CONTROLLING DEVICE OF STEPPING MOTOR

摘要

PURPOSE:To facilitate the control of a motor by providing a fixed memory cell feeding exciting data and a register serving as the address input of the fixed memory cell by loading the above data in a stepping motor driving device. CONSTITUTION:A fixed memory cell 1 is an ROM for example and the exciting data of an exciting pattern for a stepping motor 2 is read in the fixed memory cell 1. The ROM1 receives an address input consisting of a signal E sensing the presence of an exciting output, a signal D instructing foreward and reverse running and a register output B to generate exciting data C. A register 3 loads the data output C from the ROM1 whenever a driving periodic signal A for the stepping motor 2 arrives at the register 3 and the address input to the ROM1 is changed by varying the register output to change the data output C. A driving circuit 4 drives the stepping motor 2 in accordance with the data output C.
