General Description
UIM24102 / UIM24104 / UIM24108 are miniature stepper motor controllers with RS232 interface. User
device can command these controllers through RS232 protocol using ASCII coded instructions.
Instructions are simple, intuitive and fault-tolerating. User is not required to have advanced knowledge
on stepper motor driving.
UIM241’s architecture includes communication system, basic motion control system, Quadrature
encoder interface and real-time event-based change notification system. Furthermore, there are three
optional modules can be installed per customer request: Advanced Motion Control Module (linear/nonlinear acceleration/deceleration, S-curve PT/PVT displacement control), Encoder-based Closed-loop
Control Module and Sensor Input Control Module.
Embedded 64-bit calculating precision DSP controller guarantees the real-time processing of the motion
control and change notifications. Entire control process is finished within 1 millisecond.
UIM241controllers can be mounted onto NEMA17/23/34/42 series stepper motor through adapting
flanges. Total thickness of the controller is less than 16.5 mm. Enclosure is made of die-cast aluminum
to provide a rugged durable protection and improves the heat dissipation.
