Servomotor module with OCT, 48 V
The servomotor EtherCAT plug-in module EJ7211-0010 with integrated One Cable Technology (OCT) offers
high servo performance in a very compact design for the motor types of the AM8100 series, up to 4,5 A (I
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 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, terminal temperature or motor load via the calculation of an I²T model, offer 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 module, we recommend using the module with Twin-
CAT 2.11 R3 or higher!
Mandatory hardware
The Module must be operated with a real-time capable computer and distributed clocks.
Approved motors
Trouble-free operation can only be guaranteed with motors approved by Beckhoff.
