Mitsubishi Inverter Family FR-A700 Series

Mitsubishi FR-A700 Series

Features

• Pursuing the best performance 

High-accuracy, high-response speed control using vector control is possible with a general-purpose motor without encoder. (200% 0.3Hz (3.7K or lower), with real sensor less vector control). Torque control and torque limit under speed control is possible. Full-scale vector control is possible by using this inverter with a motor with encoder. (when using optional FR-A7AP or A7AL) in addition to zero-speed control and servo lock, torque control and position control are available with this general-purpose inverter. The speed command response is improved. (Speed response 300rad/s, speed control range 1:1500 (with model speed control).  The torque fluctuation caused by changes in the motor temperature is reduced. (with adaptive magnetic flux observer having +5% repeated torque accuracy). The speed control again and position loop again do not need to be adjusted. (when simple again tuning is set.)

• Improved reliability and easy maintenance 

The lives of the cooling fan and capacitor have been extended. Using the self-diagnous function, the part warning can be output and the degree of deterioration can be monitored prevent malfunction. The removable control terminal block and the cooling fan cassette make it easy to replace.  

• Environmentally friendly  

 The newly developed analyzer function of the FR Configurator vibrates the motor to analyze the resonance frequency of machine. The filter function is available to avoid machine resonances. Encoder expandability the power voltage and input circuit can be selected according to the encoder.
