Servomotor terminals, 48 VDC

The servomotor EtherCAT Terminals EL7201 (MDP742 profile, 48 VDC, 2.8 Arms) / EL7201-0001 (DS402 profile, 48 VDC, 2.8 Arms) and EL7211 (MDP742 profile, 48 VDC, 4.5 Arms) / EL7211-0001 (DS402 profile, 48 VDC, 4.5 Arms) with integrated resolver interface offer high servo performance with a very compact 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 an 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.
