Minit lathe - can you help ID my wiring?!

[HankMcSpank]

Thanks to John's comments, I now have enough to be getting on with, so Gary - no need to photograph your wiring.

Also, someone on the zone also pointed me to the wiring diagrams on the little machine shop, where I found the following wiring doagram, which at least outlines what the aformentioned connector codes are for (& this marries nicely with John's info)...

Many thanks.


PS What's with editing Subject headings? I corrected the typo using 'advanced edit' ...but it still shows up as minit lathe?!

Having had fever all week (stuff swine flu - this was much more serious - man flu), it's fortunately waned sufficiently this evening to take a closer look at my dead board.


I think I've found the fault ...about 25% of the components on the PCB's lower surface appear to have been nuked ....



(surprisingly...there was no inkling of those scorch marks until the board was removed from the recess)



Not looking like such a good buy now! (but to fair the seller did say it would need a new board - but oh no, did I pay much attention - nah, I'm way too cocksure thinking I could likely fix it! ).

I don't suppose anyone has a less knackered motor speed control board that I can buy/fix? ...this one's beyond the pale!

Out the frying pan & into the fire ...there's nobody holds stock of the pucka replacement (not that I[d pay eighty quid anyway), so John S pointed me to a suitable Danfoss control board.

well, it turned up today & there are a few spade connections that aren't obvious!




There are an awful lot of connections on it & just wondered if anyone here has a clue as to what they refer to...

L1 & L2 I guess are mains

two unmarked Spade connectors (I'm assuming these are the DC out)

SP1, SP2 & SP3 I guess are the speed control pot connectors.

INH presumably means inhibit (though it's not clear whether this is an input or output)

A1 (two spade connectors)

F1 (one spade connector)

A2/F2 (two spade connectors)

That is a Vari-speed drive and the two terminals are for a current sense resistor to set up the drive for various size motors, a bit like resistor settings on stepper drives, pm me your e-mail address and I'll send you a pdf of the manual.
