DQ860MA Driver from Wantai motors

[orcaz1]

Hello, newbie here, never done this before, bought some stepper motors, power supplies and DQ860MA Drivers from a Chinaman for a RF30? table top milling machine. ( I got a great deaI from this guy) it's all fitted out and seems to be running O.K. after about 5 broken cutters and a couple of crashes. I'm using EMC2 software for the controller and have reached the stage where I need to fine tune this system.
It's quite a learning curve but at least I am no longer standing at the mill laboriously turning handles anymore, just sitting by the big red button and watching it go. The EMC2 requires driver timing for step and direction. I notice this is available for a few different drives on the market, but have found none for the DQ860MA. The linuxcnc website suggests a starting point timing of 10000 ns, if you don't know what timing your drives need, and that's what I'm running now. Has anyone else got these drives and EMC2 and have the info I'm looking for? if so I would greatly appreciate you sharing it. P.S hope I'm posting in the correct forum.

I am trying to add a couple of pics here

Hi All,

I am also having problems on trying to figure out:
Step Time ns Step Space ns Dir. Hold ns Dir. Step ns
parameters for this controllers. I have search every where and no luck. Would be appreciated if any body can help with this problem. Hopefully, some one has figure out these parameters. Thanks.

I'm use same driver from china. I'm setting current by 0.7 * motor amps. It work ok. If you setting full current by name plate of motor. Motor will jeck.

Why do you have 3 power supplies and have you tried contacting the seller

Hi,

Thanks for the information. Is the current by 0.7*motor amps for the peak or RMS? Cool machine you have retrofit. Nice picture.

Maybe a little late, but I have found a datasheet of the DQ860MA. Indeed it is in german, but doesn´t matter, the info you need I have marked with the red circle.
Also I have uploaded the whole datasheet:
Hope it helps..

I'm using DQ860MA, DQ542MA drives with linux EMC2.
My timing values in EMC2 are 100, 100, 100, 100 ns. It works without losing any steps or pulse errors.....but I cut off all optocouplers on china made BOB (because the drivers already have the optocouplers inside).
Those Wantai breakout-board optocouplers are superslow...

That's probably why they give them away free when you buy motors and drivers from them.

Thank you very much for posting the timing requirements.
