The Bosch Rexroth 4WRPNH6C4B15P-2X/M/24FA6C (R901258582) is a state-of-the-art direct operated high-response valve, designed for precise control applications. This advanced component features an integrated digital axis controller that offers exceptional functionality for position control and DSC (Drive & Control Solutions) capabilities. It is equipped with both analog and digital sensor interfaces, providing versatility for various system requirements. The valve boasts a PROFIBUS interface with clock-synchronized command value presetting in accordance with the PROFIdrive profile V, ensuring high precision and responsiveness in dynamic applications. To cater to safety concerns, the 4WRPNH6C4B15P-2X/M/24FA6C valve has a separate supply voltage for the bus controller and power part of the output stage. Its sophisticated control electronics allow for comprehensive error detection, including cable break sensor technology, undervoltage, temperature monitoring of integrated electronics, communication errors, and watchdog synchronous monitoring. Additional functionalities of this Bosch Rexroth valve include error output capabilities at 24V or control of an isolator valve, actuating variable adaptation, dead band compensation, zero point correction, valve inflection compensation, friction compensation with direction-dependent amplification, as well as PIDT and state controller options. It also supports automatic or semi-automatic drive measurement for simplified controller optimization. For project planning and parameterization tasks associated with the IACR valves like this one, users can utilize the WinHPT commissioning software compatible with Windows 7 or Windows XP operating systems. This software greatly facilitates parameterization and diagnosis while offering convenient data management on a PC. The product is characterized by its size 6 design and belongs to component series X. It can handle a maximum operating pressure of up to 315 bar and allows a maximum flow rate of up to 40 liters per minute. With these specifications, Bosch Rexroth's 4WRPNH6C4B15P-2X/M/24FA6C valve stands out as an efficient solution for demanding hydraulic control tasks.

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.
