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
a hot motor at 60 Hz and at 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.

Precautionary Notes on External Heatsink (IP00/Open Type Enclosure)
When using an external heatsink, UL compliance requires covering exposed capacitors in the main circuit to prevent injury
to surrounding personnel.
The portion of the external heatsink that projects out can be protected with the enclosure or with the appropriate capacitor
cover after completing drive installation. Use Table D.9 to match drive models with available capacitor covers. Order capacitor
covers from a Yaskawa representative or directly from the Yaskawa sales department.
