Regarding the parameter initialization (data initialization by setting Initialization Selection (b084) to 02
to 04), the parameters not to be initialized have been changed. In the table below, “Yes” indicates those
not to be initialized, and “-” indicates those to be initialized.
In the 3G3MX2-EV2 Series Inverter, the following parameters, which are not to be initialized in
the 3G3MX2-E Series Inverter, will also be initialized.
•
Initialization Target Setting (b094)
The default data will be 00 (All data (Complete initialization)).
Whenever initializing parameters, set and execute Initialization Target Setting (b094).
Refer to 5-1-2 Parameter Initialization on page 5-5 for information on the parameter initialization.
•
O Adjustment (C081), OI Adjustment (C082), Thermistor Adjustment (C085)
The default data will be 100.0%, and the adjusted results will be initialized. Adjust them as necessary.
Refer to 7-3-4 Analog Input Adjustment on page 7-25 for information on the O adjustment and the OI
adjustment.
•
Position Data at Power Off (P082)
The default data will be 0. Perform homing etc. to readjust the position.
Refer to 6-7-4 Origin Search Function, Current Position Preset, Position Data Storage at Power Shut-
off on page 6-40 for information on the position data at power off.
Although Heavy load/Light Load Selection (b049) is not to be initialized by parameter initialization
(Initialization Selection (b084)), by setting Inverter Mode Selection (b171) to 01 to 03, it will be initialized
as with the 3G3MX2-E Series Inverter.
If the Free V/f Frequency 7 (b112) is set to less than 30 Hz, the output may become unstable. For this
reason, the 3G3MX2-EV2 Series Inverter does not start operating even when it receives the RUN com-
mand. The RUN indicator flashes.
Refer to 5-2-1 Control Method (V/f Characteristics) on page 5-8 for free V/f.
