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 FR-A740-220K-CHT PDF.
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-A740-220K-CHT 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-A740--220K-CHT PDF FR-A740-220K-CHT 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 FR-A740-220K-CHT PDF.
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. Input points: 4 points.
Weight: 0.02kg.
Function expansion board is used in the FX3SA, FX3S, FX3GA, FX3G, FX3GE on the small number of input and output extension of the product,
Can be built into PLC MITSUBISHI TECHNICAL MANUAL. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 15KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment MITSUBISHI TECHNICAL MANUAL.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the supper low speed region without the need of the encoder MITSUBISHI TECHNICAL MANUAL FR-A740-220K-CHT TECHNICAL MANUAL.
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequuency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc FR-A740-220K-CHT Manual . ) and torque control.
