ABSTRACT:
A motor control system for controlling a plurality of motors for moving an object in respectively different axial directions that includes a plurality of target devices, each target device including a (pulse width modulation) PWM signal generator that generates a PWM signal for driving a motor using a triangular signal, and a host device for supplying a synchronization signal to each of the target devices, wherein each target device is arranged with a corresponding motor, and each PWM signal generator resets the triangular signal in response to the synchronization signal.
