Claim 4:
5. A motor control system comprising:
host control circuitry configured to generate a control command;
a plurality of motor control apparatuses configured to control a plurality of motors, respectively, based on the control command;
a plurality of sensors each of which is configured to detect position information of a movable part of each of the plurality of motors to output the position information to each of the plurality of motor control apparatuses;
each of the plurality of motor control apparatuses comprising information sharing circuitry configured to share the position information among the plurality of motor control apparatuses via data communication; and
at least one of the plurality of motor control apparatuses comprising:
reaching determination circuitry configured to determine whether a reference point of a drive machine driven by the plurality of motors reaches a predetermined position based on the position information; and
a trigger output circuitry configured to output a trigger signal when it is determined that the reference point has reached the predetermined position.
