Drawing a clockwise arc (for Setting values 0~12 in S
1. Define the four quadrants (QI, QII, QIII and QIV) of a coordinate system as in the graph below. Point A indicates the
current coordinates on the X and Y axes.
2. Point B is the target coordinates specified by S
point B.
3. For PLC with FW V1.04.59 or previous versions, S
V1.04.60 or later, S can also be the distance to shift the center point or central angle, if it is defined as the central
3
angle, it is the included angle of AOB.
4. The point A represents the origin of the axes X and Y in a plane. The target point B can be in Quadrant I, II, III, IV of
the plane. Use the target point B to connect to the point A to draw a line and then use the setting values (shift the
center point or central angle) in S
The figures below show 2 arc-travel path examples (solid lines) when the point B is in Quadrant I and IV with
