I have a Huanyang HY02D223B on my milling machine.
We had a power outage today and now I have no power to the mill spindle and the display reads EEP. Pressing the reset button flashes the F00.00 message and then returns to EEP.

I've searched the manual and other online resources but can't find this particular code.

Anyone know what it means? Does it mean it's time to buy a new inverter?
