Help with a usb BOB Spindle problems

[Lahdiel]

I have it wired up right i've checked it, like i said the axis all work and the outputs switch fine but i cant get anything from the 10v output, no terminals give any reading in relation to the 10v terminal so i'd think its floating in relation to everything else, if thats the case would you say the boards busted or i just need to play with more settings

[JAZZCNC]

So which terminal are you calling the 10v terminal.? I know you say you have it wired up correctly but it's not working so maybe you don't.? It's easily done.!

I can't say if it's busted or not but I can tell you that if just 1 setting is wrong or you are on the wrong terminals it won't work and it's more likely to be something like this than being busted.!

The terminal in the corner of the board that's labelled 10v, i'm aware the wires for the spindle aren't hooked up in the picture i sent as i didnt want the spindle to spin up then shut off every time it got an enable signal while i was trying to get a signal from the terminal

Right well, I don't know this board but I've seen plenty like it. I'd take a guess that the 10V is the reference voltage that you would need if you used a potentiometer for analog inputs, etc, the actual terminals you'll need for 0-10V will be ACM and AVI.
DCM and any of the outputs you would use to control Forward or Reverse.

If you show me the VFD I'll tell you which terminals to use but they are often marked with Similair labels ACM = (0V) analog common, AVI = Analog voltage (0-10v)

DCM = Digital common and usually FOR or REV.

Ah okay, i've never seen a lot of those acronyms before, i'm not using a VFD as its for a 190vmc conversion the controller is a lenze534 and i've already sorted the reverse relays for that
I just got the spindle working controlled from an external power supply too so i think im sorted with those connections

I'll try these suggestions and see if i can get anywhere with it

Okay, if I was trying to sort this out this is what I'd be doing:-

1) On the Lenze, establish the +V, Gnd and sense lines. On the Lenze 531, these are pins 9, 7, 8 respectively. The user manual should confirm that, and it sounds as though you know these already with the speed control that you have. From herein I'll use those acronyms ("+V", "Gnd" and "Sense") in relation to the Lenze controller. At least one Lenze manual refers to these as "E", "A", and "S".
2) Confirm Lenze.+V is 10 Volts, or thereabouts wrt the Lenze.Gnd terminal. Don't proceed it this is wildly off. Note, Lenze.Gnd may be (will be) floating above equipment earth - so take care with measurement and avoid shock hazard.
3) On the USB-BoB, confirm with DMM on resistance range, Open-line (OL) - very high resistance (>10MR) between terminal [BOB.ACM] and [BOB.GND]. Do not proceed if not.
4) Repeat for [BOB.10V], to [BOB.GND]. Expected: Open-line (OL) - Do not proceed if not.
5) Repeat for [BOB.AVI] to [BOB.GND]. Do not proceed if not.

At this stage you can expect the BOB variable output to be electrically isolated from the main BoB circuitry, Power everything off.

6) Connect [BOB.ACM] to [Lenze.Gnd]
7) Connect [BOB.10V] to [Lenze.+V]
8) Connect [BOB.AVI] to [Lenze.Sense]

Test. I would not connect the PC to the USB board until I've observed the absence of magic smoke from the BoB.

But that's just me.

She's alive once again! Thanks guys i would never have figured out that 10v was an input on my own doh
I still had the isolation board on mine so it only floated about 3v different to earth ground
Thanks again
