Load Run/Stop Threshold

Sets the velocity Run/Stop Threshold, which affects the run/stop status returned by Read Trajectory Status.

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.

Run/Stop Threshold is the Run/Stop threshold velocity in counts/sample period for servo axes or steps/sample period for open-loop and closed-loop stepper axes. The range for this parameter is 1 (default) to 32,767 counts or steps/sample period. This parameter sets the number of counts/steps an axis must move to be considered running.

Axis is the axis to configure.

Inp Vect indicates the source of the data for this VI. Available input vectors include immediate (0xFF), variable (0x01 through 0x78), or indirect variable (0x81 through 0xF8). Refer to Input and Return Vectors for more detailed information.

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.

Bd ID Out

Resource Output is the Axis, Vector Space, ADC, or Encoder you wired into the VI. Use Resource Output to pass the resource to another VI and/or to display information about the device.

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

This VI sets the velocity threshold above which an axis is considered running. The Run/Stop Threshold parameter has time units of update sample periods and is affected by the update rate set in the Enable Axes VI.

If the velocity of an axis is above the step/count per sample period specified in this VI, the run/stop status from Read Trajectory Status returns TRUE. If it is below the threshold, the run/stop status returns FALSE.
