Due to extremely high demand, please call 877-366-7226 for availability
The Bosch Rexroth 4WRPNH6C4B40L-2X/M/24PA6B (R901189134) is a state-of-the-art direct operated high-response valve equipped with an integrated digital axis controller (IACR). This advanced component combines the precision of flow, position, and pressure control with the versatility of pQ function, substitutional position-pressure, or position-force control, and NC functionality. It is designed for tasks requiring exacting hydraulic control with rapid response times. The valve is distinguished by its capability to accept command value presetting through either an analog interface or a field bus interface. Actual value signals can be provided via an analog interface and can also be read out through the field bus for real-time monitoring. The configuration and parameter setting are facilitated via the same field bus connection, ensuring ease of integration into existing systems. For diagnostics and parameterization, the WinHPT commissioning software is utilized. This software supports Windows 7 or Windows XP operating systems and offers features like programming of NC functionality, error diagnosis, and data management on a PC. The integrated control electronics within the valve enable detection of issues such as cable breaks, undervoltage conditions, temperature variations in electronics, communication errors, and watchdog timer lapses. Additional functions supported by this Bosch Rexroth valve include ramp generation, internal command value profiles, enable function toggle between analog/digital modes, error output signaling compatible with PLC logic systems up to 0.5 A output current capacity. It also provides actuating variable adaptation along with dead band compensation, zero point correction, valve inflection compensation as well as friction compensation which includes direction-dependent amplification. This high-response valve operates on one side with a failsafe position when switched off. Its interfaces support multiple sensor types including two analog sensors (0-10 V or 4...20 mA), one length measurement system (1 Vpp or SSI), plus additional analog sensors for comprehensive feedback options. Command values can be preset or responded to in analog current or voltage formats through a field bus connection that supports CAN bus with CANopen protocol DS-402 and Profibus-DP VoV protocols. The model has a size designation of 6X indicating its physical dimensions within Bosch Rexroth's product range. It can handle maximum operating pressures up to 315 bar and facilitate maximum flow rates up to 40 liters per minute. With these capabilities embedded in its design, this Bosch Rexroth valve stands as a versatile solution for sophisticated hydraulic control applications demanding high levels of accuracy and responsiveness.
Set-up:
The IAC-R valve basically consists of:
Direct operated high-response valve (1) with control spool and sleeve in servo quality Integrated digital axis controller (2) with analog and digital sensor interfaces and field bus connection (X3)High-response valve with integrated axis controller with analog interfaces (X1, X4, X7)
High-response valve with integrated axis controller with analog interfaces (X1, X4) and digital interface (X7)
Functional description
The IAC-R valve (Integrated Axis Controller based on high-response valves) is a digital high-response valve with integrated axis controller and the following functionalities:
Flow control Position control Pressure control p/Q function Substitutional position/pressure or position/force control NC functionalityThe command value presetting can alternatively be specified via an analog interface (X1) or via the field bus interface (X3) The actual value signals are provided via an analog interface (X1) and can additionally be read out via the field bus (X3). The controller parameters are set via the field bus. Separate supply voltage for bus/controller and power part (output stage) for safety reasons
WinHPT PC program
To implement the project planning task and to parameterize the IAC-R valves, the user may use the WinHPT commissioning software (see accessories):

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.Protective cap M12 with pin
