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.Quote:

Mike,
What's the model number on the front of the spindle drive?

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
