REXROTH servo controller

The REXROTH solenoid valve is used in the fluid system to achieve the on/off of the fluid circuit or change the direction of fluid flow. It generally has a spool that can slide under the electromagnetic force of the coil. When the spool is in different positions, the passage of the solenoid valve is also different. There are several working positions of the valve core, and this solenoid valve is called a multi position solenoid valve: the interface on the valve body, which is the number of passages of the solenoid valve, has several passages, and this solenoid valve is called a multi way solenoid valve.
Bosch Rexroth servo controller: integration of precision and intelligence
As a core technology carrier in the field of industrial automation, Bosch Rexroth servo controllers have become the "core brain" of precision scenarios such as manufacturing, robotics, and semiconductors with millimeter level accuracy, microsecond level response, and deep intelligence. Taking the classic VT-HNC100 series (such as R901134614) as an example, its performance advantages can be summarized into the following five dimensions:
1、 REXROTH servo controller accuracy: redefining manufacturing boundaries
μ - level positioning: using high-resolution encoder feedback (23 bit resolution) and adaptive compensation algorithm, the repeated positioning accuracy can reach ± 0.001mm, meeting high-precision requirements such as precision machine tool tool trajectory control and optical component polishing.
Nanoscale motion control: through multi axis synchronization technology (such as SYNC HRO-SPHERE?)? ）When multiple servo motors with a phase less than 0.01 ° are applied to LCD panel handling robots, the yield rate is increased to 99.99%.
Anti interference design: The entire series comes standard with EMC electromagnetic compatibility enhancement technology, which can maintain signal stability even in strong interference environments such as electric arc furnaces and welding workshops.
2、 REXROTH High Frequency Dynamic Performance: The Art of Balancing Speed and Stability
Microsecond level response: The current loop refresh cycle is as low as 62.5 μ s, and the speed loop response frequency reaches 3kHz, which can instantly capture load changes. In the five axis linkage machining center test, the contour was reduced by 50%.
Adaptive filtering: Built in vibration suppression algorithm, automatically identifies mechanical resonance points and dynamically adjusts filter parameters. In a certain automotive welding line application, the end shaking of the robotic arm is reduced by 80%, and the welding speed is increased by 35%.
Overload capacity: The instantaneous overload torque reaches 300% of the rated value, supporting short-term impact loads (such as emergency stop rebound control of the press machine), protecting the equipment from damage.
3、 REXROTH Intelligent Core: Carrier of Industry 4.0
Open protocol compatibility: Supports mainstream industrial protocols such as EtherCAT, PROFINET, OPC UA, and seamlessly integrates with MES/ERP systems. A certain smart factory directly issues production parameters through a controller, reducing the changeover time by 70%.
Predictive maintenance: Integrating multi-dimensional sensors such as temperature, vibration, and current to analyze equipment health status in real-time. The case shows that the accuracy of fault warning for a certain photovoltaic panel production line reaches 92%, and maintenance costs are reduced by 40%.
Digital Twin Support: Provides PC simulation software IndraWorks, which can complete parameter tuning, logic verification, and debugging in a virtual environment
