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 1/2/3 [►Section 9.16.1.2, Page 177]. You can activate or
deactivate the power-dependent adjustment of the desired voltage value as
follows:
▪ Parameter
▪ Digital inputs TDSC on and TDSC off (optional)
▪ Control system command (optional)
