How to clear the
alarm?
Revision December, 2017
The time to clear the encoder exceeds the limit.
If the issue persists, set P0.002 to -81 to check the communication quality
with the encoder. If 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 out because of the
high current.
Causes:
1. UVW cable is short-circuited.
2. Motor wiring is wrong.
3. Interference on the analog signal GND for the servo drive.
1. Check the connection between the motor power cable and its
connector. If metal wire is exposed or the wire is torn, the UVW cable
can short-circuit. In this case, please replace the UVW cable and
prevent the metal conductor from being exposed.
2. Refer to Chapter 3 Wiring and check the following:
(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.
3. Check if the analog signal GND is mistakenly connected to another
ground signal (incorrect connection can cause interference). DO NOT
use a common ground for the analog signal and GND. Follow the wiring
instructions in Chapter 3.
