Units: Overload pre-alarm detection
• 0: It is active all the time in running status.
• 1: It is active only at constant speed.
Tens: Action selection for overload pre-alarm
• 0: The inverter doesn’t alarm and continues operation when detecting an active overload signal.
• 1: The inverter alarms and stops operation when detecting an active overload signal.
Hundreds: Overload threshold selection
• 0: Ratio of load current to the motor’s rated current (alarm: motor overload “E0019”).
• 1: Ratio of load current to the inverter’s rated current (alarm: inverter overload “E0017”).
Thousands: Motor type selection
• 0: Standard motor. As the cooling effect of the standard motor deteriorates at low speed, the
inverter will automatically make regulation to the motor overload protection time.
• 1: Variable frequency. The cooling effect of the variable frequency motor is not affected by the
motor’s speed due to its forced cooling potential, the inverter will not automatically make
regulation to the motor overload protection time, as efficient motor cooling by an external motor
fan is assumed.
Ten thousands: Overload protection
• 0: Overload protection is enabled.
• 1: Overload protection is disabled.

F20.01 defines the current threshold for overload pre-alarm protection. The setting range is a
percentage value of the motor’s or the inverter’s rated current.
