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 MR-J4-10A1-RJ 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. Output points: 64 points.
Output voltage and current: 24V ~ 0.2A/1 DC5 point.
2A/1 common end.
OFF leakage current: 0.1mA.
Response time: 1ms.
32 points and 1 common ends.
Leaky type.
40 pin connector.
With heat protection.
With short circuit protection.
With the surge absorber.
Ultra high speed processing, production time is shortened, better performance.
As applications become larger and more complex, it is necessary to shorten the system operation cycle time.
The operation period can be shortened by the super high basic operation speed 1.9ns.
In addition to achieve in the past with the control of single-chip high-speed control,
The system performance can be improved by reducing the total scan time,
To prevent any possible performance bias.
Convenient processing of large capacity data.
In the past can not achieve the standard RAM and SRAM card file register area of continuous access,
The boundary of each area should be considered in programming.
The SRAM 8MB extension card is installed in the high speed universal QCPU,
Standard RAM can be used as a continuous file register,
Capacity up to 4736K words, thus simplifying the programming.
Thus, even if the memory space of the soft element is insufficient,
Can also be installed by the expansion of SRAM card, easy to extend the file register area.
The address register is extended to 32 bits, which can be programmed to go beyond the traditional 32K word,
And to achieve the extension to the file register to all regions of the file register.
In addition, the processing speed of the index modification plays an important role in the efficient operation of structured data (array),
The speed has been improved.
When the index is used to modify the program repeatedly (e.g. from FOR to NEXT), the scan time can be reduced.
With the help of sample tracking function, the starting time is shortened
By using the sampling and tracking function, it is convenient to analyze the data when the fault occurs,
Testing procedures for the time, etc., can shorten the time of failure analysis and start-up time.
In addition, the multi CPU system also helps to determine the data transceiver time between the CPU module.
Can be used to analyze the data collected by programming tools,
In the form of charts and trend charts, the data changes of the bit soft element and the word soft element can be easily displayed.
And the sampling tracking results can be stored in LogViewer GX form CSV,
By recording data display and analysis tool LogViewer GX to display.
