Introduction

The UMI-7764 is a standalone connectivity accessory designed to be used with National Instruments
7330, NI 7340, and NI 7350 series motion controllers for up to four axes of simultaneous or independent
control. Ideally suited to industrial and laboratory applications, the UMI-7764 connects third-party
stepper and servo drives (amplifiers) and/or feedback and digital I/O to National Instruments motion
controllers.
Note
For consistency, the remainder of this document refers only to drives. All references to drives
also apply to amplifiers.
To work correctly with the UMI-7764, drives must have industry standard interfaces. For stepper
systems, the industry standard interface includes step and direction, or clockwise (CW) and
counter-clockwise (CCW), pulse inputs. For servo systems, the industry standard interface includes a
±10 V analog input.

  • Page 1: Table Of Contents

    The UMI-7764 is a standalone connectivity accessory designed to be used with National Instruments 7330, NI 7340, and NI 7350 series motion controllers for up to four axes of simultaneous or independent control. Ideally suited to industrial and laboratory applications, the UMI-7764 connects third-party stepper and servo drives (amplifiers) and/or feedback and digital I/O to National Instruments motion controllers.

  • Page 2: Features

    UMI features a host bus monitor power interlock that automatically disables the drive if the host computer is shut down or the interface cable is disconnected. The UMI-7764 is encased in a metal box with a hinged lid and comes with attached rubber feet for desktop use.

  • Page 5: Power Input Terminal Block

    Power Input Terminal Block The UMI-7764 has a 2-position terminal block for wiring power to the unit. Refer to Figure 2 to locate the power input terminal block on your UMI-7764 accessory. Figure 3 shows the 2-position terminal block pinout.
  • Page 6 Each UMI-7764 axis motion I/O terminal block has five terminals for drive connections. Refer to Figures 2 and 4 to locate the drive terminals on your UMI-7764 accessory. Figure 5 shows the UMI-7764 drive terminal block pin assignment for the servo or stepper axes.
  • Page 7 You can configure the axis Inhibit Out signal as active-low or active-high using switch S1. Refer to Figure 2 to locate switch S1 on your UMI-7764. Setting S1 to the bottom configures the signal as active-low; setting S1 to the top configures the signal as active-high.
  • Page 8 1 Connect to Digital Ground Figure 8. Single-Ended Encoder Pin Assignments The UMI-7764 accessory allows for differential inputs for Phase A, Phase B, and Index signals. You can easily accommodate encoders with phase relationships different from Figure 9 by swapping the signals as required by the specific application.
  • Page 9 Each UMI-7764 axis motion I/O terminal block has five terminals for Forward Limit, Reverse Limit, Home switch, and Inhibit Input connections. Refer to Figures 2 and 4 to locate the terminals on your UMI-7764 accessory. Refer to Figure 10 for the UMI-7764 limit switch and Inhibit Input terminal block pinout.
  • Page 10 Breakpoint Output/Trigger Input Terminal Block For breakpoint output and trigger input wiring, the UMI-7764 has a 10-position terminal block. This terminal block provides access to the four breakpoint outputs and the four trigger inputs. Refer to Figure 2 to locate the breakpoint output/trigger input terminal block on your UMI-7764 accessory. Refer to Figure 12 for the breakpoint output and trigger input pinout.
