B.2.3 Calculating specifications for the measuring reference system
Point of reference Calculation rule
Axis zero point AZ = SZ + a’
Project zero point PZ = AZ + b = SZ + a’ + b
Lower software end position LSE = AZ + d = SZ + a’ + d
Upper software end position USE = AZ + e = SZ + a’ + e
Target/actual position TP, AP = PZ + c = AZ + b + c = SZ + a’ + b + c
Tab.B/10: Calculating rules for the dimension reference system with absolute measuring
systems
Note on absolute measuring systems
When calculating for drives with absolute encoding sensor
(only pneumatic), the axis zero point refers to the sensor zero
point (mounting offset a’ instead of a) All other derived vari
ables are identical.
Reference point
Calculation rule
Axis zero point AZ = REF + a
Project zero point PZ = AZ + b = REF + a + b
Lower software end position LSE = AZ + d = REF + a + d
Upper software end position USE = AZ + e = REF + a + e
Target/actual position TP, AP = PZ + c = AZ + b + c = REF + a + b + c
Tab.B/11: Calculation rules for the measuring reference system with incremental measur
ing systems
Note on incremental measuring systems
The "offset axis zero point" must always be specified as a
negative due to the definition of the axis zero point = cylinder
zero point.
