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 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.
Description: Sets the fine resolution in bits of the absolute position actual values.
Dependency: Refer to: p0418
Note: This parameter applies to process data Gx_XIST2 when reading the absolute value.
Description: Selecting the encoder connection.
Description: Sets the number of rotations that can be resolved for a rotary absolute encoder.
Notice: This parameter is automatically preassigned for encoders from the encoder list and for identify encoder (p0400).
When selecting a catalog encoder, this parameter cannot be changed (write protection). Information in p0400 should
be carefully observed when removing write protection.
