) and EL7211-0010 (50V

)
with integrated absolute value interface offer high servo performance with a very compact design. The
EL72x1-0010 was designed for the motor types of the AM81xx series from Beckhoff Automation.
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.
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.
Note
Recommended TwinCAT version
In order to be able to utilize the full power of the EL72x1-0010, we recommend using the
EL72x1-0010 with TwinCAT 2.11 R3 or higher!
Note
Mandatory hardware
The EL72x1-0010 must be operated with a real-time capable computer and distributed
clocks.
Note
Approved motors
Trouble-free operation can only be guaranteed with motors approved by Beckhoff.
