    Smile Spindle alarm

    I know squat about Mistu alarm codes, but moving a machine can
    cause problems common to all:

    Check the quality of your 3-ph power to the machine.
    A difference in voltage or amperage available to the machine
    (compared to where the machine was installed before) has caused
    trouble for many.

    Is there a voltage selector (230/240/280/300 etc...)?
    It must match your available power.

    Do you run it off of a phase Converter?

    If this is a Fanuc spindle amp, alarm 33 usually means an open regen resistor on the mother board. There are two of these 100 ohm high watt resistors.
    You can sometimes get by soldering a new one onto the board. Otherwise
    you must replace the amp. What kind of machine, a hobber, drill, mill or what?

    Mike,

    According to the Mitsubishi manual, alarm code 33 is an overvoltage alarm.

    This is a link to the troubleshooting manual, should be of some help.

    it is likely that either your sf-pw p.s. is going out or you have some shorted modules in the bse unit.if you still need help give me a fax number and i can fax you some detailed info on a quick easy way to check the base unit with an ohm meter.good luck
