What causes a 4-20mA loss (LFF) on an ATV312 drive?
ATV312 4-20mA loss, LFF error code on display
Product Line:
Altivar Machine 312
Resolution:
This will happen if the LFF is programmed to a function other than ignore (no).
If it is programmed to a function other than no, then the drive is designed to have a value of 4 mA minimum (unless CRL3 is changed to 0 instead of 4A) on AI3 input.
