To operate under load trip properly, a load tuning (AP2-01 Load Tune) must be performed in
advance. If you cannot perform a load tuning, manually set the load fit frequencies (AP2-02
Load Fit Lfreq
–AP2-10 Load Fit Hfreq). The Under Load protection does not operate while the
Energy Save function is in operation.

When the code value is
set to ‘8 (FAN Warning)’, the fan error signal is
output and operation continues. However, when the inverter’s inside
temperature rises above a certain level, output is blocked due to
activation of overheat protection.
6.3.2 Low Voltage Fault Trip
When inverter input power is lost and the internal DC link voltage drops below a certain
voltage level, the inverter stops output and a low voltage trip occurs.
