Functional description of the encoder

7.13 Offset value
The offset value is calculated in the preset function and shifts the
position value with the calculated value. The offset value is stored
in a non volatile memory and can be read from the encoder at any
time. The data type for the offset value is a 32 bit or 64 bit binary
value with sign, whereby the offset value range is equal to the
measuring range of the device.
The preset function is used after the scaling function. This means
that the offset value is indicated according to the scaled resolution
of the device.
Parameter Meaning Data type
Offset value The offset value for encod-
ers with a measuring range
of maximum 32 bits
Integer 32
Offset value 64 bit The offset value for encod-
ers with a measuring range
exceeding 32 bits
Integer 64
Table 45 Offset value
Note: The offset value is read only and cannot be modified
by a parameter write access.
