Cause : Port 5 DPI Loss comes when communications between the drive and the Modbus or DSI master device have been interrupted. DPI port stopped communicating. A SCANport device was connected to a drive operating DPI devices at 500k baud. The DPI port stopped communicating.
- If adapter was not intentionally disconnected, check wiring to the port. Replace wiring, port expander, adapters, Main Control Board, or complete drive as required.
- Check HIM connection.
- If an adapter was intentionally disconnected and the [Logic Mask] bit for that adapter is set to “1”, this fault occurs. To disable this fault, set the [Logic Mask] bit for the adapter to “0.”
