    (0-8). All the potentially available SINAMICS DCP units are set up in the hardware configuration of the ESS IF PLC as standard. This is a basic requirement for use of the SIMOCRANE ESSM Step7 library. Should only 2 SINAMICS DCPs be physically present, for example, enter a 2 here. Unused devices in the hardware configuration are deactivated during startup.

  • Page 51: Indroopvaluesdcps[%]

    Droop control makes parallel connection possible. The droop value determined by the energy storage system [%] (p.54127) must be signaled to SIMOCRANE ESSM. This causes a voltage correction to be applied which is dependent on the actual system power. This is necessary in order to compensate for voltage fluctuations in the DC link due to operation in droop control.
