Tab. A-2: 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 440V.
Setting 2kHz 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 parenthesis.
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.
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 power supply capacity varies with the value of the power supply side inverter impedance
(including those of the input reactor and cables).
