SPS IPC Drives | EtherCAT servo terminals

The servo terminals in the Beckhoff EtherCAT Terminal system integrate a complete servo drive to facilitate highly dynamic positioning tasks in a standard I/O terminal housing. With the new versions, a higher output current and STO (Safe Torque Off) safety functionality is now available in an extremely compact terminal design for DIN rail installation.

Compact drive technology

The small drives in the low-voltage range offer solutions for both conventional operation and operation without a control cabinet.

EL7221-9014 | EtherCAT Terminal, 1-channel motion interface, servo motor, 48 V DC, 8 A, OCT, suitable for STO applications


The EL7221-9014 servomotor EtherCAT Terminal with integrated One Cable Technology (OCT) offers powerful servo performance in a very compact design for motors from the AM8100 series up to 8 A (Irms). OCT combines a motor cable and an absolute feedback system in a single cable. The integrated electronic type plate of the AM81xx motors can be read in by the servo terminal to configure the motor parameters automatically. Thus, commissioning of the motors as well as cabling are minimised. The high-performance control technology supports fast and highly dynamic positioning tasks. Monitoring of numerous integrated parameters offers maximum operational reliability. The specified output power is attained in operation with the ZB8610 fan cartridge. For operation without a fan cartridge, the EL7211-9014 is recommended. The EL7221-9014 enables the user to implement the safety function STO (Safe Torque Off) that corresponds to a Cat 3, PL d safety level according to EN ISO 13849-1:2015.
