Fault 2310 Overcurrent occur for only one drive ACS580
Hi My drive model ACS580-01-145A-4 used about 1 years, but yet recently it show up overcurrent for one specific drive in line. With refer to manual, checked all the motor, cable, and megger the motor and cable insulation phase to phase, phase to earth confirmed ok. Still the inverter tripped, sometimes during start up and sometimes during running for about 10minutes.
Here is the event log:
Fault details
05.81 Output frequency at fault 0.0Hz
05.82 DC voltage at fault 764.77Hz
05.83 Motor current at fault 353.41A
05.84 Motor torque at fault 0.0%
05.85 Main status word at fault 1237 hex
05.86 DI delayed status at fault 0000 0000 0000 0001
As information, we changed the wiring to another drive (same series) beside to test , it work fine and no issue. I understand that inverter trip is to protect the motor, but could it be the inverter itself already defect?
Thanks

Hi
it might also be interesting to know your application, i.e. what load the motor moves and with what operating cycles.
At what voltage is the drive powered?
This is because a voltage on the DC bus of more than 760 V with a 400 V power supply of the drive, could suggest that you have a large inertial load and that during braking, for example, an overvoltage occurs which can cause the failure you have described.
Do you have any other information to give us?
