design. The EL72x1 was designed for the motor types of the AM31xx and 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.
Recommended TwinCAT version
In order to be able to utilize the full power of the EL72x1, we recommend using the EL72x1
with TwinCAT 2.11 R3 or higher!
Note
Mandatory hardware
The EL72x1 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.
