Okuma MV-5A VAC ALARM

[actarus69]

Hello everyone

Okuma MC-5VA NOT MV-5A, SORRY , I WAS WRONG ON THE MODEL

My friend have buy a old '86 Okuma MC-5VA, when he buy the machine (at an auction) every thing was working ok, after the re-installation was complete, when we try to stop the spindle, we have a VAC Spindle drive alarm 109. The technicien said that the machine look ok but voltage was to high on the building at 618V!?!?!?!, that realy suck!!!

Does any one know what can be the trouble!!

thanks for your help
