Yaskawa iQpump Micro Quick Start - Manual (Page 105)

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.
