Mitsubishi Meldas CNC

[ToolGuyFred]

I have a machine fitted with a Meldas 50 CNC which is refusing to start. I have a series of alarm messages on the controller which display in the following order:

AL
o1
91
80
00
o2
91
80
00

then back to AL etc.

The Servo rack PSU doesn't reset, either. I am assuming that the servo rack PSU resets via the serial port on the front and it isn't getting the signal from the controller due to these alarms?

I don't have the manual for this controller. I have found several links online but none of them seem to point to anything useful (although they may once have). Does anyone have a link to a download site or an electronic copy, please?

Thanks.
