Abstract
Program storage means (1) is stored with a command program (1a) for driving and controlling a servomotor (4) that drives a belt conveyor (2). Acceleration-deceleration control means (7) detects the current position and current speed of the servomotor (4), and referring to the result of detection, executes acceleration-deceleration control in accordance with acceleration-deceleration points commanded by the command program (1a) and a time constant and target speed for each acceleration-deceleration point.
