4.2 Viewing and Modifying Function Codes
The operation panel of the EM15 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.
Diagram 4-2 Operation procedure on the operation panel
Instruction:
We can return to level II menu from Level III menu by pressing "PRG/ESC" 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/ESC", 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 Monitoring Status Parameters
In the stop or running status, you can press "
" on the operation panel to display various status parameters.
Whether parameters are displayed is determined by the binary bits of values converted from the values of
b9-02(Displaying parameters on running status 1), b9-03(Displaying parameters on running status 2), and
b9-04(Displaying parameters on stop status) in the hexadecimal format.
In stop status, there are 16 status parameters you can select to displayed or not, they are: setting frequency, bus
voltage, DI input status, DO output status, analog input AI1 voltage, analog input AI2 voltage, analog input AI3
voltage, count value, length value, PLC running step, load speed, PID setting, PULSE input frequency and three
reserved parameters.
In running state, there are five running status parameters: running frequency, setting frequency, bus voltage, output
voltage and output current. This five parameters are default displaying. The other display parameters includes
output power, output torque, DI input status, DO output status, analog input AI1 voltage, analog input AI2 voltage,
analog input AI3 voltage, count value, length value, linear speed, PID setting, PID feedback, etc. You can set
whether these parameters are displayed or not by setting b9-02 and b9-03.
When the frequency inverter is repowered on again after power failure, the parameters are recorded as before
power failure and displaying.
