Motor underload

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.
