The EJ7211-0010 EtherCAT plug-in module 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 (Irms).

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