Motor doesn’t run after inverter works:
· Inspect if there is balanced three-phase output among U, V, W. If
yes, then motor could be damaged, or mechanically locked.
· If the output is unbalanced or lost, the inverter drive board or the
output module may be damaged, ask for support.
Inverter displays normally when power on, but switch at the
input side trips when running:
· Inspect whether the output side of inverter is short circuit. If yes,
ask for support.
· Inspect whether ground fault exists. If yes, solve it.
· If trip happens occasionally and the distance between motor and
inverter is too far, it is recommended to install output AC reactor.
· Inspect whether the output module is burnt or not. If yes, ask for
support.
