Description: Sets a tolerance window for position tracking.
After the system is powered-up, the difference between the saved position and the actual position is determined,
and depending on this, the following is initiated:
Difference within the tolerance window --> The position is reproduced as a result of the encoder actual value.
Difference outside the tolerance window --> An appropriate message is output.
Dependency: Refer to: F31501, F32501, F33501
Caution: Rotation, e.g. through a complete encoder range is not detected.
Note: The value is entered in integer (complete) encoder pulses.
For p0411.0 = 1, the value is automatically pre-assigned quarter of the encoder range.
Example:
Quarter of the encoder range = (p0408 * p0421) / 4
It is possible that the tolerance window may not be able to be precisely set due to the data type (floating point num-
ber with 23 bit mantissa).
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 incremental position actual values.
