KL2541 - General connection examples

WARNING
Risk of injury through electric shock and damage to the device!

Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals.

Note
Connect the motor strands correctly!
  • one motor strand to clamping points A1 and A2,
  • the other motor strand to clamping points B1 and B2.
  • If you connect a motor phase to terminal points of different output stages (e.g. to A1 und B1), this can damage the output stages of the stepper motor terminal!

Connection types

The KL2541 Stepper Motor terminal has bipolar output stages and can control bipolar and unipolar motors.

Bipolar motors

Bipolar control (serial) of a bipolar motor

Bipolar control (parallel) of a bipolar motor

Documentation for stepper motors from Beckhoff

These two examples show the connection of the bipolar Beckhoff motors AS1010, AS1020, AS1030, AS1050 or AS1060.
Further information on stepper motors from Beckhoff can be found in the associated documentation available for download from our website at http://www.beckhoff.com/.

Unipolar motors

Bipolar control of an unipolar motor
