SI CU: Control Unit software incompatible

What does 230672 mean?

The existing Control Unit software does not support the safe drive-based motion monitoring function, leading to a STOP A that cannot be acknowledged. The fault value (r0949) is typically for internal Siemens troubleshooting. This indicates a fundamental incompatibility between the CU's software version and the attempted safety function.

Complete Troubleshooting Guide

1. 1

   Check for any related safety function alignment faults (F01655, F30655) between the Control Unit and Motor Module and carry out diagnostics if present.

2. 2

   Confirm that the specific Control Unit model and its current firmware version are officially capable of supporting the safe drive-based motion monitoring function.

3. 3

   Upgrade the Control Unit software to a version that provides full support for the required safe motion monitoring functionality.

4. 4

   If necessary, consult Siemens documentation or support to ensure hardware and software compatibility for the desired safety functions.
