H Wiring on the Input Side of the Main Circuit

D Installing a Molded-case Circuit Breaker

Alwaysconnect thepowerinputterminals(R/L1,S/L2,andT/L3) andpowersupplyviaa molded case circuit breaker (MCCB) suitable to the Inverter.

·Install one wiring circuit breaker per Inverter.

·Choose an MCCB with a capacity of 1.5 to 2 times the Inverter’s rated current.

·For the MCCB’s time characteristics, be sure to consider the Inverter’s overload

protection (one minute at 150% of the rated output current).

·IftheMCCB istobeusedincommonamongmultiple Inverters,orotherdevices,setup a sequence such thatthe power supply will be turned OFF by a fault output, asshown in the following diagram.

3-phase/ Single-phase 200 VAC 3-phase 400 VAC

Power supply

Inverter

Fault output (NC)

(see note)

Note Use a 400/200 V transformer for a 400-V model.

D Installing a Ground Fault Interrupter

Inverteroutputsuse high-speed switching, so high-frequency leakage current is generated.

Ingeneral, aleakagecurrent ofapproximately100 mAwilloccur foreachInverter(when the power cable is 1 m) and approximately 5 mA for each additional meter of power cable.

Therefore, at the power supply input area, use a special-purpose breaker forInverters, which detects only the leakage current in the frequency range that is hazardous to humans and excludes high-frequency leakage current.

Design Chapter 2

Page 49

2-26

·For the special-purpose breaker for Inverters, choose a ground fault interrupter with a sensitivity amperage of at least 10 mA per Inverter.

·When using a generalleakagebreaker,choose a ground fault interrupter with asensitivity amperage of 200 mA or more per Inverter and with an operating time of 0.1 s or more.

D Installing a Magnetic Contactor

If the power supplyof the main circuit is to be shut off because ofthe sequence, amagnetic contactor can be used instead of a molded-case circuit breaker.

When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly,however, the 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. Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down.

·WhentheInverterisoperated withtheDigitalOperator,automaticoperation cannotbe performed after recovery from a power interruption.

·WhenusingtheBrakingResistorUnit,besuretoarrangeasequence inwhichthethermal relay of the Unit turns the magnetic contactor OFF.

D Connecting Input Power Supply to the Terminal Block

Inputpowersupplycanbeconnectedto any terminal on the terminal block because the phasesequence of input power supply isirrelevantto the phase sequence (R/L1,S/L2, and T/L3).

D Installing an AC Reactor

If the Inverter is connected to a large-capacity power transformer (660 kW or more) or the external phase advance capacitor of the customer is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down.

To 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 Absorber

Always use a surge absorber or diode for the inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoid, and magnetic brakes.

Design Chapter 2

Page 50

2-27

D Installing a Noise Filter on the Power Supply Side

The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to the power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission.Conversely, noise canalsobereducedfrom thepowerlinetothe Inverter.

Wiring Example

Note Use a special-purpose Noise Filter for the SYSDRIVE 3G3MV. A general pur-

pose noise filter will be less effective and may not reduce noise. Please, use the noise filters as explained in Chapter 9-2.

H Wiring on the Output Side of the Main Circuit

D Connecting the Terminal Block to the Load

Connect output terminals U/T1, V/T2, and W/T3 to motor lead wires U, V, and W. Check that the motor rotates forward with the forward command. Forward meansshaft

of the AC motor rotates in CCW (Counter Clock Wise), if you look from shaft to motor end.Switch overanytwooftheoutputterminalsto eachotherandreconnectif themotor rotates in reverse with the forward command.

D Never Connect a Power Supply to Output Terminals

Never connect a power supply to output terminals U/T1, V/T2, or W/T3. Ifvoltageis appliedtotheoutput terminals,theinternal circuitofthe Inverterwillbedam-

aged.

D Never Short or Ground Output Terminals

Ifthe outputterminalsaretouchedwithbare handsorthe outputwirescome intocontact withtheInvertercasing, an electric shockorgroundingwilloccur.Thisis extremely hazardous.

Also, be careful not to short the output wires.

Design Chapter 2

Page 51

2-28

D Do not Use a Phase Advancing Capacitor or Noise Filter

Never connect a phase advance capacitor or LC/RC Noise Filter to the output circuit. Doing so will result in damage to the Inverter or cause other parts to burn.

D Do not Use an Electromagnetic Switch of Magnetic Contactor

Do not connect an electromagnetic switch of magnetic contactor to the output circuit. If a load is connected to the Inverter during running, an inrush current will actuate the

overcurrent protective circuit in the Inverter.

D Installing a Thermal Relay

The 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 multipolar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set n037 to 2 (no thermal protection).

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 Countermeasures against Induction Noise

As described previously, 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.

D Countermeasures against Radio Interference

Radio noise is generated from the Inverter as well as the input and output lines. To reduce 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.

D Cable Length between Inverter and Motor

As the cable lengthbetween the Inverter and the motor is increased, the floating capa-city between the Inverter outputs and the ground is increased proportionally. The increase in floating capacity at the Inverter outputs causes the high-frequency leakage current to increase, and this may adversely affect peripheral devices and the current detectorin theInverter’soutputsection.Topreventthis fromoccurring,use acableofno more than 100 meters between the Inverter and the motor.If the cable must be longer than100 meters, take measures to reducethefloating capacity by notwiring in metallic ducts, by using a separate cable for each phase, and so on.

Also adjust the carrierfrequency (set in n80) according to the cable length between the Inverter and the motor, as shown in the table below.

H Ground Wiring

·Alwaysusethe groundterminalof the200-VInverterwithagroundresistanceof100W or less. Similarly, always use the ground terminal of the 400-V Inverter with a ground resistance of 10 W or less.

·Do not share the ground wire with other devices such as welding machines or power tools.

·Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance between the groundelectrode andtheground terminalistoo long,thepotential onthegroundterminal of the Inverter will become unstable.

·When using more than one Inverter, be careful not to loop the ground wire.

H Harmonics

D Definition

Harmonics consist of electric power produced from AC power and alternating at frequencies that are integral multiples of the frequency of the AC power.

The following frequencies are harmonics of a 60- or 50-Hz commercial power supply. Second harmonic: 120 (100) Hz Third harmonic: 180 (150) Hz

Second harmonic (120 Hz)

Basic frequency (60 Hz)

Third harmonic (180 Hz)

Problems Caused by Harmonics Generation

Thewaveformofthe commercial power supplywillbedistortedifthecommercialpower supply contains excessive harmonics.Machines with such a commercial power supply will malfunction or generate excessive heat.

Basic frequency (60 Hz) Third harmonic (180 Hz)

Distorted current wave form

D Causes of Harmonics Generation

·Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC power. Such AC power, however, contains harmonics due to the difference in current flow between DC and AC.

Obtaining DC from AC Using Rectifiers and Capacitors

DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and smoothing the pulsating one-side voltage with capacitors. Such AC current, however, contains harmonics.

Design Chapter 2

Page 56

2-33

Inverter

The Inverter as well as normal electric machines has an input current containing harmonics because the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine.

TheDCreactorsuppresses harmonics better thantheACreactor.TheDCreactorused with the AC reactor suppresses harmonics more effectively.

The input power factor of the Inverter is improved by suppressing the harmonics of the input current of the Inverter.

Connection

Connect the DC reactor to the internal DC power supply of the Inverter after shutting OFF the power supply to the Inverter and making sure that the charge indicator of the Inverter turns OFF.

Do not touch the internal circuitry of the Inverter in operation, otherwise an electric shock or burn injury may occur.

H Connecting the Braking Resistor and Braking Resistor Unit

Whenrunning aloadwithalargeinertiaora verticalaxis,regenerationenergywill return to the Inverter. If OV (overvoltage) is generated during deceleration, this indicates that the regeneration energy is exceeding the capacity of the Inverter. In this case, use a Braking Resistor or a Braking Resistor Unit.

·Connect the Braking Resistor as shown in the following diagram.

Note 1. When using a Braking Resistor, install a thermal relay to monitor the tempera-

ture of the resistor.

Note 2. When using a Braking Resistor or a Braking Resistor Unit, be sure to include a

sequence whereby the power supply for the Inverter will be turned OFF in the case of abnormal overheating. Not doing so may result in burning.

S Braking Resistor: Use the output of the thermal relay used to monitor the tempera-

ture of the thermometer.

S Braking Resistor Unit: Use the error contact output of the Braking Resistor Unit.

Explanation

Monitors the frequency reference. Press the RUN Key. The RUN Indicator will be lit. Turn the FREQ adjuster clockwise slowly.

The monitored frequency reference will be displayed.

The motor will start rotating in the forward direction according to the frequency reference.

Press the MODE Key to turn ON the F/R indicator. “For” will be displayed.

Use the Increment or Decrement Key to change the direction of motor rotation. The direction of motor rotation selected will be enabled when the display is changed after the Key is pressed.

·After changing thefrequency reference or therotation direction, check thatthere is no vibration or abnormal sound from the motor.

·Check that no faults have occurred in the Inverter during operation.

H Stopping the Motor

·On completion of operating the motor in the no-load state in the forward or reverse direction, press the STOP/RESET Key. The motor will stop. (The RUN indicator will flash until the motor stops.)

6 Actual Load Operation

·After checking the operation with the motor in no-load status, connect the mechanical system and operate with an actual load.

Note Beforeoperatingthe DigitalOperator,checkthat theFREQadjusteris settoMIN.

H Connecting the System

·After confirming that the motor has stopped completely, connect the mechanical system.

·Be sure to tighten all the screws when fixing the motor axis in the mechanical system.
