Installation and Maintenance Practices

Proper installation and maintenance are essential for the optimal performance of Omron R7 series servo drives. Here’s a detailed guide based on the user manual to help you install and maintain your servo drives effectively:

• Impact and Load: The servo motors can resist impacts up to 98 m/s². Avoiding any heavy impacts or loads during transportation, installation, or removal is crucial. Always use a pulley remover to remove pulleys, couplings, or other objects from the shaft.
• Operating Environment: For ideal operation, the servo motor’s environment should maintain an ambient temperature of 0 to 40°C and a humidity level no greater than 85% RH without condensation. The area should be free from corrosive gases.
• Connecting to Mechanical Systems: Pay close attention to the axial loads for servomotors as specified in the manual. Exceeding these loads can reduce the service life of motor bearings and potentially cause damage to the motor shaft.
• Ambient Temperature Control for Servo Drives: Maintain the ambient temperature within the range that ensures the servo drive’s reliability. Use proper ventilation to prevent the drive’s temperature from exceeding 55°C, and be mindful of the drive surface temperature, which can be significantly higher than the ambient temperature.
• IP65 Water and Drip Resistance: The servo motors are rated IP65, offering protection against water jets and low-pressure water jets from any direction except through-shaft parts and cable outlets.
• Space Around Drives: Ensure at least 100 mm of space around the drives for adequate air circulation. This space is necessary to prevent uneven temperatures and to ensure proper heat dissipation.
• Mounting Direction: The drives should be mounted so that the model number can be seen properly, which typically means mounting them vertically.
• Keeping Foreign Objects Out of Units: Prevent contamination by covering the units during installation. Make sure to remove this cover after installation is complete. This will prevent metal particles, oil, dust, or water from entering the servo drives.

By following these specific installation and operational conditions from the Omron manual, you can ensure that your servo drives function correctly, maintain precision, and have a prolonged service life.
