Key Name Function
STOP/RESET Stop/Reset
Stop the frequency inverter when it is in the running state and perform the
reset operation when it is in the fault state. The functions of this key are
restricted by b9-00.
MF.K Multi-function Perform function switchover according to the setting of b9-01
4.2 Viewing and Modifying Function Codes
The operation panel of the EM12 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" 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 Monitoring Status Parameters
In the stop or running state, you can press “ ” on the operation panel to display status parameters. Whether
parameters are displayed is determined by the binary bits of values converted from the values of b9-02(running
parameter 1), b9-03(running parameter 2), and b9-04(stopping parameter) in the hexadecimal format.
In stop state, 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 state parameters: running frequency, setting frequency, bus voltage, output
voltage and output current. This five parameters are default displaying. The other display parameter 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 by setting b9-02 and b9-03.
