7.4 Brake Relay
The Brake Relay is designed to provide the interface between the Power Module and the
brake solenoid of a motor. There are two types of Brake Relays:
● Brake Relay – this provides the basic braking control function.
● Safe Brake Relay – this provides for the braking control function within a safety integrated
system. To adhere to the requirements of a safety integrated system, the Safe Brake
Relay has been designed to allow a variable voltage to be given to the Safe Brake Relay
to allow the system to determine if the Safe Brake Relay is functioning correctly without
actually activating the braking function.
