UIM241

UIM241XX controllers are miniature stepping motor controllers with RS232 communication protocol. They can be mounted onto NEMA 17/23/34/43 series stepping motors seamlessly through corresponding flanges. The user controls the UIM241XX motion controller via RS232 commands. The instruction structure is simple, high fault tolerance with easy operation.

UIM241XX controllers support open-loop and quadrature encoder (QE) closed-loop control. With UIM241XX advanced motion control, selected NEMA 23 motors can ramp up to 4000 RPM in 0.25 seconds (Based on 1.8° motor). Driver enclosure is made of die-cast aluminum which provides a rugged, durable protection and improves the heat dissipation.
