An accident could occur.

Installation

• Install the inverter on a nonflammable material such as metal.

Otherwise fire could occur.

• Do not place flammable matter nearby.

Doing so could cause fire.

iii

• Do not support the inverter by its terminal block cover during transportation.

Doing so could cause a drop of the inverter and cause injuries.

• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.

Doing so could cause fire or an accident.

• Do not install or operate an inverter that is damaged or lacking parts.

Doing so could cause fire, an accident or injuries.

• Do not stand a shipping box.

• Do not stack shipping boxes higher than the indicated information printed on those boxes.

Doing so could cause injuries.

Wiring

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with the exception of those exclusively designed for protection from ground faults) in the path of power lines. Use the devices within the related current range.

• Use wires in the specified size.

Otherwise, fire could occur.

• Do not use one multicore cable in order to connect several inverters with motors.

• Do not connect a surge killer to the inverter's secondary circuit.

Doing so could cause fire.

GENERAL PRECAUTIONS

Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts. Restore the covers and shields in the original state and observe the description in the manual before starting operation.

Conformity to the Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE or TÜV are considered as compliant with the Low Voltage Directive 73/23/EEC.

1. The ground terminal G should always be connected to the ground. Do not use only a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)* as the sole method of electric shock protection. Be sure to use ground wires whose size is greater than power supply lines.

With the exception of those exclusively designed for protection from ground faults.

2. When used with the inverter, a molded case circuit breaker (MCCB), residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) or magnetic contactor (MC) should conform to the EN or IEC standards.

3. When you use a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) for protection from electric shock in direct or indirect contact power lines or nodes, be sure to use type B of RCD/ELCB at the power supply side of the electric equipment for three-phase 200/400 V power supplies. For single-phase 200 V power supplies, use type A.

When you use no RCD/ELCB, take any other protective measure that isolates the electric

equipment from other equipment on the same power supply line using double or reinforced insulation or that isolates the power supply lines connected to the electric equipment using an isolation transformer.

4. The inverter should be used in an environment that does not exceed Pollution Degree 2 requirements. If the environment conforms to Pollution Degree 3 or 4, install the inverter in an enclosure of IP54 or higher.

5. Install the inverter, AC or DC reactor, input or output filter in an enclosure with minimum degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can be easily accessed), to prevent human body from touching directly to live parts of these equipment.

6. To make an inverter with no integrated EMC filter conform to the EMC directive, it is necessary to connect an external EMC filter to the inverter and install them properly so that the entire equipment including the inverter conforms to the EMC directive.

7. Do not connect any copper wire directly to grounding terminals. Use crimp terminals with tin or equivalent plating to connect them.

8. To connect the three-phase or single-phase 200 V series of inverters to the power supply in Overvoltage Category III or to connect the 3-phase 400 V series of inverters to the power supply in Overvoltage Category II or III, a supplementary insulation is required for the control circuitry.

9. When you use an inverter at an altitude of more than 2000 m, you should apply basic insulation for the control circuits of the inverter. The inverter cannot be used at altitudes of more than 3000 m.

10. The power supply mains neutral has to be earthed for the three-phase 400 V class inverter.

 Precautions for use

Driving a 400V general-purpose motor

When driving a 400V general-purpose motor with an inverter using extremely long wires, damage to the insulation of the motor may occur. Use an output circuit filter (OFL) if necessary after checking with the motor manufacturer.

Torque characteristics and temperature rise

When the inverter is used to run a general-purpose motor, the temperature of the motor becomes higher than when it is operated using a commercial power supply. In the low-speed range, the cooling effect will be weakened, so decrease the output torque of the motor. If constant torque is required in the low-speed range, use an inverter rated motor or a motor equipped with an externally powered ventilating fan.

Vibration

When an inverter-driven motor is mounted to a machine, resonance may be caused by the natural frequencies of the machine system.

Note that operation of a 2-pole motor at 60 Hz or higher may cause abnormal vibration.

* The use of a rubber coupling or vibration dampening rubber

is recommended.

* Use the inverter's jump frequency control feature to skip

the resonance frequency zone(s).

In running generalpurpose motors

Noise

When an inverter is used with a general-purpose motor, the motor noise level is higher than that with a commercial power supply. To reduce noise, raise carrier frequency of the inverter. Operation at 60 Hz or higher can also result in higher noise level.

High-speed motors

If the set frequency is set to 120 Hz or more to drive a high-speed motor, test-run the combination of the inverter and motor beforehand to check for safe operation.

Explosion-proof motors

When driving an explosion-proof motor with an inverter, use a combination of a motor and an inverter that has been approved in advance.

Submersible motors and pumps

These motors have a larger rated current than general-purpose motors. Select an inverter whose rated output current is greater than that of the motor.

These motors differ from general-purpose motors in thermal characteristics. Set a low value in the thermal time constant of the motor when setting the electronic thermal function.

In running special motors

Brake motors

For motors equipped with parallel-connected brakes, their braking power must be supplied from the primary circuit. If the brake power is connected to the inverter's power output circuit by mistake, the brake will not work.

Do not use inverters for driving motors equipped with series-connected brakes.

Geared motors

If the power transmission mechanism uses an oil-lubricated gearbox or speed changer/reducer, then continuous motor operation at low speed may cause poor lubrication. Avoid such operation.

Synchronous motors

It is necessary to take special measures suitable for this motor type. Contact IMO for details.

In running special motors

Single-phase motors

Single-phase motors are not suitable for inverter-driven variable speed operation. Use three-phase motors.

* Even if a single-phase power supply is available, use a

three-phase motor as the inverter provides three-phase output.

Environmental conditions

Installation location

Use the inverter within the ambient temperature range from

-10 to +50qC. The heat sink and braking resistor of the inverter may be-

come hot under certain operating conditions, so install the inverter on nonflammable material such as metal.

Ensure that the installation location meets the environmental conditions specified in Chapter 2, Section 2.1 "Operating Environment."

Installing an MCCB or RCD/ELCB

Install a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with the exception of those exclusively designed for protection from ground faults) in the primary circuit of the inverter to protect the wiring. Ensure that the circuit breaker capacity is equivalent to or lower than the recommended capacity.

Installing an MC in the secondary circuit

If a magnetic contactor (MC) is mounted in the inverter's secondary circuit for switching the motor to commercial power or for any other purpose, ensure that both the inverter and the motor are completely stopped before you turn the MC on or off.

Do not connect a magnet contactor fitted with a surge suppressor to the inverter's secondary circuit.

Installing an MC in the primary circuit

Do not turn the magnetic contactor (MC) in the primary circuit on or off more than once an hour as an inverter fault may result.

If frequent starts or stops are required during motor operation, use FWD/REV signals or the RUN/STOP key.

Combination with peripheral devices

Protecting the motor

The electronic thermal function of the inverter can protect the motor. The operation level and the motor type (general-purpose motor, inverter motor) should be set. For high-speed motors or water-cooled motors, set a small value for the thermal time constant and protect the motor.

If you connect the motor thermal relay to the motor with a long wire, a high-frequency current may flow into the wiring stray capacitance. This may cause the relay to trip at a current lower than the set value for the thermal relay. If this happens, lower the carrier frequency or use the output circuit filter (OFL).

xii

Discontinuance of power-factor correcting capacitor

Do not mount power-factor correcting capacitors in the inverter primary circuit. (Use the DC reactor to improve the inverter power factor.) Do not use power-factor correcting capacitors in the inverter output circuit. An overcurrent trip will occur, disabling motor operation.

Discontinuance of surge killer

Do not connect a surge suppressor to the inverter's secondary circuit.

Reducing noise

Use of a filter and shielded wires is typically recommended to satisfy EMC directives.

Combination with peripheral devices

Measures against surge currents

If an overvoltage trip occurs while the inverter is stopped or operated under a light load, it is assumed that the surge current is generated by open/close of the phase-advancing capacitor in the power system.

* Connect a DC reactor to the inverter.

Megger test

When checking the insulation resistance of the inverter, use a 500 V megger and follow the instructions contained in Chapter 7, Section 7.4 "Insulation Test."

Control circuit wiring length

When using remote control, limit the wiring length between the inverter and operator box to 20 m or less and use twisted shielded wire.

Wiring length between inverter and motor

If long wiring is used between the inverter and the motor, the inverter will overheat or trip as a result of overcurrent (high-frequency current flowing into the stray capacitance) in the wires connected to the phases. Ensure that the wiring is shorter than 50 m. If this length must be exceeded, lower the carrier frequency or mount an output circuit filter (OFL).

Wiring size

Select wires with a sufficient capacity by referring to the current value or recommended wire size.

Wiring

Wiring type

Do not use one multicore cable in order to connect several inverters with motors.

Grounding Securely ground the inverter using the grounding terminal.

Selecting inverter capacity

Driving general-purpose motor

Select an inverter according to the applicable motor ratings listed in the standard specifications table for the inverter.

When high starting torque is required or quick acceleration or deceleration is required, select an inverter with a capacity one size greater than the standard.

Transportation and storage

Driving special motors

Select an inverter that meets the following condition: Inverter rated current > Motor rated current

When transporting or storing inverters, follow the procedures and select locations that meet the environmental conditions listed in Chapter 1, Section 1.3 "Transportation" and Section 1.4 "Storage Environment."

1.4 Storage Environment

1.4.1 Temporary storage

Store the inverter in an environment that satisfies the requirements listed in Table 1.1.

Table 1.1 Environmental Requirements for Storage and Transportation

Item Requirements

Storage temperature *

-25 to +70qC

Relative humidity

5 to 95% *

Locations where the inverter is not subject to abrupt changes in temperature that would result in the formation of condensation or ice.

Atmosphere The inverter must not be exposed to dust, direct sunlight, corrosive or flammable

gases, oil mist, vapor, water drops or vibration. The atmosphere must contain only a low level of salt. (0.01 mg/cm

or less per year)

86 to 106 kPa (in storage) Atmospheric

pressure

70 to 106 kPa (during transportation)

*1Assuming a comparatively short storage period (e.g., during transportation or the like). *

Even if the humidity is within the specified requirements, avoid such places where the inverter will be subjected to sudden changes in temperature that will cause condensation to form.

Precautions for temporary storage

(1) Do not leave the inverter directly on the floor. (2) If the environment does not satisfy the specified requirements, wrap the inverter in an airtight

vinyl sheet or the like for storage.

(3) If the inverter is to be stored in an environment with a high level of humidity, put a drying agent

(such as silica gel) in the airtight package described in item (2).

1.4.2 Long-term storage

The long-term storage methods for the inverter vary largely according to the environment of the storage site. General storage methods are described below.

(1) The storage site must satisfy the requirements specified for temporary storage. However, for storage exceeding three months, the ambient temperature should be within the

range from -10 to +30 °C. This is to prevent the electrolytic capacitors in the inverter from deteriorating.

(2) The inverter must be stored in a package that is airtight to protect it from moisture. Include a

drying agent inside the package to maintain the relative humidity inside the package to within 70%.

(3) If the inverter has been installed in the equipment or control board at a construction site where it

may be subjected to humidity, dust or dirt, then remove the inverter and store it in a suitable environment.

Precautions for storage over 1 year If the inverter will not be powered on for a long time, the property of the electrolytic capacitors may

deteriorate. Power the inverters on once a year and keep them on for 30 to 60 minutes. Do not connect the inverters to motors or run the motor.

2.2 Installing the Inverter

(1) Mounting base

The temperature of the heat sink will rise up to approx. 90°C during operation of the inverter, so the inverter should be mounted on a base made of material that can withstand temperatures of this level.

Install the inverter on a base constructed from metal or other non-flammable material.

A fire may result with other material.

(2) Clearances

Ensure that the minimum clearances indicated in Figure 2.1 are maintained at all times. When installing the inverter in the enclosure of you

system, take extra care with ventilation inside the enclosure as the temperature around the inverte

will tend to increase.

Table 2.2 Output Current Derating Factor in

Relation to Altitude

Altitude

Output current derating factor

1000 m or lower 1.00

1000 to 1500 m 0.97

1500 to 2000 m 0.95

2000 to 2500 m 0.91

2500 to 3000 m 0.88

(Note 1)

When inverters are mounted side-by-side without any gap between them or the NEMA1 kit option is mounted on the inverter, the ambient temperature should be within the range from -10 to +40qC.

(Note 2) Do not install the inverter in an environment where it may be exposed to cotton waste or moist dust or dirt which will clog the heat sink in the inverter. If the inverter is to be used in such an environment, install it in the enclosure of your system o

other dustproof containers.

(Note 3) If you use the inverter in altitude above 1000 m, you should apply an output current derating factor as listed in Table 2.2.

2-2

When mounting two or more inverters Horizontal layout is recommended when two or more inverters are to be installed in the same unit or

enclosure. As long as the ambient temperature is 40°C or lower, inverters may be mounted side-by-side without any gap between them. If it is necessary to mount the inverters vertically, install a partition plate or the like between the inverters so that any heat radiating from an inverter will not affect the one/s above.

(3) Mounting direction

Secure the inverter to the mounting base with four screws or bolts (M4) so that the Jaguar CUB logo faces outwards. Tighten those screws or bolts perpendicular to the mounting base.

Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation efficiency of the inverter and cause the overheat protection function to operate, so the inverter will not run.

Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from accumulating on the heat sink.

This may result in a fire or accident.

2.3 Wiring

Follow the procedure below. (In the following description, the inverter has already been installed.)

2.3.1 Removing the Terminal Block (TB) Covers

(1) Removing the control circuit terminal block (TB) cover

Insert your finger in the cutout (near "PULL") in the bottom of the control circuit TB cover, then pull the cover towards you.

(2) Removing the main circuit terminal block (TB) cover

Hold both sides of the main circuit TB cover between thumb and forefinger and slide it towards you.

2.3.4 Wiring Precautions

Follow the rules below when performing wiring for the inverter.

(1) Make sure that the source voltage is within the rated voltage range specified on the nameplate. (2) Be sure to connect the power wires to the main circuit power input terminals L1/R, L2/S and

L3/T (for three-phase voltage input) or L1/L and L2/N (for single-phase voltage input) of the inverter. If the power wires are connected to other terminals, the inverter will be damaged when the power is turned on.

(3) Always connect the grounding terminal to prevent electric shock, fire or other disasters and to

reduce electric noise.

(4) Use crimp terminals covered with insulated sleeves for the main circuit terminal wiring to ensure

a reliable connection.

(5) Keep the power supply wiring (primary circuit) and motor wiring (secondary circuit) of the main

circuit, and control circuit wiring as far away from each other as possible.

• When wiring the inverter to the power source, insert a recommended moulded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with the exception of those exclusively designed for protection from ground faults) in the path of power lines. Use the devices within the related current range.

• Use wires in the specified size.

Otherwise, fire could occur.

• Do not use one multicore cable in order to connect several inverters with motors.

• Do not connect a surge killer to the inverter's secondary circuit.

Doing so could cause fire.

• Be sure to connect the grounding wires without fail.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

• Be sure to perform wiring after turning the power off.

• Ground the inverter according to the requirements of your national and local safety regulations.

Otherwise, electric shock could occur.

• Be sure to perform wiring after installing the inverter body.

Otherwise, electric shock or injuries could occur.

• Check that the number of input phases and the rated voltage of the product match the number of phases and the voltage of the AC power supply to which the product is to be connected.

Otherwise fire or an accident could occur.

• Do not connect the power source wires to output terminals (U, V, and W).

• Do not connect a braking resistor to between terminals P (+) and N (-), P1 and N (-), P (+) and P1, DB and N (-), or P1 and DB.

Doing so could cause fire or an accident.

(This figure is a virtual representation.)

2-8

The wiring procedure for the CUB5A-1 is given below as an example. For other inverter types, perform wiring in accordance with their individual terminal arrangement. (Refer to page 2-3.)

c Grounding terminals ( G)

Be sure to ground either of the two grounding terminals for safety and noise reduction. All metal frames of electrical equipment must be grounded to avoid electric shock, fire and other disasters.

Figure 2.4 Grounding Terminal

Wiring

Grounding terminals should be grounded as follows:

1) Connect the grounding terminal of the 200 V or 400 V series of inverters to a ground electrode on which class D or C grounding work has been completed, respectively, in compliance with the Electric Facility Technical Standard.

2) Connect a thick grounding wire with a large surface area and which meets the grounding resistance requirements listed in Table 2.7. Keep the wiring length as short as possible.

Above requirements are for Japan. Ground the inverte

according to your national and local safety requirements.

Inverter output terminals, U, V, and W

1) Connect the three wires of the 3-phase motor to terminals U, V, and W.

2) The wiring length between the inverter and motor should not exceed 50 m. If the wiring length exceeds 50 m, it is recommended that an output circuit filter (option) be inserted.

Figure 2.5 Inverter Output Ter-

minal Wirin g

Do not use one multicore cable to connect several inverters with motors.

2-9

No output circuit filter inserted Output circuit filter inserted

• Do not connect a condensive capacitor or surge absorber to the inverter output terminals.

• If the wiring length is long, the stray capacitance between the wires will increase, resulting in an outflow of the leakage current. It will activate the overcurrent protection, increase the leakage current, or will not assure the accuracy of the current display. In the worst case, the inverter could be damaged.

• If more than one motor is to be connected to a single inverter, the wiring length should be the total length of all motor cables.

Driving 400 V series motor

• If a thermal relay is installed in the path between the inverter and the motor to protect the motor from overheating, the thermal relay may malfunction even with a wiring length shorter than 50 m. In this situation, add an output circuit filter (option) or lower the carrier frequency (Function code F26: Motor sound.

• If the motor is driven by a PWM-type inverter, surge voltage that is generated by switching the inverter component may be superimposed on the output voltage and may be applied to the motor terminals. Particularly if the wiring length is l ong, the surge voltage may deteriorate the insulation resistance of the motor. Consider any of the following measures.

- Use a motor with reinforced insulation.

- Connect an output circuit filter (option) to the output terminals of the inverter.

- Minimize the wiring length between the inverter and motor (10 to 20 m or less).

Braking resistor terminals, P(+) and DB

1) Connect terminals P and DB of a braking resistor to terminals P(+) and DB on the main circuit terminal block. (For the braking resistor built-in type, refer to the next page.)

2) When using an external braking resistor, arrange the inverter and braking resistor to keep the wiring length to 5 m or less and twist the two wires or route them together in parallel.

Never insert a braking resistor between terminals P(+) and N(-), P1 and N(-), P(+) and P1, DB and N(-), or P1 and DB.

Doing so could cause fire.

Main circuit power input terminals, L1/R, L2/S, and L3/T (for three-phase voltage input)

or L1/L and L2/N (for single-phase voltage input)

1) For safety, make sure that the molded case circuit breake

(MCCB) or magnetic contactor (MC) is turned off before wiring the main circuit power input terminals.

2) Connect the grounding wire of the main circuit power input terminals (L1/R, L2/S and L3/T or L1/L and L2/N) to the grounding terminal (

G).

3) Connect the main circuit power supply wires (L1/R, L2/S and L3/T or L1/L and L2/N) to the input terminals of the inverter via an MCCB or residual-current-operated protective device (RCD)

/earth leakage circuit breake

(ELCB)*, and MC if necessary.

It is not necessary to align phases of the power suppl

wires and the input terminals of the inverter with each other.

* With the exception of those exclusively designed for protection

from ground faults

Figure 2.10 Main Circuit Power Input

Terminal Connection

It is recommended that a manual on/off magneti

contactor be connected. This is to enable you to disconnect the inverter from the power supply at an emergency (e.g., when the protective function is activated) so as to prevent a failure or accident from causing the secondary problems.

2.3.6 Replacing the Main Circuit Terminal Block (TB) Cover

1) As shown in Figure 2.11, pull out the wires from the main circuit terminals in parallel.

2) Hold both sides of the main circuit TB cover between thumb and forefinger and slide it back into place. Pull the wires out through the grooves of the main circuit TB cover.

Replace the main circuit TB cover, taking care not to apply any stress to the wires. Applying stress to the wires will impose a mechanical force on the screws on the main circuit terminals, which may loosen the screws.

Figure 2.11 Replacing the Main Circuit Terminal Block (TB) Cover

2-13

2.3.7 Wiring for Control Circuit Terminals

Generally, the sheath of control circuit wires is not reinforced by any insulation. If the control circuit wires come into direct contact with the live main circuit terminal, therefore, the sheath may break. Accordingly, there is a possibility that high voltage on the main circuit may be applied to the control circuit wires. It is DANGEROUS. Be sure to keep the control wires away from the live main circuit terminals.

An accident or electric shock could occur.

Noise may be emitted from the inverter, motor and wires. Implement appropriate measure to prevent the nearby sensors and devices from malfunctioning

due to such noise.

An accident could occur.

Figure 2.12 Example of Control

Circuit Wiring

Table 2.8 lists the symbols, names and functions of the control circuit terminals. The wiring to the control circuit terminals differs depending upon the setting up of the inverter using the function codes.

Basically, replace the main circuit TB cover and then connect wires to the control circuit terminals. As shown in Figure 2.12, pull the wires out through the guides on the main circuit TB cover. Route these wires correctly to reduce the influence o

noise, referring to the notes on the following pages.

- Since weak analogue signals are handled, these signals are especially susceptible to the external noise effects. Route the wiring as short as possible (within 20 m) and use shielded wires. In principle, ground the shielding layer of the shielded wires; if effects o

external inductive noises are considerable, connection to terminal [11] may be effective. As shown in Figure 2.13, ground the single end of the shield to enhance the shielding effect.

- Use a twin contact relay for weak signals if the relay is used in the circuit. Do not connect the relay's contact to terminal [11].

- When the inverter is connected to an external device outputting the analog signal, a malfunction may be caused by electric noise generated by the inverter. If this happens, according to the circumstances, connect a ferrite core (a toroidal core or an equivalent) to the device outputting the analog signal and/or connect a capacitor having the good cut-off characteristics for high frequency between control signal wires as shown in Figure 2.14.

- Do not apply 7.5 V or higher to terminal [C1] continuously. Doing so could damage the internal control circuit.

(1) Used to connect the inverter with PC or PLC using RS485 port. (2) Used to connect the inverter with the remote keypad. The inverter

supplies the power to the remote keypad through the extension cable for remote keypad.

This terminal can be used with standard inverters equipped with an RS485 communications card (option).

Route the wiring of the control terminals as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions.

- Fix the control circuit wires inside the inverter to keep them away from the live parts o

the main circuit (such as the terminal block of the main circuit).

2.3.8 Switching of SINK/SOURCE (Jumper Switch)

Before changing the jumper switch, wait for at least five minutes after the power has been turned off, then check that the DC link circuit voltage between main circuit terminals P (+) and N (-) does not exceed the safety voltage (+25 VDC) using a multimeter. An electric shock may result if this warning is not heeded as there may be some residual electric charge in the DC bus capacitor even after the power has been turned off.

Figure 2.17 Switching of SINK/SOURCE (Jumper Switch)

To switch the sink/source of the digital input signal, change the position of the jumper switch using a pair of long-nose pliers, as shown in Figure 2.17.

(Option)

When an optional RS485 communications card is to be used, install it before replacing the main circuit TB cover. Align the card with the latch on the inverter and attach the card to the connector that is located above terminals [30A], [30B] and [30C].

After an RS485 communications card is installed, do not remove the control circuit TB cover when the power is turned on since there is high-voltage electronic devices on the RS485 communications card.

Doing so could cause electric shock.

2.3.10 Replacing the Control Circuit Terminal Block (TB) Cover

Upon completion of the wiring of the control circuits, fit the latches provided on the upper end of the control circuit TB cover into the openings in the front face of the inverter, and then close the TB cover.

NOTE: Take care not to pinch the signal lines between the TB cover and inverter body.

(*When connecting the RS485 communications cable, remove the control circuit TB cover and snip off the barrier of the RS485 communications cable port using nippers.)

2.3.11 Cautions Relating to Harmonic Component, Noise, and Leakage Current

(1) Harmonic component

Input current to an inverter includes a harmonic component, which may affect other loads and condensive capacitors that are connected to the same power source as the inverter. If the harmonic component causes any problems, connect a DC reactor (option) to the inverter. It may also be necessary to connect an AC reactor to the condensive capacitors.

(2) Noise

If noise generated from the inverter affects other devices, or that generated from peripheral equipment causes the inverter to malfunction, follow the basic measures outlined below.

1) If noise generated from the inverter affects the other devices through power wires or grounding wires:

- Isolate the grounded metal frames of the inverter from those of the other devices.

- Connect a filter to the inverter power wires.

- Isolate the power system of the other devices from that of the inverter with an EMC isolating transformer.

2) If induction or radio noise generated from the inverter affects other devices through power wires or grounding wires:

- Isolate the main circuit wires from the control circuit wires and other device wires.

- Put the main circuit wires through a metal conduit and connect the pipe to the ground near the inverter.

- Mount the inverter onto a metal board and connect the whole board to the ground.

- Connect an EMC filter to the inverter power wires.

3) When implementing measures against noise generated from peripheral equipment:

- For the control circuit wires, use twisted or shielded-twisted wires. If using shielded-twisted wires, connect the shield of the shielded wires to the common terminals of the control circuit.

- Connect a surge absorber in parallel with a coil or solenoid of the magnetic contactor.

(3) Leakage current

Harmonic component current generated by transistors (IGBTs) switching on/off in the inverter forces leakage current through stray capacitors of inverter input and output wires or a motor. If any of the problems listed below occur, take appropriate measures against them.

Table 2.9 Leakage Current Countermeasures

Problem Measures

An earth leakage circuit breaker* that is connected to the power supply has isolated the inverter from the power supply.

* With the exception of those exclusively designed for protection from ground faults

1) Decrease the carrier frequency.

2) Make the wires between the inverter and motor shorter.

3) Use an earth leakage circuit breaker that has a larger current sensitivity than one currently being used.

4) Use an earth leakage circuit breaker that features measures against harmonic component.

An external thermal relay was activated.

1) Decrease the carrier frequency.

2) Increase thermal time constant.

3) Use the thermal relay built in the inverter.

* Menu #7 appears only when the remote keypad (option) is set up for use.

If the full-menu mode is selected, pressing the or key will cycle through menus. With the key, you may select the desired menu. Once all of the menus have been cycled through, the display will return to the first menu.

3.2.3 Alarm Mode

When the protective function is activated to issue an alarm, the inverter automatically transfers to Alarm mode and the alarm code will appear in the LED monitor. Figure 3.2 shows the status transition of Alarm mode.

Releasing the Alarm and Transferring the Inverter to Running Mode

Remove the cause of the alarm and press the key to release the alarm and return to Running mode. The alarm can only be removed using the

key when the alarm code is displayed.

Displaying the Alarm History

It is possible to display the most recent 3 alarm codes in addition to the one currently displayed. Previous alarm codes can be displayed by pressing the

or key while the current alarm code is

displayed.

Displaying the Running Information when an Alarm Occurs

If an alarm occurs, you may check various running status information (output frequency and output current, etc.) by pressing the

key when the alarm code is displayed. The item number and data

for each running information is displayed in alternation. Further, you can switch between the various running information using the

or key. Detailed running information is the same as for Menu #6 "Alarm information" in Programming mode. Refer to Table 3.14 in Section 3.9 "Reading Alarm Information."

Pressing the

key while the running information is displayed returns the display to the alarm

codes.

When the running information is displayed after removal of the alarm cause, pressing the

key twice in succession will cause the inverter to transmit to the alarm code display and then release the alarm status. Be careful with a run command. If a run command has been entered at this stage, the motor will start running.

Transit to Programming Mode

Further, it is also possible to switch the inverter to Programming mode by pressing the + keys simultaneously while the alarm is displayed and to then check and adjust the function code data.

3.3 Operation in Running Mode

If the inverter is turned on, it automatically enters Running mode in which you may operate the following:

(1) Run/Stop the Motor

By factory default, pressing the

key starts running the motor in the forward direction and pressing the

key decelerates the motor to

stop. The

key is enabled only in Running

mode. Changing function code F02 data makes it

possible to run the motor in the reverse direction by pressing the

key, determine the motor rotation direction by entering input signals to the terminals, and control the motor by pressing the

/ keys.

■

Direction) and

key

If Function code F02 is set to:

Pressing the

key ro-

tates the motor:

2 in the forward direction

3 in the reverse direction

For setting "0" or "1" to F02, refer to Chapter 5 for details.

(2) Set up the Set Frequency and Others

By using the potentiometer and

/ keys on the keypad, you may set up the desired set frequency and PID process commands. It is also possible to set up the set frequency as frequency, load shaft speed, line speed, and constant rate of feeding time by setting function code E48.

Setting up the set frequency with the built-in potentiometer (factory default)

If you set function code F01 to "4: Enable the built-in potentiometer" (factory default) and select frequency command 1 with function codes E01 through E03 (Hz2/Hz1 = OFF), then the potentiometer becomes enabled to set up the set frequency.

3-7

Setting the set frequency with the and keys

If you set function code F01 to "0: Keypad operation" and select frequency command 1, then the and keys become enabled to set the set frequency in Running mode. In any other operation modes, those keys remain disabled.

Pressing the

or key calls up the set frequency with the lowest digit blinking. Pressing the or

key again makes it possible to change the set frequency. The new setting will be saved internally. Even if the inverter is switched to any other frequency entry and then returned to keypad entry, the setting will be retained.

Further, even turning off the inverter will automatically save the setting into the non-volatile memory. The next time the inverter is turned on, the setting will become the default frequency.

If you set function code F01 to "0: Keypad operation" but do not select frequency command 1 (e.g., you select frequency command 2, communication control, or multistep frequency), then the

and

keys cannot be used for setting the set frequency. Pressing those keys will just display the currently selected set frequency.

• When setting the frequency and others with the and keys, the lowest digit on the display will blink. Change the setting, starting with the lowest digit and the blinking digit (cursor) will move to the next upper digit.

• If you press the

or key once for changing the set frequency or other data and then

hold down the

key for 1 second or longer after the lowest digit starts blinking, the blinking digit will move to the next upper digit so that you may easily access and change higher data values. (Cursor movement)

To set up the set frequency from any other displayed items, it is dependent on function code E48 data (= 4, 5, or 6) "LED monitor details (Select speed monitor)" as listed in the following table.

■

Make setting under PID control

To enable PID control, you need to set function code J01 to 1 or 2. Under the PID control, the items that can be set or checked with the

and keys are different from those under regular frequency control, depending upon the current LED monitor setting. If the LED monitor is set to the speed monitor (E43 = 0), you may access manual feed commands (Set frequency) with the

and keys; if it is set to any other, you may access PID process commands

with those keys.

Setting the PID process command with the built-in potentiomete r

(1) Set function code E60 to "3: PID process command 1." (2) Set function code J02 to "1: PID process command 1. "

Setting the PID process command with the

and keys

(1) Set function code J02 to "0: Keypad operation." (2) Set the LED monitor to the setting other than the speed monitor (E43 = 0) in Running mode.

This setting is possible only in Running mode.

Pressing the

or key displays the PID process command with the lowest digit blinking on the

LED monitor. Pressing the

or key again makes it possible to change the PID process command. Once the PID process command is modified, it will be saved internally. Even if the inverter is switched to any other PID process command entry and then returned to the keypad entry, the setting will be retained.

Further, even turning off the inverter will automatically save the setting into the non-volatile memory. At the next time when the inverter is turned on, the setting will become the default PID process command.

Even if the PID process command is selected ((SS4) = ON) in the multistep frequency, it is still possible to set the process command using the keypad.

When function code J02 data has been set to any value except 0, pressing the

or key dis-

plays the PID process command currently selected (setting is not possible). When the PID process command is displayed, the decimal point next to the lowest digit on the LED

display blinks to discriminate it from the regular frequency setting.

Setting up the set frequency with the and keys under the PID control

To set the set frequency with the and keys under the PID control, you need to specify the following conditions:

- Set function code F01 to "0: Keypad operation."

- Select frequency command 1 (Frequency settings from communications link: Disabled, and Multistep frequency settings: Disabled) as manual speed command.

- Set the LED monitor to the speed monitor in Running mode.

The above setting is impossible in any operation mode except Running mode. The setting procedure is the same as that for usual frequency setting.

■ Displaying I/O signal status in hexadecimal format

Each I/O terminal is assigned to bit 15 through bit 0 as listed in Table 3.12. An unassigned bit is interpreted as "0." Allocated bit data is displayed on the LED monitor in 4-digit hexadecimals ("0" to "F" each).

With the Jaguar CUB, digital input terminals [FWD] and [REV] are assigned to bit 0 and bit 1, respectively. Terminals [X1] through [X3] are assigned to bits 2 through 4. The value "1" is set for each bit when the assigned input terminal is short-circuited with terminal [CM]. The value "0" when it opens. For example, when [FWD] and [X1] are on and all others are off, the display on LED4 to LED1 would be 0005.

The value "1" is set when bit 0 is assigned to digital output terminal [Y1] and the terminal is short-circuited with [Y1E], and the value "0" is set when it opens. The status of the mechanical relay contact output terminal [30A], [30B] and [30C] are assigned to bit 8. The value "1" is set when the circuit between output terminals [30A] and [30C] is closed and the value "0" when the circuit between [30B] and [30C] is closed. For example, if [Y1] is on and the circuit between [30A] and [30C] are short-circuited with each other, then the display for LED4 to LED1 would be 0101.

How the hexadecimal display is configured for the terminals to which bits 15 to 0 are assigned and the 7-segment LED is shown below.

Displaying control I/O signal terminals under communication control

There are two control circuit input displays under communications link control – "display with ON/OFF of the LED segment" and "in hexadecimal format" for input commanded from RS485 communications link. The content is similar to that of the control I/O signal terminal status display; however, (XF), (XR), and (RST) are added as inputs. Under communications control, however, displaying I/O signal status supports only the normal logic system (that is ON-active).

Chapter 4 RUNNING THE MOTOR

4.1 Running the motor for a test

4.1.1 Inspection and Preparation prior to the Operation

Check the following prior to starting the operation. (1) Check if connection is correct. Especially check if the power wires are connected to inverter output terminals U, V and W and

that the grounding wire is connected to the ground electrode correctly.

• Do not connect power supply wires to the inverter output terminals U, V, and W. Otherwise, the inverter may be broken if you turn the power on.

• Be sure to connect the grounding wires of the inverter and the motor to the ground electrodes.

Otherwise, electric shock may occur.

(2) Check for short circuits between terminals

and exposed live parts and ground faults.

(3) Check for loose terminals, connectors and

screws.

(4) Check if the motor is separated from

mechanical equipment.

(5) Turn the switches off so that the inverte

does not start or operate erroneously at power-on.

(6) Check if safety measures are taken against

runaway of the system, e.g., a defense to protect people from unexpectedl

approaching your power system.

Figure 4.1 Connection of Main Circuit Terminals

(Three-phase power supply)

4.1.2 Turning on Pow er and Checking

• Be sure to install the terminal cover before turning the power on.

Do not remove the cover during power application.

• Do not operate switches with wet hands.

Otherwise electric shock could occur.

Turn the power on and check the following points. This is a case when no function code data is changed from the factory setting.

(1) Check if the LED monitor displays "0.00" (means

that the set frequency is 0 Hz) that is blinking. (See Figure 4.2)

If the LED monitor displays numbers except

"0.00," then rotate the potentiometer to set "0.00" as the set frequency.

(2) Check if a built-in cooling fan rotates (for models

with 1.5 kW or more).

Before starting running the motor, set function code data specified in Table 4.1 to the motor ratings and your system design values. For the motor, check the rated values printed on the nameplate of the motor. For your system design values, ask system designers about them.



For details about how to change function code data, refer to Chapter 3, Section 3.4 "Setting the Function Codes." If the motor capacity is different from the inverter capacity, refer to Chapter 5, function code H03.

4.1.4 Test run

If the user sets the function codes wrongly or without completely understanding this Instruction Manual, the motor may rotate with a torque or at a speed not permitted for the machine.

Accident or injury may result.

Follow the descriptions of the previous Section 4.1.1, "Inspection and Preparation prior to the Operation" to Section 4.1.3, "Preparation before running the motor for a test," and begin testdriving of the motor.

If any abnormality is found to the inverter or motor, immediately stop operation and determine the cause referring to Chapter 6, "TROUBLESHOOTING."

------------------------------------------------ Procedure for Test Run -----------------------------------------------(1) Turn the power on and check that the LED monitor blinks while indicating the 0.00 Hz

frequency.

(2) Rotate the built-in potentiometer clockwise, set the frequency to a low frequency such as 5

Hz. (Check that set frequency blinks on the LED monitor.)

(3) Press the

key to start running the motor in the forward direction. (Check that the set

frequency is displayed on the LED monitor correctly.)

(4) To stop the motor, press the

key.

• Check if the direction of rotation is correct.

• Check for smooth rotation without motor humming or excessive vibration.

• Check for smooth acceleration and deceleration. When no abnormality is found, rotate the potentiometer clockwise to raise the set frequency.

Check the above points for the test-driving of the motor.

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

4.2 Operation

After checking that the operations finished correctly through the above test-driving, start normal operation.

Chapter 5 FUNCTION CODES

5.1 Function Code Tables

Function codes enable the Jaguar CUB series of inverters to be set up to match your system requirements.

Each function code consists of a 3-letter string. The first letter is an alphabet that identifies its group and the following two letters are numerals that identify each individual code in the group. The function codes are classified into seven groups: Fundamental Functions (F codes)

, Extension Terminal Functions (E codes), Control Functions of Frequency (C codes), Motor Parameters (P codes), High Performance Functions (H codes), Application Functions (J codes), and Link Function (y codes). To determine the property of each function code, set data to the function code.

The following descriptions supplement those given in the function code tables on page 5-3 and subsequent pages.

 Changing, validating, and saving function code data when the motor is running

Function codes are indicated by the following based on whether they can be changed or not when the inverter is running:

Notation Change when running Validating and saving function code data

Y* Possible

If the data of the codes marked with Y* is changed, the change will immediately take effect; however, the change is not saved into the inverter's memory. To save the change, press the key. If you press the key without pressing the key to exit the current state, then the changed data will be discarded and the previous data will take effect for the inverter operation.

Y Possible

The data of the codes marked with Y can be changed with the

and keys regardless of whether the motor is running or

not. Pressing the

key will make the change effective and

save it into the inverter's memory.

N Impossible —



Copying data

Connecting a remote keypad (option) to an inverter via the RS485 communications card (CUBRS485) allows copying the data stored in the inverter's memory into the keypad's memory (refer to Menu #7 "Data copying” in Programming mode). With this feature, you can easily transfer the data saved in a source inverter to other destination inverters.

If the specifications of the source and destination inverters differ, some code data may not be copied to ensure safe operation of your power system. Therefore, you need to set up the uncopied code data individually as necessary. Whether data will be copied or not is detailed with the following symbols in the "Data copy" column of the function code tables given below.

Y: Will be copied unconditionally. Y1: Will not be copied if the rated capacity differs from the source inverter. Y2: Will not be copied if the rated input voltage differs from the source inverter. N: Will not be copied. If necessary, manually set the function code data that cannot be copied.

5-19

F10 to F12

Electronic Thermal Overload (Motor property selection, Overload detection level, and Thermal time constant)

F10 through F12 set the thermal characteristics of the motor including the thermal time constant to simulate an overload status of the motor using the built-in electronic thermal processing function of the inverter. This function simulates the motor temperature based on the inverter's internally measured output current. F11 is used to determine the overload detection level.

Thermal characteristics of the motor specified by these function codes are also used for the overload early warning. Therefore, even if you need onl

the overload early warning, set these characteristics data to function codes F10 and F12.

F10 selects the cooling characteristics of the motor--built-in cooling fan or externally powered forced-ventilation fan.

Set F10 to: If the motor is cooled by:

1 Built-in cooling fan for standard purpose motors (self-cooled)

(The cooling performance will decrease with low frequency operations.)

2 Forced-ventilation fan powered by an inverter duty rated motor.

(The cooling performance will be kept constant regardless of the output frequency.)

F11 sets the operation level of the electronic thermal function to the current value. Set approximately 1.0 to 1.1 multiples of the allowable continuous current (rated current of the motor) at the rated drive frequency (base frequency) of the motor under normal running conditions. To disable the electronic thermal function, set 0.00 to F11.

F12 sets the thermal time constant of the motor. The inverter interprets the time constant as an operation period of the electronic thermal function. During the specified operation period, the inverter will activate the electronic thermal function if 150% current of the operation level specified by F11 flows continuously. The time constant of general-purpose motors and other induction motors is set to 5 minutes by factory default.

Data entry range: 0.5 to 75.0 (minutes, in 0.1-minute increment)

F14 Restart Mode after Instantaneous Power Failure

Selects the action of the inverter to be followed when an instantaneous power failure occurs.

If the inverter detects that the DC link circuit voltage has dropped to less than the specified undervoltage limit during operation, it interprets the state as an occurrence of an instantaneous power failure. However, if the inverter runs with a light load and the period of the power failure is too short, then it may not detect the power failure and continue to run.

5-2



Using negative logic for programmable I/O terminals

The negative logic signaling system can be used for the digital input and output terminals by setting the function codes specifying the properties for those terminals. Negative logic refers to inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An ON-active signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to OFF-active signal (the function takes effect if the terminal is opened.) in the negative logic system.

To set the negative logic system for an I/O signal terminal, display data of 1000s (by adding 1000 to the data for the normal logic) in the corresponding function code and then press the

key.

For example, if a coast-to-stop command (BX: data = 7) is assigned to any one of digital input terminals [X1] to [X3] by setting any of function codes E01 through E03, then turning (BX) on will make the motor coast to a stop. Similarly, if the coast-to-stop command (BX: data = 1007) is assigned, turning (BX) off will make the motor coast to a stop.

 Restriction on data displayed on the LED monitor

Only four digits can be displayed on the 4-digit LED monitor. If you enter more than 4 digits of data valid for a function code, any digits after the 4th digit of the set data will not be displayed, however they will be processed correctly.

5.2 Overview of Function Codes

This section provides an overview of the function codes frequently used for the Jaguar CUB series of inverter.

F00 Data Protection

Specifies whether function code data is to be protected from being accidentally changed by keypad operation. If data protection is enabled (F00 = 1),

or key operation to change data is disabled so that no function code data, except F00 data, can be changed from the keypad. To change F00 data, simulta neous keying of +

keys is required.

F01, C30

Frequency Command 1 and 2

Selects the devices to set the set frequency 1 for driving the motor.

Set F01 to: To do this

0 Enable the and keys on the built-in keypad. (Refer to

Chapter 3 "OPERATION USING THE KEYPAD.")

1 Enable the voltage input to terminal [12] (0 to +10 VDC, maximum

frequency obtained at +10 VDC).

Enable the current input to terminal [C1] (+4 to +20 mA DC, maximum frequency obtained at +20 mA DC).

3 Enable the sum of voltage and current inputs to terminals [12] and

[C1]. See the two items listed above for the setting range and maximum frequencies.

Note: If the sum exceeds the maximum frequency, the maximum frequency will apply.

Enable the built-in potentiometer (POT). (Maximum frequency obtained at full scale of the POT)

• There are other frequency command means (such as the communications facility, multistep frequency, etc.) with higher priority than that of F01.

• For frequency commands by terminals [12] (voltage) and [C1] (current) and by the built-in potentiometer, setting the gain and bias changes the relationship between those frequency commands and the drive frequency to enable matching your system requirements. Refe

to function code F18 for details.

• For the inputs to terminals [12] (voltage) and [C1] (current), low-pass filters can be enabled. Refer to function codes C33 and C38 for details.

In addition to "F01 Frequency command 1," "C30: Frequency command 2" is also available. To switch them, use the terminal command (Hz2/Hz1). For details of the (Hz2/Hz1), refer to "E01 to E03: Command Assignment to Terminals [X1] to [X3]."

5-14

F02

Running/Stopping and Rotational Direction

Selects a source issuing a run command--keypad or external control signal input.

- If F02 = 0, 2, or 3, the inverter can run the motor by the

and keys on the built-in keypad. The motor rotational direction can be specified in two ways, either by control signal input (F02 = 0) or by use of prefixed forward or reverse rotation (F02 = 2 or 3).

When F02 = 0, to specify the motor rotational direction by control signal input,

assign the commands (FWD) and (REV) to terminals [FWD] and [REV], respectively. Turn on the (FWD) or (REV) for the forward or reverse direction, respectively, and then press the

key to run the motor.

- If F02 = 1, the inverter can run the motor by control terminal inputs. To specify the motor rotational direction, assign the commands (FWD) and (REV) to terminals [FWD] and [REV], respectively. Turn on the (FWD) or (REV) for the forward or reverse direction, respectively. If both of (FWD) and (REV) are turned on simultaneously, the inverter immediately decelerates to stop the motor.

The table below lists the operational relationship between function code F02 (Running/Stopping and Rotational Direction), the

key operation, and control signal inputs to terminals [FWD] and [REV], which determines the rotational direction.

F03

Maximum Frequency

Sets the maximum frequency to drive the motor. Setting the frequency out of the range rated for the equipment driven by the inverter may cause damage or a dangerous situation. Set a maximum frequency appropriate for the equipment. For high-speed motors, it is recommended that the carrier frequency be set to 15 kHz.

The inverter can easily set high-speed operation. When changing the speed setting, carefully check the specifications of motors or equipment beforehand.

Otherwise injuries could occur.

F04 F05 H50 H51

Base Frequency Rated Voltage (at Base Frequency) Non-linear V/f Pattern (Frequency) Non-linear V/f Pattern (Voltage)

These function codes set the base frequency and the voltage at the base frequency essentially required for running the motor properly. If combined with the related function codes H50 and H51, these function codes may set data needed to drive the motor along the non-linear V/f pattern.

The following description includes setting-up required for the non-linear V/f pattern.



Base frequency (F04)

㩷

Set the rated frequency printed on the nameplate located on the motor.



Rated voltage (at base frequency) (F05)

㩷

Set 0 or the rated voltage printed on the nameplate labeled on the motor.

- If 0 is set, the inverter supplies voltage equivalent to that of the power source of the inverter at the base frequency. In this case, the output voltage will vary in line with any variance in input voltage.

- If the data is set to anything other than 0, the inverter automatically keeps the output voltage constant in line with the setting. When any of the automatic torque boost settings, automatic energy saving or slip compensation is active, the voltage settings should be equal to the rating of the motor.

If F05 is set to match the rated voltage of the motor, motor efficiency will be better than that it is set to 0. Therefore, when brakes are applied to the motor, energy loss decreases and the motor regenerates larger braking energy, which can easily cause the overvoltage protection function (

where n=1 to 3) to be activated. Note that the allowable power consumption capacity of the inverter for braking energy is limited by the specifications. If the overvoltage protection function is activated, it may be necessary to increase deceleration time or use an external braking resistor.



Non-linear V/f pattern for frequency (H50) Sets the non-linear V/f pattern for frequency component. (Setting 0.0 to H50 disables the non-linear V/f pattern operation.)

5-16

 Non-linear V/f pattern for voltage (H51)

Sets the non-linear V/f pattern for voltage component. If the rated voltage at base frequency (F05) is set to 0, the data settings of function

codes H50 and H51 will be ignored.

If you set the data of H50 to 25 Hz or lower (Operation under low base frequency), the inverter output voltage may be limited.

Defining non-linear V/f patterns (F04, F05, H50 and H51)

Function codes F04 and F05 define a non-linear V/f pattern that forms the relationship between the inverter's output frequency and voltage.

Furthermore, setting the non-linear V/f pattern using function codes H50 and H51 allows patterns with higher or lower voltage than that of the normal pattern to be defined at an arbitrary point inside or outside the base frequency. Generally, when a motor is driven at a high speed, its internal impedance may increase and output torque may decrease due to the decreased drive voltage. This feature helps you solve that problem. Note that setting the voltage in excess of the inverter’s input source voltage is not allowed.

 Normal (linear) V/f pattern

 V/f pattern with single non-linear point inside the base frequency

You can also set the optional non-linear V/f range (H50: Frequency) fo

frequencies exceeding the base frequency (F40).

5-17

F09 F37

Torque Boost Load Selection/Auto Torque Boost/Auto Energy Saving Operation

In general, there are two different properties of loads--the torque load which is inversely proportional to the square of speed (fans and pumps) and the constant torque load (industrial machinery). You can select a V/f pattern optimized to the load property.

Manual torque boost In manual torque boost mode, the inverter maintains the output at a constant level

regardless of the load. When you use this mode, select the appropriate V/f pattern (square reduction torque or constant torque characteristics) with Select Load (F37). To keep the motor starting torque, manually select optimal inverter output voltage for the motor and load by setting an optimal torque boost rate to F09 in accordance with the motor and its load.

Setting an excessive torque boost rate may result in over-excitation and overheat of the motor during light or no load operation.

Manual torque boost keeps the output voltage constant even if the load varies, assuring stable motor operation.

Variable torque characteristics (F37 = 0) Constant torque characteristics (F37 = 1)

• Set an appropriate torque boost rate that will keep the starting torque of the motor within the voltage level in the low frequency zone. Setting an excessive torque boost rate may result in over-excitation or overheat of the motor during no load operation.

• The F09 data setting is effective when F37 (Load Selection/Auto Torque Boost/Auto Energy Saving Operation) is set to 0, 1, 3, or 4.

Automatic torque boost This feature automatically optimizes the output voltage to fit the motor and its load.

Under a light load, it decreases the output voltage to prevent the motor from over-excitation; under a heavy load, it increases the output voltage to increase torque.

Since this feature is related to the motor properties, it is necessary to set the rated voltage at base frequency (F05) and motor parameters (P codes) properly.

For the automatic torque boost feature, which is related to the moto

characteristics, you need to consistently set the voltage at the base frequency (F05) and motor parameters P02, P03 and P99 appropriatel

for the motor rating and characteristics.

5-18

Auto energy saving operation This feature controls the terminal voltage of the motor automatically to minimize the

motor power loss. (Note that this feature may not be effective depending upon the motor characteristics. Check the characteristics before using this feature.)

The inverter enables this feature for constant speed operation only. During acceleration and deceleration, the inverter will run with manual or automatic torque boost, depending on function code F37. If auto energy saving operation is enabled, the response to a change in motor speed may be slow. Do not use this feature for a system that requires quick acceleration and deceleration.

When the base frequency is 60 Hz or lower, use the auto energy saving operation. If it is higher than 60 Hz, the decreased or no effect of the auto energy saving operation may be brought about.

The auto energy saving operation is designed for use with the frequenc

lower than the base frequency. If the frequency becomes higher than the base frequency, the auto energy saving operation will be invalid.

For the auto energy saving function, which is related to the motor characteristics, you need to consistently set the voltage at the base frequenc

(F05) and motor parameters P02, P03 and P99 appropriately for the moto

rating and characteristics.

Given below are proper setting examples with the combination of F09 and F37.

5-20

- Trip immediately (F14 = 0) If an instantaneous power failure occurs when the inverter is in Running mode so

that the inverter detects undervoltage of the DC link circuit, then the inverter immediately stops its output and displays the undervoltage alarm "

" on the LED

monitor. The motor will coast to a stop and the inverter will not restart automatically.

- Trip after recovery of power (F14 = 1) If an instantaneous power failure occurs when the inverter is in Running mode,

causing the inverter to detect undervoltage of the DC link circuit, the inverter immediately stops its output without transferring to Alarm mode or displaying the undervoltage alarm "

". The motor will coast to a stop. When the power is

recovered, the inverter will enter Alarm mode for undervoltage.

- Restart at the frequency at which the power failure occurred (F14 = 4) If an instantaneous power failure occurs when the inverter is in Running mode so

that the inverter detects undervoltage of the DC link circuit, then the inverter saves the current output frequency and stops its output to make the motor to coast to a stop. When the power is recovered with any run command being on, the inverter will restart at the saved frequency.

During the instantaneous power failure, if the motor speed slows down, the current limiter function of the inverter will be activated and automatically lower the output frequency. Upon synchronization of the output frequency and motor speed, the inverter accelerates up to the previous output frequency. Refer to the figure (F14 =

4) given below for details. To synchronize the output frequency and motor speed, however, the momentary

overcurrent limiter (H12 = 1) should be enabled. This setting is optimal for operations in which the motor speed rarely slows down

due to the heavy moment of inertia of its load even if the motor coasts to a stop because of the instantaneous power failure.

- Restart at the starting frequency (F14 = 5) If an instantaneous power failure occurs when the inverter is in Running mode so

that the inverter detects undervoltage of the DC link circuit, then the inverter immediately stops its output. After the power is recovered, entry of any run command will restart the inverter at the frequency specified by function code F23.

5-21

This setting is optimal for operations in which the motor speed quickly slows down to 0 rpm due to the heavy load with a very small moment of inertia if the motor coasts to a stop because of the instantaneous power failure.

• There is a 0.5-second delay from detection of the undervoltage until the motor is restarted This delay is due to the time required for the residual electricity (magnetic flux) in the motor to drop sufficiently. Therefore, even if the instantaneous power failure period is shorter than 0.5 second, a delay of at least 0.5 second is required for the motor to restart.

• When an instantaneous power failure occurs, the power supply voltage for external circuitry (such as relay circuits) that controls the inverter may also drop to the extent that run commands are disabled.

Therefore, have the system wait 2 seconds before the issue of run

commands. If any run command is issued within 2 seconds, however, the inverter will restart. If it is after 2 seconds, the inverter will start at the starting frequency preset by the related function codes. The external circuitry should be configured so that it is able to issue any run command within 2 seconds, or so that it features a mechanical latch relay mechanism that ensures the safety of the system in the event o

an instantaneous power failure.

• If a coast-to-stop command (BX) is issued during the time from the detection of an instantaneous power failure to repowering, the inverte

exits from the state of waiting for restarting, and enters Running mode. If any run command is issued, the inverter will start at the starting frequency preset.

If you select restart after instantaneous power failure (F14 = 4 or 5), the inverter will automatically restart running the motor when the power is recovered. The machine should be so designed that human body and peripheral equipment safety is ensured even after automatic restarting.

Otherwise an accident could oc cur.

F15, F16 Frequency Limiter (Upper and Lower)

Frequency limiter F15 limits the upper limiter of output frequency. Frequency limiter F16 maintains the output frequency at the lower limiter even if the set frequency is lower than the lower limiter. Refer to the figure below.

5-22

Set the upper and lower frequencies correctly; otherwise, the inverter ma

not operate. Maintain the following relationship:

(Upper frequency) > (Lower frequency), (Starting frequency), (Stop frequency) (Lower frequency) < (Maximum frequency)

F18 C50 C32, C34 C37, C39

Bias (for Frequency Command 1) Bias (Bias reference point for frequency command 1) Analogue Input Adjustment (Gain and gain reference point for terminal input [12]) Analogue Input Adjustment (Gain and gain reference point for terminal input [C1])

If you select any analogue input for frequency command 1 (set by F01), you can define the relationship between the analogue input and the set frequency arbitrarily by combining the settings for bias (F18), bias reference point (C50), gains (C32 and C37), and gain reference points (C34 and C39).

As illustrated in the graph below, the relationship between the set frequency and analogue input level for frequency command 1 is shown by a straight line passing through points "A" and "B." The point "A" is determined by the bias command (F18) and its reference point (C50). The "B" is determined by the gain commands (C32 or C37) and its reference point (C34 or C39). The combination of C32 and C34 will apply for terminal [12] and that of C37 and C39 for terminal [C1].

The bias (F18) and gain (C32 or C37) should be set, assuming the maximum frequency as 100%. The bias reference point (C50) and gain frequency point (C34 or C39) should be set, assuming the full scale (+10 VDC or +20 mA) as 100%.

Analogue input under the bias reference point is limited by the bias data.

In the above expressions, each function code expresses its data.

Example:

Setting the bias, gain and its reference point when analogue input range

from +1 to +5 VDC is selected for frequency command 1

(Point A) If the analogue input is at 1 V, the set frequency is 0 Hz. Therefore, the bias is 0%

(F18 = 0). Since 1 V is the bias reference point and it is equal to 10% of 10 V, then the bias reference point should be 10% (C50 = 10).

(Point B) If the analogue input is at 5 V, the set frequency comes to be the maximum value.

Therefore, the gain is 100% (C32 = 100). Since 5 V is the gain reference point and it is equal to 50% of 10 V, then the gain reference point should be 50% (C34 = 50).

When using the function codes for setting a gain or bias alone without changing any reference points, the setting procedure for the function codes is the same as that of IMO's conventional inverter models.

F20 to F22 DC Braking (Starting frequency, Braking level, and Braking time)

These function codes enable the DC braking to prevent the motor from coasting due to its inertia while it is decelerating to a stop. Set function codes F20 for the starting frequency, F21 for the braking level, and F22 for the braking time.

The brake function of the inverter does not provide mechanical holding means.

Otherwise injuries could occur.

F23, F25 Starting Frequency and Stop Frequency

At the startup of an inverter, the initial output frequency is equal to the starting frequency. The inverter stops its output at the stop frequency.

Set the starting frequency to a level that will enable the motor to generate enough torque for startup. Generally, set the motor's rated slip frequency to F23.

㩷

If the starting frequency is lower than the stop frequency, the inverter will not output any power as long as the set frequency does not exceed the stop frequency.

Motor Sound (Carrier frequency and Tone)

 Motor Sound (Carrier frequency) (F26)

Carrier frequency 0.75 ĺ 15 kHz

Motor running noise Noisy ĺ quiet

Output current waveform Poor ĺ good

Leakage current level Low ĺ high

Changing the carrier frequency may decrease the motor running noise, leakage current from the output lines, and electric noise from the inverter.

Electric noise level Low ĺ high

5-25

Lowering the carrier frequency increases the ripple components (harmonic components) on the output current waveform so as to increase the motor's power loss and raises the temperature of the motor. If the carrie

frequency is set at 0.75 kHz, for example, estimate the motor output torque at 85% or less of the rated motor torque.

On the contrary, raising the carrier frequency increases the inverter’s power loss and raises the temperature of the inverter. The inverter has a built-in overload protection function that automatically decreases the carrier frequency to protect the inverter. For details about the function, refer to function code H98.

 Motor Sound (Tone) (F27)

Changes the motor running sound tone. This setting is effective when the carrier frequencies set to function code F26 is 7 kHz or lower. Changing the tone level may reduce the high and harsh running noise from the motor.

F30 F31

Terminal [FMA] (Gain to output voltage) Analogue Output Signal Selection for [FMA] (Monitor object)

F31 allows you to output monitored data (such as the output frequency or output current) to terminal [FMA] as an analogue DC voltage that can be adjusted with F30 for the meter scale.

 Adjusting the output voltage level (F30)

Adjust the output voltage level within the range of 0 to 200%, supposing the monitored amount of the monitor selected with function code F31 as 100%.

 Selecting object to be monitored (F31)

For three-phase 200V and single-phase 200V series of inverters

Outputting the output current in an analogue format (FMA) (F31 = 2)

Iref (A), supposing the output gain selected with F30 as

100%. For three-phase 200V and single-phase 200V series, therefore, you need to set the output gain (F30) based on the conversion result obtained by the following expression:

F43, F44

Current Limiter (Operation condition and Limiting level)

F43 enables or disables the current limiter. If it is enabled, the inverter controls the output frequency while keeping the current set to F44 in order to prevent the motor from stalling.

With F43, you may select whether the current limiter works during constant speed operation only (F43 = 1) or during both acceleration and constant speed operation (F43 = 2). Set F43 to 1, for example, to drive the motor at maximum performance in the acceleration zone and to limit the drive current in the constant speed zone.

For three-phase 200V and single-phase 200V series inverters The limiting level setting for the three-phase 200V and single-phase 200V

series should be calculated from the current limiting level



The reference current is given in the table for F20 to F22 on page 5-24.

• The current limiting feature selected by F43 and F44 are implemented by software, so an operational delay may occur. To avoid the delay, use the current limiter (hardware) simultaneously (H12 = 1).

• If an overload is applied when the limiting level is set extremely low, the inverter will immediately lower its output frequency. This ma

cause an overvoltage trip or dangerous turnover of the motor rotation due to undershooting.

If the current limiter function has been activated, the inverter may operate at an acceleration/deceleration time or frequen cy different from the set ones. The machine should be so designed that safety is ensured even in any current limiter operation.

Otherwise an accident could oc cur.

F50, F51

Electronic Thermal (Discharging capability and Allowable average loss)

These function codes configure the electronic thermal overload relay to protect the braking resistor from overheating.

Set the discharging capability and allowable average loss to F50 and F51, respectively. Those values differ depending upon the specifications of the braking resistor. Refer to the tables on the next page.

Depending on the discharging capability margin of a braking resistor, the electronic thermal function may operate and issue the overheat alarm "

dbH

," even if the actual temperature of the resistor is lower than that specified. Check braking resistor performance again and review the data setting of function codes F50 and F51.
