[Function]
Upon detection of the signal edge for executing the position command when the new data is in normal state, the content
of the position number register will be read and positioning will be performed to the target position of the corresponding
position data.
If the position start command for the new data remains ON, the position complete signal (PEND) will not be output even
when the actuator enters the positioning band. However, the completed position number signal (PM***) will be output.
If this command is executed when no home return operation has been performed after the power on (when HEND = “0”),
the actuator will perform home return operation and then start moving to the target position.
