Description: Sets the number of rotations that can be resolved for a rotary absolute encoder with activated position tracking of
the load gearbox.
Dependency: This parameter is only of significance for an absolute encoder (p0404.1 = 1) with activated position tracking of the
load gearbox (p2720.0 = 1).
Note: The resolution that is set must be able to be represented using r2723.
For rotary axes/modulo axes, the following applies:
This parameter is preset with p0421 and can be changed.
For linear axes, the following applies:
This parameter is pre-assigned with p0421, expanded by 6 bits for multiturn information (maximum number of over-
flows) and cannot be changed.
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: F07449
Caution: Rotation, e.g. through a complete encoder range is not detected.
Note: The value is entered in integer (complete) encoder pulses.
For p2720.0 = 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: Displays the absolute value after the load gearbox.
Notice: The encoder position actual value must be requested using the encoder control word Gn_STW.13.
Note: The increments are displayed in the format the same as r0483.
