323 AI1 SIGNAL INVERSION 3457 (2.2.7, 2.2.19, 2.2.2.6)
If this parameter = 0, no inversion of analogue input signal takes place
NOTE!
In application 3, AI1 is place B frequency reference if parameter ID131= 0 (default).
Fig. 42: AI1 no signal inversion
If this parameter = 1 inversion of analogue input signal takes place.
Max. AI1 signal = minimum frequency ref.
Min. AI1 signal = maximum frequency ref.
