124 Using the Imaginary Axis
As shown previously, all the motion generating functions of physical
servo axes are available for the imaginary axis; it just cannot actually
move a motor. Each motion controller can have one imaginary axis
defined.
Configuring the Imaginary Axis
Like all other axes, the imaginary axis must be configured before it can be
used. As with any axis, configuring an imaginary axis is a two-step
process.
1. From the menu bar, select Configure. The Configure menu appears.
2. Select Control Options. The Configure Control Options dialog box
appears.
3. Select the Axes tab. (In Novice Mode, select Next to open the Axes
page.)
4. Select Imaginary. (Optionally, you can name the imaginary axis as
appropriate.) The default name, IMAGINARY, appears next to the
check box.
5. Select OK.
6. From the menu bar, select Configure. The Configure menu appears.
7. Select Axis Use. The Axis Use axis list appears.
8. Select IMAGINARY (or the name that you assigned to the imaginary
axis). The Configure Axis Use-IMAGINARY dialog box appears.
9. Make the appropriate settings. (See the Configuring Axis Use chapter
of this manual for field definition information on the setup menus
used to configure an axis.)
10. Select OK.
