big denford triac problems

[Chaz]

ok not 100% on these by any means but i have definitely got 3 phases going to the axis boards
no coolant pump on it, as i don't use coolant really and no tool changer either as i like it without and for what i want i don't need one, just something else to go wrong

Some pics will be good. Some Triacs have wiring diagrams with them, do you have any you can scan / put here for review?

no i'm afraid not, no wiring diagram to speak of, but it is factory fanuc om, and un messed about with, i know that before i had the last meltdown i had low voltage alarms on x,y z, axis boards, i will try and post some pics later on today

Thanks. Ill do some quick googling but pictures will help.

odd thing is the guy i bought it off had ran it for 11 years with no problems with this set up,
now here's the thing, he disconnected the cabling from the phase convertor to facilitate moving the m/c and marked up all cables and where they go, i was very careful to re wire exactly as marked, but if he has made a mistake................

So I've had a quick look at every Denford wiring diagram I can see. I dont see anything where the actual servo drives are actually connected to all 3 phases, they seem to take a single phase for input power. That said, yours might be different.

you may well be right, i need to source boards before any testing can begin, although i don't know if i dare turn on the m/c!

heres a pic not very good i know
BTW the phase convertor is a boost electrical engineering one rated at 8 hp, which i know is miles to big for the denford but it came with it
