UIM243XX
stepping motor controllers are series of microprocessor embedded, voltage control, miniature stepping motor controller.Its biggest feature is the small size and the driving ability. They can be mounted onto NEMA 17 / 23 series stepping motor seamlessly through corresponding flanges. With UIM243XXA/B advanced acceleration function by embedded microprocessors, motors can ramp up to 1900 RPM in 0.3 seconds (Based on 1.8° motor) , it can avoid crash caused by the fast start up frequency. Users can set the speed by fine-tune the resistance (UIM243XXA) or through an external adjustable potentiometer (UIM243XXB) or use 0-5V voltage. Once powered on, it can run without host computer’s control. Its high-speed current compensation can compensate for the impact caused by back-EMF when the motor is running at high speed. The enclosure is made of die-cast aluminum which provides a rugged, durable protection and improves the heat dissipation.
