    UB1 and stepperonline closed loop driver wiring

    Hi, new here and trying to figure out the wiring of the UC300ETH + UB1 and Stepperonline closed loop driver CL86Y that I've purchased to modernise a knee-mill which had a antique sinumerik3 control system and dc servos.

    I've almost no previous experience in I/O, so in this project I've probably, (ok definitely) bitten off more than I can chew. That being said, please forgive me for my lack of knowledge.

    So, I'd appreciate any help of how to connect the Stepperonline closed loop driver CL86Y to the UB1.

    Driver manual:
    https://www.omc-stepperonline.com/do...op-drivers.pdf

    UB1
    http://www.cncroom.com/downloads/UB1...al%20E15R0.pdf

    I've read the UB1 and CL86Y manuals back and forth but cant figure out how to properly connect the MF, ALM and Pend signals of the stepper driver to the UB1 for proper function.

    Personally, I wouldn't even bother with the MF (Enable) or the Pend. Not sure what you would even use the Pend for?
    If you want to use the MF, just wire it to a UB1 output pin.

    Here's some info on wiring an Alarm signal.

    Thanks Gerry, ok, perhaps better to skip enable just as you say.

    Neither I understand what pending would be used for, so I was hoping to get some explanation of this.

    In a closed loop stepper system, an error in any if the drivers would trigger the alarm which I intended to wire to the UB1 safety circuit. So,without alarm triggered it will then work as enable, right?

    I've searched and also found the thread link you're referring to, but there the alarm is not connected to the safety circuit, but that just depends on how you want it to work, or are there any other reason not to involve the driver alarms in the safety circuit?

    Ive seen an example on youtube of this driver hocked up, but not in differential connection mode, and not to a UB1 as I intend to use. Pending is not used, nor explained in that example neither.

    I've got it hooked up, connected to UCCNC and jogging back and forth, so that's something, but I still need to figure out the complete system setup, a bit worried Im missing something.

    Re: UB1 and stepperonline closed loop driver wiring

    So I understand this thread is a few months old, but here is a pdf link https://www.google.com/url?sa=t&sour..._C332y20bDa6nY

    This is not for the cl86y driver, but I think there is a good chance from the research I've done that these drivers are probably identical.

    I recently purchased the same motor driver combination and I'm waiting for the components to arrive. I'm still in a debate on what motion controller/Bob combination I plan to go with, but I will probably be using the above pdf document for assistance in wiring.

    To answer the question about what pend is, according to the manual it refers to positioning. So my guess is, that the encoder keeps track of positioning, and pend helps to send back signals from the controller to correlate that the position is matched. Which in turn might supply the driver with the input it needs to adjust current to keep the motor from losing steps/position.

    I'm about as far from knowing anything about the way electronics work, or how encoders or the closed loop that is programmed or implemented by these driver work. This is just the process of what I could understand and how it seems to work.

    I'm would be very pleased if someone who knows with absolute certainty to elaborate on the subject, possibly in a language the extremely uniformed could understand as well (example-me).

    Just a quick update, found some more information regarding what the pend function is used for. So I came across a few different thing but the consensus seems to be that it's used for verification of positioning. But it would be more for something like a robotic arm operation. Where each individual movement command was verified back to the control to make sure they agree. So basically not useful at all in multi axis simultaneous linking movements.

    Maybe useful for a swing arm type tool changer perhaps?

    Above Driver manual is broken, i find the following is the same as you share, but it can work:
