Countermeasure against harmonics

When the high power factor converter is installed, you can use the conversion coefficient of K5 = 0 for calculation. In accordance with the harmonic suppress... More Details >>

Interval of next power ON

The instantaneous power failure error occurs when the power is turned ON instantaneously (within 100 ms) after the power is turned OFF. When the motor is coa... More Details >>

Amount of heat generated

The amount of heat generated by the FR-E500 series inverter is registered in the Mitsubishi Electric FA Global Website Member's page. Refer to the technical ... More Details >>

Operation of the motor with a brake

For the general-purpose inverter, the motor stop cannot be detected accurately because the actual motor speed from a motor is not input. In general, the RUN ... More Details >>

Frequency display

When Advanced magnetic flux vector control (Pr.80, 81) is used, the machine speed constant is controlled. The inverter calculates the motor slip and compensa... More Details >>
