Fig. 3−11 Measuring systems for absolute positioning in default setting (C1225=0, C1227=0)
In default setting the reference point = machine zero = real zero ( 3−34).
Reference point
l The reference point is the reference for the connection" of the measuring systems with the
machine.
l Is detected through referencing".
Machine measuring system
l The permissible travelling range for the machine measuring system is determined through the
position limit values (C1223 and C1224).
l The machine measuring system has a fixed reference to the machine because of the reference
point.
l The reference point is detected by a reference run" or setting reference" and, usually, not
shifted later. ( 3−46).
Real measuring system
l All indications (e.g.: target positions, position setpoint, and actual position) refer to the real
zero of the real measuring system.
l The real measuring system can be shifted by entering a reference measuring offset.
