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.
E
xample:
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.
