Process Word - Danfoss VLT 8000 AQUA series Operating Instructions Manual

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.

Process word

The process word block is divided into two blocks each
of 16 bits, which always come in the sequence stated.
