Safe Brake Test (SBT)

Using the "Safe Brake Test" function can significantly increase safety. If the wearing, mechanical part of the brake is not maintained regularly, it cannot be guaranteed that the holding brake will apply the designated braking action in the event of danger.

The "Safe Brake Test" function checks the functions of the brake. The brake test may be carried out in each production cycle or only every 8 hours, depending on the specific application and the requirement from the risk analysis. During the test the brake is loaded with additional torque. If the position changes during testing, this is identified as an inadmissible state and results in a message that prevents further operation. The plant is shut down safely to allow the brake to be repaired.  This reduces maintenance work considerably.
