P1.4.3.1
377
AI1 signal selection “AI1 signal sel”
P1.4.4.1
388
AI2 signal selection “AI2 signal sel”
Connect the AI1/AI2 signal to the analog input of your choice with this parameter. For
more information about the TTF programming method, see chapter 2.
P1.4.3.2
324
Analog input 1 reference filter time “AI1 filter time”
P1.4.4.2
329
Analog input 2 reference filter time “AI2 filter time”
First order filtering is used for analog signals that are used to control e.g. the power
limit. Second order filtering is used for frequency reference filtering.
