Loading Defaults /
Function # 995
Every parameter in the drive has a factory-
set default value that is loaded when the
drive is powered up for the first time.
These default parameters may not be
optimal values for the drive when actually
running, but they will generally allow the
drive to function properly. It is possible to
reload these default parameters with
function # 995 of the PCDU. A reload of
the defaults would generally be done when
the drive is operating erratically, and it is
suspected that one or more parameters
were improperly set.
CAUTION
Use of the LOAD DEFAULTS
function will overwrite EVERY
parameter currently being used
by the drive with the factory-set
default for the parameter. There
is no way to automatically

previous values once this
function is used.
Function # 995 performs the transfer of
data from the default parameter list to the
NVRAM parameter list. The process for
accessing the Load Defaults Function is as
