<Program operation>
 Positioning commands are programmed and stored to
the Driver Unit.
 Performs a positioning by the inputs of channel
selection and the program starting command.
 The commands are in the absolute or incremental
position format.
<Jogging operation>
 The Motor rotates to any point by the Jog input and
the Jog direction input.
<Home Return operation>
 Set a current position to the Home position or set the
Home position by Home Return operation started by
the Home position limit input.
 An input of starting Home Return signal executes the
operation.
