How To Connect PEND and ALM Outputs on HBS860H Hybrid Stepper Drives

[francoCNC]

Hi Guys - many of us have used these HBS860H Closed Loop Hybrid Stepper drives on our conversion projects. Does anybody know the correct way to connect the PEND or ALM driver outputs to the Acorn inputs? It looks like it's easy to connect a single drive to a single input but how do you connect multiple drives to the Acorn board? Do you use multiple inputs? Or, is there an easy way to connect all of them to a single input? Any help would be much appreciated.

Thanks!

Here is the description of the driver outputs:

Here is the diagram from the manual:

Did you watch this Brad, should pertain to your drives

I was literally just watching that video and was about to drop the link in this thread! Thank you for making it.

I'm not sure if the drive alarm output is NC or NO. If they are NC, I guess I can wire them up in series and use one Acorn input, right?

If, for some reason, they are NO I do have the programming cable and I believe I can invert the logic in the drive software.

Assuming you don't have the programming cable and you can not invert the NO output to NC (and wire in series to one Acorn input) how should I go about connecting three NO alarm signal outputs to the Acorn? Can I simply use three different Acorn inputs?

Thanks!

OK - I just ran out to the garage and put the Multi-Meter on the Driver Alarm Output terminals - they appear to be NO.

Is it possible to use three different Acorn inputs to interface with three different driver alarm output signals? If so, that's a really easy way to fix this.

Or, can I wire the three driver alarm outputs up in parallel to one Acorn input?


Thanks,

It is my understanding that you can change the output in software. Eventually I will buy two more and install them on another Dyna DM2400 after I sell the first one!

Thanks for your help with this. I was able to get things to work with NO alarm outputs wired in parallel to a single Acorn input. Here's the video:

Thanks franco - good vid. Can you point me to the HBS860 software you speak of?
cheers

Franco,

Thanks for the nice video! I have the cousins to the closed loop steppers you are using. Mine are the 8082H but mine have all the same switch settings and mine are black.

I have the Manual, the programming software and the cable. My concern with saying" these are like switches" is that the manual says they can "sink or source 24 VDC" which means they are not switches but open collector of some type.

I see they do work when wired in parallel and with a N.O. 24 vdc circuit. I'm not sure they will work as described if changed and here is why. I downloaded the "PROTUNE" software from AT's site and connected to one of the drives and I see it does not give you N.O. or N.C. as choices but some other choices that are a bit foreign to me. Not active high or active low, but something I can't recall right now. I think it is actually the choice of what I would call the "sink or source" option and I'm not sure that equates with N.O. and N.C as we think of it.

I'd prefer the N.C. alarm circuit as well but in this case the N.O. may be the only way they will work properly.

In the meantime, I had three of these ready to test out on Acorn, none worked! I have another thread on that issue and I'm sending them back to AT for their testing. And yes, I wired them just like Marty's video and the Centorid drawing. So unless I have an Acorn board that does not work right, I must have three drives that are a bit squirrely. I'm not a newbie at automation, I've been doing it for over 20 years!

Good video,

Dave C.

Here is a link to the software:

I have to install both the Chinese and the English versions. English doesn't seem to work without the Chinese version installed, as well.

Franco, thanks for that. Did you report the software issue?
They should fix that....
