Changing the function of the terminals
The function of the terminals marked in color in the two figures above, can be set.
In order that you do not have to successively change terminal for terminal, several terminals
can be jointly set using default settings ("p0015 Macro drive unit").
The terminal settings made in the factory described above correspond to the following
default settings:
● Default setting 12 (p0015 = 12): "Standard I/O with analog setpoint"
● Default setting 7 (p0015 = 7): "Fieldbus with data set switchover"
Further default settings can be found in the Operating Instructions, see also: Manuals for
your inverter (Page 31).
