PZD Process Data Area
When the master is sending a request message to the slave , PZD1 and
PZD2 in PZD process data area are respectively corresponding to control
word (CW) and reference frequency (REF) and PZD3 - PZD10 (number de‐
pending on PPO type) are written as 0. When the slave returns a response
message to the master, PZD1 and PZD2 in PZD process data area are re‐
spectively corresponding to status word (SW) and actual output frequency
(ACT), and PZD3-PZD10 are corresponding to status monitoring values
(such as output current, output voltage, AC bus voltage, etc.) set by function
code parameter [H0.04] – [H0.07].
