Holding Brake Wiring Diagram - Leadshine EL8-EC Series User Manual

2.7.1 Holding brake wiring diagram

Holding brake is activated when servo drive is not powered on to prevent axis from
moving due to gravitational pull or other external forces by locking the motor in place.
Usually used on axis mounted vertically to the ground so that the load would not drop
under gravitational force when the driver is powered off or when alarm occurs.
EL8 series servo drives support direct drive holding brake. Please connect BR+ and BR-
to an external 24v power supply and motor brake terminal to control the holding brake.
There is no need for an external relay.
1. Using internal holding brake output port X3 (Easy wiring, no need for an extra relay)
