K3: Compensations
4.2 Temperature compensation
Temperature compensation type and activation
The temperature compensation type is selected and the temperature compensation
activated using the axis-specific machine data:
MD32750 $MA_TEMP_COMP_TYPE (temperature compensation type)

Maximum compensation value per IPO clock cycle
The maximum possible compensation value per IPO cycle, i.e. the maximum distance that
can be traversed in an IPO cycle as a result of the temperature compensation, is limited
using machine data:
MD32760 $MA_COMP_ADD_VELO_FACTOR (velocity increase as a result of
compensation)
The specified value acts as a factor and is referred to the maximum axis velocity (MD32000
$MA_MAX_AX_VELO).
MD32760 also limits the maximum gradient of the error line (tan ß) of the temperature
compensation.
