What is OSF in the ATV18?

Line over voltage fault.  Overvoltage in steady state or acceleration.
Check line voltage. ATV18???M2, 1-phase: = 240 V +10%
ATV18???M2, 3-phase: =230 V +10%
ATV18???N4: = 460 V +10%
Compare the line voltage as read with a true RMS meter with the mains voltage reading on the drive display.
This fault can be caused if there are high harmonics on the inputs.
Consider the installation of line inductors.
