Servo Drives

They expand theBeckhoff portfolio of compact drive technologyin I/O terminal format and offer all of the current technology features together with increased performance and functionality compared with comparable EL series I/O designs.

The ELM72xx modules’ metal housings provide optimum heat dissipation even at high output power as well as optimal shielding against electrical interference. The new servo terminals can connect directly to other EtherCAT Terminals as an integrated component of the Beckhoff I/O system. The comprehensive functionality includes the direct connection of the motor, feedback and brake via the convenient connector front end, an integrated absolute value interface and One Cable Technology (OCT).

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 comprehensive package of Safe Motion functions for safety-relevant drive technology via TwinSAFE.

Five different ELM72xx models equipped with either STO/SS1 or Safe Motion are currently available:
•ELM7211: 1-channel servo terminal with 4.5 A (Irms)

•ELM7212: 2-channel servo terminal with 2 x 4.5 A (Irms)

•ELM7221: 1-channel servo terminal with 8 A (Irms)

•ELM7222: 2-channel servo terminal with 2 x 8 A (Irms)

•ELM7231: 1-channel servo terminal with 16 A (Irms)

In contrast to the established EL series I/O terminals, the ELM72xx wiring level utilizes a pluggable design. Matching motor and sensor cables further simplify installation. The drive design – ELM72xx combined with AM8100 Servomotors – is implemented using the familiar TwinCAT 3 Motion Designer software (TE5910). The electronic nameplate and the TwinCAT 3 Drive Manager 2 software (TE5950) ensure efficient commissioning.
