Fire can result if the Inverter is attached to a combustible material.

D Install a cooling fan or other cooling device when installing more thanone Inverter in

thesame enclosureso thatthe temperatureof the airentering theInvertersis below 45_C.

Overheating can result in fires or other accidents.

J Wiring

D Always turn OFF the input power supply before wiring terminals.

Otherwise, an electric shock or fire can occur.

D Wiring mustbe performed by an authorized person qualified in electricalwork.

Otherwise, an electric shock or fire can occur.

D Be sure to ground the ground terminal.

(200 V class:Ground to 100 : or less,400 V class:Ground to 10 : or less) Otherwise, an electric shock or fire can occur.

D Always check the operationof any emergency stop circuits after they are wired.

Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)

D Never touch the outputterminalsdirectlywith yourhands orallow theoutput lines to

come into contact with the Invertercase. Never short the outputcircuits.

1.1.2 Outline of Control Methods

The VS-626MC5 uses two control methods.

D Open-loop vector control (factory setting) D Flux vector control

PG stands for pulse generator (encoder). Vector control isa method for removinginterferencewithmagnetic flux and torque,andcontrolling torque

according to references. Currentvectorcontrol independently controlsmagneticflux current and torquecurrent by simultaneously

controlling the motorprimary current and phases. Thisensures smooth rotation,high torque,and accurate speed/torque control at low speeds.

If the motorconstants required forvector control arenot known, the motor constantscan be automatically set with autotuning.

The control methods are effective for the following applications:

D Open-loop vector control: General variable-speed drive. D Flux vector control: Simple servodrive, high-precision speed control/torque control.

The control characteristics for each mode are shown in Table 1.2.

Open-loop Flux Vector

1.1.3 Functions

J Autotuning

Autotuning is effectivefor vectorcontrol. It solves problems in applicable motorrestrictions and difficult constant settings. The motor constants are automatically set by entering a value from the motor’s rating nameplate.

Autotuning allows fluxvector control tooperate accurately withvirtually any normalAC induction motor, regardless of the supplier.

Always perform autotuning for motor unit separately before vector control operation.

J Frequency References

Thefollowing five typesoffrequency references can beused to controlthe output frequencyof the Inverter.

D Numeric input from the Digital Operator D Voltage input within a range from 0 to 10 V D Voltageinput within arange from 0 to r10 V (with negative voltages,rotation is in the oppositedirec-

tion from the run command.)

D Current input within a range from 4 to 20 mA D Input from Option Card

Any of the above frequency references can be used by setting a constant. Amaximumof nine frequency references can beregisteredwith the Inverter.Withremote multi-step speed

reference inputs, the Inverter can operate in multi-step speed operation with a maximum of nine speed steps.

J Low Noise

Theoutput transistorof the Inverteris an IGBT (insulated gatebipolar transistor).Using sine-wave PWM with a high-frequency carrier, the motor does not generate metallic noise.

Introduction

1.1.3 Functions

J Monitor Function

The following items can be monitored with the DigitalOperator: Frequencyreference, outputfrequency, output current, motor speed, outputvoltage reference,main-circuit DC voltage, output power,torque reference,statusof input terminals,status of outputterminals, operating status,totaloperating time,software number, speed deviation value, PID feedback value, fault status, fault history,etc.

All types of data can be monitored even with multi-function analog output.

J Bilingual Digital Operator

The Digital Operatorcan displayeither Englishor Japanese.The Digital Operator’s liquid crystal display provides a 16-character x 2-line display area.

Easy-to-read displays allow the advanced functions of the Inverter to be set in interactive operations to input constants, monitoring items, etc. Change the constant setting to select the English display.

J Harmonic Countermeasures (0.4 to 160 kW Models)

The VS-626MC5 Inverters support DC reactors to easily handle high-frequency control guidelines.

D DC reactors (optional) can be connected to 0.4 to 15 kW models. D Models from 18.5 to 75 kW have a built-in DC reactor.

J User Constant Structure and Three Access Levels

The VS-626MC5 has a number of user constants for setting various functions. These user constants are classified into a hierarchy to make them easier to use.

Thelevels areas followsfrom topto bottom:Modes, Groups,Functions, andConstants. The access levels for the user constants are shown in Table 1.3.

Table 1.3 AccessLevels for User Constants

Level Contents Mode Classified according to operation

Groups Classified by application. Functions Classified by function. See user constants. Constants Individualuser constant settings.

TheVS-626MC5 allowsthe following three access levelsto be set in order to further simplify setting user constants. (An access level is a range of user constants that can be referenced or set.)

Quick-Start Reads/sets user constants required for trial operation. [Factory setting] Basic Reads/setsuser constants that are commonly used. Advanced Reads/sets all the user constants that can be used.

In general, press the DATA/ENTER Key to move from an upper to a lower level. This varies somewhat, however, according to the access level, as shown in Fig. 1.1. For the Quick-Start access level, which has fewuser constants that canbe set,pressingthe DATA/ENTERKey jumpsdirectlyto theuser constant level; whereas for the Advanced access level, which has many user constants, pressing the DATA/ENTER Key first leads to the Group level.

The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.

D Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.

The Inverter can be damaged or internal parts burnt if these devices are connected.

D Do not connect electromagnetic switches or contactors to the output circuits.

If a load isconnected whilethe Inverter is operating, surge current will cause the overcurrent protection circuit inside the Inverter to operate.

3.4.5 Wiring the Main Circuits

This section describes wiring connections for the main circuit inputs and outputs.

J Wiring Main Circuit Inputs

Installing a Molded-case Circuit Breaker

Alwaysconnectthe power inputterminals(R, S, andT) and powersupply via amolded-casecircuitbreaker (MCCB) suitable for the Inverter.

D Choose an MCCB with a capacity of 1.5 to 2 times the Inverter’s rated current. D For the MCCB’stime characteristics, be sure to consider the Inverter’soverload protection (one min-

ute at 150% of the rated output current).

D If the same MCCB is to be used for more than one Inverter, or other devices,set up a sequence so that

the power supply will be turned OFF by a fault output, as shown in Figure 3.7.

supply

Installing a Ground Fault Interrupter

Inverter outputs use high-speed switching, so high-frequency leakage current is generated. Therefore,at theInverterprimary side, use aground fault interrupterthat detectsonly the leakage currentin the frequency range that is hazardous to humans and excludes high-frequency leakage current.

D For the special-purpose ground fault interrupter for Inverters, choose a ground fault interrupter with

a sensitivity amperage of at least 30 mA per Inverter.

D When using a generalground fault interrupter,choosea groundfault interrupter with a sensitivityam-

perage of 200 mA or more per Inverter and with an operating time of 0.1 s or more.

Installing a Magnetic Contactor

If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used instead of a molded-case circuit breaker.

Whena magneticcontactoris installedon the primaryside of the main circuitto forcibly stop the Inverter, however,the regenerative braking does not work and the Inverter will coast to a stop.

D The Invertercan be startedand stopped byopening andclosing the magneticcontactor on the primary

side.Frequentlyopening and closing themagneticcontactor,however,may causetheInverterto break down.

D When the Inverterisoperatedwith the Digital Operator,automatic operation cannot be performed after

recovery from a power interruption.

D If theBrakingResistorUnit is used,program the sequence sothat themagneticcontactoristurned OFF

by the contact of the Unit’s thermal overload relay.

Connecting Input Power Supply to the Terminal Block

Input power supply can be connected to anyterminal R, S or T on theterminal block; the phasesequence of input power supply is irrelevant to the phase sequence.

Installing an AC Reactor

Ifthe Inverter is connected to alarge-capacitypower transformer(600 kWormore)or the phaseadvancing capacitor is switched, an excessivepeak currentmay flowthroughtheinput power circuit, causing thecon verter unit to break down.

Toprevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactorto the DC reactor connection terminals.

This also improves the power factor on the power supply side.

Installing a Surge Absorber

Alwaysuse a surge absorberor diode for inductive loads near the Inverter.These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

Wiring the Power Terminals of Inverters with 18.5 to 75 kW Outputs

D For 200 V class Inverters o f 18.5 to 75 kW or 400 V class Inverters of 18.5 to 45 kW, connect the r

terminalsto the Rand S terminals respectively.(These are shorted bya short-circuit bar forship-

and ping.)

D For 400 V class, 55, 75 kW, connect the r and 400 terminals to the R and S terminals respectively.

(These are shorted by a short-circuit bar for shipping.)

Installing a Noise Filter on Power Supply Side

Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

3.4Wiring Main Circuit Terminals

J Wiring on the Output Side of Main Circuit

Connecting the Inverter and Motor

Connect output terminals U, V,and W to motor lead wires U, V, and W, respectively. Check that the motor rotates forward with the forward run command. Switch over any two of the output

terminals to each other and reconnect if the motor rotates in reverse with the forward run command.

Never Connect a Power Supply to Output Terminals

Neverconnecta power supply tooutputterminals U, V,andW.If voltageis applied to theoutput terminals, the internal circuits of the Inverter will be damaged.

Never Short or Ground Output Terminals

If the output terminals aretouched with bare hands orthe outputwires come into contact withthe Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.

Do Not Use a Phase Advancing Capacitor or Noise Filter

Never to connect a phase advancing capacitor or LC/RC noise filter to an output circuit. Doing so may result in damage to the Inverter or cause other parts to burn.

Do Not Use an Electromagnetic Switch or Magnetic Contactor

Donot connect anelectromagneticswitch or magneticcontactorto anoutput circuit. Ifa load isconnected tothe Inverter duringoperation, a surge current willactuatethe overcurrent protective circuit inthe Inverter.

Installing a Thermal Overload Relay

ThisInverter has an electronic thermalprotectionfunction toprotect the motorfrom 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 L1-01 to 0 (no motor protection).

Setthethermaloverloadrelayto the valueon themotornameplatewhenoperating at 50 Hzandto 1.1 times thevalue on the nameplate whenoperating at 60Hz. The sequenceshould be designedso thatthe contacts of the thermal overload relay turn OFF the magnetic contactor on the main circuit inputs.

Installing a Noise Filter on Output Side

Connect a noise filter to the output side of the Inverter to reduce radio noise and inductive noise.

Countermeasures Against Inductive Noise

As described previously, a noise filtercan beused to prevent inductive noise from being generatedon the output side. Alternatively,cables canbe routedthrough a grounded metalpipe toprevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces inductive noise.

Radionoise is generated from theInverteras well asfromthe input andoutput lines. Toreduce 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.

Cable Length between Inverter and Motor

If the cable between the Inverter and the motor is long, the high-frequency leakagecurrent will increase, causingthe Inverter output current toincrease as well.This may affectperipheral devices. Toprevent this, adjust the carrier frequency (set in C6-01) as shown in Table 3.6. (For details, refer to the user constant settings.)

D Always usethe groundterminal of the 200 V Inverter with a ground resistance ofless than100 : and

that of the 400 V Inverter with a ground resistance of less than 10 :.

D Do not share the ground wire with other devices, such as welding machines or power tools. D Always use a ground wire that complies with technical standards on electrical equipment and mini-

mize the length of the ground wire. Leakage current flows through the Inverter.Therefore, if the distance between the ground electrode

andthe ground terminalis toolong, potential on theground terminal oftheInverter will becomeunstable.

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

3.7.1 Installing a PG Speed Control Card

PGSpeedControl Cards are usedforexecuting speed controlusing apulse generator (PG). Thereare fourtypes of PG speed control, as shown below.Select the type that fits the application and control method.

PG-B2 A/B-phase pulse input for open collector output or complementary outputs, for vector control PG-X2 A/B/Z-phase pulse input for line driver input, for vector control

Use the following procedure to install a PG Speed Control Card.

1. Turn off the main-circuit power supply.

2. Leave it off for at least one minute before removing the front cover of the Inverter (or at least three

minutes for Inverters of 30 kW or more). Check to be sure that the CHARGE indicator is OFF.

3. Insert the spacer (which is provided) into the spacer hole in the Inverter’s mounting base.

For Inverters of 3.7 kW or lower,there are two adjacent holes. Insertthe spacerinto the7CN hole.The spacer cannot be easily removed if inserted into the wrong hole. Be very careful to insert the spacer into the correct hole, and in the proper direction.

4. Referring to the enlarged illustration in the following diagram,align thePG Speed Control Card with

the catchposition as shown by (a) and (b) and fit it precisely to the Option-A connector.Insert at (a) first.

5. Pass the spacer through the spacer hole at the Card. (Refer to A in the illustration.) Check to be sure

that it is precisely alignedwith the4CN position,and snap it into the proper position. Be sureto press it in firmly until you hear it snap into place.

Thissectiondescribesthe VS-626MC5’smonitor modes, switchingbetween modes, and accessing/settinguser constants.

4.2.1 Inverter Modes

TheVS-626MC5 Inverter’s user constants andmonitoringfunctions have been organized in groupscalled modes that make it easier to read and set user constants.

The VS-626MC5 is equipped with 5 modes, as shown in the Table4.2.

Table 4.2 Modes

Mode Primary function(s)

Operation mode

Initialize mode

Programming mode

Autotuning mode

Modified constants mode (See note)

Note Always perform autotuning for motor unit separately bofore vector control operation.

The Inverter can be run in this mode. Use this mode when monitoring values such as frequency references or output

current, displaying fault information, or displaying the fault history. Use this mode when selecting the language displayed on the Digital Operator, se-

lecting the access level for reading/setting user constants, selecting the control mode, or initializing the user constants.

Use this mode when reading/setting the user constants required for operation. The program-mode functions are subdivided into the following groups:

S Application: Operation mode selection, DC control, speed search, etc. S Tuning: Acceleration/deceleration times, S-curve characteristics, carrier

S Reference: Settings related to frequency control S Motor: V/f characteristics and motor constants S Option: Settings for Optional Cards S Terminal: Settings for sequential I/O and analog I/O S Protection: Settings for the motor and inverter protection functions S Operator: Selects the Digital Operator’s display and Key functions S Winding : Settings for winding change function (Optional)

(Usable only with in vector control mode) Use this mode when running a motor with unknown motor constants in the vector

control mode. The motor constants are calculated and set automatically. Perform autotuning for motor unit separately before vector control operation.

Use this mode to read/set user constants that have been changed from their factoryset values.

frequencies, etc.

4.2.2 Switching Modes

Once the Inverterhas been put into operation mode by pressing the MenuKey, the Incrementand Decrement Keys can be pressed to switch to other modes. Press the DATA/ENTER Key to read/set the user constants in each mode.

Press the ESC Key to return to the mode display from the user constant display. Press the DATA/ENTER Key twice to write a constant and then press the ESC Key to return to themode

display.This is the most Basic operation, so you should remember it.

Setting User Constants

4.2.3 User Constant Access Levels

The VS-626MC5 has three access levels which divide the various user constants based on their applications, as shown below. The access level restricts which user constants can be set or displayed.

Quick-start Allows reading/setting of user constants required for simple operation. (factory preset)

Basic Allows reading/setting of Basic user constants.

Advanced Allows reading/setting of all user constants.

Set the access level in initialize mode with user constant A1-01.

J Changing the Access Level from Quick-start to Basic

The Inverter is set at the factory to start in the Quick-start access level. Use the following procedure to change from the Quick-start level to the Basic level.

J Setting User Constants in Each Access Level

The displayed access level will change when programming mode is selected. The display will not change for access levels in operation mode, initialize mode, autotuning mode, and modified constants mode.

This section provides the procedure tochange the acceleration timeto 20.0 s in each access level. The acceleration time (C1-01) is a user constant in programming mode.

If the new user constant setting is not written to the Unit by pressing the DATA/ENTER Key within one minute after starting the procedure, the d isplay will automatically revert to the original user constantsetting. In this case, the procedure must be started again.

J Monitoring at Startup

In operation mode, the frequency reference, output frequency, output current, and output voltage can be monitored immediately if the factorypresets are being used.One of these four values, the output voltage, canbe changedto a differentmonitor item. Whenan item other than theoutput voltage is to bemonitored, setthat value inuser constant o1-01 (Monitorselection). Refer to theexample procedure given laterin this manual.

When the power is turned ON, the frequency reference will appear in the Unit’s data display if the factor presets are being used. Any one of the four values monitored at startup (frequency reference, output frequency,output current,or the value set in user constant o1-01) can be selected to appearwhen the power is turned ON.

The value thatappears at startup is determinedby userconstant o1 -02 (Monitor selection afterpower up). User constants o1-01 and o1-02 can be changed in the Basic or Advanced access levels. These user

constants can be changed during operation.

J Monitor Displays

D Disconnect the load (machine, device) from the motor before autotuning.

Themotormayturn, possibly resulting in injuryordamagetoequipment.Also,motorconstantscannotbe correctly set with the motor attached to a load.

Autotuning automatically tunesand setsthe requiredmotor constants when operating in the open-loop or flux vector control modes. Always perform autotuning before starting operation.

When the rated voltage, rated current, rated frequency, and number of poleslisted on the motor nameplate havebeeninput and theRUNKey is pressed, the motorconstantscalculatedfrom these values willbewritten to E1-04 through E2-09 automatically.

When motor cannot be disconnected from the load, motor constants can be set by calculation. Contact your YASKAWA representativesfor details.

The Inverter ’s autotuning function automatically determinesthe motor constants, while a servo system’s autotuning function determinesthe sizeof aload, sothese autotuningfunctions arefundamentally different.
