Description
Designed for space-restricted motion control applications, the Beckhoff EL7211-0010 is a compact, high-performance servomotor EtherCAT Terminal featuring integrated One Cable Technology (OCT). This single-channel motion interface enables direct connection of permanent magnet-excited three-phase synchronous motors up to 4.5 A (RMS) at 48 V DC. By combining power and feedback lines into a single cable, the module significantly reduces wiring complexity, installation space, and overall system costs. The terminal integrates high-speed current, speed, and position control loops, delivering dynamic positioning capabilities directly within the modular EtherCAT I/O system.
Features
- Single-channel compact drive technology for permanent magnet-excited three-phase synchronous motors.
- Supports One Cable Technology (OCT) for simplified motor connection and absolute feedback.
- Delivers a continuous output current of 4.5 A RMS, with a peak current capacity of up to 9.0 A for 1 second.
- Integrated 24 V DC motor brake control output rated up to 0.5 A.
- Equipped with 2 end position inputs and 1 feedback interface.
- Supports Distributed Clocks (DC) for precise, microsecond-level synchronization across the EtherCAT network.
- High-density (HD) housing design with integrated signal LEDs for real-time status diagnostics.
Applications
- Packaging and labeling machinery.
- Pick-and-place assembly systems.
- Automated material handling and conveyor systems.
- Robotic joint positioning and small-scale gantry systems.
- Semiconductor manufacturing equipment.

Installation Guidelines
-
Mounting: Mount horizontally on a standard 35 mm DIN rail conforming to EN 60715. Secure using the integrated locking mechanism.
-
Side-by-Side Installation: Align terminals side-by-side using the double slot and key connection system to ensure reliable E-bus communication.
-
Shielding and Grounding: Ensure the DIN rail is properly grounded to a low-impedance reference point. Use shielded motor cables to minimize electromagnetic interference (EMI).
-
Ventilation: Maintain adequate clearance above and below the terminal block to allow natural convection cooling, keeping the operating temperature below +55 degC.
