    What should be checked if an Altivar 61 or 71 display is showing NLP?

    What should be checked if an Altivar 61 or 71 display is showing NLP?

    Product Line:
    ATV61/71 drives


    Drive displays 'NLP'

    NLP indicates that no line power is present on the L1, L2 & L3 input terminals of the drive controller.

    Check voltage at the L1, L2 & L3 terminals.
    Check for open circuits on line contactors, circuit breakers, disconnect switches, or fuses.

    If NLP state does not change with correct voltage present on L1, L2, & L3, remove the control board and check for loose connections of ribbon cables inside the drive.
    WARNING: This step should be performed while the drive is powered down, and proper personal protective equipment should be worn. 

    For example: In an ATV71HC25N4 a customer found a loose X3 connector from the control board to the board behind and above the control board. This connector was on a ribbon cable that was about 1 inch by 1 inch. Drive ran OK after this was reseated.
