Apparatus and Method for Monitoring Braking Power

A method for braking power monitoring and safety-related locking, of a drive of a technical system with two machine parts that are movable relative to one another and that are moved towards one another by the drive at a defined actuation interval, the method comprising:

• receiving of an encoder signal from an encoder coupled to a drive shaft of the drive at an input of a first controller;
• and
• outputting of an error signal at an output of the first controller based on processing of the encoder signal by the first controller,
• wherein the first controller determines a value for an acceleration from the encoder signal in response to a brake coupled to the drive shaft acting with its greatest possible braking force on the drive shaft of the drive and locks the drive in a safety-related manner in response to the determined value exceeding a limit value stored in the first controller.
