Error code E.L.u.n - during work with CNC

[mitakata_net]

Hello,
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.

That error is a low voltage input error. Check the voltage on your input lines, the VFD could also be dead due to some burned components

If it was set by the manufacture does not mean that it was set correctly.

How is the input power wired to the VFD Drive, what Kw is your spindle motor

You could also check your VFD drive to Spindle wiring this may have a bad connection.
