;Maximum grinding wheel peripheral speed (as $TC_TPG7)
TOOLGRINDmaxTipSpeed=0
;Inclination angle of inclined wheel (as $TC_TPG8)
TOOLGRINDinclAngle=0
;Compensation parameter for grinding wheel peripheral speed (as
$TC_TPG9)
TOOLGRINDparamNrCCV=3
Note
The HMI Advanced function "Change tool" used up to now is not modified. Therefore, with
grinding tools too, when the tool type is changed, most tool data is set by the HMI to "0".
The grinding-specific tool data is not set to "0"; instead it is processed by the NCK.
