CYCLE758 - Change a parameter value

CYCLE758 changes individual strategy and measuring settings prior to the optimization or the
optimization results after the optimization.
Syntax
CYCLE758(<S_I_AXIS>, <S_I_PARAMID>, <S_I_MEASTYPE>, <S_I_MEASINDEX>,
<S_SZ_NEWVALUE>)
Parameters
No. Parameters
1
<S_I_AXIS>
Meaning: Machine axis number (not relevant for parameters that affect the optimization of the path interpolation!)
Data type: INT
2
<S_I_PARAM
ID>
Meaning: ID number of the parameter whose value should be changed
Parameter IDs, see "List of the parameters for the automatic servo optimization (Page 529)".
Data type: INT
3
<S_I_MEASTYPE>
Meaning: Measuring type to which the parameter refers (relevant only for measuring parameters!)
Uniquely identifies measuring parameters with the same ID number.
Data type: INT
Value: 1 =
2 =
3 =
4 =
5 =
4
<S_I_MEASINDEX>
Meaning: Measurement index to which the parameter refers (relevant only for measuring parameters!)
Uniquely identifies measuring parameters with the same ID number that refer to the same measuring
type. It must be specified only when multiple measurements of a measuring type exist.
Data type: INT
5
<S_SZ_NEWVALUE>
Meaning: New parameter value
Data type: STRING [20]
12.3.9

CYCLE759 - Read parameter value

CYCLE759 reads the strategy and measuring parameters and the optimized controller
parameters. This is useful for checking the file loaded with CYCLE752 prior to the optimization
or reading the results after the optimization (e.g. determined total inertia, determined gain).
