*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 of 75K or higher with a value larger than 2kHz set in Pr. 72 PWM frequency selection, the rated output current is the value in

parentheses.

*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. With the dedicated external brake resistor FR-ABR-H (option), the 0.4K to 7.5K and 11K to 22K will achieve the performance of 100% torque/10%ED and

100% torque/6%ED respectively.

*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)
