Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor MITSUBISHI INSTRUCTION MANUAL. )
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) "MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 185KW MITSUBISHI INSTRUCTION MANUAL.
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic MITSUBISHI INSTRUCTION MANUAL.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
Frequency converter is aa power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions FR-F740-00023 to 12120-NA Manual.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency,
The equipment to the power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, which is mainly used iin the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FR-F740-00023 to 12120-NA INSTRUCTION MANUAL.
The general inverter is 1520 times inverter price.
The main device called "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter FR-F740-00023 to 12120-NA Manual. "
