8 . Controlling and/or regulating device for a lifting table ( 10 ) supporting a continuous casting mold ( 5 ) in a continuous casting machine ( 1 ) for liquid metal, in particular for liquid steel material ( 3 ), comprising an oscillating drive ( 11 ) which transmits upward motion and downward motion to the lifting table ( 10 ) and the continuous casting mold ( 5 ), which upward and downward motion being generated by a plurality of stationary piston-cylinder units 912 ) which are articulated at the lifting table ( 10 ); local measuring devices ( 16 ) for each piston-cylinder unit ( 12 ) in form of, respectively, a valve block ( 17 ) with a regulating valve ( 18 ) and a plurality of pressure transducers ( 19 ), and in form of a position sensor ( 20 ); hydraulic cylinder ( 12 a ) and an elevated control/regulating stations,
characterized in that
in the vicinity of the lifting table, an axle-regulator ( 31 ) with a microprocessor is provided, wherein an application software runs on the microprocessor for regulating the movement of axes in form of separate piston-cylinder units of the lifting table in real time, and in that the application software is adaptable to the respective type of the separate piston-cylinder units and the type of the position feedback by parameters.
9 . Controlling and/or regulating device according to claim 8 , characterized in that the application software is formed to control the movement of the piston-cylinder units in accordance with signals of the field measuring devices and in accordance with reference values and a starting movement which were preset from the elevated control and/or regulating station ( 25 ) in the axle regulators ( 21 ) via a fieldbus line ( 22 ).
