Examples for Operation of PZD Process Data Area
Example 1
The master communicates with the slave via PPO4. From
fig. 12-33 "Re‐
quest Data Frame in PKW Area_from master to slave" on page 196 and fig.
12-50 "Process data PZD3 – PZD 10 values and function code settings" on
page 204 , we need to set status monitoring value corresponding to PZD3 -
PZD6 in parameters of Frequency Converter Fv.
If we need to start frequency converter for forward rotation at 50.00 Hz
(0×1388), and request PZD3 to reflect output current, PZD4 to reflect output
voltage, PZD5 to reflect DC bus voltage, PZD6 to reflect radiator tempera‐
ture, respective function codes are set as: [H0.04]=82; [H0.05]=67. Complete
PPO request and response messages are shown in fig. 12-51 "Example 1 for
PZD process data area_request and response messages of PPO" on page
205 .

es of PPO
In this example, request and response data frame is the message
of frequency converter at stable operation. Actually, at the instant
start-up of the frequency converter, response data frame in PZD
area is “000× 0000 0001 0000 1369 0019” (× means rotation di‐
rection is not certain at the instant of activation).
Example 2
When the converter forward runs at 50 Hz, to stop the converter as parame‐
ter settings, please refer to example 1.
