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 AJ65SBTB1-32DT
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 AJ65SBTB1-32DT. Input points: 32 points.
Voltage: DC48/60V.
Current: 3/4mA.
Response time: 20ms.
8 points / a common end.
Negative utility.
38 point terminal station.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh AJ65SBTB1-32DT.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read .
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Undder the premise of meeeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC AJ65SBTB1-32DT.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation AJ65SBTB1-32DT.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
