Therefore, touching terminals immediately after turning the power off may cause an electrical shock.If an inspection or some other task is to be performed, always wait at least one minute from the time all indicators on the front panel go off.(Note that this warning is applicable whenever you perform any task after turning the main circuit off.)H Do Not Remove the Digital Operator When the Main Circuit is Still On.Always turn the main circuit off before removing the digital operator.Removing the digital operator with the main circuit ON may cause an electrical shock and damage the equipment.H Do Not Modify Wiring or Check Signals When the Main Circuit is On.Always turn the main circuit off before modifying wiring or checking signals. Touching terminals while the main circuit is on may cause an electrical shock and dam-age the equipment.H Do Not Conduct a Dielectric Strength Test.Because the 3G3EV Inverter is an electronic control unit using semiconductor, never conduct a dielectric strength test or an insulation resistance test for the control circuit.H Modify Constant Settings Correctly.Always modify the constant settings according to the procedures described in this manual.1-4Chapter 2Overview2-1Features2-2Component Names2-22-1Features H Easy to UseD Basic Constants Displayed On IndicatorsConstants for basic operations such as frequency setting and acceleration/deceleration time setting are displayed on dedicated indicators. Therefore, constant numbers can be confirmed easily.D Minimum Constant Setting ItemsConstant setting items have been minimized to enable even first-time users to set constants easily.H Easy to InstallD Very Small and LightweightThe 3G3EV Inverter is approximately half the size of our Low-noise General-purpose Inverters in terms of volume and weight percentage. This improves space efficiency and operating efficiency (including easier removal).D Optional DIN TrackAn optional DIN track is available. This DIN track enables the user to mount the 3G3EV Inverter on the DIN track with a one-touch operation.OverviewChapter 2Overview Chapter 2 H Easy to WireD Easy Wiring without Having to Open the Front CoverThis Inverter can be wired just by opening the terminal block cover.D Separate Input and Output Terminal BlocksPower input terminals are located in the upper section, while motor output terminals are in the lower section. In this way, the input and output terminal blocks are separated ac-cording to the contactors, so incorrect wiring can be prevented.D Soldering No Longer NecessaryNo connector means no soldering.H Easy to OperateD Switching the Operation Mode with a One-touch OperationFor example, after a test run is performed using the Digital Operator, it can be easily switched to a production run using control terminals with a one-touch operation.D Checking a Test Run with Various MonitorsOutput frequency, output current, and the direction of motor rotation appear in the dis-play section of the Digital Operator, so the mechanical system can be easily monitored during a test run.H Low NoiseAn insulated gate bipolar transistor (IGBT) power element has been adopted to elimi-nate metallic noise.H High-torque Operation Even in Low Speed RangeA torque rate of 150% can be achieved even in a low speed range where output frequen-cy is only 3 Hz. Thus, acceleration time can be reduced.H Various Input Power SuppliesA 400-VAC-class Inverter has been newly added to the 3G3EV Series to cope with vari-ous power supplies.•Three-phase 200-VAC input:0.1 to 1.5 kW•Single/Three-phase 200-VAC input:0.1 to 1.5 kW•Three-phase 400-VAC input:0.2 to 1.5 kW2-32-42-2Component NamesH Main UnitMain Circuit Terminals (Input)Power input terminals Braking resistor connection terminalsRun indicator Alarm indicatorControl circuit terminals(output)Ground terminalMain Circuit Terminals (Output)Motor output terminalsDigital OperatorControl circuitterminals (input)MAMBMCSF SR S1SC FS FR FCH Digital OperatorDisplaysectionOperationkeysMode Key Increment KeyRUN KeyData display sectionMonitor item indicatorsIn-service item indicators (green indicators)These items can be monitored or set evenduring operation.Stopped item indicators (red indicators)These items can be set only when theInverter is stopped.Constant item indicatorsEnter KeyDecrement KeySTOP/RESET Key2-5Chapter 3Design3-1Installation3-2Wiring3-1Installation3-1-1Outside/Mounting DimensionsNote All dimensions are in millimeters.H3G3EV-A2001(-j) to 3G3EV-A2004(-j) (0.1 to 0.4 kW):Three-phase 200-VAC InputH3G3EV-AB001(-j) to 3G3EV-AB002(-j) (0.1 to 0.2 kW): Single/Three-phase 200-VAC Input4.5 dia.Note1.For the 3G3EV-A2001(-j), 3G3EV-A2002(-j), and 3G3EV-AB001(-j), a U-shaped notch (4.5 mm wide) is provided instead of the upper mounting hole (4.5 mm in diameter).Note2.Install the Inverter with two M4 bolts.3-2D Three-phase 200-VAC Input Model3-3H3G3EV-A2007(-j) to 3G3EV-A2015(-j) (0.75 to 1.5 kW): Three-phase 200-VAC Input3G3EV-AB004(-j) to 3G3EV-AB015(-j) (0.4 to 1.5 kW): Single/Three-phase 200-VAC Input3G3EV-A4002(-j) to 3G3EV-A4015(-j) (0.2 to 1.5 kW): Three-phase 400-VAC InputTwo, 4.5 dia.Note Install the Inverter with four M4 bolts.3-43-5D Three-phase 400-VAC Input Model3-1-2Installation ConditionsH Installation Site•Install the Inverter under the following conditions:Ambient temperature for operation: –10°C to 50°C Humidity: 90% RH or less (non-condensing)•Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally enclosed panel that is completely shielded from suspended dust.•When installing or operating the Inverter, always take special care so that metal pow-der, oil, water, or other foreign matter do not get in the Inverter.•Do not install the Inverter on inflammables such as wood.H Direction of Installation•Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.H Installation Space•When installing the Inverter, always provide the following installation space to allow normal heat dissipation from the Inverter:W= 30 mm min.100 mm min.100 mm min.AirSideAirI n v e r t e rI n v e r t e rI n v e r t e rH Ambient Temperature Control•To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature rises.•If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50°C.•The surface temperature of the Inverter may reach 30°C higher than the ambient tem-perature. Therefore, keep all thermally susceptible devices and wires away from the Inverter.H Protecting the Inverter from Foreign Matter during Installation •Place a cover over the Inverter to shield it from metal powder produced by drilling dur-ing installation.(Upon completion of installation, always remove the cover from the Inverter. Other-wise, ventilation will be affected, causing the invert to overheat.)3-63-73-2Wiring3-2-1Terminal BlocksH Name of Each Terminal BlockMain Circuit Terminals (Input)Power input terminalsBraking resistorconnection terminalsControl circuit terminals (output)Ground terminal Main circuit terminals (output)Motor Output Terminals (Output)Control circuit terminals (input)MAMBMCSF SR S1SC FS FRFCH Main Circuit TerminalsNote Before shipping, a resin plate is attached to each braking resistor connection ter-minal to prevent incorrect wiring.When connecting a braking resistor, always remove the resin plates with a pair of long-nose pliers.Terminal block screw (M3.5)Crimpterminal6.2 mm max.H Control Circuit TerminalsD Input Terminals (On Right-hand Side)No external power supply is required because a built-in power supply is provided.24 VDC, 8 mA(See note3)(See note 3)Input impedanceIn ut im edanceNote1.Constant No. 06 (n06) is used to set this function.

Therefore, always follow the instructions given below when connect-ing the Inverter to peripheral devices and other parts.H Wire Size and Molded-Case Circuit Breaker to be UsedFor the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables. If the cable is long and may cause voltage drops, increase the wire size according to the cable length.Note Tighten the M3.5 terminal screw to the torque of 0.8 N S m.Determining the Wire SizeDetermine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage.Line voltage drop V D is calculated as follows:V D (V) = p3 x wire resistance (Ω/km) x wire length (m) x amperage (A) x 10–3H Wiring on the Input Side of Main CircuitD Installing a Molded-case Circuit BreakerAlways connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker. Power must be supplied instantaneously. Unstable power startup will not start the Inverter.D Installing a Ground Fault InterrupterIf a ground fault interrupter is to be connected to the wire on the primary side (R, S, and T) of the main circuit, use either of the following interrupters to prevent malfunctions:•Ground fault interrupter with a sensitivity amperage of 200 mA or more and with an operating time of 0.1 second or more•Ground fault interrupter with high-frequency countermeasures (for Inverter)D Installing a Magnetic ContactorThis Inverter can be used without a magnetic contactor (MC) on the power supply side. If the power supply for the main circuit is to be shut off because of the sequence, a mag-netic contactor can be used instead of a molded-case circuit breaker.However, when a magnetic contactor is installed on the primary side of the main circuit to forcibly stop a load, note that regenerative braking does not work and the load coasts to a stop.•A load can be started and stopped by opening and closing the magnetic contactor on the primary side. Note, however, that frequently opening and closing the magnetic contactor may cause the Inverter to break down.•When the Inverter is operated with a Digital Operator, automatic operation cannot be performed after recovery from a power interruption.D Connecting Input Power Supply to the Terminal BlockBecause the phase sequence of input power supply is irrelevant to the phase sequence (R, S, T) of the terminal block, input power supply can be connected to any terminal on the terminal block.D Installing an AC ReactorIf the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advance capacitor is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down. T o prevent this, install an optional AC reactor on the input side of the Inverter. This also improves the power factor on the power supply side.D Installing a Surge AbsorberAlways use a surge absorber or diode for the inductive loads to be connected to the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.D Wiring of Braking Resistor/Braking Resistor UnitWhen using an Inverter for loads with a large inertia or for vertical axis loads, regenera-tive energy will be fed back.If the regenerative energy exceeds the Inverter capacity, overvoltage will be detected in the main circuit. In such a case, use a Braking Resistor or Braking Resistor Unit. Note Be sure to create a sequence that will turn OFF the Inverter power supply when resistor overheating occurs. When using a Braking Resistor, be sure to install a thermal relay to detect resistor overheating. When using a Braking Resistor Unit, use an error output contact. Otherwise, a fire may occur.Note Do not use a Resistor whose resistance is below the minimum connected resis-tance. Otherwise, the Inverter will be damaged.D Installing a Noise Filter on the Power Supply SideInstall a noise filter to eliminate noise transmitted between the power line and the Inverter.Wiring Example 13G3IV-PHF3G3EVPower supplyNoise filterSYSMAC,etc.Other controllersNote Use a special-purpose noise filter for Inverters.Wiring Example 23G3EVGeneral-purpose noise filterPower supplySYSMAC,etc.Other controllers3G3EVPower supplyGeneral-purpose noise filterSYSMAC,etc.Other controllersNote Do not use a general-purpose noise filter.H Wiring on the Output Side of Main CircuitD Connecting the Terminal Block to the LoadConnect output terminals U, V, and W to motor lead wires U, V, and W, respectively.D Never Connect Power Supply to Output TerminalsCaution Never connect a power supply to output terminals U, V, and W.If voltage is applied to the output terminals, the internal mechanism of the Inverter will be damaged.D Never Short or Ground the Output TerminalsCaution If the output terminals are touched with bare hands or the output wires comeinto contact with the Inverter casing, an electric shock or grounding will occur.This is extremely hazardous. Also, be careful not to short the output wires.D Do Not Use a Phase Advance Capacitor or Noise FilterNever connect a phase advance capacitor or LC/RC noise filter to the output circuit. Do-ing so may result in damage to the Inverter or cause other parts to burn.D Do Not Use an Electromagnetic SwitchDo not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is connected to the Inverter during operation, an inrush current will actuate the overcurrent protective circuit in the Inverter.D Installing a Thermal RelayThis Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set to “0.0” (no thermal protection) for constant No. 31 (“THR” indicator).In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is turned off by the contact of the thermal relay.D Installing a Noise Filter on the Output SideConnect a noise filter to the output side of the Inverter to reduce radio noise and induc-tion noise.3G3EV3G3IV-PLFPower supplyNoise filterSignal lineControllerInduction noise Radio noise AM radioInduction Noise:Electromagnetic induction generates noise on the signal line, causingthe controller to malfunction.Radio Noise:Electromagnetic waves from the Inverter and cables cause thebroadcasting radio receiver to make noise.D How to Prevent Induction NoiseAs described above, a noise filter can be used to prevent induction noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction noise.3G3EV30 cm min.MCCBMetal pipePower supplySignal lineControllerD How to Prevent Radio NoiseRadio noise is generated from the Inverter as well as the input and output lines. To re-duce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.The cable between the Inverter and the motor should be as short as possible.3G3EVPower supplySteel boxNoise filterNoise filterMetal pipeD Cable Length between Inverter and MotorIf the cable between the Inverter and the motor is long, the high-frequency leakage cur-rent will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. T o prevent this, adjust the carrier frequency (set in n37) as shown in the table below.H Ground Wiring•Always use a ground terminal with the following ground resistance.200-VAC Class:100 Ω or less400-VAC Class:10 Ω or less•For 400-VAC-class models that conform to EC Directives, also connect to the neutral of the power supply.•Do not share the ground wire with other devices such as a welder or power tool.•Always use a ground wire that complies with technical standards on electrical equip-ment. Route the ground wire so that the total length is as short as possible.•When using more than one Inverter, be careful not to loop the ground wire.3-2-3Wiring Control Circuit TerminalsThe control signal line must be 50 m or less and must be separated fromthe power line. If frequency references are input externally, use a twisted-pair shielded line.H Wiring Sequence Input/Output TerminalsWire the sequence input terminals (SF, SR, S1, and SC) and the multi-function contact output terminals (MA, MB, and MC) as described below.D Wiring Method•Wire each terminal as follows:a)Loosen the terminal screw with a thin-slotted screwdriver.b)Insert the wire from underneath the terminal block.c)Tighten the terminal screw firmly.•Always separate the control signal line from the main circuit cables and other power cables.Thin-slotted screwdriverLength of stripped portion: Approx. 5.5 mmWireControl circuitterminal blockDo not solder this portion. (Otherwise, faulty contact may result.)H Wiring Frequency Reference Input TerminalsIf frequency references are input using a D/A unit (digital-to-analog converter) or exter-nal power supply, wire the frequency reference input terminals (FR and FC) as de-scribed below.3-18。

使用好变频器是一门实践性很强的学问，有人说，使用好变频器的难易程度并不亚于使用好一台个人电脑。

但是，现在社会上已有的有关变频器技术资料，多为变频器的设计。

制造方面的专著，即使学习和掌握了这方面内容的学生，到了工程现场，仍不能正确使用和操作变频器，这是由于有关使用变频器的资料太少，更不要说变频器的实训装置了，而社会上需要正确使用变频器的技术人员显然比设计制造变频器的技术人才要多的多，针对这一情况，我公司设计了变频器实训模块，并将撰写有关变频器使用技能的教材供本科、大专、高职中专等各类学校相关专业选用，尤其适用职业技术教育。

我公司设计的实训模块选用的是欧姆龙的3G3JV AB007型，就可触类旁通掌握其它厂家的变频器的使用方法与技能。

欧姆龙变频器G3JV-AB007型实训指导书亚龙科技集团有限公司前言随着电力电子技术、微电子技术、计算机控制技术及自动化控制理论的发展,变频器制造技术有了跨越式的进步,以变频器为核心的交流电机调速已广泛应用于国民经济各部门,在工业自动化领域,交流电机调速已经取代传统的直流调速系统,而且大大提高了技术经济指标。

在耗电大户的风机、泵类(其耗电量几乎占工业用电一半,应用变频器控制,可以大大节约电能;在广泛关系各行各业的机械专业,应用变频器技术,是改造这一传统产业,实现机电一体化的重要手段;此外,在化纤、纺织塑料、化学、轻工等工业领域,应用变频器技术。

实现自动化提高了产品的质量与数量变频器不仅应用于工业、交通领域,而且已进入家庭,在家电工业领域,空调器、电冰箱都有了变频器控制的相应产品,提高了家电产品的经济技术指标和智能化水平。

随着现代化的程度提高,队变频器的应用会更加普及。

使用好变频器是一门实践性很强的学问,有人说,使用好变频器的难易程度并不亚于使用好一台个人电脑。

但是,现在社会上已有的有关变频器技术资料,多为变频器的设计。

制造方面的专著,即使学习和掌握了这方面内容的学生,到了工程现场,仍不能正确使用和操作变频器,这是由于有关使用变频器的资料太少,更不要说变频器的实训装置了,而社会上需要正确使用变频器的技术人员显然比设计制造变频器的技术人才要多的多,针对这一情况,我公司设计了变频器实训模块,并将撰写有关变频器使用技能的教材供本科、大专、高职中专等各类学校相关专业选用,尤其适用职业技术教育。

我公司设计的实训模块选用的是欧姆龙的3G3JV AB007型,就可触类旁通掌握其它厂家的变频器的使用方法与技能。

学生可以在实训台上了解变频器的结构、安装及接线的基本知识,进而学会使用变频器的基本技能,包括参数设定和操作方法,控制回路接线端子的设置,接线及智能化功能,功能参数的设置,变频器的维护等进行实际操作培训.在此基础上可以对模拟的实际工业控制系统:恒压供水系统、中央空调冷水系统,泵自动切换控制系统的模拟设计和调试,完成一个变频器工程题的实际操作训练,以满足社会生产实践的需要。

3G3FV系统驱动器具有高性能直流驱动器的功能，若装入一个反馈编码器，就可拥有交流感应电动机的全部功能。

·在未启动时应向挤压机，起重机和提升机提供150%转矩。

·杰出的速度调节来源于高韧性全自动速度调节系统。

·精确的转矩控制来源于全自动内置流动调节系统。

若没有使用反馈编码器，可开启循环流动向量。

后者包括一种独特的向量控制系统，可确保运行速稳定并将100%转矩降到1 Hz。

结构菜单A部分：初始化请注意●运行时只能使用A1-00或A1-02。

●切换流动失量与V/F控制时，建议先停机。

否则会导致OPE02故障。

●仅当02-03=1及A2-_不空时可进行使用常数的初始化。

参量转换图例：A1-00●按下输入键可降低一个水平。

●按下取消键可升高一个水平。

●按下上下键可在同一水平内选择参数组。

A1-01参数存取A1-01=00 可完成监视功能。

A1-01=01仅可显示A2存储器中的参数。

最多可存储参数。

若A2存储器内没安装02-03，A2_参数上述选择将无法显示。

A1-01=02~04 请参照表格。

使用：快速参考表请注意：·在流动矢量关闭的情况下切换到V/F控制会发生OPE02故障。

确保设备中全部输入输出功能要与V/F兼容。

例如：在返回V/F时若输入一个信息到服务器中就会出现故障。

·改变运行方式重新回到生产默认状态。
