35. 55 1 Fundamentals of Positioning Fundamentals of Positioning Position feedback The position feedback encoders convert the movement of the ma chine 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 Fig 8 Linear position encoder here for the X Reference marks i The scales of the position encoders contain one or more reference marks When a reference mark is passed over it generates a sig nal which identifies that position as the reference point scale ref erence point machine reference point With the aid of this refer ence mark the POSITIP s REF feature re establishes the assign ment 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 need only move a maximum of 20 mm 0 8 in for linear encoders and 20 for angle encoders Fig 9 Linear scales with distance coded ref erence marks upper illustration and one reference mark lower illustration Angle reference axis
