Safety parameter changed

What does A01690 mean?

A safety-related parameter has been modified either during safety commissioning or a safety reset. This warning is issued to ensure that all safety changes are intentionally acknowledged and finalized, as unresolved changes can prevent the drive from entering a safe operational state, potentially compromising machine safety.

Complete Troubleshooting Guide

1. 1

   Conclude the safety commissioning by setting parameter p3900 to 10 (accept changed parameters) or 11 (discard changes).

2. 2

   If a safety reset was performed, wait for its completion before proceeding with operations.

3. 3

   Review all changed safety parameters to confirm they are set as intended and meet safety requirements.
