Description: Sets the fine resolution in bits of the incremental position actual values.
Note: The parameter applies for the following process data:
- Gx_XIST1
- Gx_XIST2 for reference mark or flying measurement
The fine resolution specifies the fraction between two encoder pulses. Depending on the physical measurement
principle, an encoder pulse can be broken down into a different number of fractions (e.g. squarewave encoder: 2 bit =
resolution 4, sin/cos encoder: Typical 11 bit = resolution 2048).
For a squarewave encoder, with the factory setting, the least significant bits have the value zero, i.e. they do not
supply any useful information.
For especially high quality measuring systems, the fine resolution must be increased corresponding to the available
accuracy.
