IGBT temperature (hardware)

Vacon · NX Liquid-Cooled Drive

¿Qué significa 31 ?

The IGBT Inverter Bridge overtemperature protection circuit has detected an excessively high short-term overload current, leading to a hardware-level temperature fault.

Causas comunes

  • IGBT temperature sensor failure (hardware fault).
  • Overheating detected on the IGBT module.
  • IGBT temperature exceeding critical threshold (P1-20).
  • Poor heatsink contact or insufficient cooling.
