This parameter reports the slot number into which the module is fitted.
The top 16-bits are scaled to 65536 counts per revolution regardless of the type of
feedback device or scaling configured in the drive.
This parameter gives the feedback encoder marker revolution count.
The database version number is read from the database after power-up
