Operation Only This setting allows operation mode and initialize mode to be displayed or
changed. Use this setting to prevent parameter settings from being changed.
1
User Level
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.
2
Quick-start
This setting allows the parameters required to start the Inverter (about 25) to be
displayed or changed.
3
Basic
This setting allows the commonly used parameters to be displayed or changed.
4
Advanced
This setting allows all parameters to be displayed or changed.
S
Setting the Control Mode
Use parameter A1-02 to select one of the four control modes. This parameter is not initialized by the
initialize operation and it cannot be changed during operation.
