UIM241XX controllers are miniature stepping motor controllers with RS232 communication protocol. They can be mounted onto NEMA 17/23/34/43 series stepping motor seamlessly through  corresponding flanges. The user controls the UIM241XX motion  controller via RS232 commands. The instruction structure is simple,  high fault tolerance. It can be operated by users who know nothing  about the stepping motor drive. 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) .The  enclosure is made of die-cast aluminum which provides a rugged,  durable protection and improves the heat dissipation.
