F01683

SLS enable missing

Siemens · SINAMICS G120 Safety Functions

What does F01683 mean?

The Safely Limited Speed (SLS) function is not enabled, even though it's required or configured for the application. This prevents the system from limiting speed safely, potentially leading to hazardous overspeed conditions if the drive operates outside its safe limits.

Complete Troubleshooting Guide

  1. 1

    Enable the SLS function (p9501.0).

  2. 2

    Save the setting by copying RAM to ROM.

  3. 3

    Cycle the power supply of the Control Unit (off then on).
