3. Advantages and Features

• Energy Efficiency Leadership:
  The HMV01.1R-W0018-A-07-FNN1 significantly reduces energy costs by regenerating up to 100% of braking energy, unlike traditional non-regenerative units that dissipate this energy as heat. In a automotive assembly line case study, this feature reduced annual energy consumption by 28%, translating to $15,000 in savings for a 20-axis system.
• Space-Saving and Scalable Design:
  Its compact form factor (263 mm width) and multi-axis support allow dense installation in control cabinets, ideal for space-constrained environments like semiconductor manufacturing. The module’s DC bus daisy-chaining capability enables seamless expansion of systems with minimal additional wiring, cutting installation time by 40% compared to non-integrated solutions.
• Robust Safety and Reliability:
  The SIL 3-certified safety features ensure compliance with the highest machinery safety standards, eliminating the need for external safety modules and reducing hardware complexity. The unit’s wide operating temperature range (-25°C to +55°C) and IP31 protection make it suitable for harsh environments, such as outdoor conveyors or high-dust manufacturing floors.
• Predictive Maintenance Support:
  Built-in voltage and temperature sensors monitor critical parameters in real time, enabling proactive maintenance via Rexroth’s IndraWorks software. This reduces unplanned downtime by 25% by detecting issues like capacitor degradation or cooling system blockages before they escalate.

4. Application Areas and Case Study

Application Areas:

• Industrial Machinery: Powers servo drives in CNC machines, robotic arms, and packaging equipment.
• Material Handling: Supports AGV fleets, conveyor systems, and automated warehouses.
• Energy Systems: Used in wind turbine pitch control and solar tracker systems for efficient energy management.
• Process Automation: Ideal for high-precision applications like 印刷 presses and medical device manufacturing.

Case Study:

5. Competitive Comparison

• Higher Power Density: Delivers 18 kW in a 263 mm width, 30% more power per unit volume than competing models.
• Full Regeneration Capability: Recovers 100% of braking energy, whereas many alternatives limit regeneration to 80% or less.
• Integrated Safety Compliance: Built-in SIL 3 features eliminate the need for external safety components, reducing system costs by 15%.
• Extended Temperature Range: Operates reliably in colder and hotter environments than most industry standards, making it suitable for global deployments.

6. Selection Recommendations

• Power Requirements: Choose the HMV01.1R-W0018-A-07-FNN1 for systems requiring 15–20 kW of continuous power. For higher or lower power needs, consider other HMV series models (e.g., HMV01.1R-W0045 for 45 kW).
• Environmental Fit: Ensure ambient temperature does not exceed +55°C and humidity remains below 95% (non-condensing). In dusty environments, use additional air filters to protect the internal blower.
• Safety Standards: Mandate this unit for machinery requiring risk category 4 or SIL 3 compliance, such as presses, shears, or systems with direct operator interaction.
• System Integration: Pair with Rexroth’s IndraDrive M servo drives for plug-and-play compatibility and advanced diagnostics. For non-Rexroth systems, verify DC bus voltage compatibility and communication protocol requirements.

7. Precautions

• Installation:
  • Mount the unit vertically in a well-ventilated cabinet, leaving at least 50 mm of clearance above and below for airflow.
  • Use shielded power cables and ensure proper grounding to minimize electromagnetic interference (EMI). Torque terminal screws to the manufacturer’s specified torque (8–10 N·m for power connections).
• Configuration:
  • Use Rexroth’s IndraWorks software to set DC bus parameters and enable regenerative braking. Validate safety functions (STO/SS1) during commissioning using TÜV-approved test tools.
  • Backup configuration data before firmware updates to prevent loss of custom settings.
• Maintenance:
  • Clean cooling vents monthly with compressed air to remove dust and debris, which can reduce airflow and cause overheating.
  • Inspect internal capacitors for swelling or leakage during annual maintenance; replace them every 7–10 years as part of preventive maintenance, even if no faults are detected.
• Safety Practices:
  • Disconnect AC power and wait at least 5 minutes for the DC bus capacitor to discharge before servicing.
  • Avoid modifying firmware or hardware without Rexroth’s approval, as this may void safety certifications and warranty coverage.
