Bounce, bounce, bounce, bounce....Brum brum................

Didn't really look at the specs close just read 5 phase in the document transcript.!! . . . Best he checks the motors.? . . . .Artmin do the motors have 8 or 10 wires.?

Thats cus you were toooooooooooooo busy looking at my avatar:lol:

Funny that, I never noticed the Nissan before. Guess I couldn't see the wood for the trees :lol:

A few beers in me now, but I can only count eight wires from each motor. Would that still make the Heiz controller dodgy?

Cheers,

Gavin

Gavin if you wanted to just run the machine and check motors etc then the Heiz controller would probably work ok just don't push the motors to hard. There's only 0.2a difference and it's very unlikely you'll come near that just jogging it around. Just make sure the Heiz is set for parallel wired motors.

How 'hard' you run the motors will make little difference as they'll actually draw the most current when stationary, unless the driver reduces the current there in which case it'll be at very low speed.

Either way, if it gets hot switch it off. Simples...

Thanks guys :tup:

I wasn't sure where you were getting the 2.4A/phase from but I see it now. I think the Heiz controller is 500 Euro + delivery & I see on the website they state the phase current as up to 2.1A. Maybe I'd be better spending the money in a different way.

I'll pull the machine out in the garage to get some good light & take a video of the controllers. I'll also contact ITT/Burny again & ask them to send me the spec. sheets for the driver board, as surely that has to be standard. Initially they told me that they wouldn't be of use to me as HME wrote their own software, but I now understand that must be for the HPGL board. I'm looking forward to ripping that one out :naughty:

If mating breakout to the driver was going to be difficult, would I be better with something like this?

or this?

The first link, M542 drivers, is ideal. Not sure if it's the cheapest - just look for 3 drivers with 542 in the part number and a suitable breakout board and you'll be fine.

The second link is pretty poor as the driver only goes up to 30V and the motor torque (and therefore feedrate) is proportional to the applied voltage. Plus you'd be running very close to the maximum current for those drivers.

Again if you can check the rectified voltage from the transformer with a multimeter and it's less than 50V, but significantly less then you can keep it as long as it can deliver enough power. Could you measure the diameter and height of the transformer so we can estimate the output current?

It is rather distracting.

Those motors don't have much torque (1.5Nm) for nema 34. The datasheet only mentions A and B phases and 8 wires so looks like it's 2 phase. Standard 5-phase stepper motors are 0.72° step angle, whereas this one says 1.8° which is standard for 2-phase 200 step/rev. I've got a fairly big Nema 34 stepper motor lying around somewhere. You can get stepper drivers for them on eBay, but I just made a simple unipolar drive for it and it works. Never actually used it - one day I'll make a proper bipolar drive for it. It's a good candidate for my lathe I reckon...

Just looked again she still gives me a stiffy..!!! . . Errr errr . . No I mean I've just looked at the sheet again and realised I miss read the document transcript.! It reads like 5 phase motors but it relates to 5 step angle. . .Doh
