Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 185KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment MITSUBISHI FR-A8NCE FR-A8NCE
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit.
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI FR-A8NCE. MITSUBISHI inverter FR-L740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 2.2KW.
Integration of the three works the core technology, the outstanding performance of reeling, release the high cost of bright light MITSUBISHI FR-A8NCE.
Wide range of professional use and advanced control.

Fusion application of the tension products of MITSUBISHI by inverter.
Suitable for tension control of high precision cable and material processing occasions.
Professional function to ensure the safe operation of textile machinery equipment,
The spinning quality and production efficiency are improved. The application of textile machinery and equipment. MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.75KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation. To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and highh price can be omitted FR-A8NCE.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study FR-A8NCE.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve.
