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 MR-J4-11KB4-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. MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 11.0kw.
Interface type: SSCNET type III fiber communication.
Full closed loop control.
Power specification: three phase AC200V.
High precision and high response location control.
Full closed loop control can be realized by double feedback control method.
Dual feedback control can be performed between the servo motor encoder and the load side encoder.
MR-J3-B-RJ006 can be used in conjunction with a number of manufacturers of linear encoder,
Users can build the system according to their own accuracy requirements. ABS type linear encoder using serial interface,
No need to install the battery on the servo amplifier can easily build the absolute position detection system.
Flexible system configuration.
Can achieve higher load side positioning accuracy!RS-232:1 channel, RS-422:1 channel.
BASIC program mode (A3MCPU corresponding): BASIC console interface to use.
Sequential program mode (program controller CPU correspondence): non sequential computer connection interface and use.
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
