FANUC A02B-0166-B001 Servo Amplifier Drive Module

The FANUC A02B-0166-B001 Servo Amplifier Drive Module is a dedicated servo drive component identified by part number A02B-0166-B001, built for use in FANUC automation systems. As the amplification stage of a servo control loop, it receives control signals from the motion controller and delivers the amplified power required to drive a servo motor, enabling precise position, speed, and torque control within CNC machines and robotics applications. Designed to integrate with FANUC servo drive architectures, this module typically resides in a machine's control cabinet and works with the corresponding FANUC bus interfaces and power supplies that govern servo signaling and motor operation. The A02B-0166-B001 designation uniquely identifies this drive module for maintenance, replacement, or retrofit tasks, helping technicians match it to compatible FANUC equipment and firmware versions. When selecting a replacement, verify that the module's form factor, electrical interfaces, and control protocol align with your existing FANUC controller and servo motor to ensure compatibility for a proper retrofit.
