Three-phase 200V power supply
Three-phase 400V power supply
∗1 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
∗2 The rated output capacity indicated assumes that the output voltage is 230V for three-phase 200V class and 440V for three-phase 400V class.
∗3 The % value of the overload current rating indicated 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. However,
the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.
∗5 The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz in the shortest
time and is not a continuous regenerative torque. When the motor is decelerated from the frequency higher than the base frequency, the average
deceleration torque will reduce. Since the inverter does not contain a brake resistor, use the optional brake resistor when regenerative energy is large. A
brake unit (FR-BU2) may also be used. (Option brake resistor cannot be used for 0.1K and 0.2K.)
∗6 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
∗7 Setting 2kHz or more in Pr. 72 PWM frequency selection to perform low acoustic noise operation in the surrounding air temperature exceeding 40°C, the rated
output current is the value in parenthesis.
∗8 Connect DC power supply to terminal P/+ and N/-. Connect the plus side of the power supply to terminal P/+ and minus side to terminal N/-.
Since the voltage between P/+ and N/- may increase due to the regeneration energy from the motor and exceeds 415V temporarily, select the DC power
supply which can withstand the voltage/energy during regeneration. If using the power supply which can not withstand voltage/energy during regeneration,
insert diodes in series for reverse current prevention.
Although the FR-E700 series has the built-in inrush current limit circuit, select the DC power supply considering the inrush current at powering ON as the
inrush current four times of the rated inverter flows at powering ON.
Since the power supply capacity depends on the output impedance of the power, select the power supply capacity which has enough allowance according
to the AC power supply system capacity.
