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.

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.
