What it means
The manuals title this message CU: Internal error (port does not exist)
: an internal error of the CU in which the port object that is assigned, according to the topology, for the requested slave component does not exist. Both entries carry the note Only for internal Siemens troubleshooting
, so this is not a condition meant to be diagnosed further at the drive by the user.
Why it appears
- The port object that is assigned according to the topology for the requested slave component does not exist.
What to check
- Read the fault value in r0949 — interpreted in hexadecimal, it contains the Method ID of the internal error.
- Contact Technical Support; the manuals name no measure to be carried out at the drive itself.
Reading the message value
- The drive stores the fault value in r0949; interpret it in hexadecimal.
- The value is the Method ID of the internal error.
Parameters the manual names
- r0949 — fault value: for this code it carries the Method ID; read it in hexadecimal and quote it when contacting Technical Support.
Acknowledging and restarting
The message is cleared by acknowledging it, and it can be acknowledged straight away — no special reset sequence or waiting time applies. Acknowledging does not remove the cause: record the fault value from r0949 and contact Technical Support, since the manuals give no on-site measure for this internal error.
