General Specification

The 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 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 AKT-SM-L50-000 represents an inexpensive small servo axis.
