Beckhoff Servo terminals with safe torque off functionality
EL72x1-9014 EtherCAT servo terminals implement safe torque off (STO) functionality. The integrated features correspond to safety level Cat. 3/PL d, according to EN ISO 13849-1:2015. The I/O terminal form factor promotes space-saving motion solutions via advanced servo drive technology with built-in safety functionality and One Cable Technology, which combines power and feedback signals to servo motors into one standard cable. Two-channel shut-off with corresponding contactors in the motor cable reduces cabling effort and space requirements as a single cable connects the TwinSafe safety output terminal (e.g., EL2904) and the STO input of the servo terminal.
