The sequence cannot be interrupted with a single block.
Example
Oscillation with:
● 0.02 mm infeed depth at the start
● 0.01 mm infeed depth at the end
● Total infeed depth 1 mm
● 100 mm stroke
● Infeed feedrate 1 mm/min
● Transverse feedrate 1000 mm/min

Programming Manual, 12/2019, 6FC5398-2EP40-0BA0
Start of the cycle at the current position of the oscillating axis.
Traversing of the infeed axis to the infeed depth at the start <S_I> with the feedrate for in‐
feed <S_R>.
Sparking out with the sparking-out time <S_P>.
Traversing of the oscillating axis with the grinding width <S_A> as travel path and the feedrate
for transverse infeed <S_F>.
Traversing of the infeed axis to the infeed depth at the end <S_J> with the feedrate for
infeed <S_R>.
Sparking out with the sparking-out time <S_P>.
Traversing of the oscillating axis with the grinding width <S_A> as travel path to the starting point
and the feedrate for transverse infeed <S_F>.
Indicates reiterating sequential steps.
The sequence is repeated until the total infeed depth <S_K> has been reached. The last stroke
is then distributed unevenly.
