Description
In terms of power supply: It is powered through a 50mA fuse, which can effectively limit the on-site circulating current and improve safety. It adopts dual 24Vdc power feeding and is equipped with a green LED power indicator light, which is convenient for users to intuitively understand the power supply status. In terms of control functions: It has programmable numerical control operations, supports the pressure contention of the position controller and NC language, and is capable of achieving complex control tasks. The controller variants can be freely configured, and it supports subroutine technology and conditional alternate closed-loop control (position/pressure), making it suitable for various complex industrial control scenarios. In terms of communication interfaces: It complies with -8, 16, or 24 digital inputs and outputs, supports PROFIBUS DP, has EC directives (CE marking), and can communicate with the PLC through CANopen or InterBus-S. This makes it convenient for integration with other devices and enables it to be well integrated into the industrial automation system. In terms of environmental adaptability: It is suitable for harsh industrial environments, can withstand the impacts of vibration and dry climate, and can operate stably in a variety of complex industrial environments. In terms of application fields: It is widely applied in industrial fields such as machine tools, plastic processing machinery, special measurement systems, and transmission lines. It can also be used in railway vehicles and situations with a large amount of liquid. It includes control scenarios such as incremental or absolute (SSI), analog 0 to ±10V and 4 - 20mA, and a reference voltage of 10V for presses, and can achieve precise control of related equipment.
Practical Application Cases:
Semiconductor Lithography Machine: In semiconductor lithography machines, the VT-HNC series controllers (belonging to the same Rexroth digital axis controller series as R900978416) drive linear motors. By utilizing the feedback from high-resolution encoders (23-bit resolution) and adaptive compensation algorithms, nanometer-level stepping of the wafer stage can be achieved, facilitating the mass production of the 7nm process. Its multi-axis synchronization technology can make the phase error of multiple servo motors less than 0.01°, meeting the extremely high precision requirements of semiconductor manufacturing.
New Energy Battery Assembly Line: On the new energy battery assembly line, Rexroth digital axis controllers are used for 32-axis synchronous control. Through precise position and speed control, the production capacity of a single line can exceed 200,000 sets per month, and the defect rate is lower than 50ppm, improving production efficiency and product quality.
Satellite Antenna Calibration: In satellite antenna calibration, the Rexroth controller can complete angle correction at the level of 0.001° in a vacuum and low-temperature environment. This benefits from its high-precision control algorithm and stable performance, ensuring zero interruption of space communication.
Corrugated Paper Printing Machine: Rexroth's IndraMotion for Printing solution is applied to corrugated paper printing machines. Adopting shaftless drive technology, digital axis controllers ensure real-time and precise synchronization of the single drive shafts in all equipment modules. Advanced corrugated paper printing machines can reach a maximum working speed of 300m/min, and can complete the printing, folding, slotting, and punching processes of 400 corrugated papers per minute. Equipment configured with 10 printing, coating, and drying stations can fully produce high-quality products continuously at the maximum operating speed.
Machine Tool Machining: In machine tool machining, Rexroth digital axis controllers are used to control the various motion axes of the machine tool, such as the X, Y, and Z axes. Through precise position control and speed control, accurate positioning of the tool can be achieved, and various complex part contours can be machined, ensuring machining accuracy and surface quality. For example, when machining aircraft engine blades, micron-level machining accuracy can be achieved, meeting the strict requirements of the aerospace field for part machining.
