| Symptom | Likely Fault | Diagram Step | |---------|--------------|---------------| | No output, no fault code | 15V supply missing | Check pin 1 on CN1; trace back to isolated DC-DC converter. | | Random overcurrent (nFAULT low) | Noisy bootstrap capacitor | Locate Cboot near each gate driver; replace with low-ESR type. | | Motor runs rough, unbalanced | One current sensor failed | Measure pin 12 & 13 during low-speed run; should see sine waves. | | Module heats up at idle | Shoot-through in one phase | Check deadtime circuit; measure gate signals with scope. | | PFC error on host display | DC bus voltage reading wrong | Probe VDC_BUS (pin 11). Should scale linearly with actual DC voltage. | Standard connection diagrams for these frames typically show
