Name	Type	Description
Valid	BOOL	This output indicates that other output values are valid for this function block.
Busy	BOOL	This output becomes TRUE when the command is started with Enable and remains so as long as the function block executes the command.
Error	BOOL	This output becomes TRUE if an error has occurred during command execution.
ErrorId	UDINT	Contains the command-specific error code of the last executed command. Details of the error code can be found in the ADS error documentation or in the NC error documentation (error codes 0x4nnn and 0x8nnn).
GroupMoving	BOOL	The group is in the GroupMoving state (see State diagrams).
GroupHoming	BOOL	The group is in the GroupHoming state (see State diagrams).
GroupErrorStop	BOOL	The group is in the GroupErrorStop state (see State diagrams).
GroupNotReady	BOOL	The group is in the GroupNotReady state (see State diagrams).
GroupStandby	BOOL	The group is in the GroupStandby state (see State diagrams).
GroupStopping	BOOL	The group is in the GroupStopping state (see State diagrams).
GroupDisabled	BOOL	The group is in the GroupDisabled state (see State diagrams).
AllAxesStanding	BOOL	None of the axes in the group move physically (velocity = 0 and acceleration = 0), regardless of whether a Motion Command exists or not.
ConstantVelocity	BOOL	Not supported. Not visible as of TF5400 3.2.27.
Accelerating	BOOL	Not supported. Not visible as of TF5400 3.2.27.
Decelerating	BOOL	Not supported. Not visible as of TF5400 3.2.27.
InPosition	BOOL	Not supported.
