U327 (0) Operating mode for rounding
0: Final rounding does not act upon sudden reduction
of the input value during acceleration
1: Rounding always acts (except when output limitation
has responded). If there is a sudden reduction of the
input value, overshooting can occur.
Selection of function data set
for comfort ramp-function generator
<1> At U328 = 552 the RGen only acts once in each case after enabling (^ edge)
<2> Effective accel.time: Tup_eff = Tup * adaption factor + (AR/2 + ER/2)/adaption factor
Effective decel.time: Tdn_eff = Tdn * adaption factor + (AR/2 + ER/2)/adaption factor
(If adaption is used, the jerk remains the same)
<3> Ramp-function generator is tracked when a limitation responds (y:=RGen output)
<4> Rounding and adaption do not act with the 'min' or 'h' unit for accel./decel. time
<5> Rounding also acts during a zero passage
