!Caution

•Phase rotation of input terminals L1 (R), L2 (S), L3 (T) is availablein either direction, clockwise and counterclockwise.

•When Inverter output terminals T1 (U), T2 (V), and T3 (W) areconnected to motor terminals T1 (U), T2 (V), and T3 (W), respec-tively, motor rotates counterclockwise, viewed from oppositedrive end, upon forward operation command. To reverse the rota-tion interchange any two of motor leads.

•Never connect AC main circuit power supply to output terminalsT1 (U), T2 (V), and T3 (W).

•Care should be taken to prevent contact of wiring leads with the3G3XV cabinet, or a short-circuit may result.

•Never connect the power factor correction capacitor or noise filterto 3G3XV output.

•Never open or close contactors in the output circuit unlessInverter is properly sized.

The withstand voltage between the motor’s phases is insuffi-cient.

When the motor is connected to the Inverter’s output, a surge isgenerated between the Inverter’s switching and the motor’s coil.Normally the maximum surge voltage is three times the Inverter’sinput power supply voltage (i.e., 600 V for 200-V class, and1,200 V for 400-V class). Be sure to use a motor with a withstandvoltage between the motor’s phases that is greater than the maxi-mum surge voltage. In particular, when using a 400-V-classInverter, use a special motor for Inverters.

Wiring

!Section 1-4

Caution

Observe the following guidelines when wiring.

•Lead size should be determined considering voltage drop ofleads. Select the lead size so that the voltage drop will be within2% of the normal rated voltage. The voltage drop can be obtainedfrom the lead resistance (R) in Ω/km, wiring distance (D) inmeters, and current (I) in A using the following equation:

Phase-to-phase voltage drop in volts = √3 ×R ×D ×I ×10–3•Insertion of AC reactor:

When the power supply capacity exceeds 600 kVA, connect anAC reactor at the Inverter input side for power supply coordina-tion. This reactor is also effective in improving the power factorof the power supply.

•Wiring length between Inverter and motor:

If the total wiring distance between the Inverter and motor isexcessively long and the Inverter carrier frequency (main tran-sistor switching frequency) is high, harmonic leakage currentfrom the cable will increase to affect the Inverter Unit or periph-eral devices. If the wiring distance between the Inverter andmotor is long, reduce the Inverter carrier frequency as shownbelow. The carrier frequency can be set with constant No. 40.For details, refer to 2-8-18 Carrier Frequency. The carrier fre-quency is set to 10 kHz at the factory prior to shipping.

Wiring distance between Inverter and motorAllowable carrier frequency(Corresponding setting for constant no. 40)Up to 30 m15 kHz max.(6)Up to 50 m10 kHz max.(4)Up to 100 m5 kHz max.(2)Over 100 m2.5 kHz max.(1)GroundingGround the casing of the 3G3XV using ground terminal G (E).•Ground resistance should be 100 Ω or less.

•Never ground the 3G3XV in common with welding machines,motors, and other large-current electrical equipment, or groundpole. Run the ground lead in a separate conduit from leads forlarge-current electrical equipment.

•Use the ground leads which comply with AWG standards andmake the length as short as possible.

•Where several 3G3XV Units are used side by side, all the Unitsshould preferably be grounded directly to the ground poles. How-ever, connecting all the ground terminals of 3G3XV in parallel,and grounding only one of 3G3XV to the ground pole is also per-missible as shown below. However, do not form a loop with theground leads.

Precautions for Control Circuit WiringTake the following precautions when wiring.

1, 2, 3...1.Separate the control signal line from power lines. Otherwise amalfunction might occur.

2.For the frequency setting signal (analog), use a shielded leadand be sure that the signal is terminated properly.

ShieldedArmorsheath

Never connect

Connect shielded sheathto main circuit groundingterminal G (E).

Insulate these partswith insulating tape

3.The wiring length of the control signal line must be 50 m or less.4.To drive the contact input signal by transistor, use one havingratings of 50 V 50 mA or more. Circuit leakage current at signalOFF must be 100 µA or less.

5.To drive an inductive load (relay coil, etc.) by multifunction pho-to-coupler output, be sure to insert a free wheel diode.

13.14=3G3XV750 mA max.48 V max.Free wheel diode(100V, 100 mA or more)1-5Operation

Check the following items after completion of installation and wir-ing:

•No fault in wiring. Especially, the power supply is connected to theoutput terminals T1 (U), T2 (V), and T3 (W).

•No short-circuit because of wiring contamination (dust, oil, etc.).•Screws and terminals are not loosened. Wiring is provided prop-erly.

•Wiring is not grounded.•Load status is good.

For safe operation, before operation, the motor must be able tooperate alone by separating it from the coupling or belt which con-nects the motor and machine.

When the motor is operated with the machine directly connected,pay close attention.

Motor Rated CurrentSetting

Since the Inverter is provided with electronic thermal overload pro-tective function in order to protect the motor from overheating, setthe rated current value described on the motor name plate to con-stant (no. 19). Standard 4-pole motor current value is set as the ini-tial value. For details refer to 2-8-8 Electronic Thermal OverloadFunction.

Provide a thermal relay or thermal protector when more than onemotor is operated simultaneously.

The Inverter can be operated using the Digital Operator or controlcircuit terminal inputs. Models with Digital Operator are set to“OPERATOR MODE BY DIGITAL OPERATOR” prior to shipping.

Note

•Motor rotating direction is proper.

•Motor does not have abnormal vibration or beat.•Accel/decel is smooth.

OperationPrecautions

Section 1-5

•The motor does not start up if both FWD and REV run signals areturned on simultaneously. If they are turned on simultaneouslyduring run, the motor decelerates to a stop.

•When output frequency reaches 1.5 Hz (set value prior to ship-ping) at deceleration, the dynamic brake (DB) operates for 0.5 sand metallic noise is generated by the motor. However, this noiseis normal.

•If a fault occurs during acceleration or deceleration and the motorcoasts to a stop, check the motor stopping position and then thefollowing items:

a)Load is not excessively large.

b)Accel/decel time is long enough for load.

Resetting must be performed by external signal input (or DigitalOperator’s RESET Key) or by turning off the power supply.

Since the latest fault content data are stored in the Inverter, even ifthe power supply is turned off, they can be monitored after thepower supply is turned on again.•Checking fault contents

The latest data are stored in the constant No. 48. (except uU)•Clearing fault contents

The fault contents alone can be cleared by setting the value ofconstant No. 00 to 6. The fault contents will also be clearedwhen constants are initialized by setting constant No. 00 to 8 or9. Other constants will also be initialized, so record the con-stant data before initialization.•Faults to be stored

OC (overcurrent), OV (overvoltage), OH (cooling fan over-heat), OL1 (motor overload), OL2 (Inverter overload), OL3(overtorque detection), EF4, EF5 (external fault), CPF05 (ADconverter fault).

•The compensation frequency (fc) can be obtained from the fol-lowing.

If the output frequency is lower than the constant set in no-04for the maximum voltage frequency, use the following formulato obtain the compensation frequency (fc).

fc = no-04 x no-57 x [output current – (no-19 xno-58/100)]/[no-19 x no-58/100)]

If the output frequency is equal to or higher than the constantset in no-04 for the maximum voltage frequency, use the follow-ing formula to obtain the compensation frequency (fc).

fc = output frequency x no-57 x [output current – (no-19 xno-58/100)/[no-19 – (no-19 x no-58/100)no-04: Maximum voltage frequency (Hz)

ExplanationMonitor display appears when the main circuit DCvoltage drops under the detection level while theInverter output is off.This function is used to protect the machine and tomonitor the Inverter’s output torque.The Inverter output reacts in a preset manner whenthe Inverter output current exceeds the over torquedetection level. The monitor display blinks when“operation continue” is preset.Inverter acceleration is stopped when 170% of ormore of the Inverter rated current is required by theload.This prevents overload protection (OL2) or overcur-rent (OC) from occurring.When current is reduced to less than 170%, accel-eration is enabled.MonitorFault con-displaytact output(UV)Non uU(Blink)operation(OL3)Non %l3(Blink)operationProtection functionLow-voltage protection(main circuit voltageinsufficient)Overtorque detectionStall pre-vention(Accel/decelis accom-plished withmaximumcapacity oftheInverterthe Inverterwithout trip-ping onovercurrentor overvol-tage.)Duringaccelera-tion---Non operationDuring nor-Output frequency is decreased when 160% of themal opera-Inverter rated current or greater is required by thetionload.
