Examples for operation of PZD process data area
Example 1
The master communicates with the slave via PPO4. We need set monitoring pa-
rameters corresponding to PZD3 - PZD6, see fig. 13-5 "PPO type" on page 204.
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 module temperature,
respective parameters are set as: [H0.10]=5, [H0.11]=4, [H0.12]=7, [H0.13]=16.
Complete PPO request and response messages are shown in table below.

The higher byte of the status word is the latest error code (0x00
means no error).
Example 2
When the frequency converter forward runs at 50 Hz, to stop the frequency con-
verter as parameter settings, please refer to example 1.
