ABSTRACT:
A stepping motor control system according to the present invention includes a counting mechanism for counting the number of steps of the pulse train command, a latch mechanism for holding a counting value of the counting mechanism with a latch signal and finding a position command, a reference signal generating mechanism for generating the latch signal and a reference clock signal, a first calculating mechanism for calculating a pulse spacing of the pulse train command with the reference clock signal, and a second calculating mechanism for calculating a time interval from generation of the pulse train command to generation of the latch signal with the reference clock signal. In the stepping motor control system, the position command is corrected using command pulse spacing information calculated by the first calculating mechanism and time difference information calculated by the second calculating mechanism.
