Compact I/O Terminal for Servo Motor Control

Nov. 1, 2011
The EL7201 servo terminal for the EtherCAT Terminal system integrates a complete servo drive for motors up to 200 W into a standard 12 mm I/O terminal housing.
Integration into the EtherCAT I/O system considerably simplifies cabling and commissioning, while reducing cabinet size requirements and costs., according to the company. This product is as an addition to the company’s line of terminals for stepper motors and AC and DC motors. The EL7201 servo terminal with resolver interfaces features an exceptionally compact design, while at the same time offers high servo performance. The integrated fast EtherCAT control technology, with field-oriented current and PI speed control, supports highly dynamic positioning tasks. 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 servo terminal is integrated into TwinCAT automation software for convenient parameterization. In the case of third-party masters, parameterization takes place via the CAN over EtherCAT profile (CoE).Beckhoff Automation
