Positioning can be executed with either an absolute value (i.e., to an absolute
position from the origin), or with an incremental value (i.e., to a relative position
from the present position).
In addition, depending on instructions from the PC and interrupt inputs, position-
ing can be executed using either "speed control," in which axes are operated at a
fixed speed for that operation, or "interrupt feeding," in which axes are moved for
the specified amount during speed control and then stopped.
