The sign of the cos phi specified value defines whether the inverter behaves like an over-
or under-excited synchronous machine. The inverter always acts like a generator regard-
ing the flow direction of the active energy:

The cos phi specified value indicates the power factor of the inverter while feeding
power into the grid.
The change gradient indicates the speed at which the inverter will change from the
present cos phi specified value to the new cos phi specified value. The change gradi-
ent can be used to avoid erratic changes between entered values.

Change gradient
big endian | signed int | resolution: 1 LsB = 0.001 [-] |
Value range -999d to -850d and +850d to +1000d
big endian | unsigned int | resolution: 1 LsB = Delta 0.001 [-]
/ sec |
Value range 1-15000d / Special value: 0xFFFF is defined as
"as fast as possible"
Example: Change from -0.850 to +0.850 corresponds to a
Delta of 300. A change gradient of 15000 entails a change
from -0.850 to +0.850 in 0.02 seconds (calculation: Delta/
Change gradient = 300/15000 = 0.02 seconds)
