UIM243XX
stepping motor controllers are series of microprocessor embedded, voltage control, miniature stepping motor controller. Its premier advantage is driving ability with a small size.
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 crashes 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 compensates for the impact caused by back-EMF when the motor is running at high speed. Drive enclosure is made of die-cast aluminum which provides a rugged, durable protection and improves the heat dissipation.
