Hi arogers1987,
I’m an applications engineer at Teknic and I came across your post yesterday. First of all, I’m sorry to hear about the difficulty resolving this issue. While I’ve never used a UC300Eth before, I, or one of my colleagues, may be able to help you wire the ClearPath HLFB output to it. We’re happy to help sort out ClearPath wiring issues, but we probably can’t offer much when it comes to using the UC CNC software (you can view example wiring schematics on page 49 of the ClearPath manual located here:
https://www.teknic.com/files/downloa...ser_manual.pdf). In reading this forum though, there appears to be a number of friendly, knowledgeable people here that can help with the controller and software configuration.
I also wanted to mention that mactec54’s description of the HLFB output and his assertion that you can operate your ClearPath motors without wiring to the HLFB are both technically correct. That said, running without monitoring the HLFB output (i.e. not using it as an “alarm” input to your board) can lead to other problems. For example, I’ve seen cases–in an “HLFB unmonitored” machine–where one motor experienced a safety-related shutdown, and all the other motors continued the job because the system had no way of knowing about the one that shut down. This situation lead to a crash, resulting in a broken machine tool, a damaged work piece, and damaged mechanics (which were expensive and time consuming to fix).
Ideally, your ClearPath motors would be wired such that if one motor experienced a shutdown, the controller would receive an alert and immediately turn off the enable signal to all of the motors, and/or remove motor power, depending on your system’s features and capabilities. By wiring all of your HLFB outputs in series, as you described earlier in this thread, it sounds like that’s your strategy. I’d encourage you to stick with it if at all possible.
Please feel free to reach out to Teknic by calling 585-784-7454, or send us a contact request if we can help:
