Direct Connection of Servomotor and Resolver to EtherCAT Terminal

The Beckhoff I/O system is an I/O solution for highly-dynamic positioning tasks onto the market. The EL7201 servo terminal with resolver interfaces features a compact design, while offering high servo-performance. The integrated fast control technology, with a field-oriented current and PI speed control, supports highly dynamic positioning tasks. Apart from the direct connection of motor and resolver, the connection of a motor holding brake is also possible.

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

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