Hi Sriram_K, If you move the Z-axis controller cable to the X-axis or Y-axis, configure the ClearPath High-Level FeedBack (HLFB) outputs identically on all axes, and the shutdown seems to follow the cable, then the issue is likely due to a wiring/configuration issue at the controller. As you troubleshoot this issue further, I recommend using Teknic’s Motor Setup Program (MSP) to help identify the issue (the software is free to download from Teknic’s website: https://teknic.com/products/clearpat...support-sd-dc/). You can run the MSP software even while the Acorn controller sends Step & Direction signals to the ClearPath motors, so you can monitor the state of the motor’s HLFB output in real time.

For more detailed support and troubleshooting, please contact Teknic directly at https://teknic.com/contact/ or give us a call at 585-784-7454.
