 L1-02 Motor Overload Protection Time
Setting Range: 0.1 to 5.0 Minutes
Factory Default: 1.0 Minutes
The L1-02 parameter will set the allowed operation time before the oL1 fault will occur
when the drive is running at 60 Hz and 150% of the motor’s full load amp rating (E2-01).
Adjusting the value of L1-02 can shift the set of oL1 curves up the Y-axis of the diagram
