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.
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 number
with 23 bit mantissa).
Description: Sets the number of relevant bits for the redundant coarse position value.
Description: Sets the bit number for the safe most significant bit (MSB) of the Gx_XIST1 coarse position.
Note: MSB: Most Significant Bit
Description: Sets the non safety-relevant measuring steps of POS1.
Dependency: Refer to: r0473
