3. Advantages and Features

• Precision Hydraulic Control:
  The VT-HNC100-1-23/W-08-P-0 uses Rexroth’s Hydraulic Optimized Algorithm (HOA) to minimize hysteresis and achieve 98% repeatability in press applications. A case study in a plastics factory showed a 35% reduction in scrap rates after upgrading to this controller.
• Energy Savings:
  Its intelligent sleep mode and load-dependent power management cut energy costs by 22% in a 24/7 injection molding line, saving $9,000 annually.
• Rapid Commissioning:
  Pre-configured templates for presses, injection molding, and machine tools reduce setup time by 50% compared to manual tuning, ideal for OEMs scaling production.
• Reliability in Harsh Environments:
  IP65 protection and wide temperature range enable operation in high-dust steel plants or humid food processing facilities, with zero failures reported in 3+ years of field use.

4. Application Areas and Case Study

Application Areas:

• Machine Tools: CNC hydraulic presses and bending machines.
• Plastics Manufacturing: Injection molding machines with hydraulic clamping systems.
• Automotive: Hydraulic test benches for engine components.
• Aerospace: High-precision hydraulic actuators for wing flap testing.

Case Study:

5. Competitive Comparison

• Higher Integration: 8 valve outputs in a compact 150 mm width, 30% more channels than comparable units.
• Faster Response: 1 ms control cycle time (vs. 2–3 ms industry average), critical for high-speed presses.
• Built-in Safety: SIL 2 certification reduces external safety component costs by 20%.
• Wide Voltage Tolerance: Operates at 24 V DC ±15%, suitable for unstable power grids common in emerging markets.

6. Selection Recommendations

• Axis Requirements: Choose this model for 1–4 hydraulic axes; opt for the VT-HNC200 series for 5+ axes.
• Environment: Prioritize IP65-rated units for wet/dusty sites; use the IP20 variant (VT-HNC100-1-23) for clean control cabinets.
• Communication: Select CANopen for Rexroth-centric systems, PROFIBUS DP for legacy PLCs.
• Budget: Balance precision (±0.05 mm) with cost—this model offers 15% better accuracy than mid-range alternatives at a 10% premium.

7. Precautions

• Installation:
  • Mount horizontally with 20 mm clearance for heat dissipation; avoid direct sunlight or water spray.
  • Use shielded cables for valve connections to prevent EMI interference; torque terminals to 1.5 N·m.
• Configuration:
  • Commission via Rexroth’s VT-Software HNC to calibrate pressure/flow curves; validate safety functions (STO) quarterly.
  • Backup configurations to a secure drive—factory reset erases custom settings.
• Maintenance:
  • Inspect seals annually for IP65 integrity; replace if cracked.
  • Flush hydraulic oil every 2,000 hours to prevent valve blockages; monitor temperature sensors for early wear detection.
• Safety:
  • Disconnect power and 泄压 hydraulic lines before servicing—residual pressure can cause injury.
  • Never modify firmware without Rexroth approval, as it voids safety certifications.
