Beckhoff's servo terminal: a complete drive in a compact EtherCAT Terminal
The EL7201 servo terminal for the Beckhoff EtherCAT Terminal system integrates a complete servo drive for motors up to 200 W in its housing. Integration into the EtherCAT I/O system considerably simplifies wiring and commissioning effort, while also reducing space requirements and costs.
The servo terminal extends the Motion product range of the Beckhoff I/O system: in addition to its I/O terminals for stepper motors, AC motors and DC motors, Beckhoff now offers a solution for more dynamic positioning tasks. The EL7201 servo terminal with resolver interface is a model that is both very compact and high-performing. With fast control algorithms and a PI current and speed control loop, it supports highly dynamic positioning tasks. In addition to the direct connection of the motor and resolver, the motor brake can also be controlled.
This terminal can control permanent-magnet synchronous motors with a rated current of up to 4 A. Numerous monitoring functions, such as overvoltage and undervoltage, overcurrent, terminal temperature and motor load, provide maximum operational reliability. Modern power semiconductors ensure low power dissipation and allow energy to be fed back into the DC link during braking.
The servo terminal is fully integrated into the Beckhoff TwinCAT automation software and allows simple parameterization. For third-party EtherCAT masters, parameterization is carried out via the CAN-over-EtherCAT (CoE) profile.
Scalable servo solution
The servo terminals cover a wide range of positioning applications: from packaging machines to mini robots, including assembly robots. The EL7201 servo terminal allows our range of drives to be scaled even more finely: from the smallest 200 W drive in the EtherCAT Terminal to the AX5000 drive of 118 kW, Beckhoff offers a wide range, as well as servo motors.
