Bosch Rexroth SYHNC100-NIB-22aW-24-P-D-E24-A012 – Electro‑Hydraulic Axis Controller for Precision Motion

The model SYHNC100-NIB-22aW-24-P-D-E24-A012 appears to be part of the Rexroth HNC100 family—digital single‑axis controllers designed for proportional and servo‑hydraulic applications. From my experience, this series is chosen for presses, test benches, metal forming, and mold/tools where closed-loop position/pressure control is essential. You might notice the “E24” suffix, which typically indicates a 24 V DC supply variant, commonly used in cabinet installations.

Key Features

• Closed-loop control for hydraulic axes – Typically supports position, pressure/force, and velocity loops with fast response for servo and proportional valves.
• Flexible feedback inputs – Commonly accommodates LVDT/inductive position transducers, SSI encoders, and analog pressure sensors for reliable measurement.
• Analog command and valve drive – ±10 V setpoint I/O and valve outputs (±10 V or PWM) allow straightforward integration with existing power stages and Rexroth valves.
• 24 V DC cabinet operation – The E24 designation usually points to a 24 V DC supply, simplifying control panel wiring and safety design.
• Fieldbus connectivity – In many cases, HNC100 units provide RS-232 for commissioning and CANopen; some subvariants support PROFIBUS DP.
• Commissioning tools – Parameter sets, diagnostics, and autotuning aids help shorten startup; technicians often note faster recovery after maintenance.
• Robust industrial build – Designed for long service life in vibration and temperature‑variable environments typical of hydraulic machinery.

Technical Specifications

Application Fields

Commonly used in hydraulic presses, metal forming lines, plastic injection and blow molding, die‑casting machines, heavy test systems, servo‑hydraulic actuators on R&D rigs, and cylinder positioning for machining/handling equipment. One thing I appreciate is how the HNC100 family handles mixed control modes—switching between position and pressure control is straightforward in many setups.

Advantages & Value

• Reliable closed-loop hydraulics – Proven control behavior reduces scrap and improves repeatability, especially on long‑stroke cylinders.
• Compatibility with Rexroth hydraulics – Works well with Rexroth proportional/servo valves and common transducers, limiting integration risks.
• Lifecycle cost savings – Parameter‑based commissioning saves service hours; spare availability for HNC series is typically strong.
• Supportable architecture – Clear diagnostics and serial access allow maintenance teams to troubleshoot quickly; in many cases remote guidance is enough.

Installation & Maintenance

• Control cabinet – Install in an enclosed panel (IP54 or above suggested on shop floors), with adequate ventilation and 24 V DC power conditioning.
• Grounding and wiring – Use shielded cables for LVDT/SSI and analog lines; route power separately from signal to reduce noise.
• Hydraulic valve drive – Match output type (±10 V or PWM) to the valve amplifier specification; verify null adjustment and dither settings during tuning.
• Commissioning – Back up parameters, run basic axis identification, and fine‑tune PID/feed‑forward under load. Many teams report a noticeable improvement after optimizing pressure ramps.
• Routine care – Keep the cabinet dust‑free, check connectors annually, review calibration of pressure sensors, and update firmware when recommended by Rexroth.
• Safety – Integrate with external safety relays/PLCs; ensure safe valve de‑energization and cylinder support during maintenance.

Quality & Certifications

• Typically CE-marked; UL/CSA recognition available on many Rexroth control modules
• Manufactured under ISO 9001 quality systems
• RoHS compliance in most configurations
• 365‑day warranty support

Related Components (for a complete setup)

• Rexroth proportional/servo valves with ±10 V or PWM interface
• LVDT or SSI linear transducers for cylinder position
• Pressure transducers (4–20 mA) for pressure/force control modes
• 24 V DC industrial power supply with sufficient reserve and buffering
• Fieldbus gateways (if upgrading to PROFIBUS/CANopen in mixed networks)

Note: The HNC100 family includes several subvariants. The SYHNC100‑NIB‑22aW‑24‑P‑D‑E24‑A012 designation seems to indicate a 24 V DC, pressure/position-capable unit; specific I/O and bus options can vary. If you share your target valve type and feedback sensors, we can verify exact compatibility and pinout before shipment.
