Description

The BECKHOFF ER7041-3002 is an EtherCAT Box module designed for precise positioning tasks in industrial automation environments. This compact IP65/66/67-rated module integrates a high-performance stepper motor output capable of driving 2-phase stepper motors, alongside integrated digital inputs and outputs and an encoder interface for closed-loop motion control applications.

Operating via the high-speed EtherCAT communication protocol, the ER7041-3002 supports distributed clocks for synchronized multi-axis operations and offers advanced dynamic current control. Housed in a robust industrial enclosure with M8 and M12 connection technology, this device connects directly to machine-level field environments without requiring a control cabinet.

Features

  • Integrated drive for 2-phase stepper motors (uni- and bipolar operation)
  • Combined digital input, digital output, and encoder interface functionality
  • Supports EtherCAT communication protocol with distributed clocks
  • Configurable step frequency up to 8000 full steps per second with 256-fold micro stepping
  • Dynamic current controller frequency for optimal motor performance
  • Comprehensive diagnostic LEDs for phase errors, loss of step, power, and enable status
  • Rugged IP65/66/67 machine-mount enclosure for harsh industrial conditions

Applications

  • Decentralized positioning and drive tasks in factory automation
  • High-speed pick-and-place systems and material handling equipment
  • Packaging machinery requiring synchronized multi-axis movement
  • Assembly lines utilizing cabinet-free machine topologies
