Wiring the SBC output
This function only guarantees that the power supply for the mechanical brake is correct. It cannot detect brake
wear. Check the mechanical brake periodically to ensure it is functioning correctly.
To use SBCS (SBC output), connect it to the electromagnetic brake of the servo motor. Wire the system so that the
electromagnetic brake activates when SBCS (SBC output) turns off. There is no need to use the MBR (Electromagnetic brake
interlock) of the servo amplifier. For information on the operating sequence when using the SBC function, refer to "SBC
function" in the following manual.
