Constant relati-
VArMaxPct (17) to VArPct_Ena (23)
ve reactive
These registers can be used to set on the inverter a constant value for the reacti-
power
ve power to be produced by the inverter.
VArMaxPct (17)
-
-
NOTE!
In practical operation, the reactive power that is actually available is speci-
fied by the inverter's operating limits.
For this reason, the reactive power specification can only be reached if enough
effective power is fed into the grid.
If too little effective power is fed into the grid, the inverter will operate at its
operating limit.
VArPct_WinTms (19), VArPct_RvrtTms (20)
These registers can be used to control the inverter's time response for this ope-
rating mode. => See section "Time response of the supported operating modes".
0 is set as the default for all registers.

VArPct_Ena (23)

NOTE!
To change values in an active operating mode (e. g.
to set a different reactive power or a different return time), proceed as follows:

Used to set a value for constant reactive power.
The minimum and maximum limits depend on the type of inverter.
This register cannot be changed.
It returns the (currently) supported operating mode.
Reactive power as a percentage of the maximum possible reactive power.
Enter value 1 into register VArPct_Ena = start operating mode
Enter value 0 into register VArPct_Ena = end operating mode.
Enter the new value into the relevant register
Restart the operating mode using register VArPct_Ena by setting a 1.
the relative approximation value in %/s
Enter the relative reactive power value in register VArMaxPct
(e.g., 80 for 80%).
As an option, you can set the start and return time using registers
VArPct_WinTms and VArPct_RvrtTms.
Start the operating mode by entering 1 in register VArPct_Ena.
