*1. The applied 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. 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.
*4. The maximum output voltage does not exceed the power supply voltage. You can set the
maximum output voltage to any value below the power supply voltage. However, the
pulse voltage value of the inverter output side voltage remains unchanged at about
that of the power supply.
*5. The power supply capacity varies with the value of the power supply side inverter
impedance (including those of the input reactor and cables).
