CAN protocol Stepper Controller, UIM242 Series Simple CAN Stepper Motor Controller

Introduction of UIM242 series NEMA 43 closed loop servo stepper motor driver

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.
