BONFIGLIOLI Vectron ACTIVE CUBE - Frequency Conversion PDP-Word to Internal Representation

8.4 Frequency conversion PDP-Word to internal representation
If the frequency inverter is equipped with a PROFINET module CM-PROFINET or an
extension module with Systembus, the Convert PDP/internal function will be availa-
ble
. It converts frequency values with Profibus representation to frequency values
with device-internal representation and vice versa, see Chapter
11.3.3 “Reference
value/actual value”.

The function uses its own reference value Convert Reference 1374 for data con-
version. The advantage of this function is the fact that the “Word” data type is used
for frequency values instead of the “Long” data type.
