Axis Positioning Control Board – FUJI EP-3308D-C
The EP-3308D-C is an electronic axis positioning control board (“Axis Positioning Control Board”) manufactured by FUJI Electric, belonging to the numerical control and industrial automation product family of the same manufacturer. The board processes position commands from the CNC CPU, compares them with axis encoder feedback signals, and calculates the speed reference to be transmitted to the drives. The series identifier EP-3308 designates the board family within FUJI’s positioning control range for this generation; the suffix identifies variant D and revision C.
The axis positioning board is the central element of motion control: it receives position commands from the CNC processor, compares them with the feedback signal (encoder or resolver), and calculates the following error to continuously correct the axis trajectory. Without this board, the CNC system loses complete control of the axes: any movement becomes uncontrolled, with consequent risk of collision, dimensional rejection of the workpiece, or serious mechanical damage to the machine.
FUJI Electric is a Japanese industrial group founded in 1923, with strong specialisation in power electronics, inverters, drives, CNC systems and industrial automation. Historically present in the machine tool market with proprietary axis control systems, the group has progressively oriented its offering towards new-generation integrated solutions. The CNC control modules and boards of this series are legacy / discontinued: available exclusively as used, surplus or through specialist repair.
