Note: 1. The applicable motor capacity indicated is the maximum capacity applicable when Mitsubishi
4-pole standard motor is used.
2. The rated output capacity indicated assumes that the output voltage is 220V for 200V class and
440V for 400V class.
3. The overload capacity indicated in % is the ratio of the overload current to the inverter's rated
current. For repeated duty, allow time for the inverter and motor to return to or below the
temperatures under 100% load.
4. The maximum output voltage cannot exceed the power supply voltage. The maximum output
voltage may be set as desired below the power supply voltage. However, the crest value of the
inverter output voltage remains unchanged from the DC bus voltage.
5. Short duration rating 5s
6. The power supply capacity changes with the values of the power supply side inverter impedances
(including those of the input reactor and cables).
7. The open type (IP00) is used when the inboard option is fitted after removal of the option wiring
port cover.
