If
an inverter which has been

before
is to be used, the set values
01
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 t e n 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 a U clear operation.
