Control Word According To Fieldbus Profile Standard - Danfoss VLT FCM Series Manual

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.
Addressing by unit ID
2. Process-bytes
The process byte block is divided into two blocks each
of 16 bits, which always come in the sequence stated.

Control word according to Fieldbus Profile Standard

(parameter 512 = Fieldbus Profile) The control word
is used for transmitting commands from a master
(e.g. a PC) to a slave (FC motor).

The unit ID is printed on the label on the plastic
cover under the lid of the electronics box. The three
groups of unit ID each with three digits must be
converted to Hex. The desired address is added as
the last byte. The frame is sent to the bus address
