■Function description
This FB changes the current position of the specified axis.
• When Relative is TRUE, the current position is changed to the position obtained by the addition of the target position
(relative distance) and the current position.
• When Relative is FALSE, the current position is changed to the target position (absolute position).
• This FB is executed when Execute turns TRUE, and Busy turns TRUE when the processing is normally started.
• When the processing is completed and the current position is changed, Done turns TRUE.
• After starting this FB when ExecutionMode turned "1: mcQueued", if the axis status (AxisName.Md.AxisStatus) turns "0:
Disabled" / "1: ErrorStop" before processing completion, an error will occur.
• When an error has occurred in the FB, this FB turns Error to TRUE and stores an error code in ErrorID.
• For details of error codes, refer to the following.

Precautions
A current position change can be executed during axis operation. If the current position is changed during axis operation, the
target position of the on-going FB will not change, but since the current position is changed, the operation to the target value
will be changed.
