MITSUBISHI A73CPU-S3

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 A73CPU-S3 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 A73CPU-S3.
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 A73CPU-S3. Drive unit 200VAC/400VAC level.
MITSUBISHI motor general AC servo amplifier MELSERVO-J3 series.
Need conversion unit MR-J3-CR55K4) supporting the use of.
Rated output: 37kw.
Interface type: SSCNET type III fiber communication.
Special features: integrated driver security.
Power specification: three phase AC400V.
High speed serial communication between the SSCNET and the servo amplifier by using the fastest up to 0.44ms communication cycle,
A fully synchronous control system can be constructed.
It is only necessary to insert the special optical fiber into the joint to form SSCNET III network, which greatly reduces the wiring work and reduces the possibility of false wiring.
Due to thee adoption of the optical ffiber communication, the anti noise ability can be greatly improved and the long distance wiring of 50 meters (maximum 800 meters x 16 axes) can be realized A73CPU-S3.
A servo amplifier to meet the full closed loop control function MR-J3-B-RJ006.
Suitable foor mechanical servo optimization and adjustment!
More advanced optimization adjustment function and control function to maximize mechanical properties A73CPU-S3.
