UIM242XX are miniature stepper motor controllers with CAN2.0B networking capability. Through the CAN-RS232 converter (UIM2501), user device can command multiple UIM242 controllers through RS232 using ASCII coded instructions

UIM242XX controllers support open-loop and quadrature encoder (QE) closed-loop control. The UIM242XX architecture comprises communication, basic motion control, absolute position counter , QE interface and real-time event change notification modules. Embedded 64-bit calculation precision DSP controller guarantees the real-time control process. Furthermore, there are 3 optional advanced modules: Advanced Motion Control Module, QE Based Closed-loop Control Module and Sensor Control Module. With UIM242XX Advanced Motion Control. selected NEMA 17/23 motors can ramp up to 4000 RPM in 0.25 seconds. UIM242XX controllers can be mounted onto NEMA17/23/34/42 series stepper motor through adapting flanges. Enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation
