Remarks:
햲
The applicable motor capacityindicated is themaximum capacityapplicablefor useof the Mitsubishi 4-pole standard motor.
햳
The rated output capacity indicated assumes that theoutput voltageis 440V.
햴
The rated output current in theparenthesesapplies when low acousticnoise operation is to beperformed at an ambient temper aturehigherthan 40 °C withtheparameter
72 (PWM frequency selection) value set to 2 kHz or higher.
햵
The overload capacity indicatedin % is the ratio of theoverload current to the inverters rated current. Forrepeated duty, allow time for the inverter and motor to returnto or
below the temperature and 100 % load.
햶
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changedwithin the setting range. However, the pulsevoltage value
of theinverter output side voltage remains unchanged at about Ö2
that of the power supply.
햷
The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
