High-Performance Stepper Motor Control for EtherCAT

The KL2541 two-channel stepper motor terminal from Beckhoff is a compact, powerful solution for integrating stepper motor control directly into your EtherCAT I/O system. It generates the pulse and direction signals required to control two independent stepper motor drives with high precision and speed, offloading the central PLC for efficient, distributed motion control.

Key Features & Benefits

• Dual-Channel Control: Independently control two stepper motors from a single, compact Bus Terminal module.

• High-Speed Operation: Achieve output frequencies of up to 1 MHz per channel, enabling high-speed positioning for dynamic applications.

• Integrated Motion Control: The module handles trajectory generation locally, freeing the main controller from pulse calculation tasks. Supports relative and absolute positioning, homing, and jogging modes.

• Hardware-Based Precision: Features integrated hardware position compare and latch inputs for ultra-fast and highly accurate reaction to external sensor signals.

• Seamless EtherCAT Integration: Fully integrated into the Beckhoff automation environment. Simple configuration and programming via TwinCAT engineering software.

• Reduced Wiring: Connection to motor drives via a standard 25-pin D-Sub connector, simplifying cabling.
