New Features
New features have been added to 3G3MV-Series models with 5.5-kW and 7.5-kW ca-
pacities (i.e., the 3G3MV-A2055/A2075/ A4055/A4075). These features are outlined
below and explained in detail in
Chapter 6
.

New Features for 3G3MV-A2055/A2075/A4055/A4075 Only
D
Enclosure Rating: Closed Wall-mounting Conforming to IP20/NEMA1
The 5.5-kW and 7.5-kW Inverters have closed wall-mounting specifications that conform to
IP20/NEMA1, so they can operate in an ambient temperature range of –10 to 40
°
C.
Note
To operate this Inverter within an ambient temperature range of –10 to 50
°
C, remove the top and
bottom covers to convert it to a panel-mounting model (IP00).
D
Default Settings Changed for V/f Patterns (Parameters: n011 to n017)
For 5.5-kW and 7.5-kW Inverters, two of the default settings have been changed. The default settings
for the middle output frequency voltage (VC) (n015) and the minimum output frequency voltage (VMIN
(n017) have both been changed to 10 V for 200-V-class models and to 20 V for 400-V-class models.
D
Inverter Overheating Warning Input
(Parameters: n050 to n056; Fault Display: oH3)
An Inverter overheating warning input has been added as a new function that can be set for multi-func-
tion inputs 1 to 7 (n050 to n056). When this warning is input, an oH3 fault (nonfatal error) will be dis-
played. This input can be used for functions such as thermal contact connections for peripheral over-
heating detection.
D
Frequency Reference Loss Detection (Parameter: n064)
When the frequency is referenced using analog frequency reference inputs (0 to 10 V/4 to 20 mA/0 to 20
mA), this function detects sudden changes in analog inputs as errors (disconnection, short circuit,
breakdown, etc.) and outputs the frequency reference loss output that is set in multi-function outputs 1
to 3 (n057 to n059). After the change is detected, operation continues at 80% of the frequency reference
prior to the change.
D
Accumulated Operating Time (Monitor: U-13; Parameters: n087, n088)
This function calculates and stores in memory the Inverter’s accumulated power-ON time or RUN time.
Use it for checking and determining the maintenance schedule.
D
Speed Search Adjustment (Parameters: n101, n102)
A function has been added for adjusting the speed search. (The speed search is a function for detecting
and smoothly controlling the speed of a free running motor.) The speed search operating time and
search level can be adjusted.
D
Input Open-phase Detection
(Parameters: n166, n167; Fault Display: PF)
This function detects the Inverter’s input power supply open phase. Open phases are detected through
main circuit voltage fluctuations, so this function can also be used for detecting abnormal voltage fluc-
tuations in the input power supply voltage.
