5.1.4  Operation modes 
  The operation modes of the analog input characteristic enable application-related scal-
in
g
 as a supplement to the characteristic points stated. One of the four linear types o
f
characteristic is selected for adaptation of the si
g
nal for the analo
g
 input si
g
nal via the
parameter 
Operation mode 562. 
If the characteristic points are not suited for the type of characteristic selected, the
characteristic points are corrected internally. 
  Operation mode  Function 
 1 - bipolar  The analog input signal is mapped onto the reference 
figure according to the characteristic points (X1/Y1) 
and (X2/Y2). 
 11 - unipolar  With a negative parameter value of the characteristic 
points X1 or X2, they are mapped to the reference 
value zero. 
 21 - unipolar 
2…10 V / 4…20 mA 
If the characteristic points X1 or X2 have been set 
with a negative parameter figure or smaller than 0%, 
the input characteristic is mapped to the reference 
value 20%. 
 101 - bipolar absolute value  Negative parameter values of the characteristic points 
Y1 or Y2 are mapped as a positive reference value in 
the characteristic. 
  Further information on the operation modes stated in the table can be found in the
following chapter “Examples“.
