UIM242XX are miniature stepping motor controllers with CAN  networking capability. They can be mounted onto NEMA 17/ 23/  34/43 series stepping motor seamlessly through corresponding  flanges. The thickness is less than 16.5mm. CAN bus communication has many advantages like High-speed, long-distance and anti-jamming. With CAN bus gateway, Users can control UIM242XX  controller with long-distance and high-speed by turning RS232  instructions into CAN protocol instructions.Users can control up to  100 sets UIM242XX controllers at the same time only by one  CAN bus gateway. UIM242XX controllers support open-loop and  quadrature encoder (QE) closed-loop control. With UIM242XX  advanced motion control, motors can ramp up to 4000 RPM  in 0.25 seconds (Based on ∠1.8° motor). Embedded 64-bit calculation precision DSP controller guarantees the real time control  process, motion control and event change notification can be  completed in 1-2 milliseconds. The enclosure is made of die-cast  aluminum which provides a rugged, durable protection and improves the heat dissipation.
