L1-02: Motor Overload Protection Time
Setting Range: 0.1 to 5.0 Minutes
Factory Default: 1.0 Minutes
The L1-02 parameter sets the allowed operation time before the oL1 fault occurs when the
drive is running at 60 Hz and
150% of the full load amp rating (E2-01) 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.
