Working Principle

Material & Structural Characteristics

• Housing: Black aluminum alloy extruded shell, surface oxidation anti-corrosion, excellent heat dissipation performance
• Internal PCB: Multi-layer industrial control circuit board with conformal coating anti-oil mist and moisture in hydraulic workshop
• Terminal Connectors: Screw locking industrial terminal blocks, high vibration resistance for machine tool operation shock
• Heat Dissipation: Full aluminum passive heat sink integrated on housing side wall, no fan design to avoid oil dust clogging failure
• Modular split structure: Separate communication interface sub-board and main control motherboard for maintenance replacement

Installation Requirements

1. DIN rail mount inside electrical control cabinet, reserve ≥10mm clearance top and bottom for heat convection
2. Isolate hydraulic valve drive wiring and fieldbus communication wiring into separate cable ducts to reduce cross-interference
3. 24VDC power input must add EMC filter module to suppress hydraulic pump frequency converter power grid noise
4. Displacement transducer shield cable single-point grounding at controller terminal to eliminate analog signal drift
5. Do not install controller within 1m distance of large hydraulic power units to avoid vibration damage to internal circuit solder joints
6. Cabinet must install oil mist filter ventilation fan to prevent hydraulic oil vapor corrosion of PCB terminals

Typical Application Scenarios

• Metal forming hydraulic press, deep drawing press force & position closed-loop control
• CNC hydraulic grinding machine, precision hydraulic machining tool axis positioning
• Plastic injection molding machine clamping & injection hydraulic axis motion control
• Metallurgical rolling mill hydraulic cylinder synchronized positioning control
• Wind turbine hydraulic pitch adjustment cylinder precision control
• Construction machinery hydraulic test bench multi-axis motion simulation

Operation & Maintenance Precautions

1. Motion program download and parameter modification only allowed via official Rexroth WinHNC engineering software
2. Before axis automatic operation, execute manual jog test to calibrate transducer zero offset and valve gain parameters
3. Quarterly inspection of terminal screw tightness to prevent vibration-induced loose wiring signal loss
4. If proportional valve output drive circuit fault occurs, cut hydraulic pump power before replacing internal drive sub-board
5. Avoid controller cabinet door long-term open; oil mist ingress will cause PCB circuit short-circuit failure
6. Firmware upgrade requires stable uninterrupted 24VDC power supply to prevent program brick damage
7. Store backup of all motion recipes on external PC storage before factory reset or firmware update
