Note: 1. The applicable motor capacity indicated is the maximum capacity applicable when Mitsubishi 4- pole standard motor is used For A540K.

2.The rated output capacity indicated is based on for A540L.

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.

5.The power supply capacity changes with the values of the power supply side inverter impedance (including those of the input reactor and cables).

6.For use in Variable torque mode, refer to Pr. 570.

7.For inverter environmental conditions (including ambient temperature) please check page A-3.

8.Preliminary ratings.
