Motor thermistor over temperature

Danfoss · VLT Micro Drive FC 51

What does 11 mean?

The motor's thermistor input indicates an over-temperature condition, or the thermistor or its connection is disconnected. This provides direct thermal protection for the motor, signaling a critical overheating risk if not addressed.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Reduce the mechanical load on the motor and allow it to cool down before restarting.

  2. 4

    Ensure the drive's thermistor input parameter (e.g., 1-93 Thermistor Input) is correctly configured for the type of thermistor used.
