MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 2.2KW.
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 FX2N-4AD-TC 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. Memory card interface, serial interface.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust.
On-line debugging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on step by step.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be. "10BASE2.
Ethernet interface module capable of selecting the most suitable system and object device.
Support 100BASE-TX, can speed up the transmission speed. (QJ71E71-100)
Data communication can be performed between programmable controller CPU using special instructions.
Can use the HTTP protocol, through the Web browser on the PC access to the soft element of the programmable controller.
PC (Web) on the use of the communication program library and sample screen can be obtained by download services.
Can connect a number of programming tools to improve the efficiency of debugging.
Make use of e-mail function, through the mail server to send e-mail (ASCII format) and attachments (binary, ASCII and CSV format).
The KeepAlive function can be used to perform the existence of the object equipment inspection, and keep the connection in the open state.
This can be used to ensure connectivity and to quickly find errors.
Optimal network matching for application purposes and applications,
Seamless communication between different hierarchical systems.
Enhancing the ability of information communication through network.
This is also a major task in the field of automation.
Network environment provided by Q series
Is truly open & seamless.
Including based on universal ethernet,
Achieve easy management of the environment "IE Control CC-Link" controller network,
As well as in its management to achieve a high-speed, high-capacity transmission of the "IE Field CC-Link" field network.
Also including Japan''s first, to achieve the world standard,
And get the SEMI certification of the field network "CC-Link",
And inherited the design concept of the provincial distribution network CC-Link/LT".
And support sensor networks "AnyWire",
To enrich the lineup flexibility to integrate the various layers of automation network. "
