“B” Group: Fine-Tuning Functions

External Brake Control

The brake control function in the inverter controls external braking used in systems such as elevators. The purpose of this function is to ensure the inverter is powering the motor before releasing external brakes that would permit the load to move or coast. This function requires the configuration and wiring of intelligent input and output terminals. See “External Brake Control Function” on page 4–39 for more information.
