Q Priority When the maximum apparent power is
reached, the setting "Q Priority" leads to a
reduction of the effective power in favour
of reaching the reactive power specifica-
tion.
P Priority The setting "P Priority" leads to a reduc-
tion of the reactive power in favour of
reaching the available effective power
when the maximum apparent power is
reached.
0 ‑ 1
Minimum cos φ, which together with the
maximum apparent power forms an addi-
tional limitation of the reactive power at
low effective power.
