*1
The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard
efficiency motor.
To drive a Mitsubishi Electric high-performance energy-saving motor, use the 0.75K inverter for a 1.1 kW motor, or 2.2K inverter for a
3 kW motor.
*2
The rated output capacity is the value with respect to 230 V output voltage.
*3
The percentage of the overload current rating is the ratio of the overload current to the inverter's rated output current. For repeated
duty, allow time for the inverter and motor to return to or below the temperatures under 100% load.
*4
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the
setting range. The maximum point of the voltage waveform at the output side of the inverter is approximately the power supply voltage
multiplied by2.
*5
The amount of braking torque is the average short-term torque (which varies depending on motor loss) that is generated when a motor
decelerates in the shortest time by itself from 60 Hz. It is not continuous regenerative torque. The average deceleration torque
becomes lower when a motor decelerates from a frequency higher than the base frequency. The inverter is not equipped with a built-
in brake resistor. Use an option brake resistor for an operation with large regenerative power (not available for the FR-E820-
0008(0.1K) and FR-E820-0015(0.2K)). The brake unit (FR-BU2) can be also used.
*6
The power supply capacity varies with the value of the input power impedance (including those of the input reactor and cables).
*7
The value in parentheses is the rated output current when the low acoustic noise operation is performed with the surrounding air
temperature exceeding 40°C while 2 kHz or higher value is selected in Pr.72 PWM frequency selection.
*8
The rated input current is the value at a rated output voltage. The input power impedances (including those of the input reactor and
cables) affect the value.
*9
Connect the DC power supply to the inverter terminals P/+ and N/-. Connect the positive terminal of the power supply to terminal P/+
and the negative terminal to terminal N/-.
When the energy is regenerated from the motor, the voltage between terminals P/+ and N/- may temporarily rise to 415 V or more.
Use a DC power supply resistant to the regenerative voltage/energy. When a power supply that cannot resist the regenerative voltage/
energy is used, connect a reverse current prevention diode in series.
Powering ON produces up to four times as large current as the inverter rated current. Prepare a DC power supply resistant to the
inrush current at power ON, although an inrush current limit circuit is provided in the FR-E800 series inverter.
The power capacity depends on the output impedance of the power supply. Select a power capacity around the AC power supply
capacity.
