Data is a cluster of variables that contains the values for the selected Attribute.

	Integer is 32-bit integer data.
	Double is 64-bit floating point data.
	Boolean is Boolean data.

Attribute is the attribute you want to load:

Enable enables the currently selected axis. Set the Boolean element of the Data cluster to TRUE to enable the axis, and to FALSE to disable the axis.

Board ID is a unique number assigned by Measurement & Automation Explorer used to send and receive commands and data to or from a specific NI motion controller.

Axis ID is the axis you are controlling.

error in (no error) describes error conditions that occur before this VI runs. The default input of this cluster is no error. If an error already occurred, this VI returns the value of error in in error out. The VI runs normally only if no incoming error exists. Otherwise, the VI passes the error in value to error out. The error in cluster contains the following parameters:

	status is TRUE if an error occurred before this VI was called, or FALSE if not. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code.
	code is a number identifying an error or warning. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code. Use the error handler VIs to look up the meaning of this code and display the corresponding error message.
	source is a string that indicates the origin of the error, if any. Typically, source is the name of the VI in which the error occurred.

Board ID Out is provided for flow control. You can string together NI-Motion VIs by wiring the Board ID Out terminal of one VI to the Board ID terminal of the next VI.

Axis ID Out is provided for flow control. You can string together NI-Motion VIs by wiring the Axis ID Out terminal of one VI to the Axis ID terminal of the next VI.

error out contains error information. If error in indicates an error, error out contains the same error information. Otherwise, it describes the error status that this VI produces.

	status is TRUE if an error occurred, or FALSE if not. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code.
	code is a number identifying an error or warning. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code. Use the error handler VIs to look up the meaning of this code and display the corresponding error message.
	source is a string that indicates the origin of the error, if any. Typically, source is the name of the VI in which the error occurred.

Using This VI

Use this VI to load the data on a per axis basis for the Axis Configuration object on the motion controller.

Remarks

This section includes information about how the behavior of this VI differs among the controllers that support it.

NI 73xx Controller Considerations

The following list includes considerations you must make when you are using this VI with a 73xx controller:

Because the number of axes enabled depends on the control loop rate, use the Enable Axes VI to enable/disable an axis for 73xx controllers.
