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.
The LEDs indicate status, warning and error messages as well as possibly active limitations.
With the One Cable Technology (OCT) the encoder cable is omitted by transmitting the signals of the
encoder digitally via the existing motor cable. The option to read the electronic type plates of suitable motors
from the AM81xx series enables a plug-and-play solution for maximum convenience during commissioning.
The EL72x1-901x provides an STO input with which the motor connected to the terminal can be switched
torque-free. This STO input is connected to a safe output of an EL2904.
Performance Level d, Category 3 according to DIN EN ISO 13849-1:2015 is attained for the SFO safety
function of the EL72x1-901x together with an EL2904.
