5. Troubleshooting “67 top” common issues

| Problem | Fix | |-----------------------------|----------------------------------------------------------------------| | No motion / missed steps | Check 24V external supply; reduce acceleration; increase step pulse width (5–10 µs). | | Spindle not starting | Measure 0–10V output; set VFD to external control; check relay. | | Limit switch triggers randomly | Use shielded cables; set software debounce to 10–20 ms. | | Card not detected | Re-seat PCI card; disable PCI power management in BIOS; test on Win7 32‑bit (older cards). |
