In the Third level menu state, if the parameter is without flash bit, it indicates that the
functioncodecouldn’tbemodified,itmaybecausedbythefollowingreasons:
1) The function code is non-modifiable parameter, such as actual monitoring parameter
and run recording parameter and so on.
2) The function code is in the process of running, it couldn’t be modified and only
could be modified after stop.
The operation panel can do a lot of operations, such as: set the parameters, reset the
faults, auto-learn the motor’s parameters, set the password, display the running state and
so on, we would introduce all kinds of operation method and procedure in the following.
4.4 Checking Method of State Parameter
The user could select the stop normal monitoring variable by setting F9.01 and select the
running normal monitoring variable by setting F9.02. When the frequency inverter is
powered after the power failure, the shown parameter is defaulted as the selected
parameterbeforepowerfailure.
In the stop or run state, the
 following 6 variables could be shown in cycle by the shift
key >>/SHIFT : run frequency (Hz light is flash), setting frequency (Hz light is on), busbar
