ABSTRACT:
If a traveling speed of a carriage calculated by a speed converter is larger than an estimated speed in a deceleration section, braking is conducted by a braking method corresponding to a manipulated variable generated by a drive control unit. Owing to this type of braking, the traveling speed is reduced to the estimated speed. At this time, braking is conducted corresponding to an error between a target speed and the traveling speed, or an error between a speed (corresponding to an error between a current position of the carriage and a target stop position) and the traveling speed. Therefore, even if a braking force required for braking differs depending on individual variability of the carriage control device or operative condition of the carriage, braking can be conducted with a suitable braking force.
