Tab. A-1: Specifications
The applied motor capacity indicated is the maximum capacity applicable for use of the
Mitsubishi 4-pole standard motor.
The rated output capacity indicated assumes that the output voltage is 230 V.
Setting 2 kHz or more in Pr. 72 "PWM frequency selection" to perform low acoustic noise operation
with the ambient temperature exceeding 40 °C, the rated output current is the value in parentheses.
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.
If the automatic restart after instantaneous power failure function (Pr. 57) or power failure stop
function (Pr. 261) is set and power supply voltage is low while load becomes bigger, the bus
voltage decreases to power failure detection level and load of 100% or more may not be available.
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 2 that of the power supply.
The braking torque indicated is a short-duration average torque (which varies with motor loss)
when the motor alone is decelerated from 60 Hz 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 FR-E720S-008SC and 015SC.
The power supply capacity varies with the value of the power supply side inverter impedance
(including those of the input reactor and cables).
