FANUC A81L-0001-0165 Servo Motor Cable

The FANUC A81L-0001-0165 is a dedicated servo motor cable engineered for use in FANUC CNC systems. It serves as the critical link between the servo amplifier and the servo motor, carrying both power and encoder feedback signals in a single, shielded assembly. This cable ensures reliable power delivery to the motor while maintaining high-integrity transmission of position and speed data from the motor's built-in encoder. Designed to withstand the harsh conditions of industrial environments, including oil, coolant, and flexing, the A81L-0001-0165 provides long-lasting performance in machine tools, robots, and automation equipment.

Applications

The A81L-0001-0165 is used extensively in FANUC CNC machine tools such as machining centers, lathes, and grinders to connect servo motors on axes (X, Y, Z) and spindles. It is also employed in FANUC industrial robots for joint motors. Its robust construction ensures reliable operation in high-speed, high-precision applications where signal integrity is paramount.

Installation and Maintenance

The cable is supplied with connectors already attached, ready for direct connection to the servo amplifier and motor. During installation, care should be taken to avoid sharp bends and to secure the cable using appropriate clamps to prevent excessive movement. Periodic inspection for cuts, abrasion, or connector damage is recommended. In case of failure, replacement with an identical FANUC cable ensures proper fit and performance.
