4.13 How to use inverter serial communication
See the P8 group function for the hardware communication parameter configurati-
on of the communication port. Setting the communication rate and data format to
be consistent with the host computer is the premise for normal communication.
The serial port of KD600 has a built-in MODBUS-RTU slave communication prot-
ocol. The host computer can query or modify the inverter function code, various
running status parameters, and send running commands and operating frequenc-
ies to the inverter through the serial port.

The internal information of function codes, various operating status parameters,
various operating instructions and other information in KD600 is organized in the
way of "register parameter address".

4.14 Password setting
The inverter provides the user password protection function. When P7-49 is set to
non-zero, it is the user password. After returning to the status parameter interface,
the password protection will take effect. At this time, press the PRG key, it will dis

otherwise the panel will display "-----" and the function code cannot be entered.
If you want to cancel the password protection function, you can only enter through
