31-KSEL Data set selector
The data set selector determines the control factors for data changeover.
Possible control factors for data changeover:
31-KSEL Function Example of application
0 Data set changeover inactive, Standard, factory setting
data set 1 remains
1 Changeover to 2nd data set Heavy load start-up
if: 12-F > 26-FF6
2 Changing over data sets Varying operation
with S2IND from 2 motors to 1 inverter
3 Changing over to 2nd data set Drive with rotation direction
with counter-clockwise
(STL active) dependent load
Two data sets with following parameters are available.
