To activate the active power-dependent adjustment of the desired voltage
value, you need to set the following parameters:
Activating TDSC
The TDSC function is only active when the device can calculate the active
power (correct current measurement and voltage measurement) and the re-
quired parameters are set. If this isn't done, the voltage is regulated to the
set desired value [►Section 8.12.1.1, Page 139]. You can activate or deacti-
vate the power-dependent adjustment of the desired voltage value as fol-
lows:
▪ Parameter
▪ Digital inputs TDSC on and TDSC off (optional)
▪ Control system command (optional)
If you activate TDSC, the line drop compensation (R&X compensation or Z
compensation) function is deactivated.
To activate/deactivate TDSC using parameters, proceed as follows:
1. Go to Settings > Parameters > Control > Activate TDSC.
2. Select the option you want.
3. Press the Accept button to save the modified parameter.
TDSC Umax/Umin
You can use these parameters to set the maximum and minimum desired
value. The maximum or minimum desired value is activated when the mea-
sured active power reaches the set minimum or maximum active power.
1. Go to Settings > Parameters > Control > TDSC Umax/Umin.
2. Enter maximum/minimum desired value.
3. Press the Accept button to save the modified parameter.
