UMI-7774
The UMI-7774/7772 simplifies field wiring by supplying a separate
feedback and control D-SUB connector for each axis. The UMI-7774/7772
connects the motion input and output to the motion controller through a
single interface cable. You can connect the UMI-7774/7772 digital inputs
and outputs to the controller with a separate interface cable to provide
access to up to eight digital inputs and eight digital outputs on the
controller. Also, the UMI-7774/7772 features a host bus monitor power
interlock that automatically disables the drive if the host computer is shut
down or the motion input/output interface cable is disconnected.
The UMI-7774/7772 includes the following features:
•
D-SUB connectivity, which provides easy and durable connectivity to
third-party devices
•
5 to 30 V limits and home switch/sensor compatibility
•
Global Stop inputs for global shutdown of all axes
