Need Help!- Machine Down, Spindle Won't Work!

[tjarco]

Haas VF3, 1993

The problem I'm having is I cannot get the spindle to turn on. When I tried to change a tool an alarm comes on (#149) that says the spindle is turning but it is not. My spindle drive display shows failure code CPF00. Has this happened to anyone and what did you do to to fix it?

Thanks

what does it do when you give it a M19 command in MDI?

alarm... spindle turning

I would guess it is your drive that needs to be replaced. We had the problem on a vf0 with a magnatek drive and it was bad capacitors on the drive if I remember right.

your fault is with the shot pin switch which locks the spindle in position for tool change.
remove the head gaurd and the part you are looking for is on the right hand side of the
spindle motor .clean or change the switch and that should fix the problem.

captian is right I didn't think they still used that style in 93 but that does generate the 134 alarm also.

First thing - fault is definately not with shot pin.
Second thing fault is definately with your spindle drive.
I presume your spindle drive is a magnatek drive?
Here is the manual (link)

Page 55 decribes your fault.
It suggests to unplug the control pcb or replace it?
Thats as far as I can help though - as I havn't taken one apart myself.
May end up that you need a new drive.
Hope this helps.
