The number of times for the encoder to clear the procedure error exceeds 11 times.
If the issue persists, set P0.002 to -80 to check the communication quality with the
encoder. If the communication is normal, use DI.ARST to clear this alarm.
Cycle power on the servo drive.
The encoder version read by the servo drive is wrong.
N/A
Replace the motor immediately.
Condition: during general operation, this alarm occurs when the servo drive outputs
current that is over the allowable level specified by the firmware. This alarm protects
IGBT from overheating or burning because of the high current.
Cause:
UVW cable is short-circuited.
1.
Motor wiring is wrong.
2.
The analog signal GND for the servo drive is interfered.
3.
Check the connection between the motor power cable and its connector.
1.
If metal wire is exposed or the wire is torn, the UVW cable can short circuit.
In this case, replace the UVW cable and prevent the metal conductor from
being exposed.
Refer to Chapter 3 Wiring and check the following:
2.
(a) If you do not use the Delta standard power cable, make sure the UVW
wiring sequence is correct.
(b) Make sure the UVW wiring between the servo drive and the motor is
correctly connected.
Check if the analog signal GND is mistakenly connected to another ground
3.
signal (incorrect connection can cause interference). Do not use a common
ground for the analog signal GND and other signal cables. Follow the wiring
instructions in Chapter 3.
