Number of sections within list for leadscrew error compensation.
Description | In the compensation value list for leadscrew error compensation, parameter P-COMP-00020 specifies how many entries were specified in the compensation value list for this type of compensation. During interpretation of that list by the CNC it, is checked if the specified number of list entries exceeds the lower or upper number of entries that are necessary or maximal possible to correctly use the leadscrew error compensation.
Response | Class | 3 | The CNC reaction depends on whether the lower or upper limit for the number of entries in the compensation value list is violated. If the value for P-COMP-00020

- is 0, the CNC uses internally 2 entries, each of which is initialized with 0.
- 1 The CNC internally uses an additional entry initialized with the values of the first entry.
- > upper limit
  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 | Checking 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 [-]

%2: | Error value [-]
Shows 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 by data transfer from parameter list into control device.
