The A06B-6127-H109 is a single-axis servo amplifier from FANUC’s Alpha i (A IS V) series, designed for industrial automation and CNC machine motion control. Classified as a high-voltage (HV) unit (V-360 class), it integrates core features like a brake (BRK), incremental encoder (INC), and keyed/tapered shaft compatibility to support precise, reliable motor operation. As a critical component of FANUC’s servo systems, it pairs with Alpha i series motors to deliver controlled, high-performance motion in manufacturing and machining applications.
