*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 220V for 200V class and 440V for 400V class.
*3 When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency will automatically decrease
if the output current of the inverter 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
that of the power supply.
*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 When the hook of the inverter front cover is cut off for installation of the plug-in option, the inverter changes to an open type
(IP00).
*8 FR-DU07 : IP40 (except for the PU connector)
