Motor Overtemperature

Vacon · NX Liquid-Cooled Drive

What does 16 mean?

The AC drive's internal motor temperature model has detected that the motor is overheating. This condition typically arises when the motor is subjected to sustained overloading, causing its winding temperatures to rise beyond acceptable limits.

Common Causes

  • Motor thermal overload protection tripped.
  • Motor winding temperature sensor fault (P0206).
  • Excessive motor current draw.

Repair Steps & Checklist

  1. 1

    Reduce the mechanical load on the motor to ensure it operates within its nominal operating current and torque limits.

  2. 2

    If no motor overload is apparent, review and adjust the motor temperature model parameters within the drive to ensure they accurately reflect the motor's thermal characteristics.
