Abstract
A method and system for mitigations brake failure in a medical device. The method and system includes a motion system for at least one movable load. Each movable load has a drive, a controller for the drive, and a brake. The controller is adapted to monitor positional parameters of the drive or electrical parameters of the brake or a combination of both. The method involves the step of monitoring the parameters and evaluating the parameters to detect a brake failure of the brake.
Claims22
A medical device, comprising:
- a motion system, for at least one movable load, comprising:
- for each movable load:
- drive means;
- control means for the drive means;
- and
- brake means,
- wherein the control means is adapted to detect a brake failure of the brake means by monitoring positional parameters of the drive means or electrical parameters of the brake means or a combination of both, and
- wherein upon detection of a brake failure the drive means is placed in a balance state such that gravity will not cause the load to move.
