Stepper drive modules are available in 24V, 1.5A and 50V DC, 5A for small and medium stepper motors. Both support velocity and position based modes. AKT-SM-L50-000 The AKT-SM-L50-000 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. AKT-SM-L15-000 Bus Terminal The AKT-SM-L15-000 Bus Terminal is intended for the direct connection of different small stepper motors. The slimline PWM output stages for two motor coils are located in the Bus Terminal together with two inputs for limit switches. The 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. In many applications, integrated zero-speed monitoring makes an encoder system or limit switch unnecessary.
