UIM24302 stepper motor controller is a microprocessor embedded, voltage control, miniature stepper
With the UIM24302, the motor speed can be controlled by an analog voltage in three optional ways:
1) the on-board trimmer, 2) an external potentiometer or, 3) an external voltage. Run/stop, direction,
high/low speed range and, enable/disable can be controlled simply by shorting the corresponding
terminal to the ground. UIM24302 controllers can run the motor without user control device.
The microprocessor of the UIM24302A/B is capable to ramp up the current speed to the desired
speed within 0.3 seconds, even when the speed control voltage is changing. This feature makes the
sudden increase of the desired speed become possible.
UIM24302 can provide 0 - 2A adjustable phase current. Their mixed-decay current control reduces
the back-EMF effect under high motor speed and improves the performance.
UIM24302 can be mounted onto NEMA 17 / 23 series stepper motor seamlessly through adapting
flanges. The enclosure is made of die-cast aluminum which provides a rugged durable protection and
improves the heat dissipation.
