5.2.2 Changing via LCV-USB-VS
In the advanced mode, the software offers tabs for configuration. The filter frequencies can be adjus-
ted in configuration block STATOR_OPERATION.
5.2.3 Changing via Self-programmed (own) Software
The adjustment for channel A is stored in bytes 13 and 14 of the configuration block “STATOR_OPE-
RATION”. The value for channel B is stored in bytes 15 and 16. Each byte represents a 16-bit value
and corresponds to the cutoff-frequency according following chart:
Please consider that currently adjusted cutoff-frequency will be active after rebooting, only.
For further information regarding programming with own software we refer to document 090110,
Lorenzprotocol “A flexible command set for digital sensors and interfaces”.
