Description

The BECKHOFF EPP5101-0002 is a decentralized EtherCAT P Box module designed for the direct connection of incremental encoders. Operating as a 1-channel interface, this module is engineered to process differential RS422 or single-ended TTL signals. It enables highly accurate, high-speed displacement and positioning measurements directly in the field, eliminating the need for protective control cabinets.

By leveraging EtherCAT P technology, the BECKHOFF EPP5101-0002 combines high-speed communication and power supply (both system and sensor supply Us and peripheral voltage for actuators Up) in a single, standard P-coded M8 connection. The unit features built-in support for Distributed Clocks (DC), ensuring precise synchronization with other EtherCAT system components.

Features

  • 1-channel incremental encoder interface.
  • Compatible with differential RS422 and single-ended TTL signals.
  • Integrated 5 V DC encoder power supply rated at 150 mA.
  • Supports high-speed 32-bit or 16-bit binary counter operations.
  • Zero-pulse latch capability for precise position indexing.
  • Distributed Clocks (DC) support for microsecond-level synchronization.
  • Dual P-coded M8 EtherCAT P connectors for easy daisy-chaining.

Applications

  • Decentralized high-speed counting and position feedback systems.
  • Industrial motion control, positioning loops, and speed measurement.
  • Assembly lines, packaging machines, and conveyor control.
  • Harsh environment installations requiring direct machine mounting without control enclosures.

Installation Guidelines

  1. Ensure the system power supply is completely de-energized before beginning installation.
  2. Securely mount the EtherCAT P Box module to a flat, vibration-resistant machine surface using the integrated mounting holes.
  3. Connect the EtherCAT P incoming and outgoing lines using shielded, P-coded M8 cables. Ensure connectors are threaded and tightened properly to protect the internal seals.
  4. Wire the incremental encoder to the 8-pin M12 connection socket, verifying correct signal and power pinout configurations prior to connection.
  5. Verify that all unused M8 and M12 sockets are covered with appropriate protective caps to maintain the IP65/IP66/IP67 ingress protection rating.
  6. Enable the supply voltage and configure the module within your TwinCAT development environment.
