Axis Definitions Dialog

To access this dialog:
In the Project pane, expand the Axes folder and double-click Axis Definitions.
Or:
From the Axis Definitions page of the New Controller Wizard, click View/Change Axis Definitions.

Use this dialog to view or change existing axis definitions, or to add or remove axes.

View an Axis Definition

To view an axis definition, click the axis in the Axis Definition table. The hardware assigned to the selected axis is highlighted in the RMC image, and is color-coded for output, primary input, and secondary input.

To view detailed information on the selected axis definition, click Change.

The Axis column provides the following information:

	A control axis.
	A reference axes — commonly called a "half-axis".
	An invalid axis definition.
#	Indicates the number of the axis.
[]	The user-defined name of the axis.

Invalid axis definitions will be marked with a icon and red text. Invalid axis definitions can be downloaded to the RMC, but the axis may not be functional.

Change an Axis Definition

To change an axis definition, click the axis in the Axis Definition box, then click Change. When making major changes to the axis definition, it may be easier to first delete the axes, and then create new ones.

See the Axis Definitions: Change topic for details on changing an axis definition.

Rename an Axis

To rename an axis, select the axis and click Rename. Type a name and press Enter.

Add or Remove an Axis

To add an axis, click the axis in the Axis Definition box, then click New. See the New Axis Wizard topic for details on adding a new axis. To remove an axis, click the axis in the Axis Definition box, then click Remove.

The axis limits for the controller are listed at the top of the dialog.

Note: It is possible to add more analog inputs on the RMC75 than can be assigned to axes. However, it is still possible to view the voltage of the extra analog inputs using the Analog Input Registers. Inputs that are unassigned to axes can have no status bits, error bits, scaling, filtering, etc.

Change the Order of Axes

Note: Delta recommends defining the order of the axes at the beginning of the project. Once the project is underway, changing the axis order can break any programming you have already done.

To change the axis order, use the Move Up and Move Down buttons.

The axes will adhere to this order throughout the entire RMC. The Axis Tools and Command Tool will display the axes in this order, and the register addresses and tag names will be defined by this order.

Axis and Control Loop Limits (RMC200 Only)

As axes are added, the dialog lists the number of physical control axes, Feature Key control loops, total axes, and the maximum allowed values. For details on the limits, see the RMC200 Overview.

The Control Loop Utilization Advisory is an approximate graphical indication of how much of the loop time will be used for processing the axes. As described in the Loop Time topic, it is important that the actual loop processing time does not frequently or excessively exceed the selected loop time.

Buttons

Button	Description
New	Add a new axis.
Change	Change or view the definition of the selected axis.
Remove	Remove the selected axis.
Move Up	Move the selected axis up one position in the list.
Move Down	Move the selected axis down one position in the list.
Rename	Rename the selected axis.
OK	Close the dialog and apply the changes to the project. If you are online with the controller, the changes will also be applied to the controller. If you accessed this dialog from the New Controller Wizard, the changes will be applied to the wizard.
Cancel	Close the dialog without applying any changes.
