USB communication fault

What does E.USB mean?

This USB communication fault stops the inverter output if communication is interrupted for a duration longer than specified by Pr. 548 (USB communication check time interval). It indicates a loss of data integrity or physical connection over the USB link. This prevents remote control or monitoring via USB.

1. 1

   Inspect the USB communication cable for damage, loose connections, or improper routing.

2. 2

   Check the Pr. 548 (USB communication check time interval) setting and ensure it is appropriate for the application.

3. 3

   Consider increasing the Pr. 548 setting, or change it to "9999" to disable the communication check if the application allows.
