KL2541 | Stepper motor terminal 48 V DC, 5 A, with
incremental encoder
The KL2541 Bus Terminal is intended for stepper motors with medium performance range. The PWM output stages cover a wide range of voltages and
currents. Together with two inputs for limit switches, they are located in the Bus Terminal. The stepper motor terminal KL2541 can be adjusted to the
motor and the application by changing just a few parameters. 64-fold micro stepping ensures particularly quiet and precise motor operation. Together
with a stepper motor, the KL2541 represents an inexpensive small servo axis.
