C10
BURN-UP CHKDET
The servo motor made a reckless run
1. The motor U, V, W wiring order is incorrect
2. Failure of the servo pack
3. Encode failure
1. Check motor wiring.
2. Replace the servo pack
3. Replace the motor
C80
ENC CLEAR ERROR
1. Failure of the servo pack
2. Encode failure
1. Replace the servo pack
2. Replace the motor
C90
ENC COMMUNI ERROR
Failure in the communication between the servo pack and
encoder
C91
ENC COM POS ERROR
C92
CB0
ENC COM TINE ERROR
ENC ECHOBACK ERROR
1. Encoder wiring is incorrect
2. Inappropriate encoder cable generates noise
3. Long encoder cable generates noise
4. Encoder cable is close to a large current power cable
5. FG varies by the influence of motor-side device (welder)
6. Encoder is subject to excessive vibration impact
7. Failure of the servo pack
8. Encode failure
1. Check the encoder wiring.
2. Use the cable which meet the specification
3. Wiring length shall not exceed 20m
4. Keep the encoder cable free from surge
5. Ground the system. Prevent current division to the FG
on PG side.
6. Prevent machine vibration, or install the motor properly
7. Replace the servo pack
8. Replace the encode
CA0
ENC PRM ERROR
Encoder parameter is incorrect
1. Failure of the servo pack
2. Encode failure
1. Replace the servo pack
2. Replace the motor
CC0
MULTI LM MISCOMPARE
Encoder parameter is incorrect
1. The user integer in the servo pack is incorrect.
2. The multi-turn limit value of the encoder was incorrectly
set up.
3. Encode failure
1. Check Pn554
2. Reset the gear ratio of the Pn010.
3. Replace the motor
D00
POS-DEV OVER
The deviation of position in the servo on status exceeded
Pn618.
1. Servo pack circuit board failure
2. The motor U, V, W wiring is incorrect
3. Bad adjustment of motor gain
4. The frequency of the position command pulse is too high.
5. The excessive level of position deviation (Pn618) is
inappropriate.
6. The load condition mismatches motor specification.
1. Replace the servo pack
2. Check motor wiring.
3. Increase the set values of the speed loop gain (Pn506)
and position loop gain (Pn508).
4-1. Slowly raise/lower the frequency of the position command
pulse.
4-2. Check the electronic gear ratio again.
5. Set the excessive level of position deviation (Pn618)
to an appropriate value.
6. Check the load again.
D01
SV OFF POS-DEV OVER
The position deviation at servo off is too large.
Prevent the motor from moving during servo off.
D02
SV ON POS-DEV OVER
At servo-on while there is residual position deviation,
the command pulse is inputted during operation at
limit speed, and the position deviation excess level
(Pn618) will be exceeded.
- Prevent the motor from moving during servo off.
- Set the limit speed level (Pn620) to appropriate an value
