FANUC A20B-3300-0121 is a two-axis high-speed axis control card for compatible FANUC CNC hardware. It processes servo-axis control commands within the CNC and is documented for two controlled axes, making it distinct from the four-axis A20B-3300-0120 card.

FANUC maintenance documentation lists A20B-3300-0121 in Series 15i/150i and Series 16i/18i/21i/20i-A hardware configurations. Compatibility depends on the CNC model, master PCB, card slot, servo software, system options and machine-tool builder configuration.

Two-Axis High-Speed Servo Control

The card supports CNC processing for two servo-controlled machine axes in an approved FANUC hardware configuration. Its function is different from a complete servo amplifier: the card belongs to the CNC control side, while the external servo amplifier supplies power to the motors.

A20B-3300-0121 vs. A20B-3300-0120

A20B-3300-0121 controls two axes, whereas A20B-3300-0120 controls four axes. FANUC also documents A20B-3300-0243 as a two-axis HRV3-related card, but this does not establish automatic plug-and-play interchangeability with A20B-3300-0121.

Replacement and Installation Checks

Match the complete A20B-3300-0121 number on the original card. Before replacement, confirm the CNC series, master PCB, installed axis-card position, servo software, controlled-axis count and system configuration. Back up parameters and machine data, isolate power and use anti-static handling procedures.
