Parameter setting

1 When there is no password protection

 

 

1) Press the function key (MO) during normal operation in one second, the secondary display window will display Pn-00; the current parameter value of the main display window, you can use the ↑ key to cycle through the display until the parameter you want to modify Pn-XX

2) When the parameter “Pn-XX” is displayed in the secondary window, press the enter key (En) to enter the parameter setting state, and the parameter displayed in the main window is blinking;

3) To modify the value, make sure that the current modified digit is the blinking digit. If it is not, press the function key (MO) to change the position of the blinking digit in turn from right to left. Different parameters display different digits. Use the ↑ key to change

 

 the value, after setting the parameter, press the enter key (En) to jump out of the setting of the parameter Pn-XX,

4) Press (MO) to return to working state.

5) When entering any state in the setting, if you press the clear key (CL.), it will not save and exit, but the parameters just modified are temporarily effective before the power is turned off (except the serial port baud rate), and will be re-powered. Restore the previous setting value. This function can be used to view parameters.

1.1 Enter the speed setting interface

1) Press the function key (MO) for more than 2 seconds during normal operation, the secondary window will display Sn-00, and the main window will display the current parameter value. The steps for switching, modifying, and saving are the same as the previous steps.

  1. When there is password protection

Press the function key and enter the corresponding setting according to the above method, the main window will display “Pn-CO.” and enter the password input state. At this time, the window displays 0000 and the lowest digit flashes. Refer to the above operation, enter the correct password through the ↑↓ key and the function key (MO), press the OK key (En) to confirm, and the program enters the parameter setting state. If the password is entered incorrectly or the clear key (CL.) is pressed, the program returns to the working state.

Restore factory settings

In the working state, press the ↑ key and the EN key at the same time, and the buzzer will beep for more than 5 seconds. Then it will restore the factory settings.
