RUN:
OFF indicates that the frequency inverter is in the stop state and ON indicates that the frequency
inverter is in the running state.
LOCAL:
It indicates whether the frequency inverter is operated by operation keypad, terminals or remoter
(communication). OFF indicates keypad operation control state; ON indicates terminals operation control
state; Blinking indicates remote operation control state.
DIR:
It is Forward/Reversal indicator, ON indicates forward rotation.
TRIP:
Tunning/ Torque Control/Fault indicator
When the indicator is ON, it indicates torque control mode. When the indicator is blinking slowly, it
indicates the auto-tuning state. When the indicator is blinking quickly, it indicates the fault state.

4.2 Viewing and Modifying Function Codes
The operation panel of the EM11 adopts three-level menu.
The three-level menu consists of function code group (Level I), function code (Level II), and function code
setting value (level III), as shown in the following figure.

Instruction:
We can return to level II menu from Level III menu by pressing PRG or ENTER.
The difference between them is:
After you press ENTER, the system saves the parameter setting first, and then goes back to Level II menu
and shifts to the next function code.
After you press PRG, the system does not save the parameter setting, but directly returns to Level II menu
and remains at the present function code.
Under the Level III state, if there is no blinking digit of this parameter, then it indicates that the parameter
can not to be modified. The possible reasons are:
1.
This function code is a non-modifiable parameter, such as the actual testing parameters, operation
records, etc.
2.
This function code cannot be modified under the running state, but can modify after stopping.
4.3 Parameter Display Mode
The establishment of parameter display is to make the user conveniently to check the parameters in
different permutation modes. Three kinds of parameter display modes are offered.
