Stall prevention stop

What does E.OLT mean?

This stall prevention stop fault occurs if the inverter's output frequency drops to 1Hz and remains there for 3 seconds due to active stall prevention. It indicates a prolonged and severe overload condition on the motor, which can lead to motor and inverter stress if unaddressed.

1. 1

   Reduce the mechanical load on the motor to bring it within the inverter's capacity.

2. 2

   Review and adjust the Pr. 22 (Stall prevention operation level) setting to ensure it is appropriate for the application.
