Teknic Clearpath SDSK wiring to 7i96s

I worked on it a bit more. It's missing 2x 24v NPN-NC probes, and I think with 24v common supplying the sensors and hlfb circuit, I may be able to daisy-chain the hlfb after all. Still confirmation there.

Hi fully_defined,

I'm an engineer with Teknic and came across your post. While we're not familiar with the exact board and pinout, the ClearPath wiring makes sense. (Good suggestions PCW)

If you encounter any problems or have other questions, please reach out directly at 585-784-7454 or teknic.com/contact/.

Would you mind taking a second look? I have updated this post, and the image at the top reflects my current understanding of how to wire this. I think the only question relevant to you now is: now that I am powering the field inputs with 24v, can I get away with daisy chaining hlfb to save on inputs? I thought I recalled hearing that this is the preferred Teknic method, but I can't find anymore where I read that.

In this post, the OP said he figured it out and then the thread went cold. People had more questions that were unfortunately never addressed again: www.forum.linuxcnc.org/10-advanced-confi...fb-mesa-7i76e#114031

The purpose of this thread (the one you're reading now) is to create a definitive resource for myself and others to refer to later.

With daisy chaining of HLFB. There's a decent chance that I have erred in some way setting this up. Please take a look!

Hi fully_defined,In reviewing your drawing, we have a few suggestions and clarifications:

• For the HLFB output: As long as the circuit has sufficient voltage (24VDC will work) and current, HLFB can be daisy chained as shown in our photo below. You’ll need to configure each motor to use the HLFB mode “Servo On”. In this configuration, if any individual motor has its HLFB go low, the “fault input” at the controller would also go low.
• For the Enable input: All of the motors can be enabled together as shown. Note that with this configuration, you won’t be able to individually enable or disable any of the axes.
• For ground lines: As it’s not stated in the schematic, note that you’d want to run all of the ground lines back to the controller and connect them together at the controller (you wouldn’t connect the grounds together at the motors or elsewhere in the cable run).
