6. Selection Recommendations

• Load Requirements: Match the 40 A continuous current and 700 VDC bus voltage to your application’s mechanical demands.
• Environmental Conditions: Use optional cooling solutions for temperatures above 40°C or dust-resistant enclosures for harsh environments.
• Control System Compatibility: Verify analog/parallel interface or fieldbus module compatibility with your PLC or motion controller.
• Budget: Balance upfront costs with long-term savings from energy efficiency and reduced downtime.

7. Precautions

• Installation: Follow Rexroth’s guidelines for proper grounding and cable routing to prevent EMI. Use torque wrenches for secure mounting.
• Electrical Safety: Disconnect power before servicing. Use shielded cables for encoder and power connections to ensure signal integrity.
• Maintenance: Clean air vents quarterly to prevent dust accumulation. Check thermal grease and bearings every 20,000 hours.
• Firmware Updates: Regularly update firmware via Rexroth’s software to access new features and bug fixes.
