current for 1 minutes, the alarm indicates motor overload fault; 150% * (P9-01) * motor
rated current for 60 minutes, then the alarm indicates motor overload.
The user needs to set the value of P9-01 correctly according to the actual overload capacity
of the motor. The parameter is too large to lead to overheating of the motor without
warning and become dangerous.

This function is used to give a pre-warning signal to the control system through the HDO
before the overload fault protection of the motor. The warning coefficient is used to
determine how warning is performed before the overload protection of the motor. The
greater the value, the smaller the amount of early warning.
When the output current of the inverter is larger than that of the overload reverse time
curve x P9-02, the multi-function terminal HDO of the inverter outputs "the motor
overload alarm" of ON signal.

When the frequency inverter chooses to fault reset automatically, it is used to set the
number of automatic reset. If more than this value, the inverter remains in a state of faulty.
