Displays alarm code such as E01 on data display.

You can initialize the changed parameters and also clear the fault monitor data.
As a measure to prevent inadvertent parameter initialization, the inverter is designed to force the user
to set several parameters to execute initialization.
The following figure shows the steps of complete parameter initialization.
To initialize all the parameters, set the Initialization Target Setting (b094) to 00 (All data).
To initialize the fault monitor and DriveProgramming data in addition to the parameter data, set the Ini-
tialization Selection (b084) to 04.
Set the Initialization Execution (b180) to 01 (Execute initialization) to execute parameter initialization.
For details on parameter initialization, refer to 5-1 Parameter Display and Parameter Initialization on
page 5-3.
