 Safety precautions

Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or maintenance and inspection. Ensure you have sound knowledge of the device and familiarize yourself with all safety information and precautions before proceeding to operate the inverter.

Safety precautions are classified into the following two categories in this manual.

Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in death or serious bodily injuries.

Failure to heed the information indicated by this symbol may lead to dangerous conditions, possibly resulting in minor or light bodily injuries and/or substantial property damage.

Failure to heed the information contained under the CAUTION title can also result in serious consequences. These safety precautions are of utmost importance and must be observed at all times.

Application

• FRENIC-Mini is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for other purposes.

Fire or an accident could occur.

• FRENIC-Mini may not be used for a life-support system or other purposes directly related to the human safety.

• Though FRENIC-Mini is manufactured under strict quality control, install safety devices for applications where serious accidents or material losses are foreseen in relation to the failure of it.

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.

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

Doing so could cause a drop of the inverter and 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.

Otherwise, a fire or an accident might result.

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

Doing so could cause fire, an accident or injuries.

• Do not get on 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)/a ground fault circuit interrupter (GFCI) (with overcurrent protection) in the path of power lines. Use the devices within the recommended current range.

• Use wires in the specified size.

• When wiring the inverter to the power supply of 500 kVA or more (50 kVA or more for the single-phase 115 V class series of inverters), be sure to connect an optional DC reactor (DCR).

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 output (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 following Class C or Class D specifications or national/local electric code, depending on the input voltage of the inverter.

Otherwise, electric shock could occur.

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

Otherwise, electric shock or injuries could occur.

• Ensure 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 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 or an accident.

iii

• Generally, control signal wires are not reinforced insulation. If they accidentally touch any of live parts in the main circuit, their insulation coat may break for any reasons. In such a case, an extremely high voltage may be applied to the signal lines. Make a complete remedy to protect the signal line from contacting any hot high voltage lines.

Doing so could cause an accident or electric shock.

• Wire the three-phase motor to terminals U, V, and W of the inverter, aligning phases each other.

Otherwise injuries could occur.

• The inverter, motor and wiring generate electric noise. Take care of malfunction of the nearby sensors and devices. To prevent the motor from malfunctioning, implement noise control measures.

Otherwise an accident could occur.

Operation

• Be sure to install the terminal block cover before turning the power on. Do not remove the cover while power is applied.

Otherwise electric shock could occur.

• Do not operate switches with wet hands.

Doing so could cause electric shock.

• If the retry function has been selected, the inverter may automatically restart and drive the motor depending on the cause of tripping.

(Design the machinery or equipment so that human safety is ensured after restarting.)

• If the stall prevention function (current limiter), automatic deceleration, and overload prevention control have been selected, the inverter may operate at an acceleration/deceleration time or frequency different from the set ones. Design the machine so that safety is ensured even in such cases.

Otherwise an accident could occur.

• The STOP key is only effective when function setting (Function code F02) has been established to enable the STOP key. Prepare an emergency stop switch separately. If you disable the STOP key priority function and enable operation by external commands, you cannot emergency-stop the inverter using the STOP key on the built-in keypad.

• If an alarm reset is made with the operation signal turned on, a sudden start will occur. Ensure that the operation signal is turned off in advance.

Otherwise an accident could occur.

• If you enable the "restart mode after momentary power failure" (Function code F14 = 4 or

5), then the inverter automatically restarts running the motor when the power is recovered.

(Design the machinery or equipment so that human safety is ensured after restarting.)

• If you set the function codes wrongly or without completely understanding this instruction manual and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.

An accident or injuries could occur.

• Do not touch the inverter terminals while the power is applied to the inverter even if the inverter stops.

Doing so could cause electric shock.

• Do not turn the main circuit power on or off in order to start or stop inverter operation.

Doing so could cause failure.

• Do not touch the heat sink or braking resistor because they become very hot.

Doing so could cause burns.

• Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting, check the specifications of the motor and machinery.

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

Injuries could occur.

Wiring length for EMC filter built-in type

• When the wiring length between the inverter and motor exceeds 33ft(10 m), the filter circuit may be overheated and damaged due to increase of leakage current. To reduce the leakage current, set the motor sound (carrier frequency) to 2 kHz or below with function code F26.

Otherwise a failure could occur.

Installation and wiring of an option card

• Before installing an RS-485 Communications Card, turn off the power, wait more than five minutes, and make sure, using a circuit tester or a similar instrument, that the DC link bus voltage between the terminals P (+) and N (-) has dropped below a safe voltage (+25 VDC).

• Do not remove the terminal cover for the control circuits while power is applied, because high voltage lines exist on the RS-485 Communications Card.

Failure to observe these precautions could cause electric shock.

• In general, sheaths and covers of the control signal cables and wires are not specifically designed to withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the cover might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure that the control signal cables and wires will not come into contact with live conductors of the main circuits.

Failure to observe these precautions could cause electric shock and/or an acci-

dent.

Maintenance and inspection, and parts replacement

• Turn the power off and wait for at least five minutes before starting inspection. Further, check that the LED monitor is unlit, and check the DC link bus voltage between the P (+) and N (-) terminals to be lower than 25 VDC.

Otherwise, electric shock could occur.

• Maintenance, inspection, and parts replacement should be made only by qualified persons.

• Take off the watch, rings and other metallic matter before starting work.

• Use insulated tools.

Otherwise, electric shock or injuries could occur.

Disposal

• Handle the inverter as an industrial waste when disposing of it.

Otherwise injuries could occur.

Others

• Never attempt to modify the inverter.

Doing so could cause electric shock or injuries.

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 2006/95/EC.

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

* With overcurrent protection.

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

3. When you use a residual-current-operated protective device (RCD)/ a ground fault circuit interrupter(GFCI) for protection from electric shock in direct or indirect contact power lines or nodes, be sure to install type B of RCD/GFCI on the input (primary) of the inverter if the power source is three-phase 230/460 V. For single-phase 230 V power supplies, use type A.

When you use no RCD/GFCI, 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 230 V class series of inverters to the power supply in Overvoltage Category III or to connect the three-phase 460 V class series of inverters to the power supply in Overvoltage Category II or III, a supplementary insulation is required for the control circuitry.

9. When using inverters at an altitude of more than 6600ft(2000m), note that the basic insulation applies to the insulation degree of the control circuitry. At an altitude of more than 9900ft(3000m), inverters cannot be used.

10. The power supply mains neutral has to be earthed for the three-phase 460 V class inverter.

In running special motors

Submersible motors and pumps

Brake motors

When driving a 460 V 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. Fuji motors do not require the use of output circuit filters because of their good insulation.

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 a Fuji inverter motor or a motor equipped with an externally powered ventilating fan.

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).

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.

If the reference 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.

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

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.

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

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

Installing an MC in the secondary circuit

Installing an MC in the primary circuit

Protecting the motor

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.

It is necessary to take special measures suitable for this motor type. Contact your Fuji Electric representative for details.

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, us

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

Use the inverter within the ambient temperature range from

-10 to +50C(14 to 122°F). 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."

Install a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/a ground fault circuit interrupter(GFCI)(with overcurrent protection) in the input (primary) circuit of the inverter to protect the wiring. Ensure that the circuit breaker capacity is equivalent to or lower than the recommended capacity.

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 united with a surge killer to the inverter's secondary circuit.

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

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

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).

Do not mount power-factor correcting capacitors in the inverter’s 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.

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

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

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 65ft (20m) or less and use twisted pair or shielded cable.

If long wiring is used between the inverter and the motor, the

Wiring length between inverter and motor

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 164ft (50m). If this length must be exceeded, lower the carrier frequency or mount an output circuit filter (OFL).

Wiring size

Wiring type

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

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

Grounding Securely ground the inverter using the grounding terminal.

Select an inverter according to the nominal applied motor

Driving general-purpose motor

Driving special motors

When exporting an inverter built in a panel or equipment, pack them in a previously fumigated wooden crate. Do not fumigate them after packing since some parts

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.

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

inside the inverter may be corroded by halogen compounds such as methyl bromide used in fumigation.

When packing an inverter alone for export, use a laminated veneer lumber (LVL). For other transportation and storage instructions, see Chapter 1, Section 1.3

"Transportation" and Section 1.4 "Storage Environment."

1.3 Transportation

• When carrying the inverter, always support its bottom at the front and rear sides with both hands. Do not hold covers or individual parts only. You may drop the inverter or break it.

• Avoid applying excessively strong force to the terminal block covers as they are made of plastic and are easily broken.

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

Relative humidity

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

Atmospheric pressure

Assuming 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).

-25 to +70℃(-4 to +158°F)

5 to 95%

gases, oil mist, vapor, water drops or vibration. The atmosphere can contain only a low level of salt. (0.01 mg/cm2 or less per year)

86 to 106 kPa (in storage)

70 to 106 kPa (during transportation)

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

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 (14 to 86°F) .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 specified in Table 1.1.

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.

2.3.4 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 as possible from each other.

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or residual-current-operated protective device (RCD)/ a ground fault circuit interrupter(GFCI)(with overcurrent protection) (with overcurrent protection) 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 output (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 following Class C or Class D specifications or national/local electric code, depending on the input voltage of the inverter.

Otherwise, electric shock could occur.

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

Otherwise, electric shock or injuries could occur.

• Ensure 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.

2.3.7 Wiring for control circuit terminals

In general, sheaths and covers of the control signal cables and wires are not specifically designed to withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the cover might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure that the control signal cables and wires will not come into contact with live conductors of the main circuit.

Failure to observe these precautions could cause electric shock and/or an accident.

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.

- Since weak analog signals are handled, these signals are especially susceptible to the external noise effects. Route the wiring as short as possible (within 65ft/20 m) and use shielded wires. In principle, ground the shielding layer of the shielded wires; if effects of 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 control 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.

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 power factor correcting 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 power factor correcting 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 noise filter to the inverter power wires.

- Isolate the power system of the other devises from that of the inverter with an insulated 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 on the metal switchboard and connect the whole board to the ground.

- Connect a noise filter to the inverter power wires.

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

- For the control signal wires, use twisted or shielded-twisted wires. When 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 insulated gate bipolar transistors (IGBTs) switching on/off inside the inverter becomes 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 2.8 Leakage Current Countermeasures

Problem Measures

1) Decrease the carrier frequency.

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

3) Use an earth leakage circuit breaker (a ground fault circuit interrupter) with lower sensitivity than the one currently used.

4) Use an earth leakage circuit breaker (a ground fault circuit interrupter) that features measures against harmonic component (Fuji SG and EG series).

1) Decrease the carrier frequency.

2) Increase the settling current of the thermal relay.

3) Use the thermal relay built in the inverter.

 Displaying I/O signal status in hexadecimal format

Each I/O terminal is assigned to bit 15 through bit 0 as shown in Table 3.17. An unassigned bit is interpreted as "0." Allocated bit data is displayed on the LED monitor in 4 hexadecimal digits ("0" to "F" each).

With the FRENIC-Mini, 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 bit is set to "1" when the corresponding input terminal is short-circuited with terminal [CM] or terminal [PLC] *, and is set to "0" when it is open. For example, when [FWD] and [X1] are on (short-circuited) and all the others are off (open), "0005" is displayed on LED4 to LED1.

* Terminal [CM] if the jumper switch is set for a sink; terminal [PLC] if the jumper switch is set for a source.

Digital output terminal [Y1] is assigned to bit 0. Bit 0 is set to "1" when this terminal is short-circuited with [Y1E], and to "0" when it is open. The status of the relay contact output terminal [30ABC] is assigned to bit 8. It is set to "1" when the circuit between output terminals [30A] and [30C] is closed and to "0" when the circuit between [30B] and [30C] is closed. For example, if [Y1] is on and [30A] is connected to [30C], then "0101" is displayed on the LED4 to LED1.

Table 3.17 presents an example of bit assignment and corresponding hexadecimal display on the 7-segment LED.

frequency.

(2) With the built-in potentiometer clockwise, set a low frequency such as 5 Hz. (Check that the

frequency displayed on the LED monitor blinks.)

(3) Press the key to start running the motor in the forward direction. (Check that the reference

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 reference frequency.

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

Chapter 5 FUNCTION CODES

5.1 Function Code Tables

Function codes enable the FRENIC-Mini 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

Y* Possible

Y Possible

N Impossible —

 Copying data

Connecting a remote keypad (option) to an inverter via the RS-485 communications card (option) 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. (The function code marked "N" is not subject to the Verify operation, either.)

It is recommended that you set up those function codes which are not subject to the Copy operation

individually using Menu #1 "Data setting" as necessary.

Refer to the Remote Keypad Instruction Manual for details.



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.

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.

Validating and saving function code data

5-1

 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 code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An active-ON signal (the function takes effect if the terminal is short-circuited.) in the normal logic system is functionally equivalent to active-OFF signal (the function takes effect if the terminal is opened.) in the negative logic system. An active-ON signal can be switched to active-OFF signal, and vice versa, with the function code data setting.

To set the negative logic system for an I/O terminal, enter data of 1000s (by adding 1000 to the data for the normal logic) in the corresponding function code. Some signals cannot switch to active-OFF depending upon their assigned functions.

Example: "Coast to a stop" command BX assigned to any of digital input terminals [X1] to [X3] using any of function codes E01 through E03

Function code data BX

7 Turning BX ON causes the motor to coast to a stop. (Active ON)

1007 Turning BX OFF causes the motor to coast to a stop. (Active OFF)

 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.

F02

Operation Method

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 RE V 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 signal 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 RE V 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 and 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.

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

 Rated voltage at base frequency (F05) 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.

 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.)

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. (For the single-phase 100 V class series, setting the voltage that is two times or more the inverter's input source voltage is not allowed.)

You can also set the optional nonfrequencies exceeding the base frequency (F40).

The acceleration time specifies the length of time the frequency increases from 0 Hz to the maximum frequency. The deceleration time specifies the length of time the frequency decreases from the maximum frequency down to 0 Hz.

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 (variable torque or constant torque characteristics) with Load Selection (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.

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.

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.
