REXROTH VT-HNC100-1-22/W-08-C-0 – Electrohydraulic Axis Controller for Precise Position, Velocity, and Pressure Control

The REXROTH VT-HNC100-1-22/W-08-C-0 is a compact electrohydraulic motion controller designed to close position, speed, and pressure/force loops on hydraulic axes. From my experience, this HNC100 family is often chosen when a PLC alone can’t deliver the deterministic, high-resolution control needed for presses, molding machines, test benches, or heavy industrial actuators. You might notice that the “W-08-C” option set is typically associated with expanded I/O and a CAN-based fieldbus, making it practical to retrofit into existing cabinets alongside standard 24 VDC control gear.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week for in-stock; no more than one month at the latest
• Payment terms: 50% advance payment; full payment before delivery
• Express delivery: FedEx, UPS, DHL
• Every unit is visually inspected and function-checked before dispatch; traceable packing slip and test notes included.

Key Features

• Closed-loop hydraulic control – Position, velocity, and pressure/force loops for single-axis or coordinated hydraulic actuation.
• Integrated analog and digital I/O – Typically supports 0–10 V / 4–20 mA command and feedback channels plus discrete I/O for limits, interlocks, and valve enable.
• CAN-based fieldbus (C option) – The “C” option commonly indicates CAN/CANopen connectivity for setpoint, diagnostics, and PLC integration.
• Service/commissioning port – A serial service interface (RS‑232 in many cases) for setup, tuning, and firmware service.
• Deterministic control response – Purpose-built for electrohydraulics where valve dynamics and sensor filtering matter.
• Cabinet-friendly form factor – Designed for control cabinets with standard 24 VDC infrastructure and DIN-rail mounting.
• Rexroth ecosystem compatibility – Works well with Rexroth proportional valves, pressure transducers, and SSI/incremental feedback in typical machine builds.

Note: Exact I/O count and bus options vary by variant; the “W-08-C-0” configuration is commonly associated with extended analog channels and CAN. We’ll verify your nameplate and option code before shipping.

Application Fields

• Hydraulic presses and metal forming – precise stroke control, pressure holding, and force limiting
• Injection molding and die casting – repeatable injection profiles and clamping force regulation
• Test stands and materials testing – position/force loops with fine tuning and fast response
• Sawmill and cutting machines – synchronized feed axis control under varying loads
• Mobile/industrial hydraulics retrofits – bridging analog valves and modern PLCs via CAN

Advantages & Value for Procurement

• Reliability – Proven Rexroth control platform; in many cases these run for years with minimal service.
• Compatibility – Pairs well with proportional valves, pressure sensors, and encoders already on your line.
• Cost containment – Extends existing hydraulic assets rather than replacing full machine controls.
• Supportability – Clear commissioning workflow via service port; we can provide parameter backups and quick-swap setup files.

Installation & Maintenance

• Cabinet environment – Mount on 35 mm DIN rail inside a ventilated cabinet; keep ambient 0…50 °C and allow airflow around heat sources.
• Power & grounding – Use a regulated 24 VDC supply with proper PE grounding; separate power for inductive loads when possible; add surge suppression at valve coils.
• Wiring practices – Use shielded cables for analog and encoder lines; route signal and power separately; tie shields at the controller end to avoid ground loops.
• Commissioning – Connect via the service interface for parameter setup and loop tuning; save a parameter set after acceptance tests.
• Routine maintenance – Periodically check terminal torque, connector tightness, and filter logs/diagnostics; schedule firmware updates during planned downtime.
• Safety – Implement hardwired E‑stop and valve de‑energize circuits; verify motion interlocks before enabling hydraulics.

Quality & Certifications

• CE compliant design for industrial environments
• UL/cUL recognition for control equipment (typical for Rexroth control electronics)
• RoHS-conforming materials
• Manufactured under ISO 9001 quality systems
• Warranty: 365 days standard

Recommended Supporting Components

To speed up integration and keep spares consistent, these components are commonly paired with HNC100 controllers in the field:

• 24 VDC Power Supply – Industrial PSU, 5–10 A with DC‑OK relay, to isolate logic from inductive loads.
• Proportional Valves (REXROTH) – Compatible servo/proportional valves with coil drivers sized to the application.
• Pressure and Position Sensors – 4–20 mA pressure transducers and SSI/incremental encoders or LVDTs for closed-loop feedback.
• CAN/CANopen Accessories – CAN cabling, terminators, and (if required) gateway to your PLC fieldbus.
• Shielded Signal Cabling – Low-noise cable sets for analog/encoder runs to preserve measurement fidelity.

Customer feedback: “We swapped an aging analog card for the VT‑HNC100 and immediately saw tighter pressure control on a 250‑ton press. Tuning took under an afternoon and we retained our existing PLC.”

One thing I appreciate is how forgiving the HNC100 is during retrofits—its I/O and bus options tend to map cleanly to real machines. If you share your exact valve and sensor list, we’ll confirm the “W‑08‑C‑0” option set matches and pre‑load a configuration so commissioning goes faster.
