Filed: 1989-03-30
Abstract: PURPOSE:To increase a speed for a constant-speed operation as much as possible by determining a constant-speed period through changing according to the number of steps a boundary value for an adjustable-speed stepping motor to store for performing said constant speed operation. CONSTITUTION:When a motor operation is demanded from a keyboard 16 through a port latch 13, a CPU 10 starts the motor operation program of a ROM 11, outputs a motor-driving pulse to the port latch 13, and drives a stepping motor 15 through a motor driver 14. When said motor 15 is accelerated to reach a specified speed, the value of said speed is stored in a RAM 12 as a boundary value and a constant-speed rotation is continued. When the keyboard 16 is operated to change the number of steps, said value is stored in the RAM 12 as a new boundary value, a constant-speed period is determined by the program of the ROM 11, and said constant speed rotation changes to that with the new number of steps. Thus, a speed for a constant-speed operation rises as much as possible according to the number of steps.
