Abstract
According to a motor control device, an operation of one of multiple motors is feedback-controlled based on a target speed signal corresponding to a predetermined target travel speed of a driven object driven by the one motor, or based on the target speed signal and a target position signal corresponding to a target travel position of the driven object related to the one motor. Based on operation information (current travel speed and/or current position) of the driven object driven by the one motor, other motor is feedback-controlled in accordance with a target travel speed and/or a target travel position of a driven object driven by the other motor with respect to the operation information. Thereby, the operation of the other motor is controlled to follow a possible operation variation (speed variations of the motor and the driven object, and/or a position variation of the driven object driven by the motor) related to the one motor. In this manner, an intended speed ratio and/or an intended positional relationship between the driven objects are precisely kept.
