How to Set Base Frequency to 60Hz on VFD?

This blog will guide you through configuring the base frequency to 60Hz on ATO's EM15 Variable Frequency Drive (VFD). This adjustment is crucial for tailoring the VFD's operation to meet specific industrial requirements, ensuring optimal performance. Follow these step-by-step instructions to customize the VFD according to your specific requirements.

Programming

Step 1. Enter Programming Mode

Press the PRG key on the VFD to enter programming mode.
Select parameter group F0 and press Enter to access F0 group parameters.

Step 2. Parameter F003

Select parameter 03 and modify it to 1 (for 60Hz operation). Press Enter to confirm.

Step 3. Parameter F010

Select parameter 10 to set the maximum VFD frequency.
Set it to 60Hz and press Enter to save.

Step 4. Parameter F012

Select parameter 12 to define the frequency upper limit.
Set it to 60Hz and confirm the changes before exiting.

Step 5. Parameter F014

Choose parameter 14 to set the frequency lower limit.
Set it to 0 and save the changes.

Step 6. Parameter F008

Select parameter 08 to input the preset frequency.
Set it to 60Hz and press Enter to save and exit.

Step 7. Exit Programming Mode

Press the ESC key repeatedly until you exit the programming mode and return to the VFD's operating mode.

Testing and Operation

Proceed by pressing the green Run button on the control panel to start the device and see if it functions as expected. As you can see, the frequency on the control panel display is gradually increasing until it reaches the maximum frequency of 60Hz. This indicates that the device is operating according to the programmed settings.

Setting base frequency to 60hz

To stop the VFD, press the red Stop button. You will notice that the frequency gradually decreases to 0 and then immediately jumps back to 60Hz, which is continuously flashing. This demonstrates that even if the power is removed, the VFD retains the preset frequency value.

By following these comprehensive steps, you've successfully configured the Variable Frequency Drive to operate at a base frequency of 60Hz.
