Note: When actual position reference values are measured, all

machine parts have to have reference temperature!

All temperature data are scaled with the temperature scaling (S-0-0208)

set on the drive side. The factors for linear expansion (P-0-0406,

P-0-0407) are scaled with the quotient position data scaling/temperature

scaling (S-0-0076/S-0-0208).

Position-Independent Temperature Correction

The position-independent temperature correction is used to compensate

the temperature-dependent linear expansion of tools, workpieces and

slides. The expansion of these components of a servo axis only depends

on the temperature difference compared to a reference temperature, the

resulting actual position value error is the same at each position of the

axis.

Pertinent parameters:

• P-0-0402, Axis correction reference temperature

• P-0-0405, Axis correction actual temperature pos.-independent

• P-0-0407, Axis correction temperature factor pos.-independent
