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 MITSUBISHI FX3U-64MT/ES-A Manual FX3U-64MT/ES-A 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 MITSUBISHI FX3U-64MT/ES-A 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 MITSUBISHI FX3U-64MT/ES-A Manual. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 30KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
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 super low speed region without the need of the encoder.
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc.) and torque control. Max input / output points: 30 points.
Power supply voltage: DC24V.
Input points: 16 points.
Output points: 14 points.
Output type: Transistor (source).
Power consumption (W): 21.
Weight (kg):0.45.
Size (WxHxD) mm:100x90x75.
Positioning and pulse output functions: a PLC cell can output 2 point 100KHz pulses at the same time.
PLC is equipped with 7 special positioning instructions,
Including zero return, absolute or relative address expression and special pulse output control.
Host has 10 points (6I/4O), 14 points (8I/6O), 20 points (12I/8O), 30 points (16I/14O) of 4 types.
This type of PLC is mainly used in all of the digital input, digital output control point of the device.
Can be directly connected to the 220V city power, built-in 8K step EEPROM memory, no battery, easy too maintain FX3U-64MT/ES-A PROGRAMMING MANUAL.
The series transistor output (MT) of the PLC, can be output 2 100KHz pulse, direct drive servo or stepper motor.
The series PLC can not be brought with the expansion module, but can be installed by the BBD board to extend a small amount of I/O FX3U-64MT/ES-A PROGRAMMING MANUAL.
The series 1N through the installation of BD series PLC board, can achieve RS232, RS485, RS422 communication.
