Multi axis positioning controller.
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 AJ71C21-S1 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 AJ71C21-S1
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 AJ71C21-S1 PDF datasheet . .
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. Output type: relay.
Output points: 8 points.
Load voltage: AC240/DC24.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 1.
Structured text language is a programming language that describes a program with a structured description of the text AJ71C21-S1 PDF 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 MITSUBISHI AJ71C21-S1 PDF catalog.
Mainly used for other programming languages more difficult to achieve the user program MITSUBISHI AJ71C21-S1 PDF catalog.
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.
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 annd the types of statements are simplified MITSUBISHI AJ71C21-S1 PDF catalog AJ71C21-S1 datasheet.
Structured text programming language features: the use of high-level language programming, you can complete the complex control operations,
Needd to have a certain level of computer knowledge and programming skills,
Higher requirements for engineering designers AJ71C21-S1 PDF datasheet . Poor visibility and operability.
