Hi ,

I hve a Matsuura MC 760 V with YASKAWA Electric control system type YASNAC MX1 Type ENCM-CP356.
Machine does not start up, an error message as follows is dispayed on the screen:
MM-01 Error
#30 E4:16:820.

I have checked tru the electric fundamentals. Machine has a healthy 3 phase+neutral 220/125 V supply, the DC power supply has all its output voltages ( +24V, +15 V, +5V, -15 V, clearly labelled on the power supply unit)
No overcurrent trips , and a number of internal LEDīs are on, exactly as in the other identical machine we have, which functions correctly.

Can anybody please help with an error code listing, schematics of the electronics ( we have the electrical circuit diagrams) or any relevant service documentation.

All help very welcome, and we will of course pay for the documentation supplied.

Best regards
