Motion control PLC medium

henzhen keda technology co., LTD., independent research and development of VEC - VA series motion controller, PLC type can also be referred to as the motion control integration. The KW - Multiprog programming tools, support the five kinds of iec61131-3 international standard programming languages, all the engineers familiar with PLC programming, almost don't have to learn can carry on the programming. VEC motion controller card has five axis interface, a main shaft interface, four servo axis interface, servo axis can be extended to 64 axis; Support the real-time multi-task control, with advanced and easy-to-use simulation tools, integrated rich motion control function block; Four servo axis movement control cycle is less than 1 millisecond. 
 
 
 
Areas of application: 
 
Applicable to the packaging industry, printing industry, textile industry, machine tool industry, all kinds of equipment of the construction industry. 
 
Technical features: 
 
(a) and standardized programming language 
 
Support the five kinds of iec61131-3 international standard programming languages, all the engineers familiar with PLC programming, almost don't have to learn can carry on the programming. There are the following features: 
 
1. In the same programming interface to support three kinds of graphical programming language 
 
Ladder diagram (LD), functional diagram block (FBD) and sequential function chart (SFC) of the three graphical programming language can be mixed programming at the same time, this can be three kinds of graphical language organic unifies in together, thus the advantage of flexible use of various language programming. 
 
2. The combination of traditional programming languages and graphical language 
 
Instruction list (IL) and structured text (STD) because the two languages is a text programming language, so in an interface can only support one. But can be used to define function block (FB) the method of combining textual and graphical languages. Written in STD language complex algorithms, for example, the reserved entrance parameters and export, and packaging as the function block, it can make calls in the graphical language. 
 
(2), real-time multitask control 
 
VEC - VA motion controller to control engine supports real-time multitasking function, support a total of four types of tasks: the Default Task, Cyclic, Event Task, the System Task. Engineers can according to the complex task to achieve, it divided into has the right to limit the task level for processing; Complex control system often requires multiple cycles, each cycle can run different rates. In this way, the whole control system of the optimized operation, and has good real-time performance. The demand response fast closed loop control system, especially a favorable tool. 
 
(3), advanced and easy-to-use simulation tools 
 
1. This software is equipped with the software simulator, in the case of not connect controller hardware can be used to simulate the input and output of IO points. In IO logic control related application start process, greatly improve the development efficiency of developers. 
 
2. This software integrates the powerful logic analyzer, to online record discontinuous or the state of the logic variables and to be shown in the chart by logic analyzer, can evaluate whether the program according to the expected to perform. 
 
(4), the rich motion control function block 
 
Support VEC motion controller PLC open standard motion control function block and crosscutting, feed, labeling, heavy load of non-standard modules. Make the system more easily execute point-to-point motion, zero, electronic gear, electronic CAM, velocity stack functions. 
 
1. The point-to-point movement function module support 4 power, is the speed of the cosine curve optimization, will keep servo axis in the process of motion acceleration continuously adjustable, thereby minimizing mechanical shock. 
 
2. 5 integrated square, is cosine calculate real-time electronic CAM, such as the function block, in the corresponding applications users do not have to set up electronic CAM table can be realized servo curve motion computation period up to 1 ms. (applications: front paper, labeling machine, machine, etc.), just call the function block application personnel, and write the corresponding external IO logic and the system program can be completed. 
 
3. The built-in round cutting, after cutting and other special function blocks. Crosscutting industry system programming difficulty is greatly simplified. Application personnel need to call the module, and write the corresponding external IO logic and the system program can be completed. 
 
4. The electronic CAM, electronic gear be performed with virtual axis servo axis movement. Greatly improve the synchronization between the multiple servo axis. (applications: printer) 
 
(5), support the MODBUS (RTU) by 485 can be connected directly with man-machine 
 
Product advantage: 
 
1. Motor control firmware library mainly include 9 class main functions (including more than 40 kinds of function block), 6 back to zero point function, relative little exercise, absolute point movement, double closed-loop, speed type electronic gear, electronic CAM planning type, type a custom electronic CAM, velocity stack. 
 
2. The position closed-loop motion control related support trapezoidal curve, s-shaped (7 section 5 power, speed, cosine) the speed of the planning. 
 
3. All motion control function module interfaces comply with the regulations of international PLCopen organisation PART1 and PART2 part of the definition of interface, in order to achieve the upper application compatibility with other products. 
 
4. And this product to join the virtual spindle technology, to ensure that the real axis between the deceleration control position in the process of synchronization. 
 
5. Can also be implemented straight line interpolation, arc interpolation, helical interpolation, etc.
