Beckhoff EL7211-0010 EtherCAT Terminal

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.

Connections and Interfaces

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.

Compliance and Certifications

• CE: Conforms to European EMC and Low Voltage Directives.
• UL: UL listed for industrial control equipment.
• EMC Immunity/Emission: Conforms to EN 61000-6-2 and EN 61000-6-4.
• Vibration/Shock Resistance: Conforms to EN 60068-2-6 and EN 60068-2-27.
