EL7211-9014 | EtherCAT Terminal, 1-channel motion interface, servomotor, 48 V DC, 4.5 A, OCT, suitable for STO applications

The EL7211-9014 servomotor EtherCAT Terminal with integrated One Cable Technology (OCT) offers high servo performance in a very compact design for motors from the AM8100 up to 4.5 A (I_rms). The One Cable Technology combines a motor cable and an absolute feedback system in a single cable. The integrated electronic type plate of the AM81xx motors can be read in automatically by the servo terminal to configure the motor parameters automatically. Thus, wiring and commissioning expenditure are minimized.

The fast control technology, based on field-orientated current and PI speed control, supports fast and highly dynamic positioning tasks. The monitoring of numerous parameters, such as overvoltage and undervoltage, overcurrent, terminal temperature or motor load via the calculation of a I²T model, offers maximum operational reliability. EtherCAT, as a high-performance system communication, and CAN-over-EtherCAT (CoE), as the application layer, enable ideal interfacing with PC-based control technology. The latest power semiconductors guarantee minimum power loss and enable feedback into the DC link when braking. 16 LEDs indicate status, warning and error messages as well as possibly active limitations.

The STO function according to EN 61800-5-2, can be implemented using the reaction-free HWE input corresponding to a safety level Cat. 3, PL d according to DIN EN ISO 13849-1:2015 (see document "EP7211-0034 | TwinSAFE application example").
