PURPOSE:To realize an operational pattern optimal for the characteristic of load by setting the operational pattern freely in a digital system through a memory and a timer. CONSTITUTION:Upon elapse of time T1 after start of a motor 11 through depression of a motor start command button 1, a timer 2a functions and an AND gate 4a provides a digital value proportional to the rotation from a memory 3a to a D/C converter 6 thus providing a required rotation command K1 to a speed controller 10. Upon elapse of time T2, a timer 2b functions to turn the output signal from the AND gate 4a OFF, while a second stage AND gate 4b operates to provide a digital value proportional to the rotation from a memory 3b to the D/A converter thus providing a rotation analog value K2 to the speed controller 10. In similar manner, a rotation analog value Kn is provided to the speed controller 10 upon elapse of time Tn and a motor 11 is controlled in a predetermined rotary pattern. |
