2.3.2.5 AI1 signal inversion
2.3.3.5 AI2 signal inversion
Signal inversion function is useful in situation when e.g. PLC is sending power limit to
the drive by using analogue inputs, if PLC is unable to communicate to the drive power
limit would be normally zero, by using inverted signal logic zero value from PLC would
mean maximum power limit thus allowing drive running e.g. from keypad without
changing power limit function parameters.
0 = No inversion
1 = Signal inverted
