The 2800 compact operator interface is a programmable device designed for use with programmable logic controllers,
ASCII devices, digital drives and motion controllers. This manual describes the features and operation specific to the
Allen-Bradley ULTRA 3000 Digital Servo Drives.
The 2800 communicates with the ULTRA Drive
using the Host Command Protocol. A list of all the
supported commands can be found in the
configuration software help files.
When configured for RS-485, the 2800 can
communicate with multiple Drives..
The 2800 OIT is fully programmable using free
ScreenMaker 2000K Windows™ based off-line
software. The project designer can customize
each screen to fit the current application. Text
can be combined with up to eight data fields
associated with parameters located internal to the
drive. Numeric Data fields can be defined as read
only or read /write with high limits, low limits and
scaling.
The
Next
and
Prev
keys allow the operator to navigate through screens in an order predetermined by the project
designer. The numeric keypad allows the user to easily modify integer and floating point values. The four function keys
can be redefined to function differently on every screen. The function keys can be custom labeled with a slip in legend
tag, easily created using LegendMaker software. The 2800 utilizes Flash nonvolatile memory, the threat of losing the
customized screens (up to 500) due to a power loss, dead battery, etc., is nonexistent.
We recommend downloading and installing the free ScreenMaker 2000K software that includes a sample project. The
sample project demonstrates indexing control, velocity control, and Jog mode.
What are Screens & Fields?
The 2800 is customized for a particular application by creating screens. A screen is similar to a canned message and
may include variable information from the Drive. A group of text or a variable is referred to as a field. Each field has
an assigned size and position within a screen. Several field types are available and may be used in any combination
to produce a screen. Here is a brief description of the fields currently available.
Static Text
This field allows fixed character strings to be displayed within a screen. The field size and
position are user defined.
Scrolling Text
This field allows fixed character strings to scroll right to left within a defined window.
Horizontal
The window size and position are user defined.
Scrolling Text
This field allows lines of fixed character strings to scroll bottom to top within a defined
Vertical
window The window size and position are user defined.
