STEPMOTOR with integrated driver SMD‑2.8mini

SMD­2.8mini is a step motor driver, which is designed to be buit-in into stepper motors. At the moment these drivers are offered together with stepper motors as whole assembled units. No need of connecting, adjusting or any other preparation - the system is a ready to work complete step motor drive.

As SMD­2.8mini drivers has quite little dimensions, these complete drives save space in a final product. As these drives are supplied as whole units, no need of connection and adjusting driver and step motor and save personnel's time.

Control mode is standard Pulse/Dir mode – step motor driver receives voltage pulses as Step signal and voltage level as Direction signal. Motion displacement depends on pulses number, motion speed is proportional to pulses frequency. The direction depends on voltage level on DIR input.
