Hi everyone,

I recently had a problem with my cnc. I tried several things without success, I need your help.
The connection between earth and a damaged wire from the spindle created a short circuit. There was no smoke, the circuit breaker trips. I replaced the damaged wire and now I have the error A.oL and then E.oA.A. when I try to start the vfd.

My setup is: 220v, 800w, 5A, 400HZ, water cooled spindle with a Huanyang VFD 1.5kw. The cable between vfd and spindle is 4 core 16awg shielded.

The spindle seems to be ok. The resistance is 4.2Ohm between each pins (U,V,W not the earth).

Visually the VFD is ok. When I run it witout the cable attached to the spindle there is no error. I tried also to reset settings and apply it again. My setting is:
PD000=0
PD001=0
PD002=1
PD003=400
PD004=400
PD005=400
PD008=220
PD141=220
PD142=5
PD143=4
PD144=3000

Do you have any advice to determine the problem please?

Thanks in advance for your help!
