Load Loss

What does F015 mean?

The output torque current has fallen below a programmed minimum level (A490 [Load Loss Level]) for a duration longer than the set time (A491 [Load Loss Time]). This indicates that the mechanical load on the motor has been lost or significantly reduced, possibly due to a broken belt, coupling failure, or pump cavitation.

Complete Troubleshooting Guide

1. 1

   Visually inspect and verify the mechanical connections between the motor and the load (e.g., belts, couplings, gearboxes) for integrity and proper engagement.

2. 2

   Check the driven equipment for any failures, blockages, or conditions (like pump cavitation) that would cause a sudden reduction in mechanical load.

3. 3

   Review and adjust the A490 [Load Loss Level] and A491 [Load Loss Time] parameters to ensure they are appropriate for the application's normal operating and unloaded conditions.
