If
an inverter which has been

is

be
used, the set values

the parameters
might have been changed according to a
specific
operation. Therefore, it
is
necessary
to
initialize
the
parameter set values before starting the operation. The ten initialize refers
to
the
operation to reset the parameter values
to
the factory-setting values.
The parameter unit can be
used
to
initialize the parameter set values. (Refer
to
page 39
for details of initialization procdure.)
Remember that the following parameters cannot
be
initialized by the parameter clear opera-
tion using the parameter unit. For these parameters, change the parameter set value
to
the
required value after reading the current setting, or reset the parameters
to
the factory-set-
ting by the aU clear operation.
