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 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. This catalog provides information for the selection of models, but does not provide operational precautions. For information on the operation of the 3G3JV Inverters and operational precautions, be sure to read the operation manual. 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 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 Inverters are compact and space-saving to mount easily into a panel. 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. Actual Size Three-phase 100 W at 200 V 68 x 128 x 78.5 mm (W x H x D) Standard models meet CE and UL/cUL standards. C 2 3 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 Breaker adjustment of which require time and labor. To ensure the safety of the system, the system needs peripheral safety Open-phase detection 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. Contactor Three-phase inductive motor 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. Breaker 3G3JV Inverter Gear box Starter Current leakage detection Three-phase inductive motor 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. 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.
