Configuring control

In the configuration of the software module, make the following settings in the "Energy storage unit" configuration menu:

  • DC connection to energy storage unit separable – yes
  • Storage connection variant – inrush current limiter
  • Nominal electrostatic capacitance – capacitance of the energy storage unit
  • Output stage side – output stage side of the device to which the energy storage unit is connected.

The inrush current limiter function works completely independently; separate control is not necessary. The digital inputs and outputs of the supply unit can be used. To use the digital inputs and outputs of the supply unit, the following functions must each be assigned to a digital input and output via the Basic device configuration menu:

  • Digital outputs
    • Inrush current limiter – control
  • Digital inputs
    • Inrush current limiter – fuse feedback

If these inputs and outputs are not available, an IOConnector can be used for connection to an external IO system as follows:

  1. Create a local instance of the OConnectorRelayContact function block.
    • MDE90A_IO_connect: SEW_MK_PES_EnergyMode.SEW_PES_EnHubEnMode.SEW_PES_ModeIcl.IOConnectorRelaisContact;
  2. Connect the local instance by calling up the LinkIOExchange method on the software module used (in the example as a local instance "MDE90A"). If necessary, the method returns the correct linking as a Boolean value and must be queried to ensure the linking.
    • MDE90A.LinkIOExchange(
      itfQueryInterfaceSEW := MDE90A_IO_connect);
  3. Connect the MDE90A_IO_connect.xDI_ContactState input and the MDE90A_IO_connect.XDO_Relay Cntrl output to the external IO system to be used.
