There has been a great demand for inverters that provide easier motor speed control. OMRON's simple, compact 3G3JV Series meets the demand. The 3G3JV Inverters provide versatile functions and ensure powerful performance. The front panel of the 3G3JV Inverter has a frequency adjuster that makes it possible to start the motor and easily control the motor speed. The 3G3JV Inverters are easy to mount and operate and support a wide range of applications for efficient motor control.

The frequency adjuster on the front panel makes it possible to easily adjust the speed of the motor. The Inverter can be operated immediately after the power is turned ON.

The 3G3JV Inverter performs versatile speed control, such as multi-step speed control up to a maximum of nine steps, acceleration and deceleration (UP/DOWN) control, and jog operations. Furthermore, the 3G3JV Inverter provides a variety of useful functions, including slip compensation, overtorque detection, and speed search functions.

The cooling fan can be easily mounted or dismounted. The cooling fan can also be turned on only when the 3G3JV Inverter is in operation, prolonging the life of the fan.

The 3G3JV Inverters are compact and space-saving to mount easily into a panel.

The 3G3JV Inverter incorporates main circuit terminals arranged in two rows on the top and bottom of the housing, making it possible to mount the 3G3JV Inverter like a contactor. The optional DIN Track Mounting Bracket makes it possible to easily mount a 3G3JV Inverter to a DIN track.

The 3G3JV Inverter supports a variety of I/O, such as analog inputs between 0 and 10V, 4 to 20 mA, or 0 to 20 mA, multifunction I/O, and analog monitor outputs. Multi-function inputs can set to either PNP or NPN, providing flexibility in input signals.

Conventional Systems

Relay contact welding occurs, which may put the system and operators in danger. Furthermore, the life of the system is comparatively short.

The system employs a gearbox for speed control, the designing and adjustment of which require time and labor.

To ensure the safety of the system, the system needs peripheral safety devices, the wiring of which requires time and labor.

The motor always rotates at top speed, consuming a high amount of power.

A strong shock is produced when the motor is driven, which may cause loads to shift, deteriorate the quality of products, or put the system and operators in danger.

3G3JV Inverter Solutions

A 3G3JV Inverter has no mechanical relay contacts and thus allows a safe, long-life system operation.

A 3G3JV Inverter performs versatile speed control, such as multi-step speed control for up to nine steps, acceleration and deceleration (UP/DOWN) control, and jog operations.

A 3G3JV Inverter provides a variety of protective functions, such as a highspeed current limit, ground fault protection, and undervoltage protection.

A 3G3JV Inverter drives the motor at flexible speeds within the rated speed range of the motor, thus reducing motor power consumption.

A 3G3JV Inverter provides soft-start and soft-stop functions, preventing loads from shifting and deterioration of product quality, while ensuring the safety of the system.

A 3G3JV Inverter provides soft-start and soft-stop functions to prevent loads from shifting. Furthermore, a 3G3JV Inverter performs flexible speed control of the conveyor up to nine steps.

A 3G3JV Inverter performs flexible speed control of a compact agitator or separator.

Conventional Systems

A strong shock results at the moment the motor is driven, which may cause load shifting, deteriorates the quality of products, or puts the system and operators in danger.

The capacity of the motor is small. Therefore, the rotation speed of the motor will drop if a speed reducer is used for the maintenance of the torque.

The rotation of the motor fluctuates. Failures in the motor are not detected

by the host controller. The types of available motors are

limited.

3G3JV Inverter Solutions

A 3G3JV Inverter provides soft-start and soft-stop functions, preventing loads from shifting and deterioration of product quality while ensuring the safety of the system.

The 3G3JV Inverters are available up to a maximum motor capacity of 3.7 kW and ensure smooth rotation speed and torque in the motor.

A three-phase motor has less speed fluctuation compared with a singlephase motor, ensuring the safe operation of the system.

A 3G3JV Inverter can report errors in contact outputs or data to a host controller, such as a Programmable Controller.

A wide range of motors is available.

3G3JV Inverter

A 3G3JV Inverter provides optimum control of fan speed according to the room temperature. The 3G3JV Inverter has no mechanical relay contacts, ensuring the safety and reliability of the system compared with the ON/OFF control of contactors. Optimum control of fan speed also saves energy.

A 3G3JV Inverter provides multi-step speed control to open and close an electric shutter safely and efficiently. The shutter opens quickly at a high speed, but closes at a medium-range speed while the system checks the safety of the operation and decelerates to low speed before it is fully closed to prevent people from being caught by the shutter.

Acceleration/Deceleration Time Settings (n16 to n19)

The acceleration time is the time required to go from 0% to 100% of the maximum frequency and the deceleration time is the time required to go from 100% to 0% of the maximum frequency. The actual acceleration or deceleration time is obtained from the following formula.

Acceleration/Deceleration time = (Acceleration/Deceleration time set value) × (Frequency reference value) ÷ (Max. frequency)

2. To set the parameter according to the characteristics of the motor, confirm the thermal time constant with the motor manufacturer and set the parameter with some margin. In other words, set the value a little shorter than the thermal time constant.

3. To detect motor overloading more quickly, reduce the set value, provided that it does not cause any application problems.
