Description

Designed for compact motion applications, the EL7221-9014 servomotor terminal integrates high-performance drive technology into a standard 12 mm EtherCAT Terminal format. This motion interface is engineered for the direct control of permanent magnet-excited three-phase synchronous motors (brushless AC servomotors) operating up to 48 V DC and up to 8 A. Featuring One Cable Technology (OCT), it combines motor power and feedback signals into a single cable, reducing wiring complexity and overall installation footprint. The terminal incorporates a hard-wired Safe Torque Off (STO) safety function, offering safe-stop capability matching standard industrial safety regulations.

Features

  • One Cable Technology (OCT): Integrates motor power lines and absolute feedback signals into a single cable interface.
  • Integrated Safety: Features hard-wired Safe Torque Off (STO) capability via safe output connection.
  • Synchronized Execution: Distributed Clocks support ensures high-precision synchronization within EtherCAT network systems.
  • Compact Design: Standard 12 mm High-Density (HD) housing optimized for side-by-side DIN rail mounting.
  • Brake Control: Built-in 24 V DC, 0.5 A motor brake output.
  • High-Frequency Control: 16 kHz PWM clock frequency paired with a 32 kHz current controller frequency for smooth motor performance.

Applications

  • Decentralized servo drive positioning systems.
  • Pick-and-place packaging and assembly machinery.
  • Robotic handling systems.
  • High-precision material feeds and indexing tables.
