Owning Palette: Reference Data Processing VIs

Installed With: Sound and Vibration Measurement Suite

Computes the vector references of the specified orders from the slow-roll vibration signals. Use the vector references to compensate shaft bow or runout errors. The data type you wire to the scaled signal [EU] input determines the polymorphic instance to use.

Use the pull-down menu to select an instance of this VI.

OAT Get Vector Reference (1 Channel)

	reset? specifies the initialization of the internal states. The first time this VI runs, or when reset? is TRUE, the internal states initialize to zero. If reset? is FALSE, this VI sets the internal states to the final states from the previous call to the VI. The default is FALSE.
	reference output mode specifies the output mode of vector references. 0 averaged samples—(Default) Specifies that this VI returns the averaged vector of the orders you specify. 1 initial samples—Specifies that this VI returns the first vector of the orders you specify. 2 final samples—Specifies that this VI returns the last vector of the orders you specify.
	scaled signal [EU] specifies the scaled signal expressed in the selected engineering units. To obtain a properly scaled signal, you can use the SVL Scale Voltage to EU VI or define a virtual channel in Measurement & Automation Explorer (MAX).
	speed profile specifies the arrival time and the rotational speed of each tachometer pulse. time [s] specifies the arrival time, in seconds, of each tachometer pulse. speed [RPM] specifies the rotational speed, in revolutions per minute, of each tachometer pulse.
	pulse/revolution specifies the number of pulses the tachometer generates during each revolution. The default is 1.
	orders to compensate specifies the order components to compensate. The default value is 1.00.
	error in describes error conditions that occur before this node runs. The default is no error. If an error occurred before this node runs, the node passes the error in value to error out. This node runs normally only if no error occurred before this node runs. If an error occurs while this node runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this node ran or FALSE (checkmark) to indicate a warning or that no error occurred before this node ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning. The default is an empty string.
	bandwidth [order] specifies an order span centered at the order that you specify in orders to compensate. Specify a bandwidth [order] value between 0 and 1. If bandwidth [order] is less than 0 or greater than 1, this VI sets bandwidth [order] to 1. The default is 1.
	vector references returns slow-roll vector references of the orders you specify.
	error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, it describes the error status that this node produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning.
