Simply put, motion control card and PLC are controllers, mainly responsible for the motion axis control, input and output signal control in industrial automation systems. So, what is the difference between motion control card and PLC?
PLC: The main function is to control the switch quantity logically, and has simple motion control (linear trajectory control), calculation, data processing and other functions, usually using touch screen for man-machine interface. It has the advantages of reliable work and simple programming, but its motion control function is relatively simple, and can not meet the complex and precise occasions. PLC application process is mainly through PLC+HMI, which leads to the visual interface is greatly limited, the biggest problem in the practical application process is not to achieve the mapping function; Now due to the development and application of machine vision, the combination of PLC and machine vision is very difficult. Motion control card: It is a pulse motion control card with high integration and reliability based on PCI bus, which can control multiple stepper motors or servo motors. Motion control card is based on PC bus, using high performance microprocessor (such as DSP) and large scale programmable devices to achieve multi-axis coordination control of multiple servo motors, a high performance stepper/servo motor motion control card, powerful.

The main advantage of motion control card is to use the powerful functions of PC, such as CAD function, machine vision function, software advanced programming, etc. The function of FPGA+DSP/ARM +DSP chip is used to realize high-precision motion control (multi-axis linear and circular interpolation, motion following, PWM control, etc.). The advanced programming language C++, C#, VB, VB. Net, labview and other programming languages are used for development. The API interface functions provided by motion control card manufacturers are used in programming to realize the use of control card resources. The motion control card controls the servo motor or stepper motor by sending pulses to control the servo or stepper drive, and realizes the IO control of relays, sensors, cylinders and so on by reading input signals and controlling output signals. Motion control card can be said to be specially designed to solve the motor movement, it puts a lot of the details of the implementation of the movement wrapped up, leaving the user more simple interface and command, use will feel more convenient.
Zhongweixing is one of the earliest enterprises engaged in independent research and development of motion control in China. From basic point motion to multi-axis interpolation, from simple circular motion to complex spatial trajectory, Zhongweixing always adheres to independent research and development. Zhongweixing has mastered multi-axis interpolation technology, multi-axis synchronization technology, high-speed fieldbus, tension control technology, industrial robot control technology and many other core technologies. The motion control card and servo drive developed by the company are widely used in textile furniture, electronic assembly, metal processing and other industries, which are highly praised by the industry. It has gradually become a leading supplier of operation control solutions in China.
