Sensor-free Vector Control
The 3G3MV Inverters support sensor-free vector control, ensuring
high-torque operation at low motor speeds. The 3G3MV delivers 150% torque
at 1 Hz.
|
|
Full Network Compatibility
The 3G3MV Inverters are compatible with FA networks. The 3G3MV Inverters
support RS-422 and RS-485 communications and allow the mounting of the CompoBus/D Communications Unit to save wiring effort and make it possible
to control the operating conditions of the Inverter.

Easier Application
The frequency adjuster on the Digital Operator provides easy speed
control. The Digital Operator also makes it possible to copy and control
parameters.
|
|
Versatile Control and Protective Functions
The standard models provide energy-saving and PID control functions for
the effective control of pumps and fans. The 3G3MV Inverters incorporate a
high-speed current limit function that suppresses overcurrent tripping and
ensures the smooth operation of the motor. Furthermore, the 3G3MV Inverter
incorporates an inrush current preventive circuit for better protection of
the system.
|
|
Easier Maintenance
The 3G3MV Inverters have easy-to-use cooling fans that can be easily
mounted or dismounted.
|
|
Compact Size to Save Space
The 3G3MV Inverters are of a compact and light construction to save space.
The DIN Track Mounting Bracket makes it possible to easily mount a 3G3MV
Inverter to DIN track. Furthermore, the main and control circuits are
easily wired with screw terminals.

Energy-saving Operation
A 3-phase induction motor will slow down with a decrease in supply voltage
if the load is light. Using these characteristics, the 3G3MV is designed
to estimate the load by detecting supply current to the motor and decrease
supply voltage to the motor automatically to optimize the energy efficiency
of the 3G3MV Inverter. Consequently, the 3G3MV Inverter consumes less
power and saves energy.

|
Supports a Variety of I/O
The 3G3MV Inverter supports analog inputs between 0 and 10 V, 4 to 20mA or
pulse train inputs between 0.1 kHz and 33.0 kHz (set in a parameter).
Furthermore, multi-function signals and pulse train signals for monitoring
purposes are output from the 3G3MV Inverters.
|
|
International Standards
Standards models meet CE and and UL/cUL standards. The 3G3MV Series
includes 3-phase and single-phase 200-V models and 3-phase 400-V models
that are compatible with a wide variety of power supplies around the
world.
