Pulse motor control system

Abstract

Abstract PURPOSE:To prevent overshoot by providing ROM storing control program and slewing data for speed acceleration and deceleration, and obtaining phase switching timing pulse array through microprocessor. CONSTITUTION:ROM5 storing control program and ROM'S 6-1-6-3, 7-1-7-3 containing slewing data for speed acceleration and deceleration for plurality of target speeds are provided. Starting/stopping process routine for pulse motor 4 is executed by means of microprocessor 8, and is set at slewing circuit 10 through the intermediary of output 9. Then it is applied to phase switching circuit 3, switching and controlling electric current at excitation winding of pulse motor 4. Consequently, it is possible to reach target speed in a brief period of time, eliminating overshoot on account of the optimized operation against plural target speeds.
