Conversion:
The different attributes for each parameter can be
seen in the section on factory settings.
Since a parameter value can only be transferred as a
whole number, a conversion factor must be used to
transfer decimals.
Example:
Parameter 201: minimum frequency, conversion factor
0.1. If parameter 201 is to be set to 10 Hz, a value of
100 must be transferred, since a conversion factor of
0.1 means that the transferred value will be multiplied
by 0.1. A value of 100 will thus be understood as 10.0.
