NOTE
When filling in a rectangle from the Zigzag Start Point to the Rectangle End Point, if the Z
coordinates for the Zigzag Start Point and the Rectangle End Point differ, the robot changes the
height of the Z axis so it dispenses on a slope while it executes dispensing.
With other dispensing operations, the robot dispenses from the start point Z coordinates in a
horizontal plane.

 Rectangular Spiral Start Point – Rectangle End Point
The robot spirals from the Rectangular
Spiral Start Point toward the center, and
does so by executing line dispensing at
the specified [Line
horizontal plane at the Rectangular
Spiral Start Point.
The robot draws the spiral by splitting up
the shorter X or Y direction distance (L in
the diagram to the right) according to the
number of pitches
Rectangular Spiral Start Point to the
Rectangle End Point.
(L) ÷ (N) = (d)
Also, the robot dispenses along the
longer X or Y direction. With the diagram
above and to the right, the horizontal
direction is longer than the vertical
direction (L), and therefore spirals in a
clockwise direction. With the diagram to
the right, this is the opposite.
