Product Description

Introduction of UIM241 series miniature intergrated stepper motor motion controller

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

Detailed Guideline

In order to serve you quicker and better, when you order UIM241 series miniature intergrated stepper motor motion controller, please provide the product model number in following format.

1) Peak current is decided by maximum supply voltage (Table 0-1).
2) Default control connector is T (screw terminal) if not selected.

Typical Application

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
