DPI Port Communication Loss

Was bedeutet 81-85 ?

A DPI port has stopped communicating, or a SCANport device was connected to a drive operating DPI devices at 500k baud. This indicates a loss of communication with a connected DPI device, which can prevent control commands or feedback from reaching the drive. The fault code varies depending on which port (1-5) lost communication.

• Loss of communication on the DPI (Drive Parallel Interface) port.
• Faulty DPI cable connection.
• Incorrect DPI addressing or configuration (e.g., P8-xx parameters).
• Communication failure with the connected device on the DPI bus.
• DPI device not powered or malfunctioning.

1. 1

   If the adapter was not intentionally disconnected, check the wiring to the affected DPI port.

2. 2

   Check the HIM (Human Interface Module) connection.

3. 3

   If an adapter was intentionally disconnected and the [Logic Mask] bit for that adapter is set to "1", set the [Logic Mask] bit for the adapter to "0" to disable this fault.

4. 4

   Replace wiring, port expander, adapters, or Main Control Board as required.
