I - 1 Fundamentals of Positioning Fundamentals of Positioning Position feedback The position feedback encoders convert the movement of the machine axes into electrical signals. The POSITIP constantly evaluates these signals and calculates the actual positions of the machine axes, which it displays as a numerical value on the screen. If there is an interruption in power, the calculated position will no longer correspond to the actual position. When power is restored, you can re-establish this relationship with the aid of the reference marks on the position encoders and the POSITIP's reference mark evaluation feature (REF). Reference marks The scales of the position encoders contain one or more reference marks. When a reference mark is passed over, it generates a signal which identifies that position as the reference point (scale reference point = machine reference point). With the aid of this reference mark the POSITIP's REF feature re-establishes the assignment of displayed positions to machine axis positions which you last defined by setting the datum. If the position encoders feature distance-coded reference marks, each axis needs only move a maximum of 20 mm (0.8 in.) for linear encoders, and 20° for angle encoders. Angle reference axis For angular positions, the following reference axes are defined: Plane Angle reference axis X Y +X Y Z +Y Z X +Z Positive direction of rotation is counterclockwise if the working plane is viewed in negative tool axis direction (see fig. 10). Example: Angle in the working plane X / Y Angle Corresponds to the... + 45° ... bisecting line between +X and +Y +/– 180° ... negative X axis – 270° ... positive Y axis Fig. 8: Linear position encoder, here for the X axis Fig. 9: Linear scales: with distance-coded reference marks (upper illustration) and one reference mark (lower illustration) POSITIP 855 Operating Instructions 11 Y Z –270° Y +45° +180° –180° Fig. 10: Angle and the angle reference axis, e.g. in the X / Y plane X X
