Slimmed down servo control

22 March 2011

The incredibly thin new servo controller from Beckhoff - measuring just 12mm wide - was displayed at SPS/IPS/Drives. The 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 and reduces spatial requirements and costs.

This latest offering sees Beckhoff bring an I/O solution for highly-dynamic positioning tasks onto the market 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, says the company.

The servo terminals can undertake a broad range of positioning tasks - from packaging and assembly machines to small robots. Permanent magnet synchronous motors with a rated current of up to 4 A 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.
