*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 01440 or higher with a value larger than 2kHz set in Pr. 72 PWM frequency selection, the rated output current is the value in
parenthesis.
When operating the inverter with the carrier frequency set to 3kHz or more with LD or SLD set, 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
*6. With the dedicated external brake resistor FR-ABR-H (option), the 00015 to 00170 and 00230 to 00440 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)
*10. When LD or SLD is selected for the FR-A720-01100-NA, install a DC reactor (FR-HEL-H90K).
