DSI Net Loss

What does F071 mean?

Control over the Modbus or DSI communication link has been interrupted, meaning the drive has lost communication with its master controller via the DSI port. This prevents remote commands and monitoring, potentially causing the drive to fault or transition to a safe state based on its parameter settings.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify the Modbus or DSI setting parameters in the drive (e.g., address, baud rate, parity) match the master device's configuration.

2. 4

   Check the Modbus or DSI status from the master device or a diagnostic tool to confirm communication health.
