IF_CartesianCalculations - GetCartesianVelocityFromCarrier (Method)

Overview

Type:	Method
Available as of:	V1.0.16.0

Task

Calculating the cartesian velocity (X, Y, Z) of a carrier with a given offset vector.

Description

With the method GetCartesianVelocityFromCarrier, you can calculate the velocity of the carrier in relation to the cartesian coordinate system of the track.

The position offset for the carrier in relation to the physical center point of the carrier (see Carrier Center Point) can be defined by the parameter i_stPositionOffset. For the calculation of the cartesian velocity of the carrier, this offset is taken into account.

Cartesian Coordinate System of the Carrier

Cartesian Coordinate System of the Track

For more information on the cartesian coordinate system of a Lexium™ MC multi carrier track, refer to the description of the Cartesian Coordinate System of the Track.

The value of the angle of the carrier is indicated by the parameter lrAngle in the interface IF_CarrierFeedbackSpace.

Inputs

Input	Data type	Description
i_ifCarrier	IF_Carrier	Accessing the carrier interface.
i_stPositionOffset	PDL.ST_Vector3D	Specifies the position offset in relation to the center point of the carrier.

Return value

Return value	Data type	Description
GetCartesianVelocityFromCarrier	PDL.ST_Vector3D	Returns the cartesian velocity (X, Y, Z) of carrier in relation to the cartesian coordinate system of the track.

Outputs

Output	Data type	Description
q_xError	BOOL	Indicates TRUE if an error has been detected. For details, refer to q_etResult and q_sResultMsg.
q_etResult	ET_Result	Provides diagnostic and status information as a numeric value. If q_xError = FALSE, q_etResult provides status information. If q_xError = TRUE, q_etResult provides diagnostic/error information.
q_sResultMsg	STRING [255]	Provides additional diagnostic and status information as a text message.
