08-10=0:
Output phase loss detection is disabled.
08-10=1:
Output phase loss detection is enabled. Keypad shows "LF" when an output phase loss is detected and
the inverter output is turned off and the fault contact is activated.
Note:
The output phase loss detection is disabled when the output current is less than 10% of the inverter rated
current.

Overload protection for motors used in general purpose applications, motor load not to exceed
103% of the motor rated current for the motor to continue to run. If the load is greater than 150% of the motor
rated current, the motor will run for 60 sec before tripping on a motor overload condition. (Curve 1).
