High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
The 3G3RX-V1 Series Inverter contributes to the reduction of man-hours in all phases of
inverter-related work: from wiring, parameter setting, operation, through to maintenance.
 Removable Digital Operator as standard equipment
This inverter has a removable Digital Operator as standard equipment.
By connecting the optional special cable, it is possible to operate the Digital Operator at hand or
install it to the front face of the control panel. This is convenient during setup or maintenance
operation.
The operability of the keys and the method to initialize parameters were changed to the same as
those for the 3G3MX2 Series.
 Addition of the initial screen automatic return function
The inverter newly has the “initial screen automatic return function” which automatically switches the
screen to the initial screen if the Digital Operator is not operated for 10 minutes.
 5-line LCD Digital Operator
This inverter supports the newly released LCD Digital Operator 3G3AX-OP05 with the 5-line display
capability. The LCD Digital Operator can display four monitor functions or parameter settings in the
selected language (currently English only), which effectively improves the readability of the device
status and other information.
In addition, the LCD Digital Operator can store up to four sets of inverter parameter setting data, or a
single set of inverter parameter setting data and a single DriveProgramming program in its internal
memory. This saves time when you set the same parameter or write the same program to more than
one inverter.
 Removable control terminal block
The removable control circuit terminal block enables you to replace an Unit with wiring connected,
which facilitates the maintenance and inspection of the inverter.
 Emergency shutoff function
This function enables to shut off output by the hardware without the software, which can provide
more reliable emergency shutoff operation.
 Modbus communication function as standard
The inverter has the RS485 communications circuit and the Modbus communication protocol as
standard.
You can use Modbus communication to control and monitor the inverter status, or read and write
various parameter settings.
 Change of default parameter setting
The default parameter setting of the conventional 3G3RX Series Inverter were reviewed and were
changed according to the user’s usage. Some functions are enabled by default for reducing the
workload of the user.
The default parameter setting changed in the 3G3RX-V1 Series are shown in Section 4 Parameter
List. Check if these are appropriate for your application.
