Cancelling the NC operation is only possible with the emergency stop button or by switching off

Steps in the HMI
The automatic downward feed of the grinding wheel can be activated by at least one rough
grinding number (1) if the fine grinding number (2) is not set to 0.
In the automated surface grinding mode, the grinding wheel is automatically infeed after each
pass in the transverse axis. This requires entries for the number of coarse grindings (1) and at
least one fine grinding (2).
After completion of the entered number of sequence steps, "sparking out" occurs without infeed
of the grinding wheel. The grinding head is then raised and the hydraulic pump is switched off
to stop the oscillating movement of the table.
