L6-13: Motor Underload Protection Selection
Sets Motor Underload Protection (UL6) based on motor load and determines whether the level of L6-02 refers to fbase or
fmax.
Selects the operation of underload detection UL6. Underload is detected when the output current falls below the underload
detection level defined by L6-14 and L2-02.
