Possible Causes

Incorrect motor wiring sequence on CAME control board, Faulty motor capacitor (for single‑phase motors), Internal inverter fault on control unit, Loose motor terminal connections

How to Fix / Troubleshooting

Safety first: Isolate mains power before touching motor wiring. Capacitors can retain charge; discharge safely.

Steps:

  • Inspect motor terminals: Open the motor head or control box and check that all motor wires are firmly connected to the labeled terminals (e.g. U/V/W or M1/M2/COM).
  • Check capacitor: On single‑phase CAME motors, locate the run capacitor. Look for bulging, leaks, or burn marks. Replace with the same µF rating if suspect.
  • Verify wiring order: For 3‑phase motors, ensure the phase order matches the CAME wiring diagram. Incorrect order can cause wrong direction or inverter errors.
  • Reset control unit: Power down for 1–2 minutes, then power up and re‑run the travel learning procedure.

If E8 persists, the inverter section of the control board or the motor windings may be faulty and require professional testing.
