Safety Precautions

This inverter is for driving a 3-phase motor, and must not be used for other applications. [I] Always observe the following items to prevent electrical shock.

1. Do not touch charged parts such as the terminal block while the CHARGE lamp is lit. A charge will still be present in the electrolytic capacitors, and therefore, touching these areas may result in an electrical shock. Always turn the inverter’s input power off before wiring the motor terminals. Walt at least five minutes after the "CHARGE' lamp has gone out, and then confirm that the capacitors have fully discharged by using a tester, etc., that can measure high-voltage DC.

2. Do not touch or insert a rod or any other item into the inverter while power is applied (there are high voltage areas on the PCB), as this may lead to electrical shock or inverter damage. (When operating with the cover removed, charged areas will be exposed, so always install the unit inside a panel so that it cannot be easily touched.) Never attempt to modify the inverter unit.

3. Ground the unit’s G/E terminal and the motor. (Electric

shock may occur due to leakage currents.)

[n] Retry function

1. This inverter has a "retry function" that automatically resets the unit when a fault trip occurs. Observe the

following points when this function is selected. Even if the inverter has fault tripped, take care to not get caught in the motor or equipment. When the "retry function" is selected, the inverter will automatically start after the designated time. (Refer to page

78.)

Take special care when an overload trip occurs, as the "retry function" may activate after a delay of up to 5min.

[m] Observe the following points to prevent fire.

High voltage area

1. Confirm the inverter’s rating nameplate, and connect a 3-phase input power source within the rated range

to the RA.1, S/L2, and TA- 3 power source terminals.

If an Incorrectly-rated power source is connected to the inverter, such as when a 400V power source is

connected to a 200V inverter, the inverter’s internal components may explode.

2. No fuse is contained in the inverter, so instail a suitable non-fuse breaker (MCCB) on the inverter’s input

power source.

(Refer to Table 5-1 on page 14 for Examples of selecting equipment for wiring.)

4. Operation Precautions

Observe the following points when using the VF-A5 inverter

4.1 Cautions Regarding Motor

Comparison with com

mercial power source

operation:

Running at low-speeds:

Adjustment of overload protection level:

Running at speeds exceeding 60Hz:

The VF-A5 inverter uses a sinusoidal-wave PWM method, but the output voltage and output currertt will be distorted waveforms which closely approximate sinusoidal waveforms, instead of complete sinusoidal waveforms. In comparison to operating with the commercial power source, the motor temperature rise, noise and vibration will increase slightly.

When the inverter is used in combination with a general purpose motor and run at low speeds, the motor’s cooling effect will decrease. Therefore, the output load must be reduced to less than the rated load. If the motor is to be run at the rated torque even at low speeds, use a Toshiba 'VF motor* specially designed for use with inverters. When used with a VF motor, the inverter’s overload protection level must be adjusted. (Refer to pages 72, 73 for details.)

When using this inverter with a general purpose motor, the overload protection of the VF-A5 is performed by use of an overioad detection circuit (electronic thermal relay) that meets a general purpose motor’s reduced load characteristics. The reference current value for this electronic thermal relay is set to the inverter’s rated current value; therefore, this may need adjustment depending on the motor.

When operating at a frequency that exceeds 60Hz, motor vibration and noise wiil increase. Furthermore, this type of operation may be limited by the motor’s mechanical strength and bearing construction, so please contact the motor manufacturer for further information.

Load equipment lubrication method:

Ultra-light loads and lowinertia loads:

Measures for instability phenomena:

When driving an oil-lubricated speed reduction gear or geared motor,

the lubrication may deteriorate at low-speeds, so contact the speed

reduction gear manufacturer for information on usable variable-speed

areas.

Instability phenomena, such as abnormal vibration or overcurrent trips, may occur when operating with an ultra-light load at a load ratio of 5% or less, or with a load having an extremely small moment of inertia In these cases, lower the carrier frequency. (Refer to page 66)

Instability phenomena may also occur when using the inverter with the following types of motors or loads, so always confirm applicability before use.

(1) Combination with motor exceeding recommended applicable

motor rating.

(2) Combination with special motors such as explosion-proof motors.

(3) Combination with special loads having severe rotational

fluctuations, such as piston-type movements.

- 5 -

Braking during power off:

The inverter will enter the coast-stop state when the power source is turned off. The motor will therefore not stop immediately. To stop the

motor immediately, install an auxiliary brake unit. Dynamic braking units and mechanical braking units are available, so select one that suits your specific appiication.

Loads that generate a negative torque:

Motors with brakes:

The overvoltage protection or overcurrent protection may function and trip the inverter when used with loads that generate a negative torque,

in this case, a braking resistor that meets the load condition must be instalied.

If a motor with a brake is directly connected to the inverter, the

voltage when the motor is started will be low, which may result in the

brake not being released. In this case, separately wire the brake circuit and motor main circuit. In addition, there is a delay in the time to when the inverter output stops if the inverter’s ST to CC control terminal connection is released, so use of the circuit configuration in Fig. 4-1 is recommended. In Fig. (a), the brake power is turned ON and OFF via MC2 and MC3.

If a circuit configuration as shown in the drawing is not used, a bound current may flow during braking and may cause an overcurrent trip.

The brake power can also be turned ON and OFF using the low-

speed signal LOW as shown in Fig. (b).

(Non-excited brake)

Fig.4.1 Circuit configuration for motor with brake

In some cases, such as in hoist applications, turning the brake ON and

OFF by using low-speed detection (LOW terminal function) may be better, so contact your dealer for further details.

4.2 Cautions Regarding the inverter

Inverter’s overcurrent protection:

Overcurrent protection is used as the VF-A5 inverter’s protection function, and the current setting level is set to match the largest applicable motor. Therefore, when operating a motor that is smaller than the inverter capacity, the overcurrent level and electronic thermal

protection parameters must be readjusted. (Refer to pages 72, 73.)

Running with light loads:

Operating a large capacity motor with a light load using a small capacity (kVA) inverter must be avoided. The output peak current will increase due to the current ripple, and overcurrent trips may frequently occur.

Power-factor improvement

capacitors;

Use with voltage sources other than the rated voltage:

Protection device for lightning surges:

Power-factor improvement capacitors must not be installed on the inverter’s output. When operating a motor with power-factor improvement capacitors installed, remove the capacitors, or the inverter may fault trip or the capacitors may be damaged.

Use with voltage sources other than the rated voltage is not possible. If necessary, use a transformer, etc., to increase or decrease the

source voltage to the rated voltage. A DSA (lightning surge absorber) is used for protection in the unit. If a

surge voltage exceeding 2600 to 3600V peak is applied, the device will light like a glowing electrical discharge. This will cause no

problems if the condition does not continue for an extended period of

time.

(Refer to Fig. 6-2-1 Fig. ® on page 21.)

7 -

Use of multiple inverter units:

Observe the following points when using multiple inverter units on the same power source line.

High-speed

As Shown above, there is no fuse installed in the inverter’s main

circuit, if a short circuit fault occurs in the inverter, not only MCCB2

will trip, but the main breaker MCCB1 may also trip. Select the shut-off characteristics of MCCB1 and MCCB2 so that a selective shutdown can be executed and only MCCB2 trips. If the optimum characteristics cannot be selected, install a high-speed shut off fuse after MCCB2. (Refer to page 14 for MCCB selection.)

4.3 Inverter Disposal Precautions

Observe the following points when disposing of the inverter.

Explosions from incineration:

Gasses from plastics:

Disposal method:

Placing the inverter in an incinerator may be dangerous, as the

electrolytic fluid used in the electrolytic capacitors may expand and

explode. The plastic used for the cover, etc., may generate poisonous gases

when incinerated.

Commission the disposal of the inverter to a specialist.

5. Wiring Precautions

5.1 Connection to Main Circuit (Refer to page 11, Fig. 5.1.)

Observe the following precautions when making connections to the inverter.

Confirmation of power OFF:

Electrical shock preventionconfirmation of charge dissipation:

Confirmation of main circuit connections:

Separation of power source and motor wiring:

Separation of control and main power supplies:

Always turn the primary power distribution panel switch OFF, and confirm with a tester that a voltage is not present before beginning

wiring to the inverter.

Before changing the wiring, wait at least five minutes after the

•CHARGE“ lamp inside the inverter has gone out, and then confirm

that the capacitors have fully discharged by using a tester, etc., that

can measure high-voltage DC. The internal electrolytic capacitors are charged, and there is a danger of electrical shock If the charged areas are touched while the "CHARGE' lamp is on. Do not touch the

terminal block or remove the upper cover while the lamp is lit The inverter will be damaged If the input power source is applied to

the motor terminals (U/T1, V/T2, W/T3). Always confirm the wiring for the power source terminals (R/L1, S/L2, T/L3) and motor terminals

(U/T1, V/T2, W/T3) before turning the power on.

To prevent problems due to radio-frequency noise, etc., do not bundle the wiring to the input power terminals (R/L1, S/L2, T/L3) and the

motor terminals (U/T1, V/T2, VJfTS) together. In order to maintain the control power supply to display faults or to

operate the communication options while the main circuit power is

shut down, remove the two shorting bars (between R/L1-R0, S/L2-S0)

on the control power supply terminal block. Connect the control power to a power source that is separate from the main circuit supply.

5.2 Connection of Control Signals

Observe the following points when making control signal connections.

Rating of relay contacts:

Power wiring for control

circuit: Control wiring wire sizes:

Isolation from main circuit:

Use a relay intended for use with micro-current (min. applicable load rating less than 4mA-24V.), and install a surge killer on the relay’s

exciting coil.

Use shielded wiring or twisted-pair wiring for the control circuit, and

separate the wiring from the main circuit wiring.

The following wiring sizes for the control circuit are recommended.

Frequency setting signal input, frequency meter, ammeter: shielded wire that is 0.3mm® or larger Other signals: Vinyl-insulated wire that is 0.75mm® or larger

All control terminals other than FLA, FLB and FLC are connected to Internal electronic circuits, so input signals must always be electrically isolated from the main circuit.

Ratings of connected meters:

Connect a full-scale 1 mAdc DC ammeter or full-scale 7.5Vdc-1 mA DC voltmeter to the control terminals.

Rating of FL signal contacts:

External use of control power:

Open collector outputs:

Frequency-setting potentiometer:

5.3 Other Precautions

Use of crimp-on terminal lugs:

The contact rating of the protection operation detection relay (FL) is 250Vac (cos0=O.4) 30Vdc-1A.

A max. of 24Vdc-100mA can be used from the P24 control power terminal to drive external relays.

The RCH and LOW control terminals are open-collector outputs, and can output a max. 24Vdc-50mA. Use of a 24Vdc OMRON MY1 relay (RY) is recommended.

Always install a diode (200V-1A class) for surge absorption. Take special note of the diode polarity to avoid incorrect application.

Use a potentiometer rated at 1k to 10kO-1/4W for the frequency setting Input signal.

The clearance between terminals on the inverter main circuit terminal block is small, so use sleeved crimp-on terminal lugs for all main circuit terminals. Take special care during connection so that the terminal lugs do not make contact with neighboring terminal lugs.

P2<

RCH

Grounding terminal:

Built-in braking resistor

Internally-connected (E) terminal:

The main circuit wiring is shown in Fig. 5.1.

(For 3.7kW or less, not showing control power terminals RO, SO)

Always ground the G/E grounding terminal with a wire that is 3.5mm® or larger.

For inverter capacities that are 3.7kW or less, a built-in braking resistor is connected between the main circuit terminals (PA1) and (PB1), providing dynamic braking as a standard feature.

The (E) terminal is for internal connections, so do not remove

connections from it or make any external connections to it.

-10 -

Note) A DC reactor (stand-alone type option) can be installed on 5.5kW and larger units. (Refer to the

function of main circuit terminals PO and PA on page 18.)

Installation of non-fuse breaker (1) Install a non-fuse breaker (MCCB) for wiring protection on the input power source side.

(2) Avoid frequent starting/stopping by turning the non-fuse breaker ON and OFF. (3) Start and stop by turning terminals F to CC (or R to CC) ON and OFF.

Installation of primary magnetic contactor (Refer to page 14; Examples of selecting equipment for wiring.)

(1) When using an external braking resistor, install a magnetic contactor (MC) or non-fuse breaker with

trip coil (MCCB) on the inverter's power supply input side for protection. Make sure that the power circuit can be opened with the built-in fault detection relay (FL).

(2) The VF-A5 has a built-in fault detection relay (FL). Connect the contacts of this relay to the primary side

magnetic contactor (MC) operation terminals, so that the MC can be opened when the inverter’s protection circuit functions.

The fault detection relay (FL) contacts (250VAC-1A cos0=O.4) can be directly connected on 200V

systems. When using a 400V system, a transformer must be used to create 200V or less for the FL sequence. If the MC exciting current exceeds the FL contact rating, install another relay step.

(3) Turn terminal F (or R) to CC ON and OFF to frequently start and stop. Due to repeated inrush currents

when the power is turned on, the life of the inverter will be shortened when the primary magnetic

contactor is used to start and stop, so do not use this method to start and stop frequently.

(4) Install a surge killer on the magnetic contactor (MC) exciting coil.

Fig. 5.2 Wiring example using a magnetic contactor

installation restrictions of secondary-side magnetic contactors (1) As a rule, if a magnetic contactor is installed between the inverter and motor, do not turn it ON/OFF

while running. (If the secondary-side contactor is turned ON and OFF while running, a large current may flow in the inverter, causing inverter damage and failure.)

(2) A magnetic contactor may be installed to change the motor or to change to the commercial power

source when the inverter is stopped. Always use an interlock with the magnetic contactor in this situation so that the commercial power supply is not applied to the inverter’s output terminals.

Installation of overload relay (thermal relay) (Refer to page 14; Examples of selecting equipment for wiring.)

(1) The VF-A5 has a built-in overload protection function that uses an electronic thermal relay. However,

in the following cases, the thermal relay operation level must be adjusted or an overload relay matching

the motor’s characteristics must be installed between the inverter and motor.

0When using a motor having a rated current value different from a Toshiba general-purpose motor.

(Adjust the electronic thermal level)

©When running a single motor with an output less than the specified standard applicable motor, or

when running several motor simultaneously (An overload relay must be installed on each motor.)

Note) If the motor cables for a 400V class inverter are long, the thermal

relay may malfunction. In this case, lower the carrier frequency (refer

to adjustment parameters on page 66), or install a 0.1/r to O.SpF-

1000V film capacitor between the input/output terminals of each phase’s thermal relay.

< Example > When using external thermal relays, the inverter can be externally fault-tripped and

immediately stopped by using the following method (Fig. 5.3).

Note) In this case, ensure that S4 is set to 'Emergency

stop function", by setting | /h H [in

0 r. 5 h to ID.

If the Th-Ry functions, the inverter will display

• E ', and fault trip.

* Other unused terminals can also be used instead of the S4

terminal.

Fig. 5.3 Wiring example using external thermal relays

C r. 51 etc., indicate the LED display on the operation panel. (Refer to Appendix 3, Character

codes, on page 123. The boxed items indicate a parameter or panel operation key.

When using the VF-A5 to drive a Toshiba VF motor*, designed exclusively for constant torque/inverter-

(2)

driven applications, set the electronic thermal protection characteristics for a VF motor.

(Refer to pages 72, 73, Electronic Thermal Protection.)

For protection measures, use of a motor with an imbedded-type thermal relay in the motor coil is

(3)

recommended when running a motor at low speeds.

Restrictions on the installation of power-factor improvement capacitors (both input/output)

Do not install power-factor improvement capacitors on the input or output sides of the inverter. Large currents containing high frequency elements may flow to the capacitors and adversely affect them. Capacitors on the output side may cause the inverter to overcurrent trip. Install an input reactor or De link reactor (optional) for power-factor improvement.

Countermeasures against radio wave interference

The inverter may cause radio wave interference to audio equipment, etc., used near the inverter. In this case, install a radio noise reduction filter (optional) on the inverter’s power source side, or shield the cables to the motor with a conduit to reduce the interference. Contact your dealer for further details.

Cautions concerning ground faults

Verify that there are no incorrect connections between the motor and inverter and that there are no short circuits in the motor before beginning operation. Do not ground the neutral point of a starconnected motor.

Installation of an input reactor

An input reactor can be used to improve the input power-factor, to suppress high harmonic elements, and to miminize the risk of damage to the inverter that may be caused by sudden power fluctuations. Always install an input reactor when connecting the inverter to the following types of systems.

(1) When power source capacity is SOOkVA or more, and when power source capacity is greater than

the inverter capacity by a factor of 10 times or more. When connecting the inverter to the same power system as thyristor-commutated control

(2)

equipment.

When connecting the inverter to the same power system as a distorted-wave generation source,

(3)

such as an arc furnace or thyristor-switched converter unit.

Leakage currents

Leakage currents may increase slightly depending on the connection method. (1) When multiple inverters are connected to one ELCB, increase the ELCB current sensitivity value. (2) Keep the wiring length between the inverter and motor as short as possible. (3) Use an ELCB with high-harmonic suppression.

Initiates running. This key is valid only when “Panel control“ is selected.

Stop/reset key

This key functions as the stop key during “Panel control“. In all other

modes, emergency stop is engaged when this key is pressed twice. During an inverter trip, the tripped state can be reset by pressing this key twice. (Refer to section 7.4.7 Fault reset.)

Program key

Changes between settings monitor mode and frequency

display status.

Enter key

Selects or sets the parameter name, data or frequency, etc.

7.2 Basic Operation

Verify the following items before starting operation.

(1) Check that the wiring is correct.

(Refer to Chapter 6, Standard connections, on page 15.)

(2) Check that the power source is the correctly-rated value.

After confirming that there are no mistakes, perform simple operations with the standard settings. Operate according to the following procedure. When performing trial operations, run the motor at a low frequency (approx. 10Hz).

(1) Starting and stopping via the panel

Step Operation

1) Power ON

Turn ON the power source’s non-fuse breaker (MCCB).

If the LED display is OFF, all preparation conditions are not established, so running will not be possible. Terminals ST-CC must be ‘closed*. Running is possible when the LED display is 0.0 . Remote operation mode from the

control terminal block is automatically entered when power is turned on. Changeover to "Panel control".

The panel control LED will light, and operation from the panel will be

possible.

(If this key is pressed again, the panel control LED will go out, and remote

operation mode from the control terminal block will once again be entered.)

Set the operating frequency. The frequency command value can be incremented/decremented with the

UP key (A) or DOWN key (Sy). When one of these keys is pressed, the

LED display will blink, indicating that the value is being changed. When the

desired frequency is displayed, press the frequency will be alternately displayed on the LED display.

The frequency will increase according to the acceleration time, and the motor will rotate. The panel control LED will blink while running.

The frequency will decrease according to the deceleration time, and the motor will decelerate and stop.

Caution

If the power switch is turned off in the 4) state, the motor will coast-stop. However, this method should only be used in the case of an emergency.

Avoid frequent starting and stopping of the inverter by turning the power switch on and off, as this will

shorten the life of the inverter.

(2) Changing the frequency while running

Step

(3) Function setting and adjustment

Use the following procedure to change the "standard settings". First, refer to the parameter list to find the parameter group where the function to be changed is, and how the symbol name is displayed.

Blind function In the standard setting, only groups u, F and U t can be displayed on the panel. The other

groups are blinded via the blind function in group u t ■ Unblind the desired group if necessary.

(Refer to Cr-.L/fc

r-br.U

ENTER

The frequency can be changed while running by pressing the UP key (A) or

DOWN key (^. Note that the frequency command value will change and

the operating frequency will chanae. The operating frequency can be changed even if the ENTER key is not

pressed, but if the power is turned off at this time, the frequency command

value will return to the frequency set before changing.

b L n d Blind function on page 50.)

Operation

dr. U displays only those parameters for which the setting value has been changed by the user,

and the changed setting value differs from the standard default setting. [Auto edit function] The parameter settings can also be changed in this group. However, if a parameter setting value that is the same as the default setting is once again input, that parameter will no longer be displayed in this group.

C i-.U sequentially compares the settings of all parameters to the standard default setting values,

so this process may take several seconds. The 0 t-.U display will blink and may not appear to immediately react, but the C r.U search can be stopped by pressing a key other thani^,

* If the voltage boost value is set too high, the motor will be overexcited, and an OL or OC trip may occur. In

some cases, this may also shorten the life of the inverter.

* The voltage boost value is automatically initially set for the max. applicable motor according to the inverter

capacity. If a standard motor matching the inverter capacity is used, the value does not necessarily need to be adjusted. Even when readjusting, setting to within ±2% of the initial setting value is recommended.

P E set to 3 Automatic torque boost

The load current is detected, and the inverter’s output voltage (torque) is automatically adjusted.

Pfc I and [ Hfc.P I cannot be changed while running. Even if I Hfc.C I , I Hfc.fc | , I nt.u I, I nt.P

Motor requirements when using vector control

1. Motor capacity should be the same as the inverter, or should be a Toshiba general purpose squirrel-

cage type motor or Toshiba constant torque motor that differs by at most 1 rank.

2. No. of motor poles should be 2 to 16.

3. Only one machine should be operated (one motor per inverter).

* The output frequency and set frequency will not match. * The max. wire length that can be used between the inverter and motor is 30m. If 30m is exceeded, the

torque can be improved during deceleration by using auto-tuning, but the torque will drop slightly near 60Hz.

-----------------------------

The vector control function will operate properly with adequate torque and little speed fluctuation when

used below the maximum voltage frequency setting value. However, in situations where the maximum voltage frequency is exceeded (field-weakening area), the same type of characteristics may not be achieved. The maximum voltage frequency setting range during vector control use should be between 40 to 120Hz.

The motor rated voltage parameter i nt.u I is used only to calculate motor constants. The inverter’s max.

output voltage will always depend on the maximum voltage I uL lj f I during vector control.

Cautions during auto-tuning

(T) The motor must be completely stopped before executing auto-tuning. Due to motor residual voltage,

an error may occur in the tuning if executed immediately after stopping.

0 The motor will rotate only slightly during auto-tuning, but use caution, as the main voltage will be

applied.

0 Auto-tuning will normally finish within 3 sec. If an error occurs, the inverter will trip and the motor

constants will not be set.

0 Auto-tuning of special motors, such as high-speed or high-slip motors, is not possible.

★ The auto-tuming error (refer to page 121) will be displayed when auto-tuning fails. * Change the t nfc. /H I setting value if an overvoltage trip ( 0 P) or overcurrent trip (DC ), etc., occur. Then

retry the auto-tuning operation.

The motor's resonant acoustic noise can be changed by changing the PWM carrier frequency. If resonance

occurs between the motor and the load machine or motor fan cover, change the PWM carrier frequency. The PWM carrier frequency | CF can be set between 3kHz and 17kHz. (18.5kW to 75kW units can be adjusted between 3kHz to 15kHz.)

At low-speed and very high-speed operation, the carrier frequency will be automatically adjusted to meet

motor drive requirements. If the carrier frequency is set higher than the default setting value, the overload trip level will automatically be

reduced, which may result in more frequent overload trips.

15kW and smaller units: if the standard 15kHz setting is changed to 17kHz, the overload trip level will be

reduced 4% for 200V units and 6% for 400V units.
