We have a Cadet-V4020 with VAC III D-11 and got error message 082 ALARM P 1001FFFF. We found that the two fuses on power supply board on VAC III was blown they were fuses F2R AND F2S
we replaced them and they blew as soon as we turned power on. Does anyone know what would cause this to happen
the biggest metal box is the spindle drive.
even if the IGBTs are blown the cause of the failure is almost always on the top board.
if you look at the later VAC III spindle drives the lower board is identical and the top board is different (i.e. the previous top board had design issues).
if you look at the latest VAC IV and VAC V spindle drives it is a completely new design and about half the size of the VAC III

you will have a LED error on the actual spindle drive.
get the manual linked on that thread and read up about your error.
the chances of you fixing it yourself are about 1 million to 1.
There are 3 options:
1 buy a new VAC drive from Okuma (~$20k)
2 get it professionally repaired or a refurbished exchange unit (~$6k)
3 scrap the machine
I suspect either there are no LED's on or the red LED is flashing .... this guy has a problem that won't be fixed without the drive removed and taken apart
the leds are too bright to read if they are on, flashing or off.
need to know the 7-segment LED numbers, if M1, M2 and M3 lights are on, off or flashing.
