Hello,
The Motor has a special Encoder which is Buffered via a Batterie in the ACOPOSmicro (Behind plastic next to Powerlink Node Number, sperate Ordernumber).
If this is the first time you power on the system you must acknowledge a special Encoder-Power-Monitoring used for this drives to supervice the status of the Batterie Supply. These Encoders are called EIB Encoder. In B&R naming B1-Option. Every time the Encoder is cut of the supply (low Batterie, no EncoderCable connected) it had to be reset again.
To reset this encoder Error you have to set ParID 719 to Value 1.
After you set Power to TRUE you should have got and StatusID <> 0 on the MappAxisBasic Functionblock. This would have indicated the Error. The Fuctionblock has no Error Details, the are found in Logger or with special Error Text Fuctionbocks.
For General Diagnosis on the Motion System i suggest you to always use the MappCockpit first, if you find there no clue continue with the Motion Logger in Automation Studio.
The SDM Axis Info does only work for ACP10 legacy Drive System and not for MappMotion.
Here are also good steps to get an Axis to Operational.
Greetings
Michael
