Product Overview

The SYHNC100‑NIB‑23/W‑08‑P‑D‑E23‑A012 belongs to Rexroth HNC100 series digital hydraulic axis controller. It is a dedicated closed‑loop controller for electro‑hydraulic servo axes, controlling proportional/servo valves for position, speed and pressure‑force modulation. It acquires feedback signals from linear displacement transducers, pressure sensors and incremental encoders, executes real‑time hydraulic control algorithms, and outputs analog command signals to drive hydraulic servo‑valves.

This controller addresses hydraulic‑motion‑control challenges: high‑dynamic closed‑loop modulating control for hydraulic axes, on‑board I/O integration for sensor‑termination, and drop‑in spare‑part compatibility for legacy HNC100 retrofit projects. Built‑in diagnostics detect loop faults and report fault status over CAN bus. Automation and hydraulic‑system engineers, plant‑maintenance technicians and retrofit integrators benefit most. It applies for steel‑mill hydraulic actuators, test‑bench hydraulic positioning, press‑machine closed‑loop control and heavy‑duty industrial‑automation hydraulic‑loop applications.

Key Application Notes

• Specialized hydraulic axis controller; requires external servo‑valve, position‑feedback sensor and 24 VDC power supply; cannot operate standalone
• Full‑order code defines hardware configuration: I/O quantity, encoder type, connector style and conformal‑coated option
• Not hot‑swap capable: unit power must be removed before replacement
• CANopen bus used for host‑PLC communication; local parameter configuration via Rexroth service‑tool software
• Supports configurable fail‑safe behaviour upon hardware or bus fault for safety‑critical hydraulic‑modulating loops
• Conformal‑coated PCB variant available for high‑humidity, high‑contaminant cabinet environments
• Original OEM production is obsolete; widely‑used aftermarket spare for existing hydraulic‑system maintenance‑retrofit projects
• Commissioning must follow Rexroth HNC100 hydraulic‑controller manual for valve‑loop tuning and sensor‑calibration
