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. Universal Motion Interfaces

National Instruments provides a wide selection of options for interfacing to motors. Y ou 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 steppe r 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. Cable BUY ONLINE!
