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 230V.
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
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
FR-D720S-008SC and 014SC.
The power supply capacity varies with the value of the power supply side inverter impedance
(including those of the input reactor and cables).
