Installation Guidelines

To ensure optimal thermal dissipation and mechanical life, mount the HC-KFS73B servo motor on a metallic surface acting as a heat sink. Ensure the shaft alignment matches the load coupler with a tolerance of less than 0.03 mm to prevent premature bearing wear. Secure all power and encoder cables using strain relief fittings, keeping high-voltage motor lines separated from low-voltage signal cables to mitigate electrical noise. During commissioning, verify that the electromagnetic brake is fully released electrically before initiating motor rotation.
