Provided the car is running normally on Inspection operation and is drawing normal current,
perform the following test to verify the drive electronic motor overload protection is correctly
set to protect the motor from overload conditions:
1. Verify LF.08 (Electronic Motor Protection) is set to ON.
2. Note (write down) the value of LF.09 (Electronic motor protection current). This value
must be equal to LF.12.
3. Lower the value of LF.09 to 20% of the noted setting (LF.09 x 0.20).
