Installation

  1. Plug in the power connector; the box will automatically boot.

    Note

    The power supply has an output rating of 5 VDC, 4000 mA.

  2. The box is connected to the local network via WiFi. You can access OBLAC Drives over the local area network.

  3. Connect the EtherCAT cable to the lower LAN port on the back of the box. Connect this to the SOMANET servo drive on port IN.

Attention

Ensure that the LAN ports are used correctly: The upper LAN port is not used. The lower LAN port is required for EtherCAT communication. When the ports are switched, no communication is possible!

The Box is controlled via WiFi.
