Precision Stepper Actuator - 100mm 250N

The traditional linear actuator uses a brush DC motor or brushless DC motor, even with a limit switch, it can not position to stop with full accuracy. By using a stepper motor, the linear actuator can be controlled by a standalone stepper controller. You can set when you want to open the window, how far you want it to open, and when to close the window making any home automation that much better. This Stepper actuator has a travel of 100mm and a torque rating of up to 250N.

DIP Pin Functions and Function Choices

The DM542 Stepper Motor Driver utilizes the SW1 to SW8 DIP pins to control the function of the stepper motors, the output current, as well as whether the current must be on standstill or not. The first three (SW1, SW2 and SW3) pins define the output current settings and should be adjusted according to the dynamic current necessary for your motor. The next pin (SW4) determines the current standstill setting, and is essentially a soft on/off switch, which sets the current to half when the motor is not in use. The final four pins (SW 5, SW6, SW7 and SW8) are for setting the micro step resolution, defining the amount of pulses per revolution.
