UIM241XX controllers are miniature stepping motor controllers
with RS232 communication protocol. They can be mounted onto
NEMA 17/23/34/43 series stepping motor seamlessly through
corresponding flanges. The user controls the UIM241XX motion
controller via RS232 commands. The instruction structure is simple,
high fault tolerance. It can be operated by users who know nothing
about the stepping motor drive. UIM241XX controllers support
open-loop and quadrature encoder (QE) closed-loop control. With
UIM241XX advanced motion control, selected NEMA 23 motors can
ramp up to 4000 RPM in 0.25 seconds (Based on 1.8° motor) .The
enclosure is made of die-cast aluminum which provides a rugged,
durable protection and improves the heat dissipation.
