P2.4.5.5. AI3 signal inversion ID151
P2.4.6.5 AI4 signal inversion ID162
The signal inversion function is useful in a situation when e.g. the PLC is sending power
limit to the drive using fieldbus. If the PLC is unable to communicate with the drive the
power limit from fieldbus to the drive would be zero. Using an inverted signal logic zero
value from PLC would mean maximum power limit. When inversion is needed for the
process data signal fieldbus values need to be written to Analogue input monitoring
signals. See parameter P2.4.5.1 AI3 Signal selection for details.
0 = No inversion
1 = Signal inverted
