Introduction

The UMI-7774 and UMI-7772 (UMI-7774/72) are standalone connectivity accessories designed to be
used with National Instruments 73xx series motion controllers for up to four axes of simultaneous
or independent control. Ideally suited to industrial and laboratory applications, the UMI-7774/72
connects third-party stepper and servo drives (amplifiers) and/or feedback and digital I/O to National
Instruments motion controllers.
The UMI-7772 is a two-axis version of the UMI-7774. All illustrations, information, and specifications
in this manual apply to both devices.
Note For consistency, the remainder of this user manual refers only to drives. All references to
drives also apply to amplifiers.
You can use the UMI-7774/72 with a wide variety of drives designed for many types of motors or
actuators and power ranges. This flexibility allows you to use the UMI-7774/72 in systems where you
must use a third-party drive.
To work correctly with the UMI-7774/72, drives must have industry standard interfaces. For stepper
systems, the industry standard command signals are step and direction, or clockwise (CW) and
counter-clockwise (CCW), pulse inputs. For servo systems, the industry standard command signal is a
±10 V analog input.

Features

The UMI-7774/72 simplifies field wiring by supplying a separate feedback and control D-SUB
connector for each axis. The UMI-7774/72 connects the motion input and output to the motion
controller through a single interface cable. You can connect the UMI-7774/72 digital inputs and outputs
to the controller with a separate interface cable to provide access to up to eight digital inputs and
