What does F063 mean?

A software-defined shear pin level (programmed in A486, A488 [Shear Pinx Level]) has been exceeded for a duration longer than the set time (A487, A489 [Shear Pin x Time]). This indicates a sustained excessive mechanical load, triggering a protective trip designed to prevent damage to the driven equipment, not necessarily the motor or drive.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Consider reducing the mechanical load or addressing any mechanical issues in the driven system.
