ABSTRACT:
A method and system for altering the phase difference between a local motor and a remote motor wherein the phase difference is determined in terms of a count made of reference pulses at a first frequency when both motors are operating at a predetermined speed that is directly related to the first frequency. A phase altering count is determined from the phase difference count indicative of the degree to which the phase difference is to be altered and the reference pulses are produced at the local motor at a second frequency to alter the speed of the local motor. The phase altering count and the reference pulses at the second frequency are used to establish a time interval for operation of the stepping motor sufficient to make the desired change in the phase difference.
