Beckhoff ELM72xx Series integrates servo drives in the EtherCAT I/O system.
Beckhoff released its ELM72xx EtherCAT Terminals, fully functional servo drives in metal housings that deliver an output current (Irms) of up to 16A at 48VDC for the power supply. The servo terminals can connect directly to other EtherCAT Terminals and provide the direct connection of the motor, feedback and brake via the connector front end, an integrated absolute value interface and One Cable Technology (OCT). Additional I/Os enable latching of position values. In addition, the integrated brake chopper control permits direct connection of braking resistors. The system also integrates programmable TwinSAFE Logic for direct implementation of the safety application in the terminal and safe drive technology either as STO/SS1 via Safety over EtherCAT (FSoE) or as a package of Safe Motion functions for safety-relevant drive technology via TwinSAFE. The line’s five ELM72xx models are equipped with either STO/SS1 or Safe Motion.
