Beckhoff EP7211-0034 EtherCAT Box 1 Channel Motion Interface

EP7211-0034 | EtherCAT Box, 1-channel motion interface, servomotor, 48 V DC, 4.5 A, OCT, suitable for STO applicationsPreferred type

The EP7211-0034 servomotor EtherCAT Box with integrated One Cable Technology (OCT) offers high servo performance in a very compact design for AM8100 series motors with up to 4.5 A (Irms).

The One Cable Technology combines motor cable and absolute feedback system in a single cable.

The integrated electronic identification plate of the AM81xx motors can be read in automatically by the servo box to configure the motor parameters. In this way, wiring and commissioning requirements are simplified.

The high-performance control technology supports fast and highly dynamic positioning tasks, while numerous monitoring functions offer maximum operational reliability.

EtherCAT as a high-performance system communication enables ideal interfacing with PC-based control technology.

LEDs indicate status, warning and error messages as well as possibly active limitations. 

Two integrated digital inputs enable the connection of limit switches.

The STO function according to EN 61800-5-2 can be implemented with the aid of the non-reactive HWE input according to a safety level Cat.

 3. PL d according to DIN EN ISO 13849-1:2015 (see document “EP7211-0034 TwinSAFE application example”).
