9.5 Special Instructions
1. The host machine can read but cannot change the inverter parameters: F08 group (asynchronous
motor), F17 group (SCI communication), keep the parameters.
2. The host machine communication cannot change F01.00 (user password), but you can write F01.00
verify the user password, the host machine gets the function parameters of the inverter, after the
change, by writing invalid the password to F01.00 and make the host machine no permission to
change the function parameters of the inverter.
3. Various multi-function input terminal function settings will lead to the same function, through the
MODBUS protocol to modify the multi-function terminal function to avoid this situation.
