Softstop
Softstop is a term used to describe a mechanism or technique that prevents abrupt cessation of motion by introducing a controlled deceleration or a cushioning element before a moving part reaches a physical limit. It can be realized as a mechanical cushion at the end of travel or through drive-level control that slows the axis before contact with an end stop.
Mechanical implementations include elastomer or polymer cushions, springs, dampers, or compliant mounts that absorb energy and
Applications are common in CNC machines, robotics, and other precision equipment where end-of-travel contact can induce
Advantages of soft stops include reduced peak forces, lower vibration and noise, diminished wear on guides
