Abstract
A motor control system comprises a plurality of control apparatuses and a host control apparatus, wherein each of the control apparatuses include a position control unit controlling position based on a position command and commanded speed from the host control apparatus, a speed control unit controlling speed based on a speed command from the position control unit, a current control unit controlling current based on a current command from the speed control unit, and a current amplifier which amplifies motor driving current based on a voltage command from the current control unit, and wherein the current control unit includes a voltage saturation processing unit which determines whether the voltage command has exceeded supply voltage of the current amplifier, and which outputs the result of the determination, and a voltage saturation notifying unit which notifies the host control apparatus of the result of the determination made by the voltage saturation processing unit.
