PNU Description
P542 Time difference for dy/dt of ramp-function generator
Ramp-function generator:
FDS
Setting of dt for the output of dy/dt at a connector, i.e. at K0191, the change
in the output quantity of the ramp-function generator (K0190) is output within
(G136)
the period set in P542
Example: - The ramp-function generator is currently ramping up with a
ramp-up time of P311=5s, i.e. a ramp-up operation from y=0%
to y=100% takes 5s.
- A time difference dt of P542=2s is set.
- ⇒ A dy/dt of 40% appears at connector K0191 since the dy
within the set dt of 2 s equals (2s/5s)*100%..
(see also parameter P330)
P543 Threshold for SAD-dependent acceleration
With respect to the SAD-dependent acceleration function, only the
FDS
component of the speed controller setpoint/actual value difference which
has an absolute value in excess of the threshold set in this parameter is
(G153)
switched through (see also parameter P541).
