    Unknown Huanyang error code EEP

    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?

    It is either a CPU fault or an E'prom fault

    Was this running when you had the power outage as it could well be the IGBT's as well if it was running and had a power cut

    How has the input power been wired to the VFD Drive and is this single phase or 3 phase supply

    The VFD was powered on but not running when the outage occurred.

    This is single phase supply. 220 wired into the mill cabinet and enabled through relay so it turns on with the rest of the mill.
