Maximum distance for zero pulse search is smaller than the encoder range.
Description | The maximum distance set in the parameter P-AXIS-00404 for zero pulse search or to search for encoder overflow is smaller than the distance covered by an encoder revolution. The distance covered in an encoder revolution can be defined by:

1. When the parameters P-AXIS-00092, P-AXIS-00362 and P-AXIS-00363 are used to parameterise path resolution, the parameter P-AXIS-00092 contains the number of encoder increments per motor revolution.
2. When homing on encoder overflow, the number of increments per encoder revolution is defined by the minimum value of P-AXIS-00355 and the modulo range (P-AXIS-00126 and P-AXIS-00127) of the axis.

Response | Class | 5 | Correct the value of P-AXIS-00404 to the distance the axis moves during an encoder revolution; output of a warning.
Solution | Class | 1 | Correct the value of P-AXIS-00404 so that the axis can travel at least one encoder revolution during the zero pulse search.
Parameter | %1: | Logical axis number [-]
Axis number of axis, see P-AXIS-00016).
%2: | Current value [0.1 µm or 0.0001°]
Distance moved within one encoder revolution.
%3: | Error value [0.1 µm or 0.0001°]
Set value of P-AXIS-00404.
%4: | Corrected value [-]
Corrected value of P-AXIS-00404.
Error type | 6, Error message by data transfer to control device.
