Fig. 4-2 Operation Procedures for 3-level Menu
Note: When operating on the third level menu, press the PRG or ENTER, it can return to the second
level menu. The difference is: When pressing ENTER, the parameters will be saved and the screen
will return to second level menu and then shift to the next function code. When pressing PRG, it will
return to second level menu without saving the parameters, and remain in the position of the current
function code.
In third level menu, if the parameter has no flash bit, it means the function code cannot be changed
and the possible reasons are:
1) This parameter of the function code cannot be changed, such as the actually detected
parameter and running record parameter.
2) This function code cannot be changed in running status and can only be changed when the
inverter is stopped;
3) This parameter value is the actually measured value and cannot be modified.
2: Operating method for displaying Status Parameters:
When MD300A inverter is in the stop or running status, several status parameters of the inverter can
be displayed on the LED. Press the shift key
》 the stop or running status parameters can be
displayed in sequence.MD300A inverter has seven running status parameters to be displayed in
sequence by pressing the key
》, namely, running frequency 》setting frequency 》bus voltage 》
output voltage 》output current 》terminal status 》panel potentiometer voltage 》analog input AI.
