Invalid number of sections within list for leadscrew error compensation.
Description | In the compensation value list for leadscrew error compensation, parameter P-COMP-00020 specifies the number of entries that were specified in the compensation value list for this type of compensation. When the CNC interpreted this list, it check whether the parameterised number of entries exceeds the lower or upper number of entries that are necessary or to use the leadscrew error compensation correctly.
Response | Class | 3 | The CNC reaction depends on whether the lower or upper limit is violated for the number of entries in the compensation value list. If the value for P-COMP-00020 is

- 0 The CNC uses 2 entries internally, both initialised by 0.
- 1 The CNC uses an additional entry internally initialised with the values of the first entry.
- > upper limit
  The CNC uses only the maximum number of entries that can be processed (parameter 2 of the error message) for leadscrew error compensation.

Solution | Class | 7 | Check the value in parameter P-COMP-00020. It must be ≥ 2 and ≤ than the value in parameter 2 of the error message.
Parameter | %1: | Logical axis number [-]
Number of entries in the compensation value list for leadscrew error compensation specified by the operator in parameter P-COMP-00020.
%2: | Incorrect value [-]
Indicates how many entries are used for leadscrew error compensation after this message.
%3: | Lower limit value [-]
%4: | Upper limit value [-]
Error type | 2, Error message on data transfer of parameter lists to controller.
