The signal inversion function is useful for example in a situation where PLC sends power
limit to the drive by using analogue inputs. If PLC is unable to communicate to the drive,
the power limit is normally zero. When an inverted signal logic is used, a zero value from
PLC means maximum power limit. This allows you to run the drive, for example, from
the keypad without changing the power limit parameters.
0 = No inversion
1 = Signal inverted
