■ L1-02: Motor Overload Protection Time
Setting Range: 0.1 to 5.0 min
Factory Default: 1.0 min
Parameter L1-02 determines how long the motor is allowed to operate before the oL1 fault occurs when the drive is
running at 60 Hz and at 150% of the full load amp rating (E2-01/E5-03) of the motor. Adjusting the value of L1-02 can
shift the set of oL1 curves up the y axis of the diagram below, but will not change the shape of the curves.
