MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
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 Q63B 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.
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 general purpose AC servo amplifier MR-J2 series.
Rated output: 2.0kw.
Interface: single axis positioning built-in type.
Voltage: three phase AC200V.
High response.
High precision positioning.
High level automatic tuning, can easily achieve gain settings.
Adopting adaptive vibration control and reducing vibration.
With a computer combination, using the software to achieve the best tuning.
Pulse sequence input (position, speed control), analog input (speed, torque control) two purposes.
Simple operation.
The socket is arranged on the front panel, and is convenient to connect.
Using the socket, wiring easy.
Setting method and J2Super with interchangeable. 4 channel analog input module.
A1S64AD analog input module can accept the voltage or current signal,
The built-in microprocessor converts these signals to binary values,
For the control program to enjoy.
