3.4.14 Offset value
The offset value is calculated by the preset value function and shifts the position value by the calculated
value. The offset value is stored in the encoder and can be provided by the diagnostic octets 32 to 35. The
data type for the offset value is a 32-bit binary value with sign. The offset value range is equal to the
measuring range of the encoder.
The preset value function is used after the scaling function. This means that the offset value is indicated
according to the scaled resolution of the encoder.

3.4.15 Offset value of the manufacturer of the encoders
The offset value of the manufacturer of the encoder indicates the offset value set by the manufacturer.
This value gives information on the shift of the position zero point to the physical zero point of the
encoder. The data type for the offset value is a 32-bit binary value with sign. The value range corresponds
to the measuring range of the encoder. The offset value of the manufacturer of the encoder is indicated in
the number of units according to the basic resolution of the encoder. The value is stored in the memory
which is protected against writing and can only be changed by the manufacturer of encoder. This value
has almost no importance for the user.
