Sorry for my bad English!
I need help for my HY02D223B inverter
During program execution, the inverter shows an E.L.u.n error and the spindle stops rotating.
The problem does not have a clear recurrence, it can run for 2 minutes and manifest itself, and it can take 2 months without manifestation, under different cutting / punching loads.
After the restart, everything starts anew, and the problem may or may not be repeated.
I have had this machine for 5 years, but in the last one it started to make me this problem.
I haven't changed a thing.
Everything is set up by the manufacturer of my CNC.
