ABSTRACT:
The inventive system for controlling a working shaft includes a layout for the time to number conversion, wherein a divider is provided to divide with use of a pulse rate outputted from the memory storage, and the shaft driver is operated by output from such a divider and is thereby controlled with use of the data stored in the memory storage. Concurrently, by introducing the counter outputs indicating the time scaling into the addresses of a memory sector, the memory sector is arranged to output varying speed data corespondent to the time scaling data. Thereby trailing actions of the working shaft to trace a given locus are determined by data stored in the memory storage, which enables a complex real time control to be feasible by the inventive simple control system, wherein, as required, a change in the control specification is simply made by a change of data in the memory storage.
