Zenford Zeigler Retrofit

Thanks guys. Will be working on the machine this afternoon. Appreciate the help. Will let you know what i find.

Well no great luck with the transistors / diodes on the bottom of the drive. I pretty much tested all the drives and they seemed good. No shorted components, or any high / low diode drops. The drives have 2 sections that can separate. The heatsink side has the transistors, diodes and some resistors, and that plugs into the pcb (control circuit). I ended up switching over one of the good running drives transistor section with a faulty full speed on enable transistor section, and the fault stayed with the pcb control, not the transistor section.

Will have to look into it a bit more, checking components etc.

Anything else you recommend to check out in particular?

Did you already replace all old capacitors? They are normally a ticking time bomb in power electronics.

Hi Mark

I havnt changed out any capacitors yet. I was happy when none of them gave me an unexpected fireworks show when i first gave them power. I will change them out before i go much further.

Its nice and wet here at the moment Tommy.... and dark. haha

I can live with having 3 drives only, but really, out of 9... Surely the electronics gods can smile upon me and show me a little love.

We will see......................

Cheers guys

Hey Snoozer,
3 drives is pretty good and at least you'll be able to get the machine moving. Could I trouble you for some more pics of the wiring diagrams of the limit switches, spindle gear change, and tool changer. If you scanned the wiring diagrams and the hyperloop manual I would send you some beer money.
Cheers
Marcel.

Will have to work out how to scan the drawings. They are big. I woukdnt mind a elecrronuc copy myself. I will see what i can do. Hopefully your not in to much of a hurry.

Don't worry if it too much hassle, would you be able to tell me the command pins for the hyperloop +/- 10v ?.
Gone with a clear earth approach to the old wiring.
Got anymore progress on your machine ?

Sorry, been flat out. Havnt had a chance to do much lately. The command pins are pins 2 and 12 in the first pic of the spindle wiring diagram.
