UMI-7764

National Instruments UMI-7764 / UMI-7772 / UMI-7774 Universal Motion Interfaces
Features

• 2 and 4 Axis Univeral Motion
• Per-Axis Motion Signal
• Screw Terminal Connectors
• Up to 20 MHz Quadrature Encoder Rates
• Built-in Inhibit Logic

These National Instruments UMI interfaces 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.

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.
