The new EL7201 servo terminal for the Beckhoff EtherCAT terminal system integrates a complete servo drive for motors up to 200 W into a standard I/O terminal housing. Integration into the EtherCAT I/O system simplifies cabling and commissioning considerably and reduces spatial requirements and costs.
The terminal expands the range of compact drive technology solutions for the Beckhoff I/O system: as an addition to the popular terminals for stepper motors and AC and DC motors there is now a solution for highly-dynamic positioning tasks. The EL7201 servo terminal with resolver interfaces features a compact design, while at the same time offering high servo-performance. 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 4 A can be connected as loads. The monitoring of parameters, such as voltage, current, terminal temperature and motor load is offered for 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.
