| Symptom | Likely Cause | Diagnostic Step | Remedy |
|---------|--------------|------------------|--------|
| No power LED | Power supply absent/incorrect polarity | Measure voltage at the DC‑IN pins (should be 24 V ±10 %). | Re‑connect correct supply, add fuse if missing. |
| Motor stalls, encoder counts frozen | Driver over‑current protection triggered | Check driver fault register via controller.read_faults(). | Reduce load, increase current limit, verify wiring. |
| Ethernet timeout | IP conflict or cable fault | Ping the controller IP; use a known‑good CAT‑5e cable. | Assign a unique static IP or enable DHCP. |
| Unexpected jitter in position | Encoder ground loop or EMI | Observe encoder signal on an oscilloscope; look for noise spikes. | Use shielded twisted pair, add ferrite beads, improve grounding. |
| E‑stop does not halt motion | E‑stop wiring polarity reversed | Verify E‑stop logic in firmware (controller.set_estop_polarity()). | Re‑wire or change polarity setting. |
| Firmware update fails | Bootloader not entered (USB/ETH not recognized) | Hold BOOT button while powering on, then reconnect. | Ensure correct boot mode; use the provided bootloader utility. |
| Fault log fills up quickly | Repeated over‑temperature or undervoltage events | Read fault log (controller.read_fault_log()). | Check ambient temperature, improve cooling, verify supply regulation. | and LabVIEW bindings
Understanding JUFE-384
Because JUFE‑384 can maintain deep circuits with low error, algorithms that were previously “too deep” for NISQ devices—such as quantum phase estimation with > 30 bits of precision—become tractable.
