■ Transportation  Installation Danger

• Do not install or operate the inverter if it is damaged or any component is missing. This can result in electric shock or fire. Please consult your local sales agency for repairs.

• Do not place any inflammable objects nearby.

Prohibited

Mandatory

If a flame is emitted due to malfunction, it may result in a fire.

• Do not install in any location where the inverter could come into contact with water or other fluids. This can result in electric shock or fire.

• Must be used in the envi ronmental conditions prescribed in the instruction manual. Use under any other conditions may result in malfunction.

• Must be installed in non-inflammables such as metals. The rear panel gets very hot. 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. shut

off input power then engage mechanical brake). 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 accident.

Warning

• 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.

Prohibited

Mandatory

• Do not install in any area where the unit would be subject to large amounts of vibration. That could result in the unit falling, resulting in injury.

• 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.

1.4.4

■ Wiring

• Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3). That will destroy the inverter and may result in fire.

• Do not connect resistors to the DC terminals (across PA-PC or PO-PC). That may cause a fire.

Prohibited

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

• Within ten minutes after turning off input power, do not touch wires of devices (MCCB) connected to the input side of the inverter . That could result in electric shock.

Danger

2.2

E6580757

Mandatory

Be Grounded

Danger

• 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) 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 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.

• Ground must be connected securely. If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or current leak occurs.

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-

Mandatory

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 current do not assume a precise sine wave, they have a distorted wave that is close to sinusoidal waveform. This is why compared to operation with a commercial power there will be a slight increase in motor 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 (

E6580757

)".

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 adjusted 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 lubricating effect. Check with the manufacturer of the reduction gear to find out about operable gearing area.

A-10

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 powe r is cut off install an auxili ary brake. There are different kinds of brake devices, both electrical and mechanical. Select the brake that is best for the system.

E6580757

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.

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 elevators. Please confer with us before designing the system.

1.4.2 Inverters

E6580757

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 operation, 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.

Inverter

Remove the power factor improving capacitor and surge absorber

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 tr ansformer to raise or lower the voltage to the rated voltage.

Breaking of selected inverter

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 cannot 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 input/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 systems. 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.

A-13

E6580757

Power supply

ELCB

Leak current path across gr oun d

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

Inverter

Thermal relay

Power supply

Leak current path across wires

(1) Thermal relays

The high frequency component of current leaking into electrostatic capacity between inverter ou tput 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 thermal 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 current will increase in proportion to the motor rating.

Inverter

A-14

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 superimposed 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 increase in proportion to the motor's rated current.

E6580757

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.

■ How to install

Prohibited

Mandatory

E6580757

Danger

• 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.

• 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 accident.

Warning

• 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 centimeters, 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).

■ 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 gr ound terminals (

A-19

E6580757

• 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.

■ 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.

2.1 Cautions on wiring

• 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.

Prohibited

Mandatory

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.

Danger

B-1

E6580757

Danger

• Ground must be connected securely. If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or current leak occurs.

Be Grounded

Warning

• 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.

Prohibited

■ 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 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.

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

2.2 Standard connections

Danger

• 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.

Prohibited

Always connect

to ground

• 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.

• 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.

3. Operations

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

Prohibited

Mandatory

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 unexpectedly restarts.

• 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.

• 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.

4. Basic VF-S9 operations

The VF-S9 has the following three monitor modes.

E6580757

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 designated 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.

2) Increasing torque manually (V/F constant control) The VF-S9 inverter is set to this control mode by factory default.

This is the setting of constant torque characteristics that are suited for such things as conveyors. It can also be used to manually increase starting torque.

If V/F constant control is programmed after changing

★ 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 hi gh-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 motor constant can be set automatically (auto-tuning). Set the extended parameter ⇒ 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 sensorless 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 ( control unusable.

1) Setting the electronic thermal protection characteristics sel ection and motor electronic thermal protection level 1

The electronic thermal protection characteristics selection i s used to enable or disable the motor overload trip function ( ) and the overload stall function. While the inverter overload trip ( can be selected using the parameter .

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

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 decreases.

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 fo r 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.
