2-112 Linking Parameters
Linking Parameters (Vector Control Option Only)
Most parameter values are entered directly by the user. However, certain
parameters can be “linked,” so the value of one parameter becomes the
value of another. For Example: the value of an analog input can be linked to
[Accel Time 2]. Rather than entering an acceleration time directly (via
HIM), the link allows the value to change by varying the analog signal. This
can provide additional flexibility for advanced applications.
Each link has 2 components:
• Source parameter – sender of information.
• Destination parameter – receiver of information.
Most
parameters can be a source of data for a link, except parameter values
that contain an integer representing an ENUM (text choice). These are not
allowed, since the integer is not actual data (it represents a value). Table 2.X
lists the parameters that can be destinations. All links must be established
between equal data types (parameter value formatted in floating point can
only source data to a destination parameter value that is also floating point).
Establishing A Link
Step Key(s) Example Displays
1. Select a valid destination parameter (see
Table 2.X
) to be linked. The parameter value
screen will appear.
2. Press Enter to edit the parameter. The cursor
will move to the value line.
3. Press ALT and then View (Sel). Next, press
the Up or Down Arrow to change “Present
Value” to “Define Link.” Press Enter.
4. Enter the Source Parameter Number and
press Enter.
The linked parameter can now be viewed two
different ways by repeating steps 1-4 and
selecting “Present Value” or “Define Link.” If
an attempt is made to edit the value of a
linked parameter, “Parameter is Linked!” will
be displayed, indicating that the value is
coming from a source parameter and can not
be edited.
5. To remove a link, repeat steps 1-5 and
change the source parameter number to
zero (0).
6. Press Esc to return to the group list.
