Description

UIM24104 and UIM24108 are miniature stepper motor controllers with RS232 interface. User device can command these controllers through RS232 using ASCII coded instructions. Instructions are simple, intuitive and fault-tolerating. User is not required to have advance knowledge on stepper motor driving.

UIM241 controller’s architecture comprises communication system, basic motion control system, absolute position counter, and real-time event-based change notification system. Embedded 64-

bit calculation precision DSP controller guarantees the real-time processing of the motion control

and change notifications. There are 2 optional advanced modules for selection: Advanced Motion Control Module and Input Control Module. With UIM241’s Advanced Motion Control, selected NEMA 17/23 motors can ramp up to 6600 RPM in 0.5 seconds and 4000 RPM in 0.25 seconds (online video

available for downloading).

UIM241 controllers can be mounted onto NEMA17/23/34/42 series stepper motor through adapting flanges. Controller thickness is less than 14 mm. Enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation.
