GENERAL DESCRIPTION
UIM24102 / UIM24104 / UIM24108 are miniature stepper motor controllers with RS232
interface. UIM241 controllers can be mounted onto NEMA17/23/34/42 series stepper
motor through adapting flanges. 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 can realize open-loop and encoder-based closed-loop control. UIM241's
architecture includes communication system, basic motion control system, absolute
position counter, quadrature encoder interface and real-time event-based change
notification system. Furthermore, there are three optional modules can be installed per
customer
request:
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.
Enclosure is made of die-cast aluminum to provide a rugged durable protection and
improves the heat dissipation.
