Bosch Rexroth VT-HNC100-1-14/134 – High-Performance Digital Axis Controller | HNC100 Series
Engineering Background
The VT-HNC100-1-14/134 is a dedicated digital axis controller developed by Bosch Rexroth for closed-loop electrohydraulic positioning and velocity control. Engineered within the HNC100 platform, it integrates seamlessly with Rexroth proportional and servo valves, delivering deterministic real-time control for demanding industrial motion applications.
Product Positioning
Designed for procurement engineers and OEM system integrators who require a proven, drop-in replacement or new-build axis controller with full Rexroth ecosystem compatibility. The VT-HNC100-1-14/134 eliminates the need for external PID tuning hardware by embedding all control logic, diagnostics, and parameterization within a single compact module.

System Architecture & Signal Flow
The VT-HNC100-1-14/134 operates as the intelligence layer between the machine PLC and the hydraulic valve. The PLC issues a ±10 V position or velocity setpoint to the controller’s command input. The module compares this against the actual-value feedback (linear transducer, encoder, or pressure sensor) and computes a corrected ±10 V output to the proportional or servo valve amplifier. Internal ramp generators, limit monitors, and enable logic ensure safe, smooth axis motion without additional external circuitry.

Technical FAQ
Q: Is VT-HNC100-1-14/134 a direct replacement for older HNC100 variants?
A: Yes, the HNC100 series maintains backward hardware compatibility across most sub-variants. Verify the firmware version and parameter set with your Rexroth documentation before commissioning.
Q: What software is required for parameterization?
A: Bosch Rexroth WinHNC or BODAC software (Windows-based). A standard RS-232 serial cable connects to the module’s parameterization port.
Q: Can this controller work with non-Rexroth valves?
A: The ±10 V analog output is industry-standard and can drive any proportional valve amplifier accepting this signal. Verify amplifier input impedance and scaling.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Contact us for current availability.
Q: Do you provide a test report or functional verification?
A: Yes, functional test reports are available upon request for critical applications.
