PZD is the process data. The master station of PZD can send instructions to the frequency inverter
periodically and read the current status of the frequency inverter periodically. Each PZD can select
configuration and select the parameters to be interacted between the master station and the slave
station. PZD1 and PZD2 are fixed configuration and cannot be modified. The configuration of PZD3
~ PZD12 can be changed according to the specific needs of users. The interactive data is shown in
table 3.5
