MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 55KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment .
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit MR-J3-DU45KBS4
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MR-J3-DU45KBS4. Multi axis positioning controller.
Program capacity: Max 60K step.
Input / output points: 1920 points.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of MR-J3-DU45KBS4.
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
Light emitting diode two: the input of a photo coupler and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
Photoelectric three levels: in the light of the light signal conduction, the degree of light signal and the intensity of the light signal.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler.
Useer program storage cappacity: it is a measure of how much the user application can store the number of indicators MR-J3-DU45KBS4.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General lloggical operation instructions each account for 1 words MR-J3-DU45KBS4. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
