This setting allows only the user-selected parameters (up to 32) to be displayed
or changed. Select the desired parameters as "User Parameters" in parameters
A2-01 through A2-32.
This setting allows the parameters required to start the Inverter (about 25) to be
displayed or changed.
This setting allows the commonly used parameters to be displayed or changed.
This setting allows all parameters to be displayed or changed.
