Section 1: Introduction Page 1
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.

Numeric Data Field
This field will display numeric values associated with drive parameters. The parameter from which data will be retrieved
is specified when the field is created. Signed and unsigned integer values plus floating point formats are supported.
Modification to the value may be enabled or disabled. Individual data value limits are also set for each Numeric Data
field created. If enabled, values are entered by first moving the focus to this field by pressing the Select key, a new
value is then keyed in and the Enter key pressed.
Note:
If a Scale value other than one is assigned with an integer type variable such as Index Distance, please be aware
of the following:
If a decimal value is specified as shown here (Dbl.Decimal.3), then the entry and display of the variable is treated
as a floating point value, however, the limit values remain in the native integer format and in this example would
indicate maximum and minimum counts.
Example: Assume 8000 counts (1 revolution) equals 0.01 inches of travel.
The desired range of travel is from, -1.25 inches to six inches.
Scale: 0.01 Divided by 8,000 equals 0.00000125 (or 1.25e-6)
Maximum Entry Value: 6.00 / 0.00000125 = 4,800,000
Minimum Entry Value: -1.25 / 0.00000125 = -1,000,000
The decimal point in the Max and Min Entry Values is a place holder only and is not numerically significant to the
entered limit value. If it is not placed correctly an integrity check error may occur.

Section 1: Introduction Page 3
The Negate check box will force a positive entered value to be converted to a negative value before it is written to the
Ultra Drive. Likewise, when a negative value is read from the Ultra Drive it will be converted to a positive number
before it is displayed. The function would be used only when the variable must always be negative. For example, if
the motor must always turn in the negative direction, the operator would not have to remember to press the negative
key when entering a speed, distance, or position.
Scaling Example: Since the drive returns the current motor velocity as a number of counts per second we can use
a scale value to convert the displayed value to revolutions per minute (RPM).
Scale Value = 1 / ( Counts per Revolution / 60 )
Scale Value = 1 / ( 8,000 / 60 ) Assume encoder producing 8,000 counts per revolution.
Scale Value = 1 / 133.33333
Scale Value = 0.0075 or 7.5e-3 This is the value into the Scale box.
If the 2800 has received a motor velocity value of 200,000.
RPM = Count Value Received x Scale Value
RPM = 200,000 x 0.0075
RPM = 1500 This is the value displayed by the 2800
If the operator enters 750, the 2800 will write the value 100,000 to the Drive..
Raw Value = Entered value / Scale Value
Raw Value = 750 / 0.0075
Raw Value = 100,000 This is the value written to the Ultra Drive.
Velocity Scaling: convert from Counts / Second to Revolutions / Minute.
Scale value = 60 divided by encoder pulses per revolution.
Accel/Decel Scaling: convert from Counts / Second / Second to Revolutions / Second / Second
Scale value = one divided by encoder pulses per revolution.

Recipe Field
This field appears as fixed text within a screen. The field can be used in a two different ways.
As an Increment/Decrement Function:
When the field is created a parameter, Increment/Decrement value, and limit value are specified in addition to the field
text. If the Usage is set to Increase value then moving the focus, via the Select key, to this field and pressing the Enter
key will cause the increment value to be added to the data value currently read from the Ultra Drive. If the addition of
the two values exceeds the limit value then a warning message is displayed and the variable in the Ultra Drive is left
unchanged. Focus in not automatically removed from the field so that the additional increments may be executed.
Focus is removed by pressing either the Cancel or Select key. If the Usage is set to Decrease value then operation
is identical except that the decrement value is subtracted from the Ultra Drive data value.
As a Recipe List:
Up to twenty Ultra 3000 parameters can be assigned within the recipe field. Moving the focus, via the Select key, to
this field and pressing the Enter key will cause the data values to be written to the assigned addresses within the Ultra
Drive.
PM2800U3K Revision 4

Section 1: Introduction Page 5
The Execute drop down box allows the Recipe field to function in three different ways.
On Select is the default choice and causes the Recipe field to function like all other data
access fields. That is, The Select key is used to set focus to the field then the Enter key is
used to execute the specific field function When Increment or Decrement is used this is the
only valid execute method allowed.
When a screen is first opened the various field types that make up the screen go through an
initialization procedure. This procedure places associated text on the display and opens
connections to the communication driver if the field type is a data access field such as a
Recipe field.
If the Execute method selected for a Recipe field is an As LinkID then the initialization procedure and operation of the
field are changed. A connection to the communication driver is still made but the field text is not shown on the 2800
display and the field is not selectable using the Select key. A pointer to the Recipe is stored in the internal memory
of the 2800. To cause the Recipe items to be downloaded to the Ultra this Recipe fields Link ID must be included within
another Recipe. This is done using the Recipe Link ID parameter found within the Data Reference list. When the
Recipe Link ID parameter is encountered within an executing Recipe field the download process will continue using
the parameters included in the linked Recipe. The Recipe Link ID parameter should be the last parameter within a
recipe list and the assigned value must be that of a valid linked recipe. A linked Recipe field can include a Recipe Link
ID within its parameter list allowing multiple linked recipes to be executed.
If the Execute method selected for a Recipe field is On Open then a connection to the communication driver is made
but the field text is not shown on the 2800 display and the field is not selectable using the Select key. The field will
automatically be executed, downloading the parameter list to the Ultra drive.
Within ScreenMaker 2000K the text associated with a Recipe field is always shown, must be at least one character,
and may not be covered by another data access field.

Bit Status Field
When creating this field a mask value and data value for a drive parameter are specified. Two character strings are
also typed in, one for the true state of the bits and one for the false state of the bit. One of the two character strings
will then be displayed depending on the status of the specified data value versus the mask value. If enabled this field
will also function as a bit modify. Moving the focus, via the Select key, to the field and pressing the Enter key will
cause the bits to be complimented by the 2800.
How the Bit Status determines which string to display:
Example 1:
Drive Value 0000 0000 0000 0001
AND with Mask Value 0000 0000 0000 0001
Results 0000 0000 0000 0001
The result is equal to the Data Value, therefore, the True Text [STOP] would be displayed on the 2800.
Example 2::
Drive Value 0000 0000 0000 0000
AND with Mask Value 0000 0000 0000 0001
Results 0000 0000 0000 0000
The result and Data Value are not equal, therefore, the False Text [START] would be displayed on the 2800.
PM2800U3K Revision 4

Section 1: Introduction Page 7
How the Bit Status field functions when Entry Allowed is selected:
Assume the results of example one, the field is currently displaying [STOP]. Further assume you use the Select key
on the 2800 to assign focus to this field then press the Enter key.
Drive Value 0000 0000 0000 0001
AND with compliment of Mask Value 1111 1111 1111 1110 Formula 1
write this value to the Drive 0000 0000 0000 0000
2800 reads Drive Value back 0000 0000 0000 0000
2800 ANDs it with Mask Value 0000 0000 0000 0001
Results 0000 0000 0000 0000
Result does not match Data Value so the field text will change to [START].
Lets try the opposite case. Assume the results of example two, the field is currently displaying [START]. You use
the Select key on the 2800 to assign focus to this field then press the Enter key.
Assumed PLC Value 0000 0000 0000 0000
AND with compliment of Mask Value 1111 1111 1111 1110 Formula 2
Results 0000 0000 0000 0000
OR with Data Value 0000 0000 0000 0001
write this value to the PLC 0000 0000 0000 0001
2800 reads PLC Value back 0000 0000 0000 0001
2800 ANDs it with Mask Value 0000 0000 0000 0001
Results 0000 0000 0000 0001
Result does match Data Value so the field text will change to [STOP].

Section 1: Introduction Page 8
Multi-State Text Field
This field monitors an assigned parameter and displays text associated with a specified value. Up to 25 Value/Text
Strings can be specified. Entry is allowed with this field. After selecting this field the Next and Prev keys can be
used to scroll through the text strings, When the desired text string is displayed, the Enter key can be pressed
which will cause the value associated with the text string to be written to the Drive.
