GE Fanuc A20B-1003-0090/05A Servo Drive Board | CNC Servo Control Module | Series 0 / 15 / 16 Platform
Engineering Background
The A20B-1003-0090/05A is a servo drive control board manufactured under the GE Fanuc joint venture, designed for integration into FANUC CNC systems operating on the Series 0, Series 15, and Series 16 platforms. This board governs closed-loop servo axis control, interfacing directly with the servo amplifier and feedback encoder to deliver precise motion commands in demanding industrial environments.
Product Positioning
Targeted at procurement engineers and MRO specialists managing CNC machine tool fleets, this board serves as a direct OEM-equivalent replacement for failed or degraded servo control circuits. Konmask.com supplies this unit from verified industrial surplus and refurbished channels, with full functional testing prior to dispatch.

System Architecture & Signal Flow
The A20B-1003-0090/05A resides within the CNC control cabinet, receiving axis motion commands from the CNC CPU board via the backplane bus. It translates these commands into analog or digital velocity/torque references for the servo amplifier (e.g., FANUC α-series or β-series amplifiers). Encoder feedback from the servo motor is routed back through this board to close the position loop, enabling sub-micron positioning accuracy characteristic of FANUC servo systems.
Signal path: CNC CPU → Backplane Bus → A20B-1003-0090/05A → Servo Amplifier → Servo Motor → Encoder Feedback → A20B-1003-0090/05A (closed loop)
