PROBLEM TO BE SOLVED: To securely protect a movable member before a mechanical stopper arrives, by providing an actuation device of motor-driven members in which an absolute actual value detector has a specified number of different positional ranges and also the detector transmits respective first signals in the beginning and last positional race and further, the beginning and last position al range has a larger size than the residual positional range. SOLUTION: An absolute actual value detector 11 has at least five different positional ranges A, B, C, D, E and transmits the first signal respectively in the beginning and last positional ranges A, E. The beginning and last positional range A, E where the first signal is transmitted from the absolute actual value detector 11 has a larger size than the residual positional ranges B, C, D. In this way, a movable member is decelerated before arrival of a mechanical stopper and a secure protection can be achieved. |
