S af ety message for standard commissioning with S afety Integrated Extended Functions
If third-party motors with absolute encoders are being used, a situation may arise where a
Safety message prevents commissioning.
One reason for this may be that a different serial number of the absolute encoder is saved
on the memory card than that in the Control Unit which is to be commissioned. The Safety
message can only be acknowledged once the serial number for the absolute encoder has
been corrected manually (e.g. with STARTER). The description can be found in Section
"Information pertaining to component replacements (Page 361)". You can then carry on with
the commissioning.
