If the phase sequence is incorrect, the motor will operate in reverse and that may result in

injury.

•Wiring must be done after installation.

If wiring is done prior to installation that may result in injury or electric shock.

•The following steps must be performed before wiring.

(1) Turn off all input power.

(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.

(3) Use a tester that can measure DC voltage (800VDC or more), and check to make sure

that the voltage to the DC main circuits (across PA-PC) is 45V or less.

If these steps are not properly performed, the wiring will cause electric shock.

•Tighten the screws on the terminal board to specified torque.

If the screws are not tightened to the specified torque, it may lead to fire.

•Check to make sure that the input power voltage is +10%, -15% of the rated power volt-

age written on the rating label (±10% when the load is 100% in continuous operation)

If the input power voltage is not +10%, -15% of the rated power voltage (±10% when the

load is 100% in continuous operation) this may result in fire.

1.4 Notes on the application

1.4.1 Motors

When the VF-S9 and the motor are used in conjunction, pay attention to the following items.

Warning

Mandatory

Use an inverter that conforms to the specifications of the three-phase induction motor and power supply

being used. If the inverter being used does not conform to those specifications, not only will the three-

phase induction motor not rotate correctly, but it may causes serious accidents through overheating and

fire.

Comparisons with commercial power operation.

The VF-S9 Inverter employs the sinusoidal PWM system. However, the output voltage and output cur-

rent do not assume a precise sine wave, they have a distorted wave that is close to sinusoidal wave-

form. This is why compared to operation with a commercial power there will be a slight increase in mo-

tor temperature, noise and vibration.

Operation in the low-speed area

When running continuously at low speed in conjunction with a general purpose motor, there may be a

decline in that motor's cooling effect. If this happens, operate with the output decreased from rated

load.

If you want to run continuously low speed operations at rated torque, please use the VF motor made

especially for Toshiba inverter. When operating in conjunction with a VF motor, you must change the

inverter's motor overload protection level to "VF motor use ( )".

Adjusting the overload protection level

The VF-S9 Inverter protects against overloads with its overload detection circuits (electronic thermal).

The electronic thermal's reference current is set to the inverter's rated current, so that it must be ad-

justed in line with the rated current of the general purpose motor being used in combination.

High speed operation at and above 60Hz

Operating at frequencies greater than 60Hz will increase noise and vibration. There is also a possibility

that such operation will exceed the motor's mechanical strength limits and the bearing limits so that you

should inquire to the motor's manufacturer about such operation.

Method of lubricating load mechanisms.

Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the lubri-

cating effect. Check with the manufacturer of the reduction gear to find out about operable gearing

area.

E6580757

A-11

Extremely low loads and low inertia loads

The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of

50 percent or under of the load percentage, or when the load's inertia moment is extremely small. If that

happens reduce the carrier frequency.

Occurrence of instability

Unstable phenomena may occur under the load and motor combinations shown below.

Combined with a motor that exceeds applicable motor ratings recommended for the inverter

Combined with special motors such as explosion-proof motors

To deal with the above lower the settings of inverter carrier frequency.

(Do not set to 2.2kHz or lower during vector control).

Combined with couplings between load devices and motors with high backlash

In this case, set the S-pattern acceleration/deceleration function and adjust the response time (inertial

moment setting) during vector control or switch to V/f control.

Combined with loads that have sharp fluctuations in rotation such as piston movements

In this case, adjust the response time (inertial moment setting) during vector control or switch to V/f

control.

Braking a motor when cutting off power supply

A motor with its power cut off goes into free-run, and does not stop immediately. To stop the motor

quickly as soon as the power is cut off install an auxiliary brake. There are different kinds of brake de-

vices, both electrical and mechanical. Select the brake that is best for the system.

Loads that generate negative torque

When combined with loads that generate negative torque the protection for overvoltage and overcurrent

on the inverter will go into operation and may cause a trip. For this kind of situation, you must install a

dynamic braking resistor, etc. that complies with the load conditions.

Motor with brake

If a motor with brake is connected directly to the output side of the inverter, the brake will not release

because voltage at startup is low. Wire the brake circuit separately from the motor's main circuits.

In circuit configuration 1, the brake is turned on and off through MC2 and MC3. If the circuit is config-

ured in some other way, the overcurrent trip may be activated because of the locked rotor current when

the brake goes into operation. Circuit configuration 2 uses low-speed signal RY to turn on and off the

brake. Turning the brake on and off with a low-speed signal may be better in such applications as ele-

vators. Please confer with us before designing the system.

1.4.2 Inverters

Protecting inverters from overcurrent

The inverter has an overcurrent protection function. However because the programmed current level is

set to the inverter's maximum applicable motor, if the motor is one of small capacity and it is in opera-

tion, the overcurrent level and the electronic thermal protection must be readjusted. If adjustment is

necessary, see 5-14 in Chapter 5, and make adjustments as directed.

Inverter capacity

Do not operate a large capacity motor with a small capacity (kVA) inverter even with light loads. Current

ripple will raise the output peak current making it easier to set off the overcurrent trip.

Power factor improving capacitors

Power factor improving capacitors cannot be installed on the output side of the inverter. When a motor

is run that has a power factor improving capacitor attached to it, remove the capacitors. This can cause

inverter malfunction trips and capacitor destruction.

Operating at other than rated voltage

Connections to voltages other than the rated voltage described in the rating label cannot be made. If a

connection must be made to a power supply other than one with rated voltage, use a transformer to

raise or lower the voltage to the rated voltage.

There is no fuse in the inverter's main circuit. Thus, as the diagram above shows, when more than one

inverter is used on the same power line, you must select interrupting characteristics so that only the

MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1). When you can-

not select the proper characteristics install a circuit interrupting fuse between the MCCB2 and the INV1.

■Disposal

If an inverter is no longer usable, dispose of it as industrial waste.

1.4.3 What to do about leak current

Warning

Current may leak through the inverter's input/output wires because of insufficient electrostatic capacity on the motor with

bad effects on peripheral equipment. The leak current's value is affected by the carrier frequency and the length of the in-

put/output wires. Test and adopt the following remedies against leak current.

(1)Effects of leak current across ground

Leak current may flow not just through the inverter system but also through ground wires to other sys-

tems. Leak current will cause earth leakage breakers, leak current relays, ground relays, fire alarms

and sensors to operate improperly, and it will cause superimposed noise on the CRT screen or display

of incorrect current amounts during current detection with the CT.

Remedies:

1.Reduce PWM carrier frequency.

The setting of PWM carrier frequency is done with the parameter .

2.Use high frequency remedial products (Schneider Toshiba electric corporation: Esper Mighty

Series) for earth leakage breakers. If you use equipment like this, there is no need to reduce

the PWM carrier frequency.

3.If the sensors and CRT are affected, it can be remedied using the reduction of PWM carrier

frequency described in 1 above, but if this cannot be remedied since there is an increase in the

motor's magnetic noise, please consult with Toshiba.

(2)Effects of leak current across lines

Power

supply

Thermal relay

Leak current path across wires

Inverter

(1) Thermal relays

The high frequency component of current leaking into electrostatic capacity between inverter out-

put wires will increase the effective current values and make externally connected thermal relays

operate improperly. If the wires are more than 50 meters long, it will be easy for the external ther-

mal relay to operate improperly with models having motors of low rated current (several

A(ampere) or less), especially the 400V class low capacity (3.7kW) models, because the leak cur-

rent will increase in proportion to the motor rating.

E6580757

A-15

Remedies:

1.Use the electronic thermal built into the inverter.

The setting of the electronic thermal is done using parameter , ( ).

2.Reduce the inverter's PWM carrier frequency. However, that will increase the motor's magnetic

noise. Use parameter for setting the PWM carrier frequency.

3.This can be improved by installing 0.1µ~0.5µF-1000V film capacitor to the input/output terminals of

each phase in the thermal relay.

Thermal relay

(2) CT and ammeter

If a CT and ammeter are connected externally to detect inverter output current, the leak current's high

frequency component may destroy the ammeter. If the wires are more than 50 meters long, it will be

easy for the high frequency component to pass through the externally connected CT and be superim-

posed on and burn the ammeter with models having motors of low rated current (several A(ampere) or

less), especially the 400V class low capacity (3.7kW or less) models, because the leak current will in-

crease in proportion to the motor's rated current.

Remedies:

1.Use a meter output terminal in the inverter control circuit.

The output current can be output on the meter output terminal (FM). If the meter is connected, use

an ammeter of 1mAdc full scale or a voltmeter of 7.5V-1mA full scale.

2.Use the monitor functions built into the inverter.

Use the monitor functions on the panel built into the inverter to check current values.

1.4.4 Installation

■Installation environment

The VF-S9 Inverter is an electronic control instrument. Take full consideration to installing it in the proper

operating environment.

Danger

Prohibited

•Do not place any inflammable substances near the VF-S9 Inverter. If an accident occurs in which flame

is emitted, this could lead to fire.

Mandatory

•Operate under the environmental conditions prescribed in the instruction manual.

Operations under any other conditions may result in malfunction.

Warning

Prohibited

•Do not install the VF-S9 Inverter in any location subject to large amounts of vibration.

This could cause the unit to fall, resulting in bodily injury.

Mandatory

•Check to make sure that the input power voltage is +10%, -15% of the rated power voltage written on

the rating label (±10% when the load is 100% in continuous operation)

If the input power voltage is not +10%, -15% of the rated power voltage (±10% when the load is 100%

in continuous operation) this may result in fire.

Warning

Prohibited

•Avoid operation in any location where there is direct spraying of the following solvents or other chemi-

cals. The plastic parts may be damaged to a certain degree depending on their shape, and there is a

possibility of the plastic covers coming off and the plastic units being dropped.

If the chemical or solvent is anything other than those shown below, please contact us in advance.

■How to install

Danger

Prohibited

•Do not install and operate the inverter if it is damaged or any component is missing.

This can result in electric shock or fire. Please consult your local agency for repairs.

Mandatory

•Must be installed in nonflammables such as metals.

The rear panel gets very hot so that if installation is in an inflammable object, this can result in fire.

•Do not operate with the front panel cover removed. This can result in electric shock.

•An emergency stop device must be installed that fits with system specifications (e.g. cuts off input

power then engages mechanical brakes).

Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury.

•All options used must be those specified by Toshiba. The use of any other option may result in an acci-

dent.

Warning

Mandatory

•The main unit must be installed on a base that can bear the unit's weight.

If the unit is installed on a base that cannot withstand that weight, the unit may fall resulting in injury.

•If braking is necessary (to hold motor shaft), install a mechanical brake. The brake on the inverter will

not function as a mechanical hold, and if used for that purpose, injury may result.

■Installation location

Select a location with good indoor ventilation, place lengthwise in the vertical direction and attach to a metal

wall surface.

If you are installing more than one inverter, the separation between inverters should be at least 5 centime-

ters, and they should be arranged in horizontal rows.

If the inverters are horizontally arranged with no space between them (side-by-side installation), peel of the

ventilation seals on top of the inverters and operate at 40°C or less (model of 3.7kW or less). Operate at

50°C or less (model of 5.5kW or more).

Note: Do not install in any location where there is high humidity or high temperatures and where there are

large amounts of dust, metallic fragments and oil mist. If you are going to install the equipment in any

area that presents a potential problem, please consult with Toshiba before doing so.

■Calorific values of the inverter and the required ventilation

The energy loss when the inverter converts power from AC to DC and then back to AC is about 5 percent. In

order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the interior of

the cabinet must be ventilated and cooled.

The amount of forcible air cooling ventilation required and the necessary heat discharge surface quantity

when operating in a sealed cabinet according to motor capacity are as follows.

■Panel designing taking into consideration the effects of noise.

The inverter generates high frequency noise. When designing the control panel setup, consideration must be

given to that noise. Examples of measures are given below.

•Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the

same conduit, do not run them parallel, and do not bundle them.

•Provide shielding and twisted wire for control circuit wiring.

•Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same

conduit, do not run them parallel, and do not bundle them.

•Ground the inverter ground terminals ( ).

E6580757

A-20

•Install surge suppressor on any magnetic contactor and relay coils used around the inverter.

•Install noise filters if necessary.

•Install EMC plate (attached as standard) and shielded wires fit with the EMC plate.

EMC plate

■Installing more than one unit in a cabinet

If you are installing two or more inverters in one cabinet, pay attention to the following.

•Ensure a space of at least 5 centimeters on the left and right sides of the inverters.

* If the inverters are horizontally arranged with no space between them (side-by-side installation), re-

move the ventilation seals on top of the inverters and operate at 40°C or less (model of 3.7kW or less)

or 50°C (model of 5.5kW or more).

•Ensure a space of at least 20 centimeters on the top and bottom of the inverters.

•Install an air deflecting plate so that the heat rising up from the inverter on the bottom does not affect the

inverter on the top.

2. Connection equipment

Danger

Disassembly

prohibited

•Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call

your sales agency.

Prohibited

•Don’t stick your fingers into openings such as cable wiring hole and cooling fan covers. This can result

in electric shock or other injury.

•Don't place or insert any kind of object into the inverter (electrical wire cuttings, rods, wires). This can

result in electric shock or fire.

•Do not allow water or any other fluid to come in contact with the inverter. That may result in electric

shock or fire.

Warning

Prohibited

•When transporting or carrying, do not hold by the front panel covers.

The covers may come off and the unit will drop out resulting in injury.

2.1 Cautions on wiring

Danger

Prohibited

•Never remove the front cover when power is on or open door if enclosed in a cabinet.

The unit contains many high voltage parts and contact with them will result in electric shock.

Mandatory

•Turn power on only after attaching the front cover or closing door if enclosed in a cabinet.

If power is turned on without the front cover attached or closing door if enclosed in a cabinet. This can

result in electric shock or other injury.

•Electrical construction work must be done by a qualified expert.

Connection of input power by someone who does not have that expert knowledge may result in fire or

electric shock.

•Connect output terminals (motor side) correctly.

If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury.

•Wiring must be done after installation.

If wiring is done prior to installation that may result in injury or electric shock.

•The following steps must be performed before wiring.

(1) Shut off all input power.

(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.

(3) Use a tester that can measure DC voltage (800VDC or more), and check to make sure that the

voltage to the DC main circuits (across PA-PC) is 45V or less.

If these steps are not properly performed, the wiring will cause electric shock.

•Tighten the screws on the terminal board to specified torque.

If the screws are not tightened to the specified torque, it may lead to fire.

E6580757

B-2

Danger

Be Grounded

•Ground must be connected securely.

If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or cur-

rent leak occurs.

Warning

Prohibited

•Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output

(motor side) terminal.

This could cause a fire.

■Preventing radio noise

To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's power

terminals (R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).

■Control and main power supply

The control power supply and the main circuit power supply for the VFS9 are the same.

If a malfunction or trip causes the main circuit to be shut off, control power will also be shut off. When

checking the cause of the malfunction or the trip, use the trip holding retention selection parameter.

■Wiring

•Because the space between the main circuit terminals is small use sleeved pressure terminals for the

connections. Connect the terminals so that adjacent terminals do not touch each other.

•For ground terminal use wires of the size that is equivalent to or larger than those given in table 10.1

and always ground the inverter (200V voltage class: D type ground [former type 3 ground]; 400V class: C

type ground [former special type 3 ground]).

Use as large and short a ground wire as possible and wire it as close as possible to the inverter.

•See the table in 9-1 for wire sizes.

•The length of the main circuit wire in 10-1 should be no longer than 30 meters. If the wire is longer than

30 meters, the wire size (diameter) must be increased.

E6580757

B-3

2.2 Standard connections

Danger

Prohibited

•Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3). Connecting input

power to the output could destroy the inverter or cause a fire.

•Do not connect resistors to DC terminals (across PA-PC or across PO-PC).

It could cause a fire.

Connect resistors as directed in the instructions for "Installing separate braking resistors."

•First shut off input power and wait at least 10 minutes before touching wires on equipment (MCCB) that

is connected to inverter power side.

Touching the wires before that time could result in electric shock.

Always connect

to ground

•Securely connect to ground with a ground wire.

If a secure connection to ground is not made, this could cause electric shock or fire when a malfunction

or leak current occurs.

■Sink logic (negative common)/source logic (positive common)

logic switching of input output terminals

Current flowing out turns control input terminals on. These are called sink logic terminals (The end of Type

- form : AN / WN). The general used method in Europe is source logic in which current flowing into the in-

put terminal turns it on(The end of Type - form : WP).

■Logic switching/voltage-current output switching (jumper)

(1) Logic switching

JP301 : Input, JP301A : Output

Switch logic before wiring to inverter and without supplying power. If sink and source are switched when

power is supplied first after logic switching or while power is being input to the inverter, that will destroy

the inverter. First check to make sure that switching is correct and then supply power.

(2) Voltage-current output switching

3. Operations

Danger

Prohibited

•Do not touch inverter terminals when electrical power is connected to the inverter even if the motor is

stopped.

Touching the inverter terminals while power is connected to it may result in electric shock.

•Do not touch switches when the hands are wet and do not try to clean the inverter with a damp cloth.

Such practices may result in electric shock.

•Do not go near the motor in alarm-stop status when the retry function is selected.

The motor may suddenly restart and that could result in injury.

Take measures for safety, e.g. attaching a cover to the motor, against accidents when the motor unex-

pectedly restarts.

Mandatory

•Turn power on only after attaching the front cover or closing door if enclosed in a cabinet.

If power is turned on without the front cover attached or closing door if enclosed in a cabinet, that may

result in electric shock or other injury.

•If the inverter begins to emit smoke or an unusual odor, or unusual sounds, immediately turn power off.

If the equipment is continued in operation in such a state, the result may be fire. Call your local sales

agency for repairs.

•Always turn power off if the inverter is not used for long periods of time.

•Turn input power on after attaching the front cover.

When enclosed inside a cabinet and using with the front cover removed, always close the cabinet

doors first and then turn power on. If the power is turned on with the front cover or the cabinet doors

open, it may result in electric shock.

•Make sure that operation signals are off before resetting the inverter after malfunction.

If the inverter is reset before turning off the operating signal, the motor may restart suddenly causing

injury.

Warning

Contact

prohibited

•Do not touch heat radiating fins or discharge resisters. These device are hot, and you'll get burned if

you touch them.

Prohibited

•Always observe the permissible operating ranges of motors and other equipment (see the instruction

manual for the motor).

If these ranges are not observed, it could result in injury.

4. Basic VF-S9 operations

The VF-S9 has the following three monitor modes.

Standard monitor mode : The standard inverter mode. This mode is enabled when

inverter power goes on.

This mode is for monitoring the output frequency and setting the frequency desig-

nated value. In it is also displayed information about status alarms during running and

trips.

•Setting frequency designated values - see 3.2.2

•Status alarm

If there is an error in the inverter, the alarm signal and the frequency will flash

alternately in the LED display.

: When a current flows at or higher than the overcurrent stall level.

: When a voltage is generated at or higher than the over voltage stall

level.

: When a load reaches 50% or higher of the overload trip value.

: When temperature inside the inverter rises to the overheating protec-

tion alarm level.

Model of 3.7kW or less : about 115°C.

Model of 5.5kW or more : about 92°C

Setting monitor mode : The mode for setting inverter parameters.

For more on how to set parameters, see 4.1.

Status monitor mode : The mode for monitoring all inverter status.

Allows monitoring of set frequencies, output current/voltage and terminal

information.

For more on how to use the monitor, see 8.1.

Pressing the key will move the inverter through each of the modes.

4.1 How to set parameters Setting monitor mode

The standard default parameters are programmed before the unit is shipped from the factory. Parameters can be

divided into three major categories. Select the parameter to be changed or to be searched and retrieved.

Basic parameters : The basic parameters that must be programmed be-

fore the first use.

Extended parameters : The parameters for detailed and special setting.

User parameters

(automatic edit function)

: Indicates parameters that are different from the stan-

dard default setting parameters. Use them to check

after setting and to change setting.

(Parameter title: )

Setup parameters : When the standard setting is entered, this

parameter is displayed.

* Adjustment range of parameters

: An attempt has been made to assign a value that is higher than the programmable range. Or, as a

result of changing other parameters, the programmed value of the parameter that is now selected

exceeds the upper limit.

: An attempt has been made to assign a value that is lower than the programmable range. Or, as a

result of changing other parameters, the programmed value of the parameter that is now selected

exceeds the lower limit.

If the above alarm is flashing on and off, no setting can be done of values that are equal to or greater

than or equal to or lower than .

While these codes are flashing on and off, no change can be made to any parameter.

5. Basic parameters

Before you operate the inverter, the parameters that you must first program are the basic parameters.

5.1 Setting acceleration/deceleration time

: Automatic acceleration/deceleration

: Acceleration time 1

: Deceleration time 1

•Function

1) For acceleration time , program the time that it takes for the inverter output frequency to go from

0Hz to maximum frequency .

2) For deceleration time , program the time that it takes for the inverter output frequency to go from

maximum frequency to 0Hz.

5.1.1 Automatic acceleration/deceleration

This automatically adjusts acceleration and deceleration time in line with load size.

* Automatically adjusts acceleration and deceleration time within the inverter rated current in a range that

goes from 1/8 to infinity of programmed and time. It goes to the optimum value taking a mar-

ginal allowance into consideration.

* Automatically adjusts to the shortest time within 120% of the inverter rated current. It is a value that is ob-

tained attaching importance to acceleration/deceleration time.

✩When automatically setting acceleration/deceleration time, always change the acceleration/deceleration

time so that it conforms with the load. For inverters that requires a fixed acceleration/deceleration time, use

the manual settings ( , ).

✩Setting acceleration/deceleration time ( , ) in conformance with mean load allows optimum

setting that conforms to further changes in load.

✩Use this parameter after actually connecting the motor.

✩Acceleration may not be complete if the load is such that the inverter is operated in the rated current vicin-

ity. If acceleration is incomplete, set acceleration/deceleration time manually ( ).

✩If the programmed value is shorter than the optimum acceleration/deceleration time determined by load

conditions, overcurrent stall or overvoltage stall function may make the acceleration/deceleration time

longer than the programmed time. If an even shorter acceleration/deceleration time is programmed, there

may be an overcurrent trip or overvoltage trip for inverter protection. (for further details, see 13.1).

5.2 Increasing starting torque

: Automatic torque boost

•Function

Simultaneously switches inverter output (V/F) control and programs motor constants automatically (On-

line automatic-tuning function) to improve torque generated by the motor. This parameter integrates the

setting of special V/F control selection such as vector control.

Title Function Adjustment range Default setting

Automatic torque boost 0: Disabled

Note:Parameter displays on the right always return to 0 after setting. The pervious setting is displayed on the left.

Ex.

1) When using vector control (increasing starting torque and high-precision opera-

tions)

Set the automatic control to (sensorless vector control + auto-tuning)

Setting automatic control to (sensorless vector control + auto-tuning) provides high starting torque

bringing out the maximum in motor characteristics from the low-speed range. This suppresses changes in

motor speed caused by fluctuations in load to provide high precision operation. This is an optimum feature for

elevators and other load transporting machinery.

ride-through control after momentary power failure, supply voltage correction, acceleration/deceleration S-

pattern).

This parameter is especially suitable for wind force or hydraulic machinery such as fans and pumps

★Motor constant must be set

If the motor you are using is a 4P Toshiba standard motor and if it has the same capacity as the inverter,

there is basically no need to set the motor constant.

There are two procedures for setting the motor constant.

1) The motor constant can be set automatically (auto-tuning). Program the extended parameter

to .⇒ For details, see selection 2 in 6.13.

2) Each motor constant can be set individually. ⇒ For details, see selection 3 in 6.13.

4) Sensorless vector control--increasing starting torque and achieving high-precision

operation.

Setting of V/F control mode selection to (Sensorless vector control)

Using sensorless vector control with a Toshiba standard motor will provide the highest torque at the lowest

speed ranges. The effects obtained through the use of sensorless vector control are described below.

(1) Provides large starting torque.

(2) Effective when stable operation is required to move smoothly up from the lowest speeds.

(3) Effective in elimination of load fluctuations caused by motor slippage.

★Motor constant must be set

If the motor you are using is a 4P Toshiba standard motor and if it has the same capacity as the inverter,

there is basically no need to set the motor constant.

There are three procedures for setting motor constants.

1) The sensorless vector control and motor constants (auto-tuning) can be set at a time.

Set the basic parameter to . ⇒ For details, see 1 in 5.2.

2) The motor constant can be automatically set (auto-tuning).

3) Each motor constant can be set individually. ⇒ For details, see selection 3 in 6.13.

5) Energy-saving

Setting V/F control mode selection to (automatic energy-saving)

Energy can be saved in all speed areas by detecting load current and flowing the optimum current that fits

the load.

★Motor constant must be set

The motor you are using is a 4P Toshiba standard motor and if it has the same capacity as the inverter, there

is basically no need to set the motor constant.

There are two procedures for setting the motor constant.

⇒ For details, see selection 2 in 6.13.

2) Each motor constant can be set individually. ⇒ For details, see selection 3 in 6.13.

6) Precautions on vector control

1) The sensorless vector control exerts its characteristics effectively in frequency areas below the base fre-

quency ( ). The same characteristics will not be obtained in areas above the base frequency.

2) Set the base frequency to anywhere from 40 to 120Hz during sensorless vector control ( ).

3) Use a general purpose squirrel-cage motor with a capacity that is the same as the inverter's rated capac-

ity or one rank below.

The minimum applicable motor capacity is 0.1kW.

4) Use a motor that has 2~8 P.

5) Always operate the motor in single operation (one inverter to one motor). Sensorless vector control can-

not be used when one inverter is operated with more than one motor.

6) The maximum length of wires between the inverter and motor is 30 meters. If the wires are longer than

30 meters, set standard auto-tuning with the wires connected to improve low-speed torque during sen-

sorless vector control.

However the effects of voltage drop cause motor-generated torque in the vicinity of rated frequency to be

somewhat lower.

7) Connecting a reactor or surge voltage suppression filter between the inverter and the motor may reduce

motor-generated torque. Setting auto-tuning may also cause a trip ( ) rendering sensorless vector

control unusable.

1) Setting the electronic thermal protection characteristics selection and

motor electronic thermal protection level 1

The electronic thermal protection characteristics selection is used to enable or disable the motor

overload trip function ( ) and the overload stall function.

While the inverter overload trip ( ) will be in constant detect operation, the motor overload trip ( )

can be selected using the parameter .

Explanation of terms

Overload stall: When the inverter detects an overload, this function automatically lowers the output

frequency before the motor overload trip is activated. The soft stall function

allows the drive to run with balanced load current frequency without a trip. This is an

optimum function for equipment such as fans, pumps and blowers with variable

torque characteristics that the load current decreases as the operating speed de-

creases.

Note: Do not use the overload stall function with loads having constant torque characteristics (such as

conveyor belts in which load current is fixed with no relation to speed).

[Using standard motors (other than motors intended for use with inverters)]

When a motor is used in the lower frequency range than the rated frequency, that will decrease the cooling

effects for the motor. This speeds up the start of overload detection operations when a standard motor is

used in order to prevent overheating.

A VF motor (a motor for use with an inverter) can be used in lower frequency ranges than the general-

purpose motor, but if that frequency is extremely low, the effects of cooling on the motor will deteriorate.

■Setting the motor electronic thermal protection level 1

If the capacity of the motor being used is smaller than the capacity of the inverter, or the rated current of

the motor is smaller than the rated current of the inverter, adjust the electronic thermal protection level 1

•Function

1) The F300 parameter allows the tone of the magnetic noise from the motor to be changed by switching

the PWM carrier frequency. This parameter is also effective in preventing the motor from resonating

with its load machine or its fan cover.

2) In addition, the F300 parameter reduces the electromagnetic noise generated by the inverter. Reduce

the carrier frequency to reduce electromagnetic noise. Note: Although the electromagnetic noise level

is reduced, the magnetic noise of the motor is increased.

frequency. (Allowable operation frequency: 80Hz max.)

Caution

Mandatory

•Stand clear of motors and mechanical equipment

If the motor stops due to a momentary power failure, the equipment will start suddenly when power is

restored. This could result in unexpected injury.

•Attach warnings about sudden restart after a momentary power failure on inverters, motors and equip-

ment to prevent accidents in advance.

•Function

The F301 parameter detects the rotating speed and rotational direction of the motor during coasting

in the event of momentary power failure, and then after power has been restored, restarts the motor

smoothly (motor speed search function). This parameter also allows commercial power operation to

be switched to inverter operation without stopping the motor.

Application!!

•A waiting time of 200 to 1,000msec is preset to allow the residual voltage in the motor to decrease

to a certain level during restart. For this reason, the start-up takes more time than usual.

•Use this function when operating a system with one motor connected to one inverter. This function

may not operate properly in a system configuration with multiple motors connected to one inverter.

Application to a crane or hoist

The crane or hoist may have its load moved downward during the above waiting time from input of

the operation starting command to the restart of the motor. To apply the inverter to such machines,

therefore, set the auto-restart control mode selection parameter to "0" (Disabled), and avoid using

the retry function. If retry function is enabled the load could move downward causing damage and

or injury.

6.12.2 Regenerative power ride-through control

The motor may suddenly restart, which could result in injury.

•Take measures for safety, e.g. attach a cover to the motor, to prevent accidents if the motor suddenly re-

starts.

This parameter resets the inverter automatically when the inverter gives an alarm. During the retry

mode, the motor speed search function operates automatically as required and thus allows smooth

motor restarting.

trying is not successful within the speci-

fied number of times.

• : Arm overcurrent at start-up • : Main unit RAM fault

• : Overcurrent on the load side at start-up • : Main unit ROM fault

• : Output phase failure • : CPU fault trip

• : External thermal trip • : Remote control error

• : Small-current operation trip • : Auto-tuning error

• : External trip stop

• : Undervoltage trip (main circuit) • : Ground fault trip

• : Input phase failure • : Inverter type error

★Protective operation detection relay signals (FLA, FLB, FLC terminal signals) are not sent during use of

the retry function.

★A virtual cooling time is provided for overload tripping ( , , ). In this case, the retry func-

tion operates after the virtual cooling time and retry time.

the particular deviation (the difference between the set frequency and the feedback value) is obtained

by multiplying this deviation by the parameter setting.

: Motor primary constant

: Motor secondary constant

: Motor excitation constant

: Magnification of load inertial moment

: Rated capacity ratio of motor to inverter

To use vector control, automatic torque boost and automatic energy-saving, motor constant setting (motor tuning)

is required. The following three methods are available to set motor constants (for automatic torque boosting,

however, two methods are available):

1) Using the automatic torque boost ( ) for setting the V/F control mode selection

( ) and auto-tuning ( ) at the same time

2) Setting the V/F control mode selection ( ) and auto-tuning ( ) independently

3) Combining the V/F control mode selection ( ) and manual tuning

Sensorless vector control may not operate properly if the motor capacity differs from the applicable rated capacity

of the inverter by more than two grades.

[Selection 1: Setting by automatic torque boost]

This is the easiest of the available methods. It conducts vector control and auto-tuning at the same time.

Set to " ".

Set to " " if the motor capacity is one size smaller than the applicable rated capacity of the inverter.

✩Precautions on auto-tuning

(1) Conduct auto-tuning only after the motor has been connected and operation completely stopped.

If auto-tuning is conducted immediately after operation stops, the presence of a residual voltage

may result in abnormal tuning.

(2) Voltage is applied to the motor during tuning even though it barely rotates.

(3) Tuning is usually completed within three seconds. If it is aborted, the motor will trip with the dis-

play of " " and no constants will be set for that motor.

(4) High-speed motors, high-slip motors or other special motors cannot be auto-tuned. For these

motors, perform manual tuning using Selection 3 described below.

(5) Provide cranes and hoists with sufficient circuit protection such as mechanical braking. Without

sufficient circuit protection, the resulting insufficient motor torque during tuning could create a risk

of machine stalling/falling.

(6) If auto-tuning is impossible or an " " auto-tuning error is displayed, perform manual tuning

with Selection 3.

[Selection 3: Setting vector control and manual tuning independently]

If an " " tuning error is displayed during auto-tuning or when vector control characteristics are to be

improved, independent motor constants can be set.

Setting procedure

Adjust the following parameters:

: Select " " to set the motor constant independently using the ∼ parameters.

: Set the slip frequency for the motor. A higher slip frequency reduces motor slipping correspond-

ingly. (The slip frequency can be set on the basis of test records of the motor.)

: Adjust the primary resistive component of the motor. Decreases in torque due to a possible volt-

age drop during low-speed operation can be suppressed by setting a large value in this parameter.

(Perform adjustments according to the actual operation.)

: Adjust the secondary component of the motor. This parameter is enabled only when is

set to " ". A larger adjustment value gives more slip correction. (Perform adjustments according

to the actual operation.)

: Set the excitation inductance for the motor. A larger inductance creates a smaller no-load current.

(Perform adjustments according to the actual operation.)

: Set a load inertia moment with a multiple of the motor inertia moment. A transient response can

be adjusted. A larger adjustment value reduces inertial overshoot, and thus prevents the occur-

rence of an overcurrent and an overvoltage, correspondingly.

: Set "1" if the rated capacity of the motor is one size smaller than that of the inverter.

* Sensorless vector control may not operate properly if the motor capacity differs from the appli-

cable rated capacity of the inverter by more than two grades.

•Function

The VFS9 Series allows a data communication network to be constructed for exchanging data between

a host computer or controller (referred to collectively as the computer) and the inverter by connecting an

optional RS232C or RS485 communication conversion unit.

<Computer-linking functions>

The following functions are enabled by data communication between the computer and inverter

(1) Monitoring inverter status (such as the output frequency, current, and voltage)

(2) Sending RUN, STOP and other control commands to the inverter

(3) Reading, editing and writing inverter parameter settings

Data can be exchanged between one computer and one inverter.

Data can be exchanged between the computer and a maximum of 64 inverters.

✩The following are available as common serial optional units:

•RS232C communications conversion unit (Model: RS2001Z)

Communications cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)

•RS485 communication conversion unit with terminal board (Model: RS4001Z)

Communication cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)

■Setting the communication functions

Setting commands and frequencies by communications has priority over sending commands from the opera-

tion panel or the terminal board. Command/frequency setting by communications can therefore be enabled,

irrespective of the setting in the command mode ( ) or the frequency setting mode ( ).

However, when the input terminal function selection parameter is set to 48: SC/LC (Serial/Local selection),

the inverter can be operated with the settings of the command mode ( ) or the frequency setting mode

( ) by external input.

9. Taking measures to satisfy

the CE/UL directive

9.1 How to cope with the CE directive

In Europe, the EMC directive and the low-voltage directive, which took effect in 1996 and 1997, respectively,

make it obligatory to put the CE mark on every applicable product to prove that it complies with the directives.

Inverters do not work alone but are designed to be installed in a control panel and always used in combination

with other machines or systems which control them, so they themselves are not considered to be subject to the

EMC directive.

However, the CE mark must be put on all inverters because they are subject to the low-voltage directive.

The CE mark must be put on all machines and systems with built-in inverters because such machines and sys-

tems are subject to the above directives. If they are "final" products, they might also be subject to machine-

related directives. It is the responsibility of the manufacturers of such final products to put the CE mark on each

one. In order to make machines and systems with built-in inverters compliant with the EMC directive and the low-

voltage directive, this section explains how to install inverters and what measures should be taken to satisfy the

EMC directive.

We have tested representative models with them installed as described later in this manual to check for confor-

mity with the EMC directive. However, we cannot check all inverters for conformity because whether or not they

conform to the EMC direction depends on how they are installed and connected. In other words, the application

of the EMC directive varies depending on the composition of the control panel with a built-in inverter(s), the rela-

tionship with other built-in electrical components, the wiring condition, the layout condition, and so on. Therefore,

please verify yourself whether your machine or system conforms to the EMC directive.

9.1.1 About the EMC directive

The CE mark must be put on every final product that includes an inverter(s) and a motor(s). The VF-S9 series of

inverters complies with the EMC directive if an EMI filter recommended by Toshiba is connected to it and wiring is

carried out correctly.

■EMC directive 89/336/EEC

The EMC standards are broadly divided into two categories; immunity- and emission-related standards, each of

which is further categorized according to the operating environment of each individual machine. Since inverters

are intended for use with industrial systems under industrial environments, they fall within the EMC categories

listed in Table 1 below. The tests required for machines and systems as final products are almost the same as

those required for inverters.

9.1.2 Measures to satisfy the EMC directive

This subsection explains what measures must be taken to satisfy the EMC directive.

(1) Insert a recommended EMI filter (Table 2) on the input side of the inverter to reduce radiation and transmis-

sion noises. In the combinations listed in Table 2, inverters were checked for conformity with the EMC di-

rective. For inverters used in Japan, it is recommended to use the NF series of noise filters.

Table 2 lists noise filters recommended for the inverters.

(2) Use shielded cables for the power and control cables, including filter input cables and inverter output ca-

bles. Route the cables and wires so as to minimize their lengths. Keep a distance between the power ca-

ble and the control cable and between the input and output wires of the power cable. Do not route them in

parallel or bind them together, instead cross at right angle.

(3) Install the inverter and the filter on the same metal plate. It is more effective in limiting the radiation noise to

install the inverter in a sealed steel cabinet. Using wires as thick and short as possible, earth the metal

plate and the control panel securely with a distance kept between the earth cable and the power cable.

(4) Route the EMI filter input and output wires apart from each other.

(5) To limit the radiation noise from cables, earth each shielded cable to the metal plate. It is effective to earth

shielded cables in the vicinity of the inverter, cabinet and filter (within a radius of 10cm from each of them).

Inserting a ferrite core in a shielded cable is even more effective in limiting the radiation noise.

(6) To further limit the radiation noise, insert a zero-phase reactor in the inverter output line and insert ferrite

cores in the earth cables of the metal plate and cabinet.

9.1.3 About the low-voltage directive

The low-voltage directive provides for the safety of machines and systems. All Toshiba inverters are CE-marked

in accordance with the standard EN 50178 specified by the low-voltage directive, and can therefore be installed in

machines or systems and imported without problem to European countries.

Applicable standard: EN 50178

Electronic equipment for use in power installations

Pollution level: 2 (5.2.15.2)

Overvoltage category: 3

200V class - 3.0mm (5.2.16.1)

400V class - 5.5mm (5.2.16.1)

EN 50178 applies to electrical equipment intended specially for use in power installations, and sets out the condi-

tions to be observed for electric shock prevention when designing, testing, manufacturing and installing electronic

equipment for use in power installations.

9.1.4 Measures to satisfy the low-voltage directive

When incorporating the inverter into a machine or system, it is necessary to take the following measures so that

the inverter satisfies the low-voltage directive.

(1) When installing the inverter outside the cabinet, provide a protective means for the inverter's wiring hole to

prevent workers from putting their fingers through the hole and touching an electrically-charged part in the

inverter.

(2) Do not connect two or more wires to the main circuit earth terminal of the inverter. If necessary, install an

additional earth terminal on the metal plate on which the inverter is installed and connect another cable to it.

Or install the EMC plate (attached as standard) and another cable connect to earth terminal on the EMC

plate. Refer to the table 10.1 for earth cable sizes.

(3) Install a non-fuse circuit breaker on the input side of the inverter.

10. Peripheral devices

Danger

Mandatory

•When using switchgear for the inverter, it must be installed in a cabinet.

Failure to do so can lead to risk of electric shock and can result in death or serious injury.

Be Grounded

•Connect earth cables securely. Failure to do so can lead to risk of electric shock or fire in case of a

failure, short-circuit or leak current.

10.2 Installation of a magnetic contactor

If using the inverter without installing a magnetic contactor (MC) in the primary circuit, use an MCCB (with a

power cutoff device) to open the primary circuit when the inverter protective circuit is activated.

If using a braking resistor or braking resistor unit, install a magnetic contactor (MC) or non-fuse circuit breaker

with a power cutoff device to the power supply of the inverter, so that the power circuit opens when the failure

detection relay (FL) in the inverter or the external overload relay is activated.

■Magnetic contactor in the primary circuit

A magnetic contactor installed in the power supply circuit of the inverter cuts off the power supply to the cir-

cuit and prevents the inverter from restarting in case of a power failure, a trip of the overload relay (Th-Ry)

or the activation of the inverter protective circuit.

In addition, if the FL contact of the failure detection relay in the VF-S9 is connected to the operation circuit

of the magnetic contactor on the primary side, the magnetic contactor (MC) will be tripped when the inverter

protective circuit is activated.

Example of connection of a magnetic contactor in the primary circuit

Notes on wiring

•When frequently switching between start and stop, do not use the magnetic contactor on the primary side as

an on-off switch for the inverter. Instead, stop and start the inverter by using terminals F and CC (forward run)

or R and CC (reverse run).

•Be sure to attach a surge killer to the exciting coil of the magnetic contactor (MC).

■Magnetic contactor in the secondary circuit

A magnetic contactor may be installed on the secondary side to switch controlled motors or supply com-

mercial power to the load when the inverter is out of operation.

Notes on wiring

•Be sure to interlock the magnetic contactor on the secondary side with the power supply to prevent commercial

power from being applied to the inverter output terminals.

•When installing a magnetic contactor (MC) between the inverter and the motor, avoid turning the magnetic

contactor on or off during operation. Turning the magnetic contactor on or off during operation causes a cur-

rent to rush into the inverter which could lead to malfunction.

10.3 Installation of an overload relay

1) The VF-S9 inverter has an electronic-thermal overload protective function. In the following cases, however,

the activation level of the electronic thermal protection unit must be adjusted and an overload relay suitable

for the motor installed between the inverter and the motor.

•When using a motor with a current rating different to that of the corresponding Toshiba general-purpose

motor

•When operating a single motor with an output smaller than that of the applicable standard motor or more

than one motor simultaneously

2) When using the VF-S9 inverter to operate a constant-torque motor, such as the Toshiba VF motor, adjust

the protection characteristic of the electronic thermal protection unit to the VF motor use.

3) It is recommended to use a motor with a thermal relay embedded in the motor coil to give sufficient protec-

tion to the motor, especially when it runs in a low-speed range.

Optional external devices

No. Device Function and purpose

(1)

Input AC reactor Used to improve the input power factor, reduce the harmonics, and suppress external

surge on the inverter power source side. Install when the power capacity is 500 kVA or

more and 10 times or more than the inverter capacity or when a distorted wave genera-

tion source such as a thyristor unit or a large-capacity inverter is connected in the same

distribution system.

{ Large : Large effective. { : effective. × : ineffective

(2)

DC reactor Improves the power factor more than the input reactor. When the facility applying the

inverter requires high reliability, it is recommended to use the DC reactor with an input re-

actor effective for external surge suppression.

* An inverter unit of 200V-3.7kW or less is connected to a reactor selected on page J-8, 9

to conform “Guides of limits for harmonics current emissions on general purpose

inverter having an input current up to and including 20A per phase” by the Japan Elec-

trical Manufacturers’ Association.

(3)

These types of filters are not necessary because all single-phase 200V or 3-phase 400V

models and 3-phase 200V, 5.5kW or 7.5kW models have a built-in EMI noise filter, con-

forming to Class A, as standard. But install these filters if necessarily of noise reduction

move and more.

•Effective to prevent interference in audio equipment used near the inverter.

•Install on the input side of the inverter.

•Provided with wide-range attenuation characteristics from AM radio bands to near

10MHz.

•Use when equipment readily affected by noise is installed in the peripheral area.

13.2 Restoring the inverter from a trip

Do not reset the inverter when tripped because of a failure or error before eliminating the cause. Resetting the

tripped inverter before eliminating the problem causes it to trip again.

The inverter can be restored from a trip by any of the following operations:

(1) By turning off the power (Keep the inverter off until the LED turns off.)

Note) Refer to 6.15.3 (inverter trip retention selection ) for details.

(2) By means of an external signal (Short-circuiting of control terminals RST and CC)

(3) By operation panel operation

(4) By inputting a trip clear signal from a remote input device

(Refer to the remote input device operating manual for details.)

To reset the inverter by operation panel operation, follow these steps.

1. Press the STOP key and make sure that is displayed.

2. Pressing the STOP key again will reset the inverter if the cause of the trip has already been elimi-

nated.

✩When any overload function [ : inverter overload, : motor overload, : braking re-

sistor overload] is active, the inverter cannot be reset by inputting a reset signal from an external de-

vice or by operation panel operation before the virtual cooling time has passed.

Virtual cooling time ... : about 30 seconds after the occurrence of a trip

: about 120 seconds after the occurrence of a trip

: about 20 seconds after the occurrence of a trip

✩In the case of a trip due to overheating ( ), the inverter checks the temperature within. Wait until

the temperature in the inverter falls sufficiently before resetting the inverter.

[Caution]

Turning the inverter off then turning it on again resets the inverter immediately. You can use this mode of re-

setting if there is a need to reset the inverter immediately. Note, however, that this operation may damage the

system or the motor if it is repeated frequently.

13.4 How to determine the causes of other problems

The following table provides a listing of other problems, their possible causes and remedies.

Problems Causes and remedies

The motor runs in the

wrong direction. •Invert the phases of the output terminals U, V and W.

•Invert the forward/reverse run-signal terminals of the external input device. (See

6.3 "Assignment of functions to control terminals".)

The motor runs but its

speed does not change

normally.

•The load is too heavy.

Reduce the load.

•The soft stall function is activated.

Disable the soft stall function. (See 5.14.)

•The maximum frequency and the upper limit frequency are set too low.

Increase the maximum frequency and the upper limit frequency .

•The frequency setting signal is too low.

Check the signal set value, circuit, cables, etc.

•Check the setting characteristics (point 1 and point 2 settings) of the frequency

setting signal parameters. (See 6.5.)

•If the motor runs at a low speed, check to see that the stall prevention function is

activated because the torque boost amount is too large.

Adjust the torque boost amount ( ) and the acceleration time ( ). (See

5.12 and 5.1.)

The motor does not ac-

celerate or decelerate

smoothly.

•The acceleration time ( ) or the deceleration time ( ) is set too short.

Increase the acceleration time ( ) or the deceleration time ( ).

A too large current flows

into the motor. •The load is too heavy.

Reduce the load.

•If the motor runs at a low speed, check whether the torque boost amount is too

large. (See 5.13.)

The motor runs at a

higher or lower speed

than the specified one.

•The motor has an improper voltage rating.

Use a motor with a proper voltage rating.

•The motor terminal voltage is too low.

Check the setting of the base frequency voltage parameter ( ). (See

6.12.6.)

Replace the cable with a cable larger in diameter.

•The reduction gear ratio, etc., are not set properly.

Adjust the reduction gear ratio, etc.

•The output frequency is not set correctly.

Check the output frequency range.

•Adjust the base frequency. (See 5.11.)

The motor speed fluctu-

ates during operation. •The load is too heavy or too light.

Reduce the load fluctuation.

•The inverter or motor used does not have a rating large enough to drive the

load.

Use an inverter or motor with a rating large enough.

•Check whether the frequency setting signal changes.

•If the V/F control selection parameter is set at 3, check the vector control

setting, operation conditions, etc. (See 5.12.)

Parameter settings can-

not be changed. •Change the setting of the parameter (prohibition of change of parameter

setting) to (permitted) if it is set at (prohibited).

For reasons of safety, some parameters cannot be reprogrammed while the

inverter is running.

14. Inspection and maintenance

Danger

Mandatory

•The equipment must be inspected every day.

If the equipment is not inspected and maintained, errors and malfunctions may not be discovered

which could lead to accidents.

•Before inspection, perform the following steps.

(1) Shut off all input power to the inverter.

(2) Wait for at least ten minutes and check that the charge lamp is no longer lit.

(3) Use a tester that can measure DC voltages (800V DC or more), and check that the voltage to the

DC main circuits (across PA-PC) does not exceed 45V.

Performing an inspection without carrying out these steps first could lead to electric shock.

•When using switchgear for the inverter, it must be installed in a cabinet.

Failure to do so can lead to risk of electric shock and can result in death or serious injury.

Be sure to inspect the inverter regularly and periodically to prevent it from breaking down because of the environment

of use, such as temperature, humidity, dust and vibration, or deterioration of its components with aging.

14.1 Regular inspection

Since electronic parts are susceptible to heat, install the inverter in a cool, well-ventilated and dust-free place.

This is essential for increasing the service life.

The purpose of regular inspections is to maintain the correct environment of use and to find any sign of failure or

malfunction by comparing current operation data with past operation records.

3. Unusual vibration or noise

4. Overheating or discoloration

5. Unusual odor

6. Unusual motor vibration, noise or overheating

14.2 Periodical inspection

Make a periodical inspection at intervals of 3 or 6 months depending on the operating conditions.

Danger

Mandatory

• Before inspection, perform the following steps.

(1) Shut off all input power to the inverter.

(2) Wait for at least ten minutes and check that the charge lamp is no longer lit.

(3) Use a tester that can measure DC voltages (800V DC or more), and check that the voltage to the

DC main circuits (across PA-PC) does not exceed 45V.

Performing an inspection without carrying out these steps first could lead to electric shock.

Prohibited

• Never replace any part. This could be a cause of electric shock, fire or bodily injury. To replace parts,

call the local sales agency.

■Check items

1. Check to see if all screwed terminals are tightened firmly. If any screw is found loose, tighten it again

with a screwdriver.

2. Check to see if all crimped terminals are fixed properly. Check them visually to see that there is no trace

of overheating around any of them.

3. Check visually all cables and wires for damage.

4. With a vacuum cleaner, remove dirt and dust, especially from the vents and the printed circuit boards.

Always keep them clean to prevent an accident due to dirt or dust.

5. When leaving the inverter unused for a long time, check it for functioning once every 2 years or so by

supplying it with electricity for at least 5 hours with the motor disconnected. It is advisable not to supply

the commercial power directly to the inverter but to gradually increase the power supply voltage with a

transformer.

6. If the need arises, conduct an insulation test on the main circuit terminal board only, using a 500V insu-

lation tester. Never conduct an insulation test on control terminals other than terminals on the printed

circuit board or on control terminals. When testing the motor for insulation performance, separate it from

the inverter in advance by disconnecting the cables from the inverter output terminals U, V and W.

When conducting an insulation test on peripheral circuits other than the motor circuit, disconnect all ca-

bles from the inverter so that no voltage is applied to the inverter during the test.

E6580757

N-3

(Note) Before an insulation test, always disconnect all cables from the main circuit terminal board

and test the inverter separately from other equipment.

500V insulation tester

(megger)

7. Never test the inverter for pressure. A pressure test may cause damage to its components.

8. Voltage and temperature check

Recommended voltmeter:

Input side ... Moving-iron type voltmeter ( )

Output side ... Rectifier type voltmeter ( )

It will be very helpful for detecting a defect if you always measure and record the ambient temperature

before, during and after the operation.

■Replacement of expendable parts

The inverter is composed of a large number of electronic parts including semiconductor devices. The fol-

lowing parts deteriorate with the passage of time because of their composition or physical properties. The

use of aged or deteriorated parts leads to degradation in the performance or a breakdown of the inverter. To

avoid such trouble, the inverter should be checked periodically.

Note) Generally, the life of a part depends on the ambient temperature and the conditions of use. The life

spans listed below are applicable to parts when used under normal environmental conditions.

1) Cooling fan

The fan, which cools down heat-generating parts, has a service life of about 30,000 hours (about 2 or 3

years of continuous operation). The fan also needs to be replaced if it makes a noise or vibrates ab-

normally.

2) Smoothing capacitor

The smoothing aluminum electrolytic capacitor in the main circuit DC section degrades in performance

because of ripple currents, etc. It becomes necessary to replace the capacitor after it is used for about

5 years under normal conditions. If your inverter is intended for a 3.7kW or smaller motor, replace the

smoothing capacitor together with the printed circuit board on which it is mounted.

•Absence of liquid leak

•Safety valve in the depressed position

•Measurement of electrostatic capacitance and insulation resistance

E6580757

N-4

The operation time is helpful for roughly determining the time of replacement. For the replacement of parts,

contact the service network or Toshiba branch office printed on the back cover of this instruction manual.

■Standard replacement cycles of principal parts

The table below provides a listing of the replacement cycles of parts when used under normal conditions

(average ambient temperature: 30°C, load factor: not more than 80%, operation time: 12 hours per day).

The replacement cycle of each part does not mean its service life but the number of years over which its

failure rate does not increase significantly.

Part name Standard

replacement cycle Replacement mode and others

Cooling fan 2 to 3 years Replacement with a new one

Smoothing capacitor 5 years Replace with a new one (depending on the check results)

Circuit breaker and

relays - Whether to replace or not depends on the check results

Timer - Whether to replace or not depends on the operation time

Fuse 10 years Replacement with a new one

Aluminum capacitor

on printed circuit

board

5 years Replace with a new circuit board (depending on the

check results)

(Extract from "Guide to periodical inspections of general-purpose inverters" issued by the Japan Electric In-

dustries Association.)

Note) The life of a part greatly varies depending on the environment of use.

14.3 Making a call for servicing

For the Toshiba service network, refer to the back cover of this instruction manual. If defective conditions are en-

countered, please contact the Toshiba service section in charge via your Toshiba dealer.

When making a call for servicing, please inform us of the contents of the rating label on the right panel of the

inverter, the presence or absence of optional devices, etc., in addition to the details of the failure.

14.4 Keeping the inverter in storage

Take the following precautions when keeping the inverter in storage temporarily or for a long period of time.

1. Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder.

2. If the printed circuit board in your inverter has an anti-static cover (black cover), do not leave it detached

from the circuit board during storage, though the cover must be detached before turning on the inverter.

3. If no power is supplied to the inverter for a long time, the performance of its large-capacity electrolytic ca-

pacitor declines.

When leaving the inverter unused for a long time, supply it with electricity once every two years, for 5 hours

or more each, to recover the performance of the large-capacity electrolytic capacitor and also to check the

function of the inverter. It is advisable not to supply the commercial power directly to the inverter but to

gradually increase the power supply voltage with a transformer, etc.

16. Disposal of the inverter

Warning

Mandatory

•If you throw away the inverter, have it done by a specialist in industry waste disposal*.

If you throw away the inverter by yourself, this can result in explosion of capacitor or produce noxious

gases, resulting in injury.

(*) Persons who specialize in the processing of waste and known as "industrial waste product collectors

and transporters" or "industrial waste disposal persons."

If the collection, transport and disposal of industrial waste is done by someone who is not licensed for

that job, it is a punishable violation of the law. (laws in regard to cleaning and processing of waste

materials)
