Introduction
The UMI products are connectivity accessories you can use with your
motion control boards for up to four or six axes of simultaneous or
independent control. Ideally suited to industrial and laboratory
applications, UMI accessories connect power supplies, servo amplifiers
or stepper drivers, motors, encoders, and limit switches to National
Instruments plug-in motion control boards.
A UMI accessory simplifies field wiring with separate encoder, limit
switch, and amplifier/driver terminal blocks per axis. All terminal blocks
are industry standard and do not require any special tools for wire
installation. The UMI accessory connects to the motion controller via a
single interface cable. The UMI accessory has a host bus monitor power
interlock that automatically disables the amplifiers if the host computer is
shut down or the interface cable is disconnected.
The UMI-4A and UMI-Flex4 come with an integrated DIN-rail mounting
base. The UMI-Flex6 is encased in metal and comes with attached rubber
feet for desktop use; a DIN-rail mounting kit is available separately. The
UMI-7764 is encased in a metal box with a hinged lid and comes with
attached rubber feet for desktop use.
