These products provide a comprehensive wiring and connection point for motion control and feedback signals. A single cable from the motion controller to the UMI carries input and output signals for all axes. By dividing these signals into per-axis and function-specific connections, the UMI interface simplifies integration of third-party drivers, amplifiers, encoders, limits, and I/O with NI controllers. Each UMI works with up to 20 MHz quadrature encoder rates. Each UMI incorporates a host PC power monitor that inhibits the motion driver if the host PC loses power during motion control. The UMI monitors the +5 VDC from the PC and activates the inhibit signals if the voltage falls out of tolerance. Features Enhanced motion-specific features set the UMI apart from simple connector-only screw terminal blocks. Compatibility with both TTL and differential encoders, input filtering, host-PC power monitoring, onboard inhibit functionality, and compact size make the UMI the ideal motion interface solution. The result is simplified wiring to third-party amplifier/driver and motor components. Refer to ni.com/motion for integrated amplifier, power supply, and connectivity solutions. Some signals have compatibility defined as signal pass-through, which means the UMI may have passive filtering on these signals but voltage range or current handling capabilities are not affected. Consult your motion controller specifications to determine the allowable voltage range and logic level compatibility of the signal.

Typical Motion System Components Universal Motion Interfaces Connecting to Motor Drives When interfacing to a third-party power drive and motor, it is important to consider the amount of current to drive the motor and the connectivity to a motor drive. National Instruments provides a wide selection of options for interfacing to motors. You can interface to 2-phase stepper motors with 4 A peak current using National Instruments power drives. In addition, you can interface to 5-phase stepper motors and other stepper motors outside the range of NI MID Series drives using National Instruments UMI interfaces. For DC-brush servo motors that need up to 10 A peak current, you can use National Instruments power drives and controllers. For DC brushless, AC, and other types of servo motors outside the range of NI MID Series drives, an NI UMI interface simplifies connections to the motor and controller.
