Once cell fault(s) occurs, the drive

may not be able to support actual
motor voltage. If the motor voltage
does not decay below the max drive
voltage capability (with the faulted
cell(s)) within the time set by this
parameter, the drive issues a fault.

•
This parameter enables or disables
fast cell bypass. Disabling fast
bypass with mechanical contactors
will still provide manual bypass after
a manual reset.
