Explanation
 ABST enables an absolute coordinate system. An Absolute coordinate is a
coordinate starting from 0. If the target position of an axis is greater than the
present position of the axis, the motor for the axis will rotate clockwise. If the target
position of an axis is less than present position of the axis, the motor for the axis
will rotate counterclockwise.
 INCT enables a relative coordinate system. A relative coordinate is relative
movement from the present position of an axis. If the relative coordinates used are
positive values, the motor used will rotate clockwise. If the relative coordinates
used are negative values, the motor used will rotate counterclockwise.
 The center point (I, J), the radius (R), and the additional distances set by SINTR
and DINTR are regarded as relative increments.
Example
 If ABST and INCT are not in the program in a DVP-20PM series motion controller,
the default setting for the program will be an absolute coordinate system after the
STOP/RUN switch of the DVP-20PM series motion controller is turned form the
“STOP” position to the “RUN” position. After INCT is executed, the motion
instructions starting from the next row (e.g. DRV, LIN, CW, and CCW) will be
operated in a relative coordinate system.
