Information About EL7211
The Beckhoff EL7211 is a compact EtherCAT servo motor terminal designed to deliver high-precision control for synchronous servomotors in automation systems requiring dynamic performance. It integrates a resolver interface to support motors of the AM8100 and AM3100 series, enabling accurate speed and position feedback. With a continuous current rating of 4.5 A and a peak of up to 9 A, the terminal provides ample power for highly responsive motion tasks. Its fast field-oriented current control and advanced PI speed controller ensure smooth operation and excellent dynamic behavior. Additional safety and monitoring features—such as overvoltage, undervoltage, overcurrent, and thermal protection—provide increased operational reliability. Designed with distributed clock support and CAN-over-EtherCAT (CoE) communication, the EL7211 allows seamless integration into PC-based control systems, making it ideal for demanding motion applications within compact EtherCAT environments.
Key Features
- Integrated Servo Drive Terminal: Combines motor control, resolver feedback, and motion processing into a single EtherCAT terminal for compact system design.
- High-Dynamic Motion Performance: Uses field-oriented current control and PI speed regulation for fast, precise positioning in automation tasks.
- Resolver Feedback Integration: Ensures accurate motor position and speed measurement, ideal for synchronous servomotors in high-precision applications.
- Flexible 48 V Power Stage: Supports power inputs from 8 to 48 V DC and outputs continuous current up to 4.5 A, with peaks reaching 9 A.
- Advanced Protection and Monitoring: Includes overvoltage, undervoltage, overcurrent, temperature, and load monitoring for increased system safety.
- Distributed Clocks Support: Ensures synchronized motion across multi-axis EtherCAT systems, improving accuracy and performance.
- Energy-Efficient Control: Uses modern semiconductor technology for minimal power loss and supports regenerative energy feedback into the DC link.
- Compact Industrial Design: Lightweight, space-efficient EtherCAT terminal with IP20 protection and wide operating temperature support.
The EL7211 delivers the reliability and precision required for advanced servo motion control in EtherCAT-based automation architectures.
