Axis Control Board – OKUMA 1911-1114
The 1911-1114 is an axis control board (“Axis Board”) manufactured by OKUMA Corporation, a component of the OSP (Open System Platform) CNC control system fitted to OKUMA machining centres and CNC lathes. The board manages the position and velocity regulation loops for the servo axes (X, Y, Z and additional axes), interfacing between the main CNC CPU and the servo drives. Multiple hardware revisions may exist; compatibility must be verified against the specific OSP generation of the machine.
The axis board is the electronic controller that closes the position and velocity loops on the machine’s servo axes: it receives position references from the CNC CPU and maintains accurate trajectory throughout machining. Failure of this board causes the immediate blocking of one or more axes, rendering the machine completely unusable until it is replaced or repaired.
OKUMA Corporation, founded in 1898 in Nagoya (Japan), is one of the world’s leading manufacturers of CNC machine tools (lathes, machining centres, grinding machines) and OSP-series CNC control systems. The 1911-1114 board belongs to a mature generation of OSP control; the product is legacy / discontinued: available only as used, surplus, or through specialist repair.
