5.6 PZD Data
The PZD data enables the master to modify and read AC drive data in real time and
perform periodic data exchange. The data communication addresses are directly
configured by the AC drive. The specific functions are as follows:
● Setting the AC drive control command and target frequency in real time
● Reading the current state and running frequency of the AC drive in real time
● Exchanging function parameter and monitoring parameter data between the AC
drive and PROFINET master in real time
By default, the written PZD1 and PZD2 are mapped to U3‑17 and U3‑16, respectively.
If a command or frequency fails to be written into the AC drive but PZD3 to PZD12 can
be written and F0‑02 and F0‑03 are set to 2 and 9 respectively, check whether FE‑00
and FE‑01 are set to U3‑17 and U3‑16 respectively. If not, manually correct the values
of FE‑00 and FE‑01. The read PZD1 and PZD2 are mapped to U0‑68 and U0‑69
respectively. If a state or running frequency fails to be read while PZD3 to PZD12 can
be read, check whether FE‑20 and FE‑21 are set to U0‑68 and U0‑69 respectively. If
not, manually correct the values of FE‑20 and FE‑21.
