
Gr.1 Available
A.C52
Polarity Detection
Uncompleted
The servomotor was turned ON under the condition of
polarity detection uncompleted.
Gr.1 Available
A.C53
Out of Range for Polarity
Detection
The moving distance exceeded the set value of Pn48E
during polarity detection.
Gr.1 N/A
A.C54 Polarity Detection Error 2 The polarity detection failed. Gr.1 N/A
A.C80
Absolute Encoder Clear
Error
The data for the absolute linear scale was not properly
cleared or set.
Gr.1 N/A
A.C90
Encoder Communications
Error
Communications between the SERVOPACK and the
linear scale is not possible.
Gr.1 N/A
A.C91
Encoder Communications
Position Data Error
A linear scale position data calculation error occurred. Gr.1 N/A
A.C92
Encoder Communications
Timer Error
An error occurs in the communications timer between
the linear scale and the SERVOPACK.
Gr.1 N/A
A.CA0 Encoder Parameter Error Linear scale parameters are faulty. Gr.1 N/A
A.Cb0 Encoder Echoback Error
Contents of communications with linear scale are
incorrect.
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 servomotor 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,
Pn584 limits the speed if the servomotor power is
turned ON. If Pn584 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.d30 Position Data Overflow The position feedback data exceeded ±1879048192. Gr.1 N/A
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.
