Motor underload

Vacon · NXS NXP Drive

What does 17 mean?

The motor underload protection has tripped, indicating that the motor is operating with insufficient mechanical load or no load at all. This can be caused by a broken belt, pump cavitation, an uncoupled shaft, or a process anomaly. Operating in an underload condition can sometimes lead to drive instability or signify a mechanical issue that requires attention.

Complete Troubleshooting Guide

  1. 1

    Inspect the mechanical connection between the motor and its load (e.g., belts, couplings, pump impellers).

  2. 2

    Verify that the load is present and coupled correctly to the motor shaft.

  3. 3

    Adjust the underload protection parameters in the drive if the current load is normal for the application.
