2.6.2 Calculation rules
Dot Calculation rule
Axis zero point AZ = REF + a
Project zero point PZ = AZ + d = REF + a + d
Negative software end position SLN = AZ + b = REF + a + b
Positive software end position SLP = AZ + c = REF + a + c
Target position/actual position TP, AP = PZ + g = AZ + d + g
= REF + a + d + g
