3.2.31 Conversion of stretch factor (CONVPHD)
3−121
l
EDSVS9332K−EXT EN 4.0
3.2.31.2 Encoder adaptation
The encoder is adapted to the controller using the freely adjustable encoder constants
l C1480 in CONVPHD1
Using this function block, the encoder can be adapted in increments of one (1, 2, 3, 4... 32767) instead
of in increments of
2 0 , 2 1 , 2 3 etc., when using DFIN.
3.2.31.3 Stretch factor setting over 6 decades
The function blocks can be used for fine adjustment of the stretch factor (6 decades).
The stretch factor is set:
l CONVPHD1:
via freely connectable inputs
Tip!
If only the stretch factor is used (in this case the function block is positioned elsewhere in the circuit),
set the encoder constant to 16384 inc/rev. Otherwise the signal will be additionally amplified (small
values) or attenuated (higher values).
When setting negative values in the numerator, the output signal will be inverted.
