*1 The applied 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 of 75K or more with a value larger than 2kHz set in [Pr. 72 PWM frequency selection], the rated output
current is the value in parenthesis.
*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
the power supply.
*6 200V: When FR-ABR (option) is connected, 150% torque 10% ED for 0.4K and 0.75K, 100% torque 10%ED for 1.5K to 7.5K,
100% torque 6%ED for 11K to 22K.
400V: When FR-ABR-H (option) is connected, 15% torque 10% ED for 0.4K to 7.5K, 100% torque 6% ED for 11K to 22K.
*7 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input
reactor and cables).
*8 When the hook of the inverter front cover is cut off for installation of the plug-in option, protective structure of the inverter
changes to an open type (IP00).
*9 FR-DU07 : IP40 (except for the PU connector)
