Abstract

PURPOSE:To select the desirable adjustable speed operating locus optionally by a method wherein pulse rows obtained by serially reading a bit parttern memorized to a memory are frequency-divided, the quantity of displacement is reduced and a motor is driven. CONSTITUTION:A bit pattern that can gain an adjustable speed operating locus is memorized to a memory 2, the pattern is serially read by means of an address counter 5, and a motor M is driven every minute unit quantity through a variable frequency divider 3 and a drive circuit 1. A variable frequency divider 6 is operated by data from a reduction rate memory 14 when the quantity of displacement is little, and time is shortened by increasing scanning frequency while drive pulses, whose quantity of displacement is reduced, are generated by frequency-dividing pulse rows. Thus, an adjustable speed operating locus of the motor M is freely selected by arbitrarily choosing the bit pattern of the memory 2 while the locus can be changed extremely simplly.
