| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | Motor hums but doesn't spin | One winding is open; Contactor welded shut | Check continuity on U1/V1/W1 and U2/V2/W2. Replace contactor. | | Slow speed works, fast speed trips breaker | Incorrect voltage selection (e.g., 230V applied to 400V winding) | Verify nameplate voltage. Reconnect winding from Star to Delta if needed. | | Overheating at low speed | External cooling fan failed | The motor relies on the external fan. Replace or rewire the fan to run continuously. | | Random trips from PTC relay | Ambient temp too high; Overloaded at low speed | Measure actual motor current vs nameplate FLC. Clean dust from motor fins. | | Excessive vibration | Unbalanced load; Worn C3 bearings | Check coupling alignment. Replace bearings (use original C3 clearance). | | Symptom | Likely Cause | Solution |
The VTWIN environment offers several advanced features for its era, designed to simplify the development of complex machine-control interfaces: Reconnect winding from Star to Delta if needed
