Activating the Speedwire communication display

By activating this diagnostic function, the product can signal how many network cables are connected by the blue LED flashing. This lets you quickly check the following items:

  • Is the network cable plugged in for products where only 1 network cable is to be connected?

  • Is only 1 network cable connected for products where 2 network cables are to be connected?

Procedure:

  1. In the parameter group Device > Operation, select the parameter Ethernet link diagnostic via LED and set this to On.
  2. Blue LED glows (2 s on and 250 ms off): 2 network cables are connected to the inverter.
  3. Blue LED flashes (2 s on and 250 ms off): 1 network cable is connected to the inverter.
  4. Blue LED is not flashing: No network cable is connected.
  5. Check whether for the products where the blue LED is not flashing there really should not be a network cable connected.
  6. Check for the products where the blue LED is flashing whether there should actually only be 1 network cable connected or whether 2 network cables should be connected here.
