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 
 for more information.
