2.2 List of parameters
Description: Sets the comparison algorithm for the encoder position monitoring functions.
Value: 0: SMx20 safety algorithm
10: DQL binary safety algorithm
11: DQL linear non-binary safety algorithm
12: SMC30 safety algorithm
255: Safety algorithm unknown
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.
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.
