Abstract
In a motor control system including a clock pulse generator, use is made of the clock pulses for deriving digitally, the speed-above-normal signal, the starting signal, the brake-release signal and the normal or forward rotation signal for displaying the normal or forward rotation. In response to the starting signal, 100% torque control voltage is generated and in case of the forced reversal in rotation, 100% torque control voltage for preventing the rotation in the reverse direction is generated.
