PURPOSE:To operate effectively a storage device and to reduce the load of an operator by performing the teaching operation of a system with composite data inputted just before if it is discriminated that one of two kinds of teaching data is not changed as the result of the comparison with teaching data inputted just before. CONSTITUTION:Position detection information given from a position detecting means such as a pulse encoder 7, which detects the position, for example, of a mold, to a distributing board 11 is transmitted to a communication board 13. Position detection information given from the communication board 13 and comparison information of position detection given from a comparator 21 are inputted to a CPU19. The comparator 21 compares position detection information given from a temporary storage buffer 27 for D axis on a basis of a driving command signal with that given from a step (i) storage buffer 35 for D axis. Only when they do not coincide with each other, a signal is outputted to the CPU19 to transfer data stored in the buffer 27 to a teaching data storage area (RAM)39 by a switching element 37; and thus, the RAM area is used efficiently, and the number of times of correction of present position data of the mold is reduced considerably. |
