Referencing with distancecoded reference markers
18.3.1
General information
Distance-coded reference markers
Measuring systems with distance-coded reference marks consist of two parallel scale tracks:
●
Incremental grating
●
Reference mark track
The distance between any two consecutive reference markers is defined. This makes it
possible to determine the absolute position of the machine axis when two consecutive
reference marks are crossed. For example, if the distance between the reference marks is
approx. 10 mm, a traverse path of approx. 20 mm is all that is required to reference the
machine axis.
Referencing can be performed from any axis position in the positive or negative direction
(exception: end of travel range).
18.3.2
Basic parameter assignment
Linear measuring systems.
The following data must be set to parameterize linear measuring systems:
●
The absolute offset between the machine zero point and the position of the first reference
mark of the linear measuring system:
MD34090 REFP_MOVE_DIST_CORR (reference point/absolute offset)
See also below: Determining the absolute offset
●
Orientation of the length measuring system (equidirectional or inverse) relative to the
machine system coordinate system:
MD34320 ENC_INVERS (linear measuring system inverse to the machine system)
