Abstract
Systems and methods for providing Safe Torque Off signals using communication wires used for control signaling. Single channel Safe Torque Off signals can be provided as a DC voltage or AC voltage across two sets of twisted pair wires. Alternatively, two Safe Torque Off signals can be provided using both a DC voltage and an AC voltage across the two sets of twisted pair wires.
