Tap "Run-parameter" after entering the correct password;
Step 3
Set the "Limit Power (%)" parameter by tapping the pop-up keypad;
Step 4
Tap "Enter" to confirm setting.
Step 5
Parameters related to power limitation (P-rise rate (%/s) and P-decline rate
(%/s)) are also included in the running parameter setting sub-menu and can be
set accordingly.
