Description
V/Hz mode only: If the
current exceeds 180% of
induction stack rated
current for a period of 1
second, the drive will trip.
This is caused by shock
loads

has fallen below 17V
The motor is drawing too
much current (>100%) at
zero output frequency

 Excessive loading
 FIXED BOOST and/or AUTO BOOST set too high
(refer to FLUXING menu at level 3)
