Reference Description
Settling time
[
VArPct_RmpTms]
200 – 60000 [ms]
Determines the dynamic behaviour in the event
of a change in the active power set value. The
active power is changed according to a PT-1
characteristic curve with a settling time of
5 Tau.
NOTE: The settling time is overlaid with the in-
creasing and decreasing gradient.
Settling time
[
VArPct_RmpTms]
1000 [ms]
Non-configurable settings 1 s.
If the applicable grid connection guidelines call for the active power to be adjusted to the target value with a defined
gradient or a defined settling time, then the device can be configured in such a way that this gradient is adhered to. In ad-
dition, the gradient can also be implemented on the plant controller. This second solution is to be used for all other in-
verters.
Limitation of power gradients
The power reduction parameters can be adjusted in SunSpec model DID123. During this process, you should also check
whether internal and/or external power reduction is active.

Sample parameters for power limitation
If the ramp time
“WMacLimPct_RvrtTms”
in the SunSpec model is specified as 0 s, then the internal output gradient
is used. Otherwise, the set value will be used.
Irrespective of the communication protocol used, the settling time
“WMaxLim_Ena”
is used in order to transfer the new
power value. Otherwise, the internally configured value will be used.
The additional ramp time “
WMacLimPct_RmpTms”
specifies the jump time from a power value to the new power
value.
The following formulae are used to calculate the gradient S
