1.UIM243 Series Voltage Control Stepper Controller n Driver
UIM243XX stepper motor controllers are series of microprocessor embedded, voltage control, miniature stepper motor controller. UIM24301 is a sub-miniature controller, whose land pattern is standard DIP18(0.6”width) and can be mounted onto user PCB directly. With the UIM243XX controller, motor speed can be adjusted through an analog voltage. There are 3 ways to generate the said analog voltage:1) use the on-board trimmer,2) use user potentiometer or 3) direct input a voltage. Run/stop, direction, high/low speed range and, enable/disable can be controlled simply by shorting the corresponding terminal to the ground. UIM243XX controllers can run the motor without user device. UIM24302 provides 0-2A adjustable phase current, and UIM24301 provides 0-1A adjustable phase current.UIM24302 can be mounted onto NEMA 17/23 series stepper motor seamlessly through adapting flanges. The enclosure is made of die-cast aluminum which provided a rugged durable protection and improves the heat dissipation.
