Run/stop, direction,high/low speed range and, enable/disable can be controlled simply by shorting the correspondingterminal 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 desiredspeed within 0.3 seconds, even when the speed control voltage is changing. This feature makes thesudden increase of the desired speed become possible.UIM24302 can provide 0 - 2A adjustable phase current. Their mixed-decay current control reducesthe back-EMF effect under high motor speed and improves the performance.UIM24302 can be mounted onto NEMA 17 / 23 series stepper motor seamlessly through adaptingflanges. The enclosure is made of die-cast aluminum which provides a rugged durable protection andimproves the heat dissipation.
