A_SR, A_SL, A_FSL (allowance)
For the various machining steps, different values can be defined for the allowance. These
refer to the nominal diameter.
A_SR Roughing allowance
A_SL Finishing allowance
A_FSL Fine-finishing allowance
SLZ (infeed amount for finishing), FSZ (infeed amount for fine-finishing)
When grinding by reciprocating, the wheel is fed in at the reversal points, depending on the
machining type (finishing or fine-finishing). The infeed amount is programmed with the
parameters SLZ and FSZ.
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 BU2 (dwell 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_PE, F_SR, F_SL, F_FSL (feedrate)
Different feedrates can be specified for the individual machining steps. They are
programmed in [mm/min].
F_PE Feedrate for reciprocating in Z
F_SR Feedrate for roughing
F_SL Feedrate for finishing
F_FSL Feed rate for fine finishing
