Product Description

Description

The BECKHOFF KL2541 is a single-channel Bus Terminal designed for the direct connection of stepper motors up to 5.0 A. Operating within the modular K-bus system, this compact drive terminal integrates a power stage for a stepper motor alongside a feedback interface for a 24 V DC single-ended incremental encoder. This integrated feedback loop enables precise, closed-loop positioning control in a compact physical form factor.

By supporting microstepping up to 64-fold, the BECKHOFF KL2541 ensures smooth motor operation, minimized resonance, and highly precise positioning. The terminal manages internal current control and features built-in travel distance control, offloading computational requirements from the central controller and allowing direct execution of positioning tasks.

Features

  • Direct motor connection interface for one stepper motor.
  • Integrated incremental encoder input (5 to 24 V DC) for closed-loop position feedback.
  • Support for full step, half step, and up to 64-fold microstepping.
  • Internal travel distance control function.
  • Electrical isolation of 500 V between the K-bus and the signal/power voltage.
  • Diagnostic LEDs indicating phase errors, step loss/stagnation, power status, and enable state.

Applications

  • Closed-loop and open-loop stepper motor positioning control.
  • Compact drive axes in assembly, sorting, and packaging systems.
  • Feed adjustments and precise positioning in material handling equipment.
  • Actuators and auxiliary movement axes in general machine building.

Installation Guidelines

  1. Ensure the system controller and K-bus rack power supply are completely de-energized before mounting.
  2. Mount the terminal onto a standard 35 mm DIN rail (EN 60715) by sliding it into place until the locking mechanism clicks securely.
  3. Ensure the bus terminal contacts line up correctly with adjacent terminals on the K-bus rail.
  4. Connect the external power supply (8 to 48 V DC) for the motor power according to standard wiring schematics.
  5. Connect the stepper motor phases and the incremental encoder signal lines. Secure all connections using the spring-loaded wire terminals.
  6. Re-energize the K-bus station and verify the status of the diagnostic LEDs on the front panel of the terminal.
