The frequency reference value is transmitted to the
frequency converter in the form of a 16-bit word. The
value is transmitted as a whole number (0-32767).
16384 (4000 Hex) corresponds to 100%. (Negative
figures are formed by means of 2's complement.)
The bus reference has the following format:
Parameter 203 = "0"
