3.4 Wiring for SBC output

SBCS (SBC output) can be used by being connected to the electromagnetic brake on the servo motor. Wire
it so that the electromagnetic brake operates when SBCS (SBC output) turns off. Using MBR of servo
amplifier (electromagnetic brake interlock) is not necessary.
Refer to section 4.5.6 for the operation sequence for when using SBC function.

Note 1. Create the circuit in order to shut off by being interlocked with the emergency stop switch.
2. Do not use the 24 V DC interface power supply for the electromagnetic brake.
POINT
This function guarantees only that power to mechanical brake is properly
supplied, and abrasion of the brake cannot be detected. Check this function
regularly that the mechanical brake can operate.
