RS232 serial port Stepper Controller, UIM241 Series Stepper Motor Controller

Introduction of UIM241 series miniature intergrated stepper motor motion controller

UIM241XX controller are miniature stepper motor controllers with RS232 control interface. The user device controls the UIM241XX through RS232 using ASCII coded instructions. UIM241XX controllers support open-loop and quadrature encoder (QE) closed-loop control. The UIM241XX 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 UIM241 Advanced Motion Control, selected NEMA 17/23 motors can ramp up to 4000 RPM in 0.25 seconds. UIM241 controllers can be mounted onto NEMA 17/23/34/42 series stepper motor through adapting flanges enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation
