ABSTRACT:
In a method of controlling a movable member in a molding machine, a speed of movement of the movable member which is moved by driving device is detected, the speed of movement thus detected, and a deceleration time which is required for decelerating the movable member so that the movable member is stopped or nearly stopped, are utilized to obtain an over-run distance from a braking start position provided for the movable member, the braking start position is set to the over-run distance which is just short of a movement limit position provided for the movable member, and braking control is started for the driving device when the movable member reaches the braking start position, whereby the collision of the movable member against the stationary member is prevented, or, when the former collides with the latter, the impact is less.
