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 does not exceed the power supply voltage. The
maximum output voltage can be changed within the setting range. However,
the pulse voltage value of the inverter output side voltage remains unchanged
at about
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
(30°C for the totally enclosed structure) with the Pr. 72 (PWM frequency
selection) value set to 2kHz or higher.
7. The type code of the dirt-protection structure series ends with C.
