Description
The Bosch Rexroth WE-2SPSU-M12X1 (R928028411) is a sophisticated electronic switching element designed to work seamlessly with mechanical/visual maintenance indicators in hydraulic filter systems. This component is engineered to enhance the functionality of the maintenance indicators by providing electronic monitoring capabilities. It attaches easily to the visual maintenance indicator using a locking ring, ensuring secure and reliable operation. The WE-2SPSU-M12X1 operates independently of the filter's nominal pressure. It uses a piston mechanism against a spring, which activates upon detecting an increase in back pressure or pressure differential. The attached solenoid moves with the piston, causing a visual pin to switch positions, indicating when maintenance is required. This system features a "cold start memory function," where the pin will remain in its extended position even after machine shutdown or pressure drop until it is manually reset. Incorporated within this device are reed contacts that respond to magnetic field changes, allowing for precise control with one or two switching points. The temperature for temperature suppression is effectively managed through the housing of the mechanical/visual indicator, maintaining optimal performance. It's important to note that while this model boasts modular construction and offers signal suppression during cold starts, it is not compatible with polyamide-made indicators (WOS.PA). The WE-2SPSU-M12X1 comes in different configurations: WESPMx includes a mating connector (not supplied), and WESPEN features a plug-in connection. With its robust design and advanced features, the Bosch Rexroth WE-2SPSU-M12X1 (R928028411) electronic switching element represents an essential accessory for hydraulic systems requiring reliable monitoring for efficient and timely maintenance interventions.
Features Maintenance indicators serve the monitoring of filters byindicating the exceedance of a pressure differential and/or abackpressure in the filter.They distinguish themselves by the following: – Modular structure – Mechanical-optical indicators WO with one switching pointand memory function – Electronic switching elements WE with one or two switching points – Possibility to suppress the signal during cold start
servo drives (servo drives), also known as "servo controller", "servo amplifier", is a controller used to control the servo motor, its role is similar to the frequency converter acting on the ordinary AC motor, is a part of the servo system, mainly used in high-precision positioning system. Generally, the servo motor is controlled through three ways of position, speed and torque to achieve high-precision transmission system positioning, and it is currently a high-end product of transmission technology. In the speed closed loop of servo drive, the real-time speed measurement accuracy of motor rotor is very important to improve the dynamic and static characteristics of speed control of speed ring. In order to find the balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used as the speed measurement sensor, and its corresponding common speed measurement method is M/T speed measurement. Although M/T velocity measurement method has a certain measurement accuracy and a wide measurement range, but this method has its inherent defects, including: 1) the speed measurement cycle must detect at least one complete code pulse, limiting the minimum measurable speed; 2) The timer switches of the two control systems used for speed measurement are difficult to maintain strict synchronization, and the accuracy of speed measurement cannot be guaranteed in the measurement occasions with large speed changes. Therefore, it is difficult to improve the performance of servo drive speed following and control by using the traditional speed loop design method. Servo driver principle: At present, the mainstream servo drivers all use digital signal processor (DSP) as the control core, which can realize more complex control algorithms, and realize digitalization, networking and intelligence. Power devices generally use intelligent power module (IPM) as the core design of the drive circuit, IPM internal integrated drive circuit, and has overvoltage, overcurrent, overheating, undervoltage and other fault detection protection circuit, in the main circuit also add a soft start circuit to reduce the impact of the start process on the driver.
