SI MM: Write request for Safety Integrated parameter rejected

What does 230659 mean?

A write request for one or more Safety Integrated (SI) parameters on the Motor Module (MM) was rejected. This typically occurs because an attempt was made to enable a safety function (like STO, SBC, SS1, motion monitoring, or PROFIsafe) that the specific Motor Module does not support, or there is a version mismatch in PROFIsafe drivers. This fault does not trigger a safety stop.

Complete Troubleshooting Guide

1. 1

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

2. 2

   Confirm that the Motor Module in use explicitly supports the specific Safety Integrated function (STO, SBC, SS1, safe motion monitoring, PROFIsafe) that was attempted to be enabled.

3. 3

   If the function is supported but rejected due to versioning, upgrade the software on both the Motor Module and the Control Unit to compatible versions.

4. 4

   Verify that the PROFIsafe communication is correctly configured and that the PROFIsafe driver versions on the CU and MM match.
