When system is subject to fault, please read value of function
code [E45] of frequency converter.
Example 1
If the Maximum frequency of the converter is set at 100 Hz, to forward run the
converter ward run at 200 Hz (0x4E20) (exceeds the maximum frequency),
then the PPO request and response messages are shown in fig. 12-48 "Ex‐
ample 1_PPO request and response messages" on page 203 .

In this example, the feedback status word is 0x0180, bit 7 – 9 of
status word is 011 (PZD area set frequency exceeds limit).
Example 2
The converter is first forward run at 50 Hz (0x1388), the hardware circuit of
communication is then disconnected, then the PPO request and response
messages are shown in fig. 12-49 "Example 2_PPO request and response
messages" on page 203 .
