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.

Actual

Size

Three-phase 100 W at 200 V 68 x 128 x 78.5 mm (W x H x D)

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.

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 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.

Standard models meet CE and UL/cUL standards.

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

labor.

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 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 performs flexible speed control of a compact agitator or separator.

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.

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)

Value	Name	Setting	Unit of	Default
		range	setting	set-
				tings
n16	Acceleration time 1	0.0 to 999	0.1 s	10.0

2	S-shape acceleration/deceleration characteristic time is 0.5 s
3	S-shape acceleration/deceleration characteristic time is 1.0 s

		mand

Note: 1. Values will be set in 0.1-Hz increments if the frequency is less than 100 Hz and 1-Hz increments if the frequency is 100 Hz or over.

2.Frequency reference 1 is enabled with n03 for frequency reference selection set to 1. (Remote mode)

3.Frequency references 1 to 8 are enabled by setting multistep speed references 1, 2, and 3 in n36 to n39 for multi-func- tion input. Refer to the following table for the relationship between multi-step speed references 1 to 3 and frequency references 1 to 8.

Frequency	Multi-step speed	Multi-step speed	Multi-step speed
reference	reference 1	reference 2	reference 3
Frequency	OFF	OFF	OFF

Note: 1. “ON” and “OFF” represent “input ON” and “input OFF,” respectively.

2.Inching frequency commands take precedence over multistep speed references.

Note: 1. The default setting does not need any changes in normal operation.

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.
