The manual says: Internal dynamic braking switch has been overloaded. Trying to decelerate a large inertia load too quickly or too often

To clear a brake switch alarm, you will need to start with the dynamic braking calibration and verify that it is properly set up, next you need to examine the installation to make sure the load isn't too much for the dynamic braking system. It is possible to overheat the dynamic brake circuit if you are stopping the motor too often also... so there are few places you need to visit when you see this alarm.
