Wrong safety checksum

What does F01660 mean?

This fault occurs when checksums related to safety commissioning are inconsistent, preventing the drive from exiting the commissioning state. This indicates that safety parameters in p9798, p9799, p9898, or p9899 do not match as required, signaling a configuration error that must be resolved for safe operation.

Complete Troubleshooting Guide

1. 1

   Verify that checksums in p9798 and p9898 are identical; if not, ensure parameterization (p96xx = p98xx) is consistent.

2. 2

   Set the checksum in p9799 or p9899 correctly to match the required values.

3. 3

   If checksum correction is unsuccessful, exit safety commissioning by setting p3900 = 11 to cancel.
