The Bosch Rexroth 4WRPNH6C4B40L-2X/M/24PF6G (0811403544) is a state-of-the-art high-response valve equipped with an integrated digital axis controller, designed for precise flow, position, and pressure control. This advanced component offers a range of functionalities including p/Q function and substitutional position/pressure or position/force control, along with NC functionality. The valve allows for command value presetting through an analog interface or a field bus interface, ensuring versatile connectivity options for different system requirements. The integrated axis controller based on high-response valves (IAC-R) boasts the capability to process command values either via the analog interface or through the field bus connection. Actual value signals are also provided through these interfaces, with additional readout available via the field bus. For enhanced safety and reliability, the valve features separate supply voltages for both the bus/controller and its power part. In terms of diagnostics and parameterization, Bosch's WinHPT commissioning software facilitates easy project planning tasks on PCs running Windows 2000 or Windows XP. This software allows for parameter setting, programming of NC functionality, error diagnosis, and efficient data management. The IAC-R valve's built-in control electronics are adept at detecting errors such as cable breaks, undervoltage conditions, overheating of electronics, communication errors, and watchdog timer lapses. Additional functions include ramp generation; internal command value profiling; enable function; error output; actuating variable adaptation; dead band compensation; zero point correction; valve inflection compensation; and friction compensation with direction-dependent amplification. This direct operated high-response valve is designed with robust control spool and sleeve in servo quality. It ensures a 4/4 fail-safe position when switched off. The unit supports various interfaces for command input and actual value feedback—ranging from four analog sensors to digital inputs such as length measurement systems—and offers configurable analog/digital I/Os along with fieldbus connectivity options like CANopen protocol DS408 and Profibus-DP Vo/V1. Quick start-up is facilitated by PC-based commissioning software that streamlines initial setup processes.
