2.2 List of parameters
Description:
Sets the number of rotations that can be resolved for a rotary encoder with activated position tracking of the
measuring gear.
Dependency:
This parameter is only of significance for an absolute encoder (p0404.1 = 1) with activated position tracking (p0411.0
= 1) and for an incremental encoder with activated position tracking (p0411.3 = 1).
Note:
The resolution that is set must be able to be represented using r0483.
For rotary axes/modulo axes, the following applies:
p0411.0 = 1:
This parameter is pre-set with p0421 and can be changed.
p0411.3 = 1:
The parameter value is pre-set to the highest possible value. The highest possible value depends on the pulse
number (p0408) and the fine resolution (p0419).
For linear axes, the following applies:
p0411.0 = 1:
This parameter is pre-assigned with p0421, expanded by 6 bits for multiturn information (maximum number of
overflows) and cannot be changed.
p0411.3 = 1:
The parameter value is pre-set to the highest possible value. The highest possible value depends on the pulse
number (p0408) and the fine resolution (p0419).
Description:
Sets a tolerance window for position tracking.
After the system is switched on, 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 fine resolution in bits of the incremental position actual values.
