Abstract: This paper describes the design of intelligent industrial robots using servo control technology and multi-axis linkage CNC technology. This not only simplifies the system structure and shortens the development cycle but also reduces costs. The paper details the use of an axis control module (TAX CSY 84) and the SERCOS standard protocol to control the LEXIUM servo driver, achieving multi-axis linkage and ensuring motor operating accuracy, system response speed, and high reliability.

Currently, the effect of AC servo control is basically comparable to that of DC, while the cost is much lower and maintenance is more convenient. Replacing traditional DC servos with AC servos is an inevitable trend for future development. Multi-axis linkage CNC technology has developed rapidly in recent years and has been well applied in precision machine tools and industrial robots. Given the needs of product packaging, material handling, and highly repetitive operations, it is foreseeable that industrial robots will play an important role in some high-precision application areas. 1. System Introduction The device consists of three guide belts and a robotic arm. The robotic arm achieves three degrees of freedom of movement in space: the X and Y axes are parallel to the ground, and the Z axis is perpendicular to the ground. When an object appears on guide belt A, the robotic arm automatically adjusts, deciding whether to place the object on belt B or C based on its type. The robotic arm then returns to its standby point, awaiting the next cycle of operation. The X, Y, and Z axes are each driven by three servo motors, and the motor speed is controlled by the control system using a programmable interpolation algorithm. The following mainly introduces the control system of the industrial robot. 2. System Control Circuit Structure In the development of industrial robots, there are numerous speed and position control problems. These problems share the following characteristics: high precision in position and speed control, fast dynamic response, and large starting torque. Multi-axis linkage CNC technology can effectively solve these problems. Therefore, a multi-axis linkage CNC technology integrated scheme was selected in the design, as shown in Figure 1. It consists of a Premium master module, a motion control module (TSXCSY84), LEXIUM series servo drives, and SER servo motors. The motion control module and servo drives are connected via optical fiber and use the SERCOS protocol for high-speed data exchange, thus meeting the real-time requirements in industrial environments.
