This guide shows how to use the VFD keypad to find and change a parameter.

 

You may be asked by PwnCNC support or one of our setup guides to change a VFD setting like this:

P0.0.03 = 2

 

In that example:

• P0.0.03 is the parameter code you need to find.
• 2 is the value you need to enter.

Step 1: Turn on the VFD

Power on your VFD and wait for the display to finish starting up.

Step 2: Enter Programming Mode

Press the MODE button.

The display should show a parameter code, such as:

P0.0.00

Step 3: Move to the Parameter Code

Use the keypad buttons to move to the parameter code you need.

• Use the up and down arrow buttons to change the selected number.
• Use the >> button to move to the next digit.

For example, if your instructions say:

P0.0.03 = 2

Use the keypad until the display shows:

P0.0.03

Step 4: Open the Parameter

Press ENTER.

The display will now show the current value saved for that parameter.

Step 5: Change the Value

Use the up and down arrow buttons to change the value.

For example, if your instructions say:

P0.0.03 = 2

Change the displayed value to:

2

Step 6: Save the Value

Press ENTER to save the new value.

Step 7: Exit Programming Mode

Press MODE to back out of the menu.

You can now repeat these same steps for any other VFD parameters listed in your setup instructions.

Quick Example

To enter this setting:

P0.0.04 = 9

1. Press MODE.
2. Navigate to P0.0.04.
3. Press ENTER.
4. Change the value to 9.
5. Press ENTER to save.
6. Press MODE to exit.

Important Notes

• Only change the parameters listed in your PwnCNC setup instructions.
• Changing random VFD settings can prevent your spindle from running correctly.
• If a value does not appear to save, press ENTER again and confirm the display returns to the parameter code before exiting.
