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-Lift is equipment designed to drive induction motors and synchronous motors for exclusively controlling elevating machinery. Do not use it for single-phase motors or for other purposes.

Fire or accident could occur.

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

• Though FRENIC-Lift 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.

• Using an optional DC reactor makes human body easily touch any live parts of inverters. In this case, take countermeasures such as installing the inverter in a place that easily protects human body from electric shock.

Otherwise, electric shock or injuries could occur.

• Do not touch the printed circuit boards in the product directly. Electronic devices on those boards are easily affected by static electricity.

When touching those boards, put on a grounding wrist band and perform the job on a static mat.

Static electricity charged in your body may damage the product.

• 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)/earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of power lines. Use the devices within the recommended 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.

• Install inverters in compliance with the local regulation.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

Otherwise fire or an accident could occur.

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

Doing so could cause fire or an accident.

• Generally, control signal wires are not enforced-insulated. If they accidentally touch any live power lines, 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 live high voltage lines.

Otherwise, an accident or electric shock could occur.

• 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

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 commanded ones. Design the machine so that safety is ensured even in such cases.

Otherwise an accident could occur.

• If an alarm reset is made with the Run command signal turned ON, a sudden start will occur. Ensure that the Run command signal is turned OFF in advance.

Otherwise an accident could occur.

• If you set the function codes wrongly or without completely understanding this instruction manual and the FRENIC-Lift Reference Manual (INR-SI47-1068-E), the motor may rotate with a torque or at a speed not permitted for the machine.

• In the tuning process of the inverter, no motor torque control for braking of the machinery takes effect. Tune the inverter for the motor after disconnecting it from the machinery, or after mechanically brakes the machinery. Anyway, do it after suppressing any dangerous factors.

An accident or injuries could occur.

• Never touch the inverter terminals while the power is applied to the inverter even if the inverter stops.

• Never touch the printed circuit boards in the product while the power is applied to the inverter. High voltage is applied to those boards.

Doing so could cause electric shock.

iii

• Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop inverter operation.

Doing so could cause failure.

• Do not touch the heat sink 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.

Setting control switches

• Before setting up any internal control switches, turn OFF the power, and wait for more than five minutes. Further, check that the LED monitor is unlit, and make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P (+) and N (-) has dropped below a safe voltage (+25 VDC).

Otherwise electric shock could occur.

GENERAL PRECAUTIONS

 Precautions for use

In running generalpurpose motors

In running special motors

Driving a 400V general-purpose motor

Torque characteristics and temperature rise

Vibration

Noise

Brake motors

Geared motors

When driving a 400V general-purpose motor with an inverter using extremely long wires, damage to the insulation of the motor may occur. Apply the inverter after consulting the motor maker.

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.

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 recom-

mended.

* Run your machinery including FRENIC-Lift inverter so as to skip its re-

sonance 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.

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 output circuit by mistake, the brake will not work.

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

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.

Environmental conditions

Synchronous motors

Single-phase motors

Installation location

The PG interface card (option) corresponding to the pulse encoder specfication is necessary. Read PG interface card (option) manual.

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

Use the inverter within the ambient temperature range from -10 to +45°C.

The heat sink and braking resistor of the inverter may become 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 resi-

Installing an MCCB or RCD/ELCB

dual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection) 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.

Combination with peripheral devices

Installing an MC in the secondary circuit

Installing an MC in the primary circuit

Protecting the motor

Discontinuance of power-factor correcting capacitor

Discontinuance of surge killer

Reducing noise

If a magnetic contactor (MC) is mounted in the inverter's output (secondary) circuit, ensure that both the inverter and the motor are completely stopped before you turn the MC on or off.

Remove a surge killer built-in the MC.

Do not turn the magnetic contactor (MC) in the 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.

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.

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’s output (secondary) circuit. An overcurrent trip will occur, disabling motor operation.

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

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

Wiring

If an overvoltage trip occurs while the inverter is stopped or operated under

Measures against surge currents

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.

When checking the insulation resistance of the inverter, use a 500 V

Megger test

megger and follow the instructions contained in Chapter 7, Section 7.5 "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 pair or shielded wire.

If long wiring is used between the inverter and the motor, the inverter will Wiring length between inverter and motor

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 20 m. If this length must be exceeded, lower

the carrier frequency.

Wiring size

Wiring type

Select wires with a sufficient capacity by referring to the current value or

recommended wire size.

When several inverters drive motors, 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

Transportation and storage

Select an inverter according to the applicable motor ratings listed in the

Driving general-purpose motor

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.

Driving special motors

Select an inverter that meets the following condition:

Inverter rated current > Motor rated current

Halogen compounds such as methyl bromide used in fumigation corrodes some parts inside the inverter. When exporting an inverter built in a panel or equipment, pack them in a previously fumigated wooden crate. When packing an inverter alone for export, use a laminated veneer lumber (LVL).

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."

1.3 Transportation

• When carrying an 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.

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 *1 -25 to +65°C Relative humidity 5 to 95% *2

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

Atmospheric pressure 86 to 106 kPa (in storage)

70 to 106 kPa (during transportation)

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

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

or less per year)

(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 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.

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) 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 or othe dustproof containers.

(Note 2) If you use the inverter in an altitude above 1000 m, you should appl an output current derating factor as listed in Table 2.2.

Top 100 mm

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 your system, take extra care with ventilation inside the enclosure as the temperature around the inverter will tend to increase. Do not install the inverter in a small enclosure with poor ventilation.

Further,

do not install two or more inverters in single equipment or in

an enclosure.

Figure 2.1 Mounting Direction and

Required Clearances

 When employing external cooling

t the shipment time, the inverter is set up for mount inside your

equipment or enclosure so that cooling is done all internally.

To improve cooling efficiently, you can take the heat sink out of the equipment or the enclosure (as shown on the right) so that cooling is done both internally and externally (this is called "external cooling").

To set up inverters with a capacity of 22 kW or below for "external cooling," add the optional mounting adapter; to set up ones with a capacity of 30 kW or above, change the position of the top and bottom mounting bases as shown below.

 For details about the optional mounting adapter, refer to the

Mounting Adapter for External Cooling "PB-F1" Installation Manual (INR-SI47-0880).

In external cooling, the heat sink, which dissipates about 70% of the total heat (total loss) generated into air, is situated outside the equipment or the enclosure. As a result, much less heat is

Figure 2.2 External Cooling

radiated inside the equipment or the enclosure.

In an environment with high humidity or a lot of fibrous dust, however, do not use external cooling, which tends to clog the heat sink.

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.

To utilize external cooling for inverters with a capacity of 30 kW

, change the position of the top and bottom

mounting bases from the edge to the center of the inverter as instructed on the next page.

Screws differ in size, length and count for each inverter. Be sure to refer to the table below.

(3) Mounting direction

Horizontal layout is recommended when two or more inverters are to be installed in an equipment 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.

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.

(4) Solving abnormal vibration after installation

If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling fan(s) or the keypad, fix them firmly using the fixing screws provided as accessories.

2.3.5 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 three-phase power wires to the main circuit power input terminals L1/R, L2/S and

L3/T 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 earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair of power lines to inverters. Use the devices recommended ones within the related current range.

• Use wires in the specified size.

• Tighten terminals with recommended torque.

Otherwise, fire could occur.

• Use a multi-core power cable (3- or 4-wires) to wire the inverter with a motor.

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

Doing so could cause fire.

• According to the input power series install FRENIC-Lift in compliance with local regulations.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

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

Otherwise, electric shock could occur.

• Be sure to perform wiring after installing the inverter.

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.

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

Doing so could cause fire or an accident.

Grounding terminals ( G)

Be sure to ground either of the two grounding terminals for safety and noise reduction.

Install FRENIC-Lift in compliance with the local regulations, Described below for an example, a procedure shows an installation of the inverter in compliance with regulations in Japan.

E.g. grounding terminals should be grounded as follows:

1) For the 200 V or 400 V series of inverters, connect the grounding terminal to a ground electrode on which class D or C grounding work has been completed, respectively, with conformity to 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 2.11. Keep the wiring length as short as possible.

Inverter output terminals, U, V, W and grounding terminals ( G)

Inverter’s output terminals should be connected as follows:

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

2) Connect the secondary grounding wire to the grounding terminal (

• The wiring length between the inverter and motor should not exceed 50 m, when they are connected directly.

• Do not connect a power factor correcting capacitor or surge absorber to the inverter’s output lines (secondary circuit).

• 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.

• Do not drive two or more motors by single inverter.

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, lower the carrier frequency (Function code F26: Motor sound (Carrier frequency)).

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

- Use a motor with insulation that withstands the surge voltage.

- Minimize the wiring length between the inverter and motor.

DC reactor terminals, P1 and P (+)

G).

1) Remove the short bar from terminals P1 and P(+).

2) Connect a DC reactor (option) to terminals P1 and P(+).

• The wiring length should be 10 m or below.

• Do not remove the short bar installed across P1 and P(+) terminals if a DC reactor is not to be used.

2-15

DC link bus terminals, P (+) and N (-)

These are provided for the DC link bus powered system. Connect these terminals with terminals P(+) and N (-) of an optional regenerative converter or the equivalent.

Consult your Fuji Electric representative if these terminals are to be used.

1) For safety, make sure that the molded case circuit breaker (MCCB) or magnetic contactor (MC) is turned off

2) Connect the main circuit power supply wires (L1/R, L2/S and L3/T or L1/L, L2/N (single-phase )) to the input

It is not necessary to align phases of the power supply wires and the input terminals of the inverter with

each other.

* With overcurrent protection

It is recommended that a magnetic contactor be inserted that can be manually activated. This is to allow you to disconnect the inverter from the power supply in an emergency (e.g., when the protective function is activated) so as to prevent a failure or accident from causing the secondary problems.

Auxiliary power input terminals R0 and T0 for the control circuit

For the models of single-phase 200V, 200V series 22kW or below, and 400V series 30kW or below

In general, the inverter will run normally without power supplied to the auxiliary power input for the control circuit. However, if you share the input power for the control circuit with that for the main circuit, you would be lost when, in the event of an error or alarm, you turn OFF the magnetic contactor between the inverter and the commercial power supply. If the magnetic contactor is turned OFF, the input power to the control circuit is shut OFF, causing the alarm signals (30A/B/C) to be lost and the display on the keypad to disappear. To secure input power to the control circuit at all times, supply the power from the primary side of the magnetic contactor to control power auxiliary input terminals R0 and T0. The method of connecting auxiliary power input terminals for the control circuit refer to Section 2.3.8 "Setting up slide switches."

For the models of 400 V series 37 kW or above

The inverter will not run normally without power supplied to the auxiliary power input for the control circuit. However, if you share the input power for the control circuit with that for the main circuit, you would be lost when, in the event of an error or alarm, you turn OFF the magnetic contactor between the inverter and the commercial power supply. If the magnetic contactor is turned OFF, the input power to the control circuit is shut OFF, causing the alarm signals (30A/B/C) to be lost and the display on the keypad to disappear. To secure input power to the control circuit at all times, supply the power from the primary side of the magnetic contactor to control power auxiliary input terminals R0 and T0. The method of connecting auxiliary power input terminals for the control circuit refer to Section 2.3.8 "Setting up slide switches."

When the DC power input is used, auxiliary power input terminals is used. The connected AC power is:

Single phase 380 to 460 V/50 Hz or 60 Hz for 400 V series 37 kW or above

Note: Allowable power input voltage range should be within – 15% to +10% of power source voltage.

Connect the power supply with R0 and T0 if the inverter of 37 kW or above is used, and the main power supply is connected.

If you do not connect the power supply with Auxiliary power input terminals, the cooling fan will not run, causing a heat sink overheating alarm "

0h1

" or a charger circuit error alarm "

Braking resistor connection terminals, P(+) and DB

1) Connect terminals P and DB of an external 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.

Power switching connectors [CN UX] (for the models of 400 V series 37 kW or above)

An inverter of 400 V series 37 kW or above is equipped with a set of switching connectors CN UX (male) which should be configured with a jumper according to the power source voltage and frequency. Set the jumper to U1 or U2 depending upon the power source voltage applied to the auxiliary power input terminals (R0, T0), as shown in Figure 2.13. Power switching connectors [CN UX] is arranged in the power supply printed wiring board in the right part of the control printed wiring board. Please refer to figure 2.12 and Figure 2.13 for details.

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.

Table 2.13 lists the symbols, names and functions of the control circuit terminals. The wiring to the control circuit terminals differs depending upon the setting of the function codes, which reflects the use of the inverter.

Analog common

Two common terminals for analog input and output signal terminals [12], [C1], and [V2].

These terminal are electrically isolated from terminals [CM]s and [CMY].

- Since low level analog 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 of external inductive noises are considerable, connection to terminal [11] may be effective. As shown in Figure 2.15, ground the single end of the shield to enhance the shielding effect.

- Use a twin contact relay for low level 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 components between control signal wires as shown in Figure 2.16.

- Do not apply a voltage of +7.5 VDC or higher to terminal [C1]. Doing so could damage the internal control circuit.

2.3.8 Setting up slide switches

Before setting up any internal control switches, turn the power OFF. For the inverters with a capacity of 22 kW or below, wait at least 5 minutes; for the inverters with a capacity of 30 kW or above, wait at least 10 minutes. Further, check that the charge lamp is unlit, and make sure that the DC link bus voltage between the terminals P(+) and N(-) has dropped below a safe voltage (+25 VDC) using a multimeter or a similar instrument.

An electric shock may result if this warning is not heeded as there may be some residual electric charge in the DC link bus capacitor even after the power has been turned off.

 Setting up the slide switches

To switch the slide switches, remove the front and terminal block covers, so that you can access the control PCB that contains the switches.

 For details of removing the front cover, terminal block cover, and dummy cover, refer to Section 2.3.1

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

(1) Harmonic component

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

- Install the inverter onto 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 wire sheath shield to the common terminals of the control circuit or ground.

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

2-28

(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 an appropriate measure against them.

Table 2.15 Leakage Current Countermeasures

Problem Measures

An earth leakage circuit breaker* that is connected to the input (primary) has tripped.

* With overcurrent protection

An external thermal relay was activated.

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 longer sensitive current than one currently being used.

4) Use an earth leakage circuit breaker 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 electronic thermal motor overheat protection built in the inverter, instead of an external thermal relay.

Chapter 4 RUNNING THE MOTOR

4.1 Running the Motor for a Test

4.1.1 Inspection and preparation prior to powering on

(1) Check if connection is correct.

Especially check if the power wires are connected to the inverter input terminals L1/R, L2/S and L3/T or L1/L, L2/N,

and output terminals U, V and W respectively and that the grounding wires are connected to the ground electrodes correctly. Note that FRENIC-Lift series is designed for three phase input and driving three phase motors.

• 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) Make sure that the switches are OFF so that

the inverter 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 unexpectedly approaching

Figure 4.1 Connection of Main Circuit Terminals

your power system.

(7) Make sure that the signal wires from the pulse encoder mounted on the motor or external equipment are

connected to control signal input terminals (PA, PB, PO, CM and PZ if any) correctly.

(8) Make sure that the power source voltage (P0) to the pulse encoder satisfies the specifications.

4.1.2 Turning ON power and checking

• Be sure to install the covers for both the main circuit terminal block, control circuit terminal block and the front cover if any before turning the power ON.

Do not remove any cover while powering on.

• Do not operate switches with wet hands.

Otherwise electric shock could occur.

Turn the power ON and check the following points. The following assumes that no function code data is changed from the factory defaults.

(1) Check if a built-in cooling fan rotates.

(The cooling fan does not rotate if the control power only is supplied while the main power is shut down.)

4-1

4.1.3 Preparation before running the motor for a test--Setting function code data

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.

To set up function code, you need to use the multi-function keypad (option) or to access their data via



communications link. For details of the multi-function keypad and communications link, refer to the Multi-function Keypad Instruction Manual (INR-SI47-1092-E) and RS485 Communications FRENIC-Lift Reference Manual (INR-SI47-1068-E) respectively. For the factory defaults for the motor parameter, refer to the Chapter 5 “ Appendix Factory Defaults ". If the parameter for your motor differs from the default, change it by using the function code.

Apply this step if parameters of the no load current and rated slip are known.

Apply this step if parameters of the no load current and rated slip are unknown.

Upon completion of the tuning, the primary resistance %R1 will be automatically saved into P07, the leakage reactance %X into P08, the no-load current into P06, and .the rated slip into P12.

3) Preparation of Machine System

Perform appropriate preparations on the motor and its load, such as disengaging the coupling and deactivating the safety device.

4) Perform tuning

Set function code P04 to "1" or "2" and press the key.

Tuning takes place while the motor is stopped.

(Time for the tuning: Around 15 seconds max. if P04 = 1, 25 seconds max. if P04 = 2)

"Command off" is displayed on the LCD screen of a multi-function keypad.

The Run command is turned OFF and the tuning completes, with the next function code P06 displayed on

the multi-function keypad. (the Run command given through the keypad or the communications link is automatically turned OFF).

In the tuning process of the inverter, no motor torque control for braking of the machinery takes effect. Tune the inverter for the motor after disconnecting it from the machinery, or after setting mechanical brake of the machinery. Anyway, do it after suppressing any dangerous factors.

An accident or injuries could occur.

Tuning of the motor parameter using the function code H04 is exclusively designed for induction motors. Do not apply this to any synchronous motors.

4-3

 Errors during tuning

Improper tuning would negatively affect the operation performance and, in the worst case, could even cause hunting or deteriorate precision. Therefore, if the inverter finds any abnormality in the results of the tuning or any error in the process of the tuning, it will display

er7

and discard the tuning data.

Listed below are the abnormal or error conditions that can be recognized during tuning.

Abnormal/error condition Description

Abnormal result of tuning

Abnormal output current

Sequence error

Limitation exceeded

Other alarm condition

An inter-phase imbalance has been detected;

Tuning has resulted in an abnormally high or low value of a parameter.

An abnormally high current has been caused during tuning.

This will occur during tuning if the run command/EN terminal input/forced-to-decelerate terminal command DRS turns off, or the coast-to-stop terminal command BX turns on, where status of DRS and BX is expressed in normal logic.

During tuning, a certain limitation has been reached or exceeded;

The maximum output frequency or the peak limiter for output frequency has been reached or exceeded.

An undervoltage or an alarm has been occurred.

If any of these conditions has occurred, either eliminate the abnormal or error factor(s) and perform tuning again, or contact your Fuji Electric representative.

 Tuning offset angle of the magnet pole

Before to proceed to running a synchronous motor, be sure to tune offset angle of the magnet pole. For the tuning procedure, refer to the instruction manual of the option card.

To apply a synchronous motor, use the option card in a separate ordering. For details, refer to the



instruction manual of the option card.

Running a synchronous motor without tuning of the offset angle may result in an unexpected operation.

An accident or injuries could occur.

4.1.4 Test run

If the user set the function codes wrongly or without completely understanding this Instruction Manual and the

FRENIC-Lift Reference Manual (INR-SI-47-1068-E), 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 powering on" to Section 4.1.3, "Preparation before running the motor for a test," and begin test-driving of the motor.

Turn on the terminal [EN] before running the motor.

If sink/source change switch (SW1) is a sink side, connect terminal [EN] and terminal [CM].

If sink/source change switch (SW1) is a source side, connect terminal [EN] and terminal [PLC].

If terminal [EN] and [CM] don’t connect, the motor doesn’t rotate.

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

4.2 Operation

After confirming ordinary operation by performing a test run, make mechanical connections (connections of the machine system) and electrical connections (wiring and cabling), and set the necessary parameters properly before starting a production run.

Before to proceed running the inverter in operations check the related function code data again and reconfigure it if needed.

Chapter 5 FUNCTION CODES

5.1 Function Code Tables

Function codes enable the FRENIC-Lift 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) (C codes)

, Motor Parameters (P codes), High Performance Functions (H codes), Link Function (y codes) and Lift Functions (L codes). For details of function codes, refer to the FRENIC-Lift Reference Manual (INR-S147-1068-E). 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



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

, Extension Terminal Functions (E codes), Control Functions

Y* Possible

Y Possible

N Impossible —

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 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



Copying data

Connecting the multi-function keypad (option) to an inverter via the RS485 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 copying" 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.)

For details of how to set up or edit function codes, refer to the Multi-function Keypad "TP-G1-CLS" Instruction Manual (INR-S147-1092-E.)

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 using function code E01

Function code data

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)

 Description on the control mode of FRENIC-Lift

FRENIC-Lift runs in following control modes

A: Vector control with PG (asynchronous motor)

B: Vector control with PG (synchronous motor)

C: V/f control (asynchronous motor)

D: Torque vector control (asynchronous motor)

You can select the control mode between them combining data of function codes, F42 and H18, and the terminal command PG/Hz as listed below.

F42 H18 PG/Hz *1 Selected control mode

0 0 ON

0 0 OFF

0 1 ON

0 1 OFF

1 0 ON

1 0 OFF

1 1 ON

1 1 OFF

2 0 / 1 ON / OFF

*1 ON/OFF state is expressed in the normal logic. If no terminal command is assigned to any terminals, then the default

value is ON.

*2 An optional card is needed in a separate ordering. For details of operation, refer to the instruction manual of the optional

card.

*3 Apply this only for a test run. Do not apply this for the inverter in operations. Note that in this mode the inverter may not

run in normal performance depending on a running condition.

When the version that the torque vector control doesn't correspond is used, it becomes V/f control (asynchronous motor)/speed control. V/F control setting should apply to a test run only. Applying the setting to an inverter operation with an actual load is dangerous. With this setting, the inverter may not run in sufficient performance depending upon running conditions.

• The torque vector control is available from 4.0 to 22kW of 400V series. Please do not use it with other products.

Otherwise injuries could occur.

In the torque control, data of some function codes related to the control may be enabled or disabled. Marks to classify these

situations in the torque control column of the function code table on the following pages as shown below.

Y: Code data is enabled and affects the inverter operations.

N: Code data is disabled and does not affect the inverter operations.

 Function Codes Requiring Modification

Specifying Order of Function Codes

Function codes C21 (Speed Command Unit) and P01 (Motor, No. of poles) should be specified preceding other function codes. This is because depending upon those code data, the setting ranges and units of some function codes differ as listed below.

Next, F03 (Maximum Speed) and L31 (Elevator Parameter, Speed) should be specified.

Changing any data of C21, P01, F03 and L31 requires modifying the data of the function codes listed below again.

Function Codes Requiring Modification

F04 (Rated Speed)

F20(DC Braking Starting Speed)

F23 (Starting Speed)

C21

Depending upon the data of C21 (Speed Command Unit), the setting ranges and units of the function codes listed at the right differ.

F03 or L31 (when C21 = 1)

Depending upon the data of F03 (Maximum Speed) or L31 (Elevator Parameter, Speed) when C21 = 1, the setting ranges of the function codes listed at the right differ.

P01

Depending upon the data of P01 (Motor, No. of poles), the setting ranges of the function codes listed at the right differ.

F25 (Stop Speed)

E30 (Speed Arrival, Hysteresis)

E31 (Speed Detection, Detection level)

E32 (Speed Detection, Hysteresis)

C03 (Battery Operation Speed)

C04 (Zero Speed) to C11 (High Speed)

C20 (Jogging speed)

H74 (Speed Agreement, Hysteresis)

L30 (Short Floor Operation, Allowable speed)

L40 (ASR, Switching speed 1)

L41 (ASR, Switching speed 2)

L87 (Door Control, Door open starting speed)

Function codes listed above plus

F03 (Maximum Speed)

When configuring function codes, observe the following order.

ROM version Configuration order

0300, 0500 C21→P02→P01→F03→L31→Other function codes

Other versions C21→P01→F03→L31→Other function codes

Note: The setting ranges and units of the function codes in this manual are mentioned, based on the factory defaults

of C21 and P01, that is, C21 = 0 (r/min) and P01 = 4 (4 poles).

Chapter 6 TROUBLESHOOTING

6.1 Before Proceeding with Troubleshooting

If any of the protective functions have been activated, first remove the cause. Then, after checking that the all run commands are set to off, reset the alarm. Note that if the alarm is reset while any run commands are set to on, the inverter may supply the power to the motor which may cause the motor to rotate.

Injury may occur.

- Even though the inverter has interrupted power to the motor, if the voltage is applied to the main circuit power input terminals L1/R, L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.

- Before setting up any internal control switches, turn the power OFF. For the inverters with a capacity of 22 kW or below, wait at least 5 minutes; for those with a capacity of 30 kW or above, wait at least 10 minutes. Further, check that the charge lamp is unlit and make sure that the DC link bus voltage between the terminals P (+) and N (-) has dropped below the safe voltage level (25 VDC) using a multimeter or a similar instrument.

Electric shock may occur.

wait more than five minutes for models of 30 kW or below, or ten minutes for models of 37 kW or above.

Follow the procedure below to solve problems.

(1) First, check that the inverter is correctly wired, referring to Chapter 2, Section 2.3.6 "Wiring for main circuit

terminals and grounding terminals."

(2) Check whether an alarm code is displayed on the LED monitor.

If any problems persist after the above recovery procedure, contact your Fuji Electric representative.

[ 1 ]

n Overcurrent

Problem The inverter momentary output current exceeded the overcorrect level. OC1

Overcurrent occurred during acceleration. OC2 Overcurrent occurred during deceleration. OC3 Overcorrect occurred when running at a constant speed.

Possible Causes What to Check and Suggested Measures

(1) The inverter output

terminals were short-circuited.

Remove the wires connected to the inverter output terminals (U, V, and W) and measure the interphase resistance of the wires. Check if the resistance is too low.

Î Remove the part that short-circuited (including replacement of the wires,

relay terminals and motor).

(2) Ground faults occurred at

the inverter output terminals.

Remove the wires connected to the inverter output terminals (U, V, and W) and perform a Megger test.

Î Remove the part that short-circuited (including replacement of the wires,

relay terminals and motor).

(3) Loads were too heavy. Measure the motor current with a measuring device, and to trace the current

trend. Therefore, use this information to judge if the trend is over the calculated load value for your system design.

ÎIf the load is too heavy, change the inverter for an upper size.

Trace the current trend and check if there are any sudden changes in the current.

Î Change the inverter for an upper size.

6-7

Possible Causes What to Check and Suggested Measures

(4) The acceleration/

deceleration time was too short.

Check that the motor generates enough torque required during acceleration/deceleration. That torque is calculated from the moment o inertia for the load and the acceleration/deceleration time.

Î Increase F07, F08, and E10 to E17 (Acceleration/Deceleration Time). Î Change the inverter for an upper size.

(5) A high intensity noise was

given to the inverter.

Check if noise control measures are appropriate (e.g., correct grounding and routing of control and main circuit wires).

Î Take the countermeasure to noises. Î Insert a surge absorber into a noise source such as an activation coil o

MC or electro-magnetic solenoids.

(6) Invalid motor parameters

set.

Check the motor parameters (P codes).

Î Correct the motor parameters by replacing with printed ones on the moto

nameplate

[ 2 ]

n Overvoltage

Problem The DC link bus voltage was over the detection level of overvoltage.

OU1

Overvoltage occurs during the acceleration. OU2 Overvoltage occurs during the deceleration. OU3 Overvoltage occurs during running at constant speed.

Possible Causes What to Check and Suggested Measures

(1) The power supply voltage

was over the range of the inverter’s specifications.

(2) A surge current entered

the input power source.

Measure the input voltage.

Î Decrease the voltage to within that of the specifications.

If within the same power source a phase-advancing capacitor is turned ON or OFF or a thyristor converter is activated, a surge (temporary precipitous rise in voltage or current) may be caused in the input power.

Î Install a DC reactor.

(3) The deceleration time was

too short compared with the inertia of the load.

(4) Braking load was too

heavy.

Calculate the deceleration time from the inertia of the load and the braking torque again.

Î Increase the deceleration time.

Compare the braking torque of the load with that of the inverter.

Î Select a minimum resistance braking resistor connectable to the inverter. Î Change the inverter for an upper size.

(5) A high intensity noise was

given to the inverter.

Check if noise control measures are appropriate (e.g., correct grounding and routing of control and main circuit wires).

Î Take the countermeasure to noises. Î Insert a surge absorber into a noise source such as an activation coil o

MC or electro-magnetic solenoids.

(6) No connected braking

resistor

Check whether the braking resistor is connected to the inverter correctly.

Î Check the braking resistor is connected to terminals P (+) and DB

correctly. Or, retighten screws/nuts.

Î Check whether any terminal bites the wire sheath. If so correct it.

[ 3 ]

Undervoltage

Problem DC link bus voltage was below the undervoltage detection level.

Possible Causes What to Check and Suggested Measures

(1) A momentary power failure

occurred.

Î Reset the alarm.

7.3.1 Judgment on service life

(1) Viewing data necessary for judging service life; Measurement procedures

Through Menu 5 "Maintenance Information" in Programming mode, you can view on the optional multi-function keypad (option) various data (as a guideline) necessary for judging whether key components such as the DC link bus capacitor, the electrolytic capacitor on the printed circuit board, and the cooling fan are approaching their service life.

-1 Measuring the capacitance of the DC link bus capacitor (in comparison with that at factory shipment)

Measure the capacitance of the DC link bus capacitor according to the procedure given below. The result will be displayed on the keypad as a ratio (%) to the initial capacitance at the time of factory shipment.

----------------------------------------------- Procedure for measuring capacitance -----------------------------------------------

1) To ensure validity in the comparative measurement, configure the condition of the inverter as follows.

• Remove the option card (if already in use) from the inverter.

• In case another inverter is connected via the DC link bus to the P(+) and N(-) terminals of the main circuit,

disconnect the wires. (You do not need to disconnect a DC reactor (optional), if any.)

• Disconnect power wires for the auxiliary input to the control circuit (R0, T0).

• If the multi-function keypad is mounted, remove it.

• Turn OFF all the digital input signals fed to terminals [FWD], [REV], [EN], and [X1] through [X8] of the

control circuit.

• If the encoder is wired at terminals (P0, PA, PB, and PZ (if any)), remove it..

• If an external apparatus is attached to terminal [PLC], disconnect it.

• Ensure that transistor output signals ([Y1] ─ [Y4]) and relay output signals ([Y5A/C] and [30A/B/C]) will not

be turned ON.

If negative logic is specified for the transistor output and relay output signals, they are considered ON when the inverter is not running. Specify positive logic for them.

• Keep the ambient temperature within 25 ±10°C.

2) Switch ON the main circuit power.

3) Confirm that the cooling fan is rotating and the inverter is in stopped state.

4) Switch OFF the main circuit power.

5) Mount the multi-function keypad after five minutes having elapsed, switch ON the main circuit power again.

6) Select Menu 5 "Maintenance Information" in Programming mode and note the reading (relative capacitance (%) of the DC link bus capacitor).

-2 Measuring the capacitance of the DC link bus capacitor (during power-off time under ordinary operating condition)

In general, the discharging condition of the DC link bus capacitor during a power-off time under the ordinary operating condition at the end user’s installation is different from that under which the initial measurement is conducted at the time of factory shipment. As a result, the measured data for the DC link bus capacitor may not be updated. A method is provided, therefore, that allows you to measure the capacitance of the DC link bus capacitor during an ordinary power-off time by taking on (assuming) its discharging condition during a power-off time under the ordinary operation condition at the end user's installation.

Presented below is the procedure for taking on the discharging condition during a power-off time under the ordinary operating condition at the end user’s installation.

--------------------------------------- Procedure for setting up measurement condition ---------------------------------------

1) Set function code H98 (Maintenance function) to enable the user to specify the judgment criteria for the service life of the DC link bus capacitor (Bit 3) (refer to function code H98).

2) Place the inverter in stopped state.

3) Place the inverter in the state of power-off under ordinary operating conditions.

4) Set both function codes H42 (Capacitance of DC Link Bus Capacitor) and H47 (Initial Capacitance of DC Link Bus Capacitor) to "0000."

5) Switch OFF the inverter.

Measure the discharging time of the DC link bus capacitor and save the result in function code H47 (Initial Capacitance of DC Link Bus Capacitor).

The condition under which the measurement has been conducted will be automatically collected and saved.

During the measurement, " . . . . " will appear on the LED monitor.

6) Switch ON the inverter again. Confirm that H42 (Capacitance of DC Link Bus Capacitor) and H47 (Initial Capacitance of DC Link Bus Capacitor) hold right values. Move to Menu 5 "Maintenance Information" and confirm that the relative capacitance (ratio to full capacitance) is 100%.

If the measurement has failed, "0001" is entered into both H42 and H47. Check whether there has been any mistake in operation and conduct the measurement again.

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

To change the settings back to the state at the time of factory shipment, set H47 (Initial Capacitance of DC Link Bus Capacitor) to "0002"; the original values will be restored.

Hereafter, each time the inverter is switched OFF, the discharging time of the DC link bus capacitor is automatically measured if the above condition is met.

The condition given above produces a rather large measurement error. If this mode gives you a lifetime alarm, set H98 (Protection/Maintenance Function) back to the factory defaults (Bit 3 (Select life

udgment criteria of DC link bus capacitor) = 0) and conduct the measurement under the condition at the

time of factory shipment.

Electrolytic capacitor on the printed circuit board

Move to Menu 5 "Maintenance Information" in Programming mode and check the accumulated run time of the electrolytic capacitor on the printed circuit board. This value is calculated from the cumulative total number of hours a voltage has been applied on the electrolytic capacitor, adjusted with ambient temperature, and is used as the basis for judging whether it has reached its service life. The value is displayed on the LED monitor in units of 1 hour.

Cooling fan

Select Menu 5 "Maintenance Information" and check the accumulated run time of the cooling fan. The inverter accumulates hours for which the cooling fan has run. The display is in units of 1 hour. The accumulated time should be used just a guide since the actual service life will be significantly affected by the temperature and operation environment.

7-4

(2) Early warning of lifetime alarm

For the components listed in Table 7.3, you can get an early warning of lifetime alarm at one of the transistor output terminals ([Y1] to [Y4]) and the relay contact terminals ([Y5A] - [Y5C], and [30A/B/C]) as soon as any of the conditions listed under the "Judgment level" column has been exceeded.

*1 (estimated service life at the inverter’s ambient temperature of 40℃in 80％ of the rated RMS current)

7.4 Measurement of Electrical Amounts in Main Circuit

Because the voltage and current of the power supply (input, primary circuit) of the main circuit of the inverter and those of the motor (output, secondary circuit) include harmonic components, the readings may vary with the type of the meter. Use meters indicated in Table 7.4 when measuring with meters for commercial frequencies.

The power factor cannot be measured by a commercially available power-factor meter that measures the phase difference between the voltage and current. To obtain the power factor, measure the power, voltage and current on each of the input and output sides and calculate in the following formula.

7.5 Insulation Test

Because an insulation test is made in the factory before shipment, avoid a Megger test.

If a Megger test is unavoidable, follow the procedure below. Because a wrong test procedure will cause breakage of the inverter, take sufficient care.

A dielectric strength test will cause breakage of the inverter similarly to the Megger test if the test procedure is wrong. When the dielectric strength test is necessary, contact your Fuji Electric representative.

(1) Megger test of main circuit

1) Use a 500 VDC Megger and shut off the main power supply without fail during measurement.

2) If the test voltage leaks to the control circuit due to the wiring, disconnect all the control wiring.

3) Connect the main circuit terminals with a common cable as shown in Figure 7.2.

4) The Megger test must be limited to across the common line of the main circuit and the ground terminal (

5) 5 MΩ (1 MΩ for the EMC filter built-in type of inverters) or a larger value displayed at the Megger indicates a correct state. (The value is for a discrete inverter.)

Figure 7.2 Megger Test

(2) Dielectric strength test of control circuit

Do not perform a Megger test or dielectric strength test for the control circuit. Prepare a high resistance range tester for the control circuit.

1) Disconnect all the external wiring from the control circuit terminals.

2) Perform a continuity test to the ground. 1 MΩ or a larger measurement indicates a correct state.

(3) Dielectric strength test of external main circuit and sequence control circuit

Disconnect all the inverter terminals so that the test voltage is not applied.

(Note 1) When connecting a DC reactor (DCR), first remove the short bar between terminals P1 and P(+).

(Note 2) To protect wiring, insert a molded case circuit breaker (MCCB) or an earth leakage circuit breaker (ELCB) (with

overcurrent protection) of the type recommended for the inverter between the commercial power supply and the inverter. Do not use a circuit breaker with a capacity exceeding the recommended capacity.

(Note 3) Connect this pair of wires to terminals [R0] and [T0] if you want the inverter to stay in standby state, with only its control

circuit being active, when the main circuit power supply is open (cut off). Without this pair of wires connected to these terminals, you can still run the inverter as long as the main wires of the commercial power supply to the main circuit are properly connected. Connect terminal [R0] and [T0] with the output side on earth leakage circuit breaker when you connect earth leakage circuit breaker. When you connect terminal [R0] and [T0] with the input side of on earth leakage circuit breaker, an earth leakage circuit breaker malfunctions. Connect insulation transformer or supplementary point of contact B with the position shown in the figure below whenever you connect [R0] and [T0] with the input side of an earth leakage circuit breaker.

(Note 4) For the wiring of the control circuit, use shielded or twisted wires. When using shielded wires, connect the shields to earth.

To prevent malfunction due to noise, keep the control circuit wires as far away as possible from the main circuit wires (recommended distance: 10 cm or longer), and never put them in the same wire duct. Where a control circuit wire needs to cross a main circuit wire, route them so that they meet at right angles.

(Note 5) Common terminals [11], [CM] and [CMY] for the control input/output circuits are insulated each other.

(Note 6) Use a shielded sheath cable to wire the control signals. Process and terminate correctly the shielded sheath ends

according to wiring state and specifications of the pulse encoder or host equipment. The figure in this section illustrates an example for the cable’s shielded sheath grounding where the shielded sheath end is connected to the grounding wire of the motor and another end is opened at the inverter side. If the inverter malfunctions due to noises ｐｉｃｋｅｄ up by the signal cable, connecting the inverter end of the shielded sheath to the inverter’s [CM] terminal may reduce the noise affection. When the wiring between the encoder and the inverter is long, the allophone and the torque ripple might be generated because the signal from the encoder malfunctions by interfering with A phase and B phase. In this case, please execute measures such as; wiring shorter cable, cable of smaller electrostatic capacity, etc.

(Note 7) A CAN port is provided on the FRNLM1S-C, -E, -A and -J, not on the FRNLM1S-EA, -AA or -JA.

(Note 8) Please connect it according to the drawing when you wire for the braking resistance. There is a possibility that charge

resistance and an inverter internal parts are damaged when miss wiring.

• Please connect it according to the drawing when you wire for the braking resistance.

Fire or accident could occur.

Grounding fault protection

Overvoltage protection

Undervoltage protection

Input phase loss protection

Overheating protection

External alarm input

The inverter is stopped for protection against overcurrent caused by an overload.

The inverter is stopped for protection against overcurrent caused by a short circuit in the output circuit.

The inverter is stopped for protection against overcurrent caused by a grounding fault in the output circuit. If the power supply is turned on with the grounding fault, the protection may be invalidated.

An excessive voltage (400 VDC for the 200 V class series, 800 VDC for the 400 V class series) in the DC link circuit is detected and the inverter is stopped. If a remarkably large voltage is applied by mistake, the protection cannot be made.

Stops the inverter output when the DC link bus voltage drops below the undervoltage level (200 VDC for the 200 V class series, 400 VDC for the 400 V class series).

When the inverter is driven by a battery power, however, it disables an undervoltage alarm detection and is to output no alarm signal.

Detects input phase loss, stopping the inverter output. This function prevents the inverter from undergoing heavy stress that may be caused by input phase loss or inter-phase voltage unbalance and may damage the inverter.

If connected load is light or a DC reactor is connected to the inverter, this function will not detect input phase loss if any.

The temperature of the heat sink in the event of cooling fan trouble and overload is detected to stop the inverter.

The temperature inside the inverter unit in the event of cooling fan trouble and overload is detected to stop the inverter.

With the digital input signal THR, the inverter is stopped as for an alarm.

*1 When the inverter is equipped with the multi-function keypad, it displays the alarm letters on the LED indicator of the

keypad.

*2 This alarm [30A/B/C] may not be output depending upon the data setting of the function code.

Upon detection of an abnormal condition in the charger circuit inside the inverter, this function stops the inverter output. (Applicable to 37 kW or above (3-phase 400 V))

The temperature inside the IGBT is calculated from the detection of output current and internal temperature, to shut off the inverter output.
