Model setting
Overload pre-alarm mainly monitors overload condition before overload protection of inverter. Overload pre-alarm level
defines the current threshold of overload pre-alarm action, and its set value is relative to the rated current of inverter.

Overload pre-alarm delay defines the delay time between the output current of inverter continuously exceeding the
amplitude of overload pre-alarm level (10.12) and the output of overload pre-alarm signal.
Notes:
By setting the parameters 10.12 and 10.13, when the output current of the inverter is greater than the overload
pre-alarm level amplitude (10.12), the inverter outputs the pre-alarm signal after delay (10.13), that is, the keypad displays
A–09.

When the input phase lose protection is selected to be valid and the input phase lose fault occurs, the inverter will
protect E-12 after the time defined in 10.16, and stop freely.

When the actual output current of the motor is greater than the rated current * [10.17], if the output phase failure
protection is valid, after a delay time of 5S, the inverter protection acts [E-13] and stops freely.
