YASKAWA V1000 Technical Manual

Setting L1-01 = 2 selects a motor capable of cooling itself over a 10:1 speed range when running at 100% load. The oL1
function derates the motor when it is running at 1/10 or less of its rated speed.
Setting L1-01 = 3 selects a motor capable
of cooling itself at any speed — including zero speed — when running at 100%
load. The oL1 function does not derate the motor at any speed.
Setting L1-01 = 4 selects protection for a PM motor with variable torque.

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.
