MITSUBISHI FR-A7NS Instruction manual FR-A7NS communication function Manual

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 FR-A7NS Instruction manual FR-A7NS 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 high price can be omitted FR-A7NS Instruction manual.
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.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve FR-A7NS Instruction manual. Power: 37kw.
Voltage: 200V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 11kw.
SLD converter rated current: 25.0A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. MITSUBISHI inverter FR-L740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 18.5KW.
Integration of the three works the core technology, the outstanding performance of reeling, release the high cost of bright light.
Wide range of professional use and advanced control.
Professional built-in function to ensure the constant material tension, suitable for the application of prinnting and packaging industry FR-A7NS Manual .
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 operration of textile machinery equipment,
The spinning quality and production efficiency are improved FR-A7NS Manual . The application of textile machinery and equipment.
