FANUC A06B-6044 - A06B-6044-H112 control unit (retrofit)

The Fanuc AC Spindle Servo Unit A06B-6044-H112 is an analog spindle drive from the Fanuc 6044 series. The unit handles the regulation and control of the spindle motor in CNC machines, providing precise speed and power control of the connected AC spindle motor. It is designed for use with a Fanuc Model 12 AC spindle motor and belongs to the medium-power class of spindle drives with an output of 12 kW. The unit is used in CNC-controlled machining centers and machine tools operating with analog Fanuc spindle systems. It is compatible with Fanuc Model 12 as well as Model 18P spindle motors and communicates with the higher-level CNC control via the integrated control card. The software ROM version is J03. The next unit in the series is the A06B-6044-H130. The housing of the A06B-6044-H112 consists of a robust anodized metal enclosure. The spindle control card (Spindle Card PCB) is permanently mounted on the top of the drive. The unit features internal ventilation. The drive type is controlled by a specific ROM chip. The standard control PCB installed is the A20B-1000-0690, which forms the interface between the NC/CNC control and the spindle unit. Alternatively, the control PCB A20B-1000-0693 can be used.
