Modbus Motion Interface
Read_Double(<AxisOrGroupPage>_+_DestinationPosition_d);
Description
The Destination Position register is valid during a motion and indicates the current target position of the move as an absolute coordinate. This value is useful for identifying how far an axis has to go before the move is finished by subtracting the Commanded Position from the Destination Position. For multiaxis moves the Destination Position is the length of the hypotenuse of the vector move being performed. The beginning of the move is 0 and the end is the Destination Position. If a move is retargeted with a move by command while the move is in progress the Destination Position is a way to identify the final target position for that axis.
Escapes
The Destination Position register does not produce any escapes.
Examples
This operation reports the destination position for axis 1:
Value:=Read_Double(Axis1_+_DestinationPosition_d);
