ABSTRACT:
A motor rotation control device furnished with a rotational detector for detecting the rotation of the motor and actual rotation direction detecting means for obtaining the actual direction of rotation of the corresponding motor on the basis of the rotation detection signals of the corresponding rotational detector and so composed that reverse drive force can be given to the corresponding motor by changing a commanding signal for appointing the direction of rotation of the corresponding motor when changing the direction of rotation of the corresponding motor or braking the motor, wherein any error of the motor rotation control device can be instantaneously detected, without waiting until the above actual direction of rotation of the motor becomes coincident with the rotation commanded direction after changeover, even right after the rotation commanded direction of motor by a commanding signal has been changed.
