Position defining system has position defining module movable along bearer rail and with stop that can be deployed in path of motion of moving element or retracted out of its path

摘要

The system has a bearer rail on which at least one position defining module (26) is mounted to be movable along the rail and releasably fixed to the rail in different working positions. The adjustment direction (36) is parallel to that of a moving element (5) coupled to a drive output element of the linear drive. The module has a stop (42) that can be deployed in the path of motion of the moving element or retracted out of its path.
