Brake Relay (Optional)
The Brake Relay connection (on the Output Power connector) provides a
safety feature for your motion control system, particularly for vertical
applications. The drive/controller acts as a control switch for the motor brake
(if a brake is present). When 24V is applied from an outside power supply
through the drive’s Brake Relay (BK) terminals, the motor brake is disabled.
When the power supply is interrupted, or the drive/controller faults or is
disabled, the brake is enabled and stops shaft rotation.
