| Fault | Name | Cause & Remedy |
|---|---|---|
| Err 3 | Overcurrent | Check for output short circuit or undersized drive. Increase acceleration ramp (Pr 0.03). |
| Err 7 | Overvoltage | Regenerative load without braking resistor, or deceleration too fast. Add braking resistor or extend decel ramp. |
| Err 4 | Undervoltage | Supply voltage below threshold. Check incoming supply and verify stability under load. |
| Err 15 | Drive overtemperature | Heatsink overheated. Check ambient temp (max 40°C), clean filter, verify fan operation. |
| Err 23 | Motor overtemperature | PTC thermistor tripped or I²t limit exceeded. Check for mechanical jam, verify motor cooling. |
| Err 46 | STO active | Safe Torque Off input opened. Check safety circuit wiring to STO terminals. |
| Err 27 | Supply loss | Input phase loss. Check supply connections and incoming fuses/breaker. |
| Err 1 | Phase loss (output) | Open circuit on output — motor cable disconnected. Check motor connection and cable. |
| Err 29 | Brake IGBT fault | Braking IGBT over-temperature. Check braking resistor connection and resistance value. |
