Abstract

PURPOSE:To smoothly permit the starting and the halt of step motor by a method wherein the excitation phase switching time of the step motor for the rise time and the fall time is previously stored as data in the memory element such as the read only storage or the like. CONSTITUTION:The binary-coded value of the excitation time of 1 step divided by the cycle of the clock b is stored in ROM2. The counters 1, 3 are set by the output j of the flip-flop 5 which is set by the starting signal a, and the ROM2 is read out by means of the address signal d of the counter 1. The output e is counted up at the counter 3 by means of the clock b to emit the carry signal f. The signal f develops into the signal g synchronized with the clock c through the D flip-flop 4 to enter the counter 6. And the step motor 8 is accelerated according to the data of ROM2. In case of the reduced speed time, the sequence of read of ROM2 becomes reverse.
