Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries,
In the country has been developed for decades of history, relatively speaking, is relatively mature industry, in the long run,
These industries also exist the needs of equipment upgrades A55B datasheet PDF catalog A55B PDF datasheet A55B
In this upgrading process, there will be some small, has been using relatively low-end products manufacturers are eliminated,
But there are also a lot of enterprises in the process of equipment renewal,
Re positioning the needs to find those that can meet their development plans,
Equipment suppliers to help them improve their productivity A55B datasheet PDF catalog A55B PDF datasheet. Special multi axis positioning controller for NSD servo system.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 points.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor A55B datasheet PDF catalog A55B PDF datasheet.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points. Input points: 32 points.
Voltage: AC200 ~ 240V.
Current: 12mA.
Response time: 25ms.
32 points / a common end.
38 point terminal station.
CE certification.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
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,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
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 chhanged with the change of the execution of the program A55B datasheet PDF catalog A55B PDF datasheet.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A55B datasheet PDF catalog A55B PDF datasheet.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
