Safety message for series commissioning under Safety Integrated Extended/Advanced
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. To
acknowledge the Safety message, you must first manually correct the serial number for the
absolute encoder, e.g. with Startdrive. The description can be found in Section "Information
pertaining to component replacements (Page 371)". You can then carry on with the
commissioning.
