(1) 3-phase 200V power supply
*1. The applicable motor capacity indicated is the maximum applicable capacity when a
Mitsubishi 4-pole standard motor is used.
*2. The rated output capacity indicated assumes that the output voltage is 230V.
*3. The % value of the overload capacity indicates 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 PWM pulse voltage value of the inverter output side voltage remains
unchanged at about that of the power supply.
*5. The power supply capacity changes with the values of the power supply side inverter
impedances (including those of the input reactor and cables).
