2.4.33.2 Conversion
The analog input signal at FEVAN1−IN is converted into the corresponding value of the target using
C1093 (numerator) and C1094 (denominator). At the same time, it is adapted to the suitable data
format.
Tip!
Make sure that the input signal is processed unscaled (100% correspond to 16384) when
determining the values for C1093 and C1094.
For the decimal positions of the target code, always multiply the value to be transmitted with the
factor 10000.

Example 1
A signal of 100 % is to result in a maximum current I
max
(C0022) of 10 A.
l The input signal of 100 % results in an input value of 16384.
l The value to be transmitted (C1090) must be 100000 (10 A
× 10000).
l Enter these values in C1093 (numerator) and C1094 (denominator):

Example 2
A signal of 10 % ... 50 % is to result in an acceleration time T
ir
(C0012) of 1.5 s ... 7.5 s.
l The input signal of 50 % results in an input value of 8192.
l The value to be transmitted (C1090) must be 75000 (7.5 s × 10000).
l Enter these values in C1093 (numerator) and C1094 (denominator):
