Special features in relation to "Manual Grinding"
If you have interrupted manual grinding (Page 54) with the PLC button "Handwheel", the last
position of the infeed axis can be calculated in the subsequent "Sense workpiece" >
"Calculate position" command.
The following text appears above the HMI:
"Copy setting value from manual grinding - continue with NC start".
Figure 4-15
The calculation is only possible for the infeed axis from manual grinding and also only once
directly after manual grinding. If the "Sense workpiece" command is aborted or a different
axis than the last infeed axis is set, each axis must then be calibrated at freely definable axis
positions.
