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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 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.

2. 4

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