VLT® 5000/ 5000 FLUX/ 6000 HVAC/
8000 AQUA PROFIBUS
Examples
PCA
Hex 4 corresponds to "transmit parameter value
(array word)" in the RC portion of the PCA. Hex
394 = 916 decimal. The frequency converter
repeats the parameter number sent by the
master (for handshake control).
IND
The frequency converter repeats the subindex sent
by the master (for handshake control).
PVA (high word and low word
The frequency converter repeats the parameter number
sent by the master (for handshake control).
STW and MAV
For an explanation of the Status word and of the
main actual value see example 1.
PCD1
HEX F6 = 246 decimal. The conversion index for
parameter 520 is -2, i.e. the value must be divided by
100. Thus, the present motor current is: 2.46 A
PCD2 to PCD4
Since the PCD in this example are not configured
yet, the frequency converter will fill the individual
PCD with Hex 0000.
NB!:
Please note that modified parameters are
only saved permanently (protected against the
event of a mains failure) in the EEProm of the
frequency converter if parameter 971 is activated after
the parameter modification. This is not done in the
example, i.e. the configuration of the PCD data is
lost after switching the mains current off/on.
