Description
Bosch Rexroth SYHNC100-NIB-23/W-24-P-D-E23-A012 Heavy‑Duty Digital Axis Controller for Hydraulic Motion
The SYHNC100-NIB-23/W-24-P-D-E23-A012 is built on Bosch Rexroth’s proven HNC100 platform for closed-loop hydraulic axis control. From my experience, this series is a go-to when you need precise position, pressure, or force control on cylinders and servo-hydraulic axes—especially in presses, injection molding machines, test rigs, and retrofit modernization projects. It seems to be designed for tough environments, with deterministic control cycles, robust 24 V DC power, and encoder/sensor interfaces that make commissioning straightforward.

Key Features
- Closed-loop hydraulic axis control: Position, pressure, and force control with stable loop behavior for heavy-duty applications.
- 24 V DC industrial power: Standard cabinet supply simplifies integration with existing control panels.
- Flexible feedback interfaces: Typically supports incremental/SSI encoders and analog transducers for cylinders and valves.
- Fieldbus connectivity: Options on this family often include CANopen or PROFIBUS DP; a service port simplifies commissioning.
- Deterministic cycle times: Consistent control loop timing helps achieve repeatable part quality on presses and molding machines.
- Robust I/O set: 24 V digital I/O and ±10 V analog signals for valve command, sensor inputs, and interlocks.
- Commissioning tools: Parameter-based setup reduces startup time and keeps maintenance predictable.
Technical Specifications
| Brand / Model | Bosch Rexroth / SYHNC100-NIB-23/W-24-P-D-E23-A012 (HNC100 series variant) |
| HS Code | 8537.10 (Programmable controllers; control panels for ≤1000 V) |
| Power Requirements | 24 V DC nominal (typical industrial supply); consumption is low compared to a servo drive and usually under 20 W |
| Operating Temperature | 0…+50 °C in a ventilated control cabinet (non‑condensing) |
| Signal Input/Output Types | 24 V digital I/O; ±10 V analog outputs for valve command; analog inputs for pressure/position transducers; incremental/SSI encoder feedback (E23 option typically indicates encoder capability) |
| Communication Interfaces | Service port (commonly RS‑232/USB adaptor); fieldbus on this family often CANopen or PROFIBUS DP |
| Installation Method | Control cabinet mounting; follow standard EMC wiring and grounding; pair with Rexroth proportional/servo valves |
Note: Exact I/O population and bus options depend on the specific option string; the above reflects common capabilities of SYHNC/HNC100 variants.
Application Fields
- Metal forming and hydraulic presses needing fast switchover between position and pressure control.
- Injection molding and die casting machines where repeatability and mold protection typically matter.
- Servo-hydraulic test rigs and fatigue testers with high-resolution feedback.
- Timber and paper machinery (log handling, press sections) and retrofits of legacy electro-hydraulic systems.
- General industrial machinery requiring closed-loop axis control without a full-blown motion PLC.
Advantages & Value
- Reliability: HNC100 lineage is known for long service life and stable loop control in harsh environments.
- Compatibility: Works well with Rexroth proportional valves, standard SSI/incremental encoders, and common pressure transducers.
- Lower integration effort: Parameter-based commissioning and familiar 24 V I/O save build time and panel space.
- Lifecycle support: In many cases, firmware tools and spare parts are still available across the HNC100 family.
- Total cost: Compared with replacing a full PLC platform, a dedicated axis controller usually cuts downtime and retrofit cost.
One thing I appreciate is how maintenance teams can replace a unit, reload the parameter set, and be back in production quickly. A maintenance supervisor from a press line told us the “swap‑and‑run” approach reduced unplanned downtime by more than half compared to their old card rack.
Installation & Maintenance
- Cabinet & environment: Mount in a clean, ventilated control cabinet (IP54 or better). Maintain 24 V DC within tolerance; avoid condensation.
- Wiring & EMC: Use shielded cables for encoder and analog signals; ground shields at the cabinet side; segregate power and signal wiring.
- Hydraulic integration: Pair with properly sized Rexroth proportional valves and calibrate deadband/zero to match your hydraulics.
- Safety: Implement external E‑stop circuits and valve de‑energization; the controller should not be the sole safety device.
- Routine maintenance: Back up parameter sets; inspect connectors quarterly; keep vents free of dust; check encoder cables and transducer health.
- Firmware & tools: Keep service software and firmware at supported revisions; update during planned shutdowns after backing up configs.
Quality & Certifications
- CE compliant for industrial control equipment (typical for this series)
- RoHS-compliant manufacturing practices
- Produced under ISO 9001 quality management by the manufacturer
- 1-year warranty (365 days) as stated above
Helpful Accessories
- SSI/incremental encoder cables and adapters
- Pressure/force transducers (4–20 mA or ±10 V) matched to your cylinder ranges
- Rexroth proportional/servo valves with ±10 V command inputs
- Fieldbus interface cabling (CANopen or PROFIBUS DP where applicable)
