8.4.1  Meaning of the “Grind” parameter 

  “Correction value grinding return”: The positioning time of the cycle times will be added 

up and provides the basis for the return time. In order to compensate for imprecision, a 
correction value on the return time for return runs is entered when changing segments. 
The correction value is added to the total lead time. 

  “Disable knife feed during left move”: true = reset knife feed disabled, false = reset knife 

feed enabled 

To change the parameter, tap on the respective field highlighted in yellow. The window (8-13) 
opens for “Number”, the window (8-14) for “Values”.

Select the desired number and confirm with “OK” 
(8-13/1).

The touch panel field “Cancel” closes the window 
without recording the number.
