Offset / Scaling (Cplintr, Cplinsc, Cplouttr, Cploutsc) - Siemens SINUMERIK 840D sl Function Manual

5.5.5.14

Offset / scaling (CPLINTR, CPLINSC, CPLOUTTR, CPLOUTSC)

An existing coupling relationship between a following axis and a leading axis can be scaled
and offset.
The effect of these functions on the total setpoint value of the following axes can be viewed
from the following formula:
FA

Note
The scaling and offset values can be defined for each leading axis.
