E14 Factor for P13 and P16
(nur bei Kartenausf. für Regelkreise)
P13 or P16 * Factor 1 0
P13 or P16 * Factor 1 1
P13 or P16 * Factor 2 2
P13 or P16 * Factor 4 4
P13 or P16 * Factor 8 8
P13 or P16 * Factor 16 16
Select 0 for internal closed loop, values
1 to 16 for external closed loop. E 14 is
automatically zeroed if E2 = 0 or E2 = 3 is
set. On the other hand, E2 = 3 can be set
if E14 ≥1. The factor from E14 then only
affects P16 and not P13. The changeover
in structure by E14 is carried out.
If E14 ≥1 and E2 = 3 the safety function
is not active.
