Target Address Change Function

This function changes the target address of the positioning operation to the specified target address.
When the positioning operation is started, the value of the target address I (BFM#18, #17) is written to the
target address change value (BFM#54, #53). Then, when a new value is written to the target address change
value, the target address changes.
In case of the 2-speed positioning operation, the value of the target address II (BFM#22, #21) is written to the
target address change value after the completion of the 1-speed operation. Then, when a new value is written
to the target address change value, the target address changes.
Point
When the target address is changed by specifying the relative address, the relative travel distance from the
start position of the positioning operation changes. When the 2-speed is changed in the 2-speed positioning
operation, the relative travel distance from the 2-speed start position changes.
It is not the travel distance from the target address change position.
