Need some information on this driver. Have emailed General Controls but have not received a reply back from them. Anybody got a manual for this drive? Model: 29A55-A 3amps input: 28vac/42vdc
Thanks U-all :wave:

Hey Greg,
Here's a link to an Ebay auction for a Dragon Driver. there's a link to the manual somewhere on that page.

Thanks That will get me started.:cheers:

Anyone else using these? It appears that these modules can run AC or DC. I ended up with three, but have no experience with them, so any input or comments would be appreciated.

They have three levels of the Dragon driver. the ones I have are the 29A55-A
All you need to add is a transformer and a stepper. They can be used stand alone as a indexer or wire to a computer.

Here is a copy of the pdf/ manual

I have the same 29A55-A. Its very interesting that they can run off of ac. Can anyone describe their setup? I'm interested in powering them in this manner.

All you need to set them up is in the manual I posted. They only run from AC, they have a built in bridge rectifier to make DC.

Understood, but connecting them to a parallel breakout board is proving problematic for me.

My Breakout provides the following:
1. Enable
2. Direction
3. Step
4.. Common

But the Dragon Driver has the following:
1. Step out
2. Step in
3. +5v out
4. Half/Full step select
5. CW/CCW Select
6. Enable
7. Ground
8. Fast osc
9. Slow osc
10.Ground

Now of course I can understand the ground and enable probably wire up
to common and enable on the breakout board. but I have no idea how I should wire the Direction and Step.

Any help would be appreciated.

BTW, I've read the PDF provided, and its still not clear to me.

The enable from the BOB goes to the enable on the driver.

The common on the BOB goes to the ground pin 7 on the driver.

The step on the BOB goes to the step in on the driver.

The direction on the BOB goes to the CW/CCW select on the driver.

If you want full steps you connect half/full to ground, for half steps leave unconnected.

Step out on driver is left unconnected.

Fast osc and slow osc are left unconnected.

Thanks Packrat. I messed around with it yesterday, and had come to pretty much the same conclusion.

Good to have some confirmation on the connections.

Will be taking my LNC2 box home from work today to test it all out.

This is what it looks like so far:

I have 3 of these. You can power them from either up to 28 volts AC, or up to 40 volts DC. General Controls will not answer questions regarding them.

Do you have data on them. The dip switches I believe are for current limit output. I want to stay below 1.5 amps. On the inputs is 2 step? 5 direction? 7?
Thanks,
Greg

Thank you. I am moving ahead now. Now I am trying to figure out how to intercept thevariable spindle speed on a Emco compact 5 lathe. There is a pot mounted on the front ofthe control board that changes the speindle speed when in manual mode. In cnc mode it wascontrolled by the main computer but the control lines and the mode still elude me. I am retor fitting the lathe to Mach3.
