This manual provides information about the National Instruments
Universal Motion Interface (UMI)-7774/7772 functionality and includes
instructions for getting started, specifications, connection requirements,
and safety information.
The UMI-7774 and UMI-7772 (UMI-7774/7772) 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-7774/7772 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.
You can use the UMI-7774/7772 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-7774/7772 in systems where you must use a third-party
drive.
To work correctly with the UMI-7774/7772, 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.
