Type: MR-J_B series.
Rated output: 0.2KW.
Interface: standard.
Servo system according to the system structure can be divided into open loop servo system, closed loop servo system, semi closed loop system, compound control system.
The closed loop automatic control system with feedback is composed of a position detecting part, a deviation amplifying part, an executing part and a controlled object A1SD71-S7.
Servo system must have good controllability, high stability and high adaptability A1SD71-S7
Note that the control of the signal is good after the disappearance of the signal, can immediately stop the turn;
High stability is the torque with the increase of speed and uniform decline; adaptability is fast, sensitive, and ring state quality is good A1SD71-S7.
According to the types of servo drives are classified, there are three kinds of electric, hydraulic or electric hydraulic.
If the servo system is divided according to the function, then there is a measuring servo and power servo system;
Analog servo and power servo system; position servo and acceleration servo system.
The electric servo system can be divided into two categories: DC DC servo system and AC AC servo system based on the electrical signals A1SD71-S7.
AC AC servo system also has two kinds of asynchronous motor servo system and synchronous motor servo system. Motor: HA-MH type super small.
Power: 0.2kw.
Speed: 3000r/min.
Electric machine is a kind of electromagnetic device which can convert or transfer electric energy according to the law of electromagnetic induction.
In the circuit with the letter M (the old standard with D) said.
Its main function is to produce the driving torque, as a power source of electrical appliances or mechanical.
The generator is represented by the letter G in the circuit.
Its main function is to convert mechanical energy into electrical energy,
At present, the most commonly used, the use of heat, water and other power generator rotor to generate electricity. Enter points: 64 points.
Voltage: DC12/24V.
Current: 3/7mA.
Response time: 10ms.
32 points / a common end.
Cathode common.
40 pin connector.
High speed input.
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 A1SD71-S7.
The coontents 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 thhe adoption of centralized sampling A1SD71-S7.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
