The Bosch Rexroth 4WRPNH6C4B15P-2X/M/24CA6A (R901131590) is a state-of-the-art direct operated high-response valve equipped with an integrated digital axis controller (IACR), offering advanced functionalities for hydraulic control systems. This sophisticated component is designed to provide precise flow, position, and pressure control, as well as pQ function and substitutional position-pressure or position-force control. Its NC functionality ensures that it can meet the rigorous demands of complex industrial applications. The valve's command value presetting can be input through an analog interface or via a field bus connection, while actual value signals are output through an analog interface with the option of field bus readout. The controller parameters are easily set using the field bus, enhancing user convenience and system integration. For safety purposes, the supply voltage for the bus/controller is separate from the power part output stage. Bosch Rexroth has also included several diagnostic and parameterization features in this valve model. The WinHPT PC program allows users to parameterize the IACR valves, program NC functionality, conduct diagnostics, and manage data comfortably on a PC running Windows 7 or Windows XP operating systems. The integrated control electronics of this valve are capable of detecting errors such as cable breaks, undervoltage conditions, overheating electronics, communication errors, and watchdog timer lapses. Additional functions include ramp generation, internal command value profiling, enable function customization (analog/digital), error signaling outputs compatible with PLC logic systems, actuating variable adaptation, dead band compensation, zero point correction, valve inflection compensation and friction compensation with direction-dependent amplification. This high-response valve features analog and digital interfaces for command and actual values input/output. It supports up to two analog sensors (0-10 V or 4-20 mA), one length measurement system (1 Vpp or SSI), plus two additional analog sensors. Command values can be set via analog current/voltage signals or through a field bus connection which includes CAN bus with CANopen protocol DS401 and Profibus-DP V0/V1. The Bosch Rexroth 4WRPNH6C4B15P-2X/M/24CA6A operates efficiently at a maximum pressure of 315 bar and can handle flow rates up to 15 liters per minute. It is recognized for its high precision in controlling hydraulic systems within a compact size 6 design from component series X.

Project planning and maintenance instructions

Connect the valve to the supply voltage only when this is required for the functional sequence of the machine. Do not use electrical signals provided via control electronics (e. g. "No error" signal) for switching safety-relevant machine functions (see also EN ISO 13849 "Safety of machinery – safety-related parts of control systems"). If electro-magnetic interference is to be expected, take appropriate measures ensuring the function (depending on the application, e. g. shielding, filtration). The devices have been tested in the plant and are supplied with default settings. Only complete devices can be repaired. Repaired devices are returned with default settings. User-specific settings will not be applied. The machine end-user will have to re-transfer the corresponding user parameters.
