SRZ, SLZ, FSLZ (infeed amount for roughing, finishing and fine-finishing)
When grinding by reciprocating, the wheel is fed in at the reversal points, depending on the
machining type (roughing, finishing or fine-finishing). The infeed amount is programmed
using the parameters SRZ, SLZ and FSLZ.
ZU_ART (infeed)
When grinding by reciprocating, the wheel is fed in at the reversal points. The ZU_ART
parameter is used to define whether an infeed by the infeed amount is to be performed only
at the left, at both or at the right reversal point.

BVU1 and BVU2 (holding time at the reversal point)
The dwell time at reversal point 1 or 2 can be defined using the following value:
"0 = Wait for exact stop fine and then wait for stopping time to elapse
The unit for the dwell time is given in workpiece speed after infeed.
F_SR, F_SL, F_FSL (feedrate)
Different feedrates can be specified for the individual machining steps. They are
programmed in [mm/min].
F_SR Feedrate for roughing
F_SL Feedrate for finishing
F_FSL Feed rate for fine finishing
N_FR (number of sparking-out strokes)
Once the finished dimension is reached when grinding by reciprocating, a number of
additional reciprocation strokes are performed without further infeed of the wheel. These
strokes are called 'sparking-out strokes'. The number of the sparking-out strokes is defined
in the N_FR parameter.
