Genuine FANUC A06B-6111-H030 Alpha i (αi) servo amplifier module (SVM). This unit drives FANUC Alpha i and Beta i servo motors for CNC axis and robot motion control. It connects to the FANUC CNC or robot controller through the FSSB (FANUC Serial Servo Bus) and is used across FANUC 0i / 30i / 31i / 32i series controls and FANUC robot controllers such as the R-30iB series. It is a core drive module inside FANUC robot control cabinets and CNC servo systems. Every unit is inspected and tested before shipment. We supply new original or tested-used original (Grade A) and confirm the exact fitment — including the hardware/firmware suffix (#Hxxx) — against your drive configuration or unit nameplate before you order. |

The A06B-6111-H030 is a servo amplifier (SVM) in the FANUC Alpha i drive family. It takes the DC bus supplied by the drive power module and converts it into the regulated 3-phase output that drives a servo motor, while closing the current and position loop through FSSB communication with the CNC or robot controller. Because each amplifier drives one axis or robot joint, a failed module stops that axis from moving — making it a critical spare for minimizing downtime.
Specific alarm codes vary by control model and are not officially documented here. Send your unit nameplate or control model and we help identify the fault.
