FAK - Length Scaling Factor
or
Multiplication Factor
Input: from 0.000000 to 1.999999
Axis: 1
Positioning travel of the ’POA,’ ’POI,’ ’PSI’ and ’PSA’ commands is always
the result of a preselected linear value or position and a multiplication
factor.
The formula below applies for incremental positioning:
FactortionMultiplicaLengtheselected Pr=LengthgPositionin ×
Fig. 6-17: Calculation of Incremental Positioning
The formula below applies for absolute positioning:
rtion FactoMultiplica Positiond absolutePreselecte=PositionTarget ×
Fig. 6-18: Calculation of Absolute Positioning
Each change in the factor applies to all subsequent positioning motions. A
positioning motion already in progress is no longer affected by changes in
this factor.
To make a change in the operating mode (Manual/Automatic), the
multiplication factor is preset to a value of 1.000000.
