Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
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 before execute initialization.
For details on parameter initialization, refer to 5-1-2 Parameter Initialization on page 5-5.
Precautions for Correct Use
• The parameters Total RUN Time Monitor (d016), Total Power ON Time Monitor (d017), and
Initialization Data Selection (b085) will not be initialized.
When you set 00 to Inverter Mode Selection (b171), Heavy load/Light Load Selection
(b049) will not be initialized. Setting any other value than 00 will initialize it.
• The inverter does not display the initialization-related parameters (b084, b094, b180)
depending on the Display Selection (b037) setting. If they are not displayed, change b037 to
00 (Complete display).
• When the Soft Lock Selection (b031) is set to prohibit changes of the initialization-related
parameters (b084, b094, b180), the initialization cannot be executed. Change the Soft Lock
Selection (b031) to enable the initialization.
• For details on Soft Lock Selection, refer to 7-6-1 Soft Lock Function (SFT) on page 7-54.
• Remember that you will not be able to revert to the previous settings once you press the
Enter key to execute parameter initialization, with the Initialization Execution (b180) set to 01.
The following figure shows the steps of 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.
Regardless of the display mode of the Digital Operator, if you press (Mode key) for 1 second or
more, the data of Output Frequency Monitor (d001) is displayed. However, the Digital Operator contin-
ues to display the function mode and extended function mode in sequence as the normal operation if
you press the Mode key for less than 1 second.
