Issue:
Why PHF is displayed on ATV312/ATV31 drives?
Product Line:
Altivar 312 - ATV312
Altivar 31 - ATV31
Environment:
All
Cause:
Loss of input voltage on LI1, LI2 or LI3
Resolution:
- Check for phase loss or phase imbalance.
- Check the Line voltage power, input connections and or fuses.
- Check to see if you use single phase on the input on the drive.
- Reset the drive.
- Disable the detection by setting input phase loss to "No." (IPL parameter is found in the FLt menu and can be changed if the drive is not running) Then run and check current on each phase to be sure it is balanced (for 3 phase power).
- If single phase input voltage, set IPL to NO
