Axis of control: 2.
A1SD71-S2 is a linear interpolation of the pulse sequence output type positioning control module,
The stepper motor is suitable for the servo motor.
The fastest positioning speed up to 200Kpps, positioning range 1-16252928 pulse.
According to the specific application setting positioning unit,
If the number of pulses, mm, inches or degrees, but also to provide compensation to improve the positioning accuracy A1SJ72T25B datasheet A1SJ72T25B Output type: transistor drain.
Output points: 64 points.
Load voltage: DC12/24.
Load current: 0.1A.
Connection mode: terminal row.
Common public end points: 32.
Structured text language is a programming language that describes a program with a structured description of the text A1SJ72T25B datasheet.
It is a programming language similar to a high level language. In large and medium
Structured text is often used to describe the relationship between the various variables in the control system based on the PLC system.
Mainly used for other programming languages more difficult to achieve the user program.
The structured text programming language uses the computer description method to describe the various kinds of relations between the various variables in the system,
Complete the required function or operation A1SJ72T25B datasheet.
Most PLC manufacturers use structured text programming language similar to BASIC language, PASCAL language or C language and other advanced languages,
But in order to be convenient, the expression methods of the statement and the types of statements are simplified.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Need to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers. Poor visibility and operability. Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Optical data communication line function (GI cable).
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 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.
User program storage capacity: it is a measure oof how much the user application can store the number of indicators A1SJ72T25B PDF datasheet.
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 llogical operation instructions each account for 1 words A1SJ72T25B PDF datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
