Number of data bits
When you configure an axis in S7T Config, you must specify the "number of data bits" for the
encoder.
The "number of data bits" corresponds to the proportion of user data of the 32-bit wide
encoder actual value, and is calculated from the sum of the data bits for the encoder and
multiturn resolutions.
To display the position correctly, the values set in S7T Config must agree with the values
configured in the drive.

Note
In firmware version 4.1 or later, the values from the drive can be transferred to the axis
configuration at the press of a button in S7T Config.
