Hi,
I have a Schneider VFD - ATV320, 1.5kW for a Horizontal motion in which when it is running it shows nLP intermittently in between. First DBR connected was wrong then we replaced with correct one which resolved braking fault problem.
But this nLP is not going at all and it is other VFDs(used for other motions on same machine) as well.
We checked input power by multi-meter and it is ok i.e. 400V - 3Ph during standstill and running condition.
