March 16, 2020 – Beckhoff Automation has released the EP7402 EtherCAT Box. This controller is a two-channel motor output stage for BLDC motors used in MDRs, regardless of the conveyor or roller motor vendor. The EP7402 offers conveyor control through zero-pressure accumulation (ZPA) logic in its firmware, programming in the TwinCAT 3 engineering environment and EtherCAT industrial Ethernet communication.

Designed for conveying tasks in intralogistics, packaging, food and beverage, assembly and many other industries, the EP7402 offers:

  • IP67 rated and compliant with new electrical standards being enforced in 2020
  • does not require a protective enclosure
  • measures 174 mm x 60 mm x 36.5 mm
  • mounts in standard C-channel or L-brackets directly on the conveyor frame
  • One Cable Automation (OCA) via two B23 ENP hybrid connectors
  • multiple M8 sockets to support two MDRs per device and digital I/O for peripheral sensors, vision systems or junctions to the entire range of EtherCAT Box modules

The EP7402 offers MDR conveyor systems the functionality and built-in diagnostics of EtherCAT. This OCA solution supplies both EtherCAT communication and 24 V DC for roller motors and peripheral I/O, and enables daisy chaining back to machine controllers. Optionally, 24 – 48 V DC versions are planned. The hybrid B23 cables can carry 28A to distribute power to up to 16 MDRs.

The MDR controller allows integrated functional safety in the system architecture via TwinSAFE technology from Beckhoff. As a result, conveying systems can incorporate standard e-stops, pull cords, light curtains and other safety devices into the EtherCAT P wiring solutions.
The EP7402 is fully integrated into TwinCAT 3 automation software, for programming and commissioning. ZPA for local control is fully autonomous and can be selected via parameters. Built-in motor protection features include voltage monitoring, thermal overload protection and overcurrent protection. Further, Beckhoff offers an intralogistics framework for additional features based off function blocks available in the TwinCAT platform for control of the entire system.
The TwinCAT IoT toolkit helps in installing EP7402 modules in data-intensive operations, such as digital transformation and Industrie 4.0 concepts. All MDR controllers can transmit diagnostic data back to TwinCAT Analytics for production dashboards and predictive maintenance in conveying systems.
