PROBLEM TO BE SOLVED: To generate a speed command for utilizing the capacity of a carriage drive motor unit to the maximum. SOLUTION: The motor controller 16 for controlling a carriage drive motor 37 subjected to a load, e.g. a carriage 11, by delivering a command signal Z comprises a first operating circuit 51 for operating the maximum angular accelerationα0max of a carriage drive motor unit required for operating the carriage drive motor at a desired speed from the angular speedω0/angular accelerationα0 diagram of the motor unit, a second operating circuit 52 for operating the maximum angular speedαmax of the carriage drive motor under load while taking account of the maximum angular acceleration and the load of the motor unit, and a third operating circuit 53 for operating and altering the maximum angular acceleration of the carriage drive motor under load depending on the variation in the mass M of the carriage.
