*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 440V.
*3
When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency automatically
decreases if the inverter output current exceeds the value in parenthesis of the rated current. This may cause the
motor noise to increase.
*4
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.
*5
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
*6
The power supply capacity varies with the value of the power supply side inverter impedance (including those of
the input reactor and cables).
