Why is the Altivar21 not communicating with mod scan with a bundle of Modbus address (e.g. No Share data of register 464001 to 464020, but it is sharing single one individually)?

The register numbers 464001 to 464020 are not available in ATV21 drive, hence you may find error while checking with modscan.

Refer to the attached Modbus manual for the register details of various drive control and monitoring parameters. 
The registers numbers are not continuous, hence if you poll the register number, which is not available in ATV21 drive, it will give error.
