PURPOSE:To control the drive of a motor at quick response by command instructions, control the motor at fixed speed and stop the motor accurately in the prescribed quantity of movement corresponding to the instructions by a method wherein the revolution and movement of the motor are digitally detected, and speed is controlled by using a microprocessor. CONSTITUTION:A deviation counter 6 puts out drive signals until instruction signals and detecting signals of an encoder 4 equalize every time the instruction signals from a signal input device 5 inputting and setting the command are inputted, and turns a motor 1. The instruction signals and the detecting value of the encoder agree and the motor 1 is stopped when necessary revolution and the controlling of a location are conducted, but the drive signal are controlled at speed corresponding to instructions by the arithmetic controlling of a CPU8, and the deviation of speed is detected by signals detected by means of the encoder 4, the duty of the drive signals is altered by the offering arithmetic processing of the CPU8 when the deviation exceeds a stationary range, and the motor is controlled at the stationary speed of revolution. |
