The default connection of the control signals depends on the application macro in
use, which is selected with parameter 9902 APPLIC MACRO. See chapter
Application macros on page 69 for the connection diagrams.
Switch S1 selects voltage (0 [2]…10 V) or current (0 [4]…20 mA) as the signal type
for analog input AI. By default, switch S1 is in the current position.
I
Top position: I (0 [4]…20 mA), default for AI
U
Bottom position: U (0 [2]…10 V)
If DI5 is used as a frequency input, set group 18 FREQ INPUT parameters
accordingly.
