UIM241XX controller are miniature stepper motor controllers with RS232 control interface. The user device controls the UIM241XX through RS232 using ASCII coded instructions. UIM241XX controllers support open-loop and quadrature encoder (QE) closed-loop control. The UIM241XX architecture comprises communication, basic motion control, absolute position counter, QE interface and real-time event change notification modules. Embedded 64-bit calculation precision DSP controller guarantees the real-time control process. Furthermore, there are 3 optional advanced modules: Advanced Motion Control Module, QE Based Closed-loop Control Module and Sensor Control Module. With UIM241 Advanced Motion Control, selected NEMA 17/23 motors can ramp up to 4000 RPM in 0.25 seconds. UIM241 controllers can be mounted onto NEMA 17/23/34/42 series stepper motor through adapting flanges enclosure is made of die-cast aluminum to provide a rugged durable protection and improves the heat dissipation

Wiring of UIM241 is simple.
UIM241xx controllers use 3-wire RS232 interface to communicate with user devices. Terminal 3 should be connected to the RX of user device; Terminal 4 should be connected to the TX of user device; Terminal 5 should be connected to the GND of user device. An example is provided in figure 0-2. User can use an existing RS232 cable or a converted cable.
If the sensor inputs are used, make sure the signal are wired to the terminal 7 and/or terminal 8, and the signal ground are wired to the terminal 6. Furthermore, please be aware:
• User is responsible for the power supply for sensors,
• Voltage on terminal 7 and 8 must be kept between -0.3V and 5.3V
• If using an external encoder, channel A should be connected to S1; channel B to S2; GND to AG
