Operator Panel lights flashing

[Chasiboy]

I have an OKUMA HOWA Milac 415v milling machine with a Fanuc 21i-M controller and the operator panel lights are all flashing on and off.

I attempted to make an all data backup but when I got to parameter 313 and did an NO. SEARCH, the search took me to parameter 801 and then I got the following message: Non Maskable Interrupt - Turn machine off.

When I turned it back on, I got the flashing lights. The CNC display and the MDI Panel seem to work somewhat; I can see the status of the coordinates, the tool parameters, etc, but the flashing lights prevent me from typing input or accessing MDI Mode, Manual mode, etc.

Oh yes, and the CNC display shows a blinking EMG error.

Any Ideas?

Thanks,
Chas.

I released the emergency stop button and all is well.

Nice!

Atleast you figured it out before calling a Tech in.

I discovered that my emergency stop button was depressed.
Releasing the Emergency Stop and rebooting the control fixed the blinking lights.
