The following two methods are available for commanding a position in control using
positioning data.
A position based on the OP (absolute address) is specified and positioning control is
performed. This address is regarded as the positioning address. (The start point can be
anywhere.)
The position where the workpiece is currently stopped is regarded as the start point, and
positioning control is performed by specifying movement direction and movement amount.
