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
