Note: 1. The applicable motor capacity indicated is the maximum capacity applicable
when a Mitsubishi 4-pole standard motor is used.
2. The rated output capacity indicated assumes that the output voltage is 440V.
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. The power supply capacity changes with the values of the power supply side
inverter impedances (including those of the input reactor and cables).
6. The rated output current in the parentheses applies when low acoustic noise
operation is to be performed at the ambient temperature higher than 40
°
C
with the Pr. 72 (PWM frequency selection) value set to 2kHz or higher.
