TheBeckhoff I/O system is an I/O solution for highly-dynamic positioning tasksonto the market. The EL7201servo terminal with resolver interfaces features a compact design, whileoffering high servo-performance. The integrated fast control technology, with a field-oriented current and PI speed control, supports highly dynamic positioning tasks. Apart from thedirect connection of motor and resolver, the connection of a motor holdingbrake is also possible.

Permanentmagnet synchronous motors with a rated current of up to 4A can be connected as loads. The monitoring of numerous parameters, such asovervoltage and undervoltage, overcurrent, terminal temperature or motor load,offers maximum operational reliability. Modern power semiconductors guaranteeminimum power loss and enable feedback into the DC-Link when braking.

The servoterminal is fully integrated into the Beckhoff automation software TwinCAT,enabling convenient parameterisation. In the case of third-party masters,parameterisation takes place via the CAN over EtherCAT profile (CoE).

The servoterminals cover a broad range of positioning tasks: from packaging and assemblymachines to small robots. With the EL7201 servo terminal, the range of servo drives fromBeckhoff becomes even more finely scalable: from the miniature servo drive upto 200W in the EtherCAT Terminal format to the AX5000 Servo Drive with 118 kW.
