Position is the position to begin camming at. The default is –1, and the valid range is –1 or 0 through (master cycle – 1).

Enable enables/disables camming on the specified axis. Set Enable to TRUE to enable camming or FALSE to disable camming.

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

Axis ID is the axis to configure.

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 terminal of one VI to the Board ID Out 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 start or stop a camming operation on an axis. You can start or stop the camming operation immediately by setting Position to –1. To configure the camming operation to take place after the master device crosses a specific position inside the master cycle, set Position to a value between 0 and (master cycle – 1).

Refer to the Camming section of the NI-Motion Help for more information about camming operations.
