    Exclamation Problems with Mori MV55

    First of all, sorry for my bad english.

    We have Mori Seiki MV55, 1984 and it wont start hydraulics or do anything else.

    When i turn the power on, num.5 faultyled in spindle servo unit is on. Control panel gives ER1 and in parameters it says spindle error.

    I am not an electrician but i did check the powercabels that goes into the spindle servo unit and the midle one is 0(ground). Not sure but i guess that its somewhere short-circuited.


    Back to be amazed by this piece of junk->

    Alarm 5 on the spindle drive , you have poped the 3.2 amp fuse on the spindle pcb. Its a 3.2a S fuse Yellow charcters. Its small green fuse, if there blown, they show a white flag in the small window. These somtimes "pop" over time , just replace it with the same type of fuse. is located top middle of the pcb, 4 to five inches from the top.
