    Faults are recorded in parameter menu 10.20 (latest fault) to 10.29
    (oldest fault). My manual does not show an R5 fault but does have “rS”
    could that be what your display is showing?

    Ok Homer, the parameters that store the faults (10.20-10.29) are “READ ONLY” so they can NOT be changed. So you have to correct the issue instead. The rS fault is an Autotune fault “failure to measure resistance during Autotune” the drive was trying to test the motor but did not see it. Check your motor connections and make sure you get continuity phase to phase at the drive’s motor terminals. If you have anything between the motor and drive, check connections and at the motor junction box.
