1. Characteristics of the output reactor:
1. It is suitable for reactive power compensation and harmonic control
2. The primary effect of the output reactor is to compensate for the influence of long-line distributed capacitance, and output harmonic current according to the press; 3. Effectively protect the Mitsubishi inverter and improve the power factor, which can resist the disturbance from the power grid and reduce the pollution of the power grid by the harmonic current generated by the rectifier unit.
The primary effect of the output reactor is to compensate for the influence of long-line distributed capacitance, and can reduce the noise of the Mitsubishi inverter by pressing the harmonics output of the Mitsubishi inverter. Some manufacturers also provide the maximum length of the wire that can be used to connect the motor with and without an output reactor.
2. Characteristics of the input reactor:
1. It is suitable for reactive power compensation and harmonic control
2. The input reactor is used to restrain the current impulse caused by the sudden change of grid voltage and the operation of overvoltage; The harmonic effect is filtered to control the distortion of the grid voltage waveform; 3. The spike pulse contained in the slippery power supply voltage, and the voltage defect that occurs during the commutation of the slippery bridge rectifier circuit; In the Mitsubishi inverter system with DC link, the DC reactor can effectively improve the power factor after the rectifier, and the power factor can be increased to 0.95 with proper coordination, and the DC reactor can make the inverter run smoothly and can constrain the short-circuit current, so the Mitsubishi inverter above 55kW produced by many manufacturers is supplied with DC reactor randomly.
3. Characteristics of DC reactor:
The primary purpose of the DC reactor is to limit the AC component superimposed on the DC current to a specified value, adhere to the continuous rectification current, reduce the current pulse value, make the inverter link run more stable and improve the power factor of the Mitsubishi inverter.

PLC Programming Recommendations – Mitsubishi PLC
1. When the PLC and the host computer (or touch screen) form a monitoring system, there are many hours on the screen that require "manual", "active" and other control forms (generally more than one). In the program, you can use the "MOV" command. For example, when selecting "manual", the constant 1 MOV will be changed to a ...

The role of Mitsubishi inverters
1. Overvoltage maintenance
The output of the motor inverter has the function of voltage detection, and the inverter can actively adjust the output voltage so that the motor does not bear the overvoltage. Even if the output voltage adjustment fails and the output voltage exceeds 110% of the normal voltage, the inverter will stop to maintain the motor.
