Technical Architecture & Functional Positioning
The HNF01.1A-F240-E0051-A-480-NNNN serves as a high-power servo amplifier in electro-hydraulic control systems, providing fast and precise conversion of digital control commands into proportional hydraulic output. It operates at the control layer, interfacing directly with proportional servo valves and actuators.
The module integrates high-speed DACs, thermal monitoring circuits, and power stage protection, ensuring reliable operation under high-current, high-voltage industrial conditions. Its design includes fault detection, overcurrent protection, and isolation circuits to prevent failure propagation in critical systems.
Engineering value includes:
- High-Precision Motion Control: 16-bit DAC resolution enables micro-positioning of hydraulic actuators.
- Rapid Response: ≤1 ms step response ensures dynamic load compensation and accurate positioning.
- Operational Safety: Built-in protective features reduce risk of hydraulic overpressure or actuator damage.
Typical Application Scenarios
- High-speed CNC machining centers requiring servo-controlled hydraulic tool or workpiece positioning.
- Industrial presses and forming machines with precise hydraulic motion requirements.
- Mobile hydraulic applications in construction or mining machinery, controlling high-power actuators.
- OEM replacement for legacy Rexroth HNF servo amplifier modules.
- Retrofitting systems to increase motion accuracy, speed, and reliability in hydraulic automation.
