*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.
*3. When operating the inverter of 02880 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 (option), the 00030 and 00050, 00080 to 00330, 00460 to 00900 will achieve the performance of 150%
torque/10%ED, 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).
When using the FR-A720-00900 with LD or SLD set, a wiring cover may need to be removed depending on the used wire size.
The protective structure is an open type (IP00) when a wiring cover is removed.
*9. FR-DU07:IP40 (except for the PU connector)
*10. Protective structure of SLD and LD rating of FR-A720-00900-NA is IP00 due to vending space.
The conduit plate needs to remove at SLD and LD.
*11. When LD or SLD is selected for the FR-A720-02150-NA, install a DC reactor (FR-HEL-75K).
