Instructions

Thank you for purchasing our FRENIC5000VG7S series inverter. This product is used to drive a 3-phase induction motor at variable speed. As incorrect use of this product may result in personal injury and/or property damage, read all operating instructions before using. As this manual does not cover the use of function cords and option cards, etc., refer to FRENIC5000VG7S Users Manual.

Safety Instructions

Read this manual carefully before installing, connecting (wiring), operating, servicing, or inspecting the inverter. Familiarize yourself with all safety features before using the inverter. In this manual, safety messages are classified as follows:

Improper operation may result in serious personal injury or death.

Improper operation may result in slight to medium personal injury or property damage.

Situations more serious than those covered by CAUTION will depend on prevailing circumstances. Always follow instructions.

Instructions on use

· This inverter is designed to drive a 3-phase induction motor and is not suitable for a single-phase motor or others, as fire may result.

· This inverter may not be used (as is) as a component of a life-support system or other medical device directly affecting the personal welfare of the user.

· This inverter is manufactured under strict quality control standards. However, safety equipment must be installed if the failure of this device may result in personal injury and/or property damage.

There is a risk of accident.

Instructions on installation

· Mount this inverter on an incombustible material such as metal.

There is a risk of fire.

· Do not place combustible or flammable material near this inverter, as fire may result.

· The inverter housed in IP00 (18.5kW or over) should be installed in a place where no one can touch it

easily.

Electric shock or injury may result.

0-2

· Do not hold or carry this inverter by the surface cover. Inverter may be dropped causing injury.

· Ensure that the inverter and heat sink surfaces are kept free from foreign matter (lint, paper dust, small

chips of wood or metal chips), as fire or accident may result.

· Do not install or operate a damaged inverter or an inverter with missing parts, as injury may result.

· When changing installation bracket position, use the attached screws, as injury may result.

Instructions on wiring

· Confirm that the phases and rated voltage of this product match those of the AC power supply, as injury may result.

· Do not connect the AC power supply to the output terminals (U, V, and W), as injury may result.

· Do not connect a braking resistor directly to the DC terminals (P(+) and N(-)), as fire may result.

· When using DC power input, ensure that the fan power switching connector (CN RXTX) is correctly

engaged in the inverter as a trouble may occur.

· When using DC power input of 18.5kW or larger inverter, be sure to connect AC power to terminals R0 and T0 for a power supply of fan as a trouble may occur.

· Ensure that the noise generated by the inverter, motor, or wiring does not adversely affect peripheral sensors and equipment, as accident may result.

0-3

Instructions on operation

· Be sure to install the surface cover before turning on the power (closed). Do not remove the cover while power to the inverter is turned on.

Electric shock may occur.

· Do not operate switches with wet hands, as electric shock may result.

· When the retry function is selected, the inverter may restart automatically after tripping. (Design the

machine to ensure personal safety in the event of restart)

Accident may result.

· When the torque limiting function is selected, operating conditions may differ from preset conditions (acceleration/deceleration time or speed). In this case, personal safety must be assured.

Accident may result.

· As the STOP key is effective only when a function setting has been established, install an emergency switch independently, and when an operation via the external signal terminal is selected, the STOP key on the KEYPAD panel will be disabled.

Accident may result.

· As operations start suddenly if alarm is reset with a running signal input, confirm that no running signal is input before resetting alarm.

Accident may result.

· When an alarm is activated, the motor coasts. If the motor needs to be stopped in such a case, install a brake to the machine with the motor.

Accident may result.

· If AUTO RESTART is selected in the restart mode after momentary power failure (function code F14), the inverter restarts automatically starting the motor rotation when the power is recovered.

Accident may result.

· When the tuning (function code H01) is started, the motor, machine or equipment starts and stops repeatedly. Ensure safety before performing tuning.

Accident may result.

· If the user set the function codes wrongly or without completely understanding this user’s manual, the motor may rotate with a torque or at a speed not permitted for the machine.

Accident or injury may result.

· Do not touch inverter terminals when energized even if inverter has stopped.

Electric shock may result.

· Do not start or stop the inverter using the main circuit power.

Failure may result.

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

Burns may result.

· As the inverter can set high speed operation easily, carefully check the performance of motor or machine before changing speed settings.

Injury may result.

· Do not use the inverter braking function for mechanical holding.

Injury may result.

· During pre-excitation, the speed adjuster does not function and the motor may be rotated by load disturbance. When using pre-excitation, therefore, also use the mechanical brake.

Injury may result.

· If improper data is set at the function code related with speed adjuster as in the case of setting high gain abruptly, the motor may hunt.

Injury may result.

0-4

Instructions on maintenance, inspection, and replacement

· Wait a minimum of five minutes (15kW or less) or ten minutes (18.5kW or more) after power has been turned off (open) before starting inspection. (Also confirm that the charge lamp is off and that DC voltage between terminals P(+) and N(-) does not exceed 25V.)

Electric shock may result.

· Only authorized personnel should perform maintenance, inspection, and replacement operations. (Take off metal jewelry, such as watches and rings. Use insulated tools.)

Electric shock or injury may result.

Instructions on disposal

· Treat as industrial waste when disposing it.

Injury may result.

Other instructions

· Never modify the product.

Electric shock or injury may result.

Compliance with European Standard

The CE marking presented on Fuji products is related to the Council Directive 89/336/EEC and the Low Voltage Directive 73/23/EEC for the Electromagnetic Compatibility (EMC) in Europe.

Compliant standards

････

EN 61800-3: 1997

････

EN 50178: 1997

Only the models in the 400V series comply with the standards above among the "FRENIC5000 VG7S" series. The 200V series do not conform to the standards. Please note that products of the CT/HT use 18.5 kW and the VT use 22 kW do not comply with the standards, and if you need to use compliant products, you should use the products of the CT/HT use 22 kW and the VT use 30 kW which are models with larger capacities by one grade.

1. Compliance with Low Voltage Directive 1-1 Overview

Inverters are subject to the Low Voltage Directive in Europe. Fuji has obtained an approval for the compliance from a European inspection organization, and voluntarily declares the compliance with the Low Voltage Directive.

1-2 Notes See the notes below when you use the inverters in your products compliant with the Low Voltage Directive in Europe.

・ The contact capacity for the alarm relay output (30A, B, C) and the relay signal output (Y5A, Y5C) is DC

48V, 0.5A.

・ Connect your inverter to the ground securely. ・ Connect a ring terminal to a wire when you attach it to the main circuit and inverter ground terminals. ・ Use an independent wiring for the inverter ground terminal G. (Do not connect two or more wires) ・ When you use an earth leakage breaker (RCD), you can use only the Type B for protection for the power

supply. Also you should use a transformer for double insulation or reinforced insulation to insulate your inverter from the power supply.

・ Use a molded case circuit breaker (MCCB) and a magnetic contactor (MC) compliant with the EN or IEC

standard.

・ For a power supply system (I-T NET) where a neutral point is not grounded, the control terminals are

provided as basic insulation in respect to the main circuit. When a person may touch them directly, you should add an external insulation circuit for double insulation.

・ Use your inverter under a condition corresponding to the overvoltage category III and the pollution degree 2

or more prescribed in the IEC664. Install your inverter in a control panel (IP54 or more) with a structure preventing water, oil, carbon and dusts from entering for meeting the pollution degree 2 or more.

・ Use a wire with the diameter and the type prescribed in the Appendix C of the EN 60204 for the

input/output wiring for your inverter.

・ When you install an external heatsink which is a heatsink for inverter external to the control panel, you

should install a protection cover preventing a capacitor and a breaking resistor installed on the heatsink from being touched.

・ When you install an optional AC reactor, a DC reactor, and an external braking resistor, follow the

description below to prevent an electric shock due to touching the terminals and active electrical parts.

1) Install them in a casing or wall of the IP4X when a person may have an easy access to them.

2) Install them in a casing or wall of the IP2X when a person does not have an easy access to them.

(2) Pack the product with a plastic sheet or such if stored under undesirable conditions. (3) Seal in a desiccative such as silica gel when packing the product if it may be affected by moisture.

The requirements to be satisfied when storing the product for an extended period after purchased greatly depend on the environment. General requirements are listed below. (1) Satisfy the requirements for temporary storage.

If the storage period exceeds three months, the ambient temperature should be kept below 30 °C to protect the dead electrolytic capacitor from deterioration.

(2) Carefully pack the product to prevent the intrusion of moisture, etc. Seal in a desiccant to keep the relative

humidity inside the pack below 70%, as a guide.

(3) The product will be often exposed to moisture or dust if left mounted on a unit or console, especially in a

building under construction. In such a case, remove the product and relocate in a well-conditioned place. The electrolytic capacitor will be deteriorated if left dead for an extended period. Do not leave it dead for a period exceeding a year.

2-2 Installation Procedure

(1) Install the product onto a rigid structure in the vertical direction with the letters, FRENIC5000 VG7S, seen

from the front and fix with specified bolts. Do not install upside down or in the horizontal direction.

Failure to do so may lead to injury.

(2) The inverter generates heat during operation.

Reserve a space as shown in Figure 2-2-1 to ensure a sufficient flow of cooling air. The heat is radiated from the top. Do not install the inverter under any unit susceptible to heat.

(3) The cooling fins (heat sink) are heated to almost 90°C during operation of the inverter. The inverter

mounting surface should be made of a material capable of withstanding this temperature rise.

The fins may burn your skin.

· Install the inverter onto an incombustible material such as metal.

Failure to do so may lead to fire.

(4) When storing the inverter in a control panel, for example,

sufficiently ventilate the inverter so that its ambient temperature will not exceed the specified limit. Do not store the inverter in a small closed box that does not radiate heat well.

(5) When storing two or more inverters in a unit or control

panel, they are desirably arranged side by side to minimize the thermal effect on each other. If they are inevitably arranged with one above another, separating plate should be provided to prevent the heat transfer from the bottom side inverter to the above.

(6) The inverter is prepared to be mounted in a control

panel when delivered. It may be externally cooled using the optional adapter if 15kW or lower or with the mounting legs relocated if 18.5kW or higher. With the inverter externally cooled, the heat generated inside the unit or control panel is dissipated because the cooling fins, which radiate 70% of the generated heat, are excluded from the unit or control panel. Do not exclude the cooling fins where they may be clogged with lint or damp dust.

· Do not admit lint, paper, wooden chips, dust, metallic pieces, and any other foreign matters into the inverter or allow them to stick to the cooling fins.

Doing so may lead to fire or accident.

2-3 Electric Connections

Removing the surface cover exposes the terminal blocks. Correctly wire them after reading the following instructions.

2-3-1 Basic Connections

(1) Connect power supply leads to the main circuit power terminals, L1/R, L2/S, and L3/T. Connecting any

power supply lead to another terminal may fail the inverter. Check that the supply voltage does not exceed the permissible limit indicated on the nameplate, etc.

(2) The grounding terminal must be grounded to prevent disasters such as electric shock and fire and reduce

the noise. (3) Use a reliable crimp terminal to connect each lead. (4) After making connections (wiring), check that:

1) leads are correctly connected,

2) all necessary connections are made, and

3) no terminal or wire is short-circuited or grounded.

(5) When any connection is changed after the inverter is energized:

It takes a long time for the smoothing capacitor in the DC link circuit of the main circuit to be discharged after

the power supply is shut off. After the CHARGE lamp goes off, check with a multimeter or such that the DC

voltage has been reduced to a safe level (25V DC or less). Short-circuiting a circuit in which a voltage

(potential) still remains may generate sparks. Wait until the voltage goes away.

· Always connect the grounding lead.

Failure to do so may lead to electric shock or fire.

· The wiring work should be performed by qualified persons.

· Before working, check that the power supply is shut off (open).

Failure to do so may lead to electric shock.

· Do not use any lead size other than specified.

Doing so may lead to fire.

2-3-2 Wiring of Main Circuit and Grounding Terminals

Table 2-3-1 Functions of Main Circuit and Grounding Terminals

Terminal symbol Terminal name Description L1/R, L2/S, L3/T Main circuit power input terminals Connected with three-phase power source.

U, V, W Inverter output terminals Connected with three-phase motor.

R0, T0 Auxiliary control power input terminals Connected with the same AC power source

as used for main circuit, as back-up power source for control circuit.

P1, P(+) DC reactor connecting terminals Connected with (optional) input power-factor

P(+), DB Braking resistor connecting terminals Connected with (optional) braking resistor.

P(+), N(-)

DC link circuit terminals Supplies DC link circuit voltage.

Connected with (optional) external braking unit or (optional) power regenerative unit.

Inverter grounding terminals Grounds inverter chassis (casing).

Connected with earth.

(1) Main circuit power input terminals (L1/R, L2/S, and L3/T)

1) The main circuit power input terminals, L1/R, L2/S, and L3/T should be connected with the power source via earth-leakage circuit breaker for line protection. Any phase may be connected to any lead. If the zero-phase current is detectable by the upstream system, however, ordinary circuit breakers may be used.

2) Connect a magnetic contactor so that the inverter can be disconnected from the power source to minimize the influence of any failure when the inverter protective function is activated.

3) Do not start or stop the inverter by turning the main power switch on or off. Use the control circuit terminals, FWD and REV, or the FWD, REV, and STOP keys on the KEYPAD panel to start or stop the inverter. When the inverter is inevitably started or stopped using the main power switch, do not turn it on or off more than once per hour.

4) Do not connect any terminal to a single-phase power source.

2-7

(2) Inverter output terminals (U, V, and W)

1) Connect three-phase motor leads to the inverter output terminals, U, V, and W with care not to connect a wrong phase.

2) Do not connect a phase advancing capacitor or surge absorber (suppressor) to the inverter output terminals.

3) If the wiring between the inverter and the motor is too long, a high-frequency current will run through the wiring due to floating capacity to trip the inverter because of overcurrent, increase the leakage current, and/or deteriorate the current indication accuracy. Therefore, the motor wiring length should not exceed 50m for 3.7kW or lower inverters or 100m for others, as a guide. Connect the optional output circuit filter (OFL filter) if the wiring is too long.

4) When you use a motor with an encoder, limit the wiring distance between your inverter and motor to 100 m or less. This limit is due to encoder characteristic. When the distance exceeds 100 m, you need an arrangement such as inserting an isolation converter.

Without output circuit filter

When two or more motors are to be driven, the total length of wirings to those motors should not exceed 50m for 3.7kW or lower inverters or 100m for 5.5kW or higher ones.

With output circuit filter

When two or more motors are to be driven, the total length of wirings to those motors should not exceed 400m.

Note: When a thermal relay is used between the inverter and the motor, especially for 400V series, the

thermal relay may malfunction even with a wiring length less than 50m. In this case, connect an OFL filter or reduce the inverter operation noise (carrier frequency) using function code F26 (motor sound (carrier frequency)).

· Driving a 400V motor with an inverter If a motor is driven with a PWM inverter, the surge voltage generated by switching inverter elements is overlapped as applied to the motor terminals. Especially for 400V motors, the motor insulation may be deteriorated by the surge voltage if the motor wiring is too long. Therefore, any of the following measures should be taken when a 400V motor is to be driven with an inverter.

1) Use a motor with reinforced insulation (all the Fuji Electric's general-purpose motors have reinforced

insulation).

2) Connect the optional output circuit filter (OFL filter) to the inverter output terminals.

3) Shorten the wiring between the inverter and the motor as short as possible (to10 to 20m or less).

2-8

Figure 2-3-4

(3) Auxiliary control power input terminals (R0 and T0)

If the magnetic contactor in the power supply circuit to the inverter is turned off (open) when the protection circuit is activated, the inverter control power supply is shut off. As a result, alarm outputs (30A, B, and C) are no longer retained and indications on the KEYPAD panel go away. To prevent this, the same AC voltage as used for the main circuit is applied to the auxiliary control power input terminals, R0 and T0. Although the inverter functions with no voltage applied to these terminals, it is strongly recommended to connect the voltage to R0 and T0 to ensure safe operation.

1) When a radio noise filter is used, the power to be connected to the auxiliary control power input terminals, R0 and T0, should be taken from a point downstream the filter. If it is taken from a point upstream the filter, the noise reduction effect is impaired.

(4) DC reactor connecting terminals (P1 and P(+))

1) These terminals are provided to connect the optional input power-factor correcting DC reactor. A jumper is connected between the terminals before delivery from the factory. Remove the

jumper before connecting the DC reactor.

2) Do not remove the jumper when the DC reactor is not used.

Note: The DC reactors are (externally) provided as

standard equipment for 75kW or higher inverters. Always use the DC reactor for those inverters.

3) Connect a DC reactor for an inverter meeting the following conditions and having a rated motor output of 55 kW or less.

･ The capacity ratio between the power transformer

and the inverter follows the Figure 2-3-4.

･ You connect a thyristor load to the same power

supply, or you control to turn ON/OFF a capacitor adjusting power factor.

･ Imbalance of 2% or more exists in power supply.

(5) Braking resistor connecting terminals (P(+) and DB)

The optional braking resistor may be externally mounted. It is required when the inverter is operated frequently or under heavy inertia.

1) Connect the braking resistor terminals, P(+) and DB, to the inverter terminals, P(+) and DB.

2) Lay out so that the wiring length will not exceed 5m. The two leads should be twisted or in close contact (parallel).

· Do not directly connect the braking resistor to the DC terminals, P(+) and N(-).

Doing so may lead to fire.

(6) DC link circuit terminals (P(+) and N(-))

The 200V series, 75kW or higher and 400V series, 132kW or higher inverters contain no braking resistor drive circuit. When the braking resistor is required, a braking unit should be used.

1) Connect the braking unit terminals, P(+) and N(-), to the inverter terminals, P(+) and N(-). Lay out so that the wiring length will not exceed 5m. The two leads should be twisted or in close contact (parallel).

2) Connect the braking resistor terminals, P(+) and DB, to the braking unit terminals, P(+) and DB. Lay out so that the wiring length will not exceed 10m. The two leads should be twisted or in close contact (parallel). When the inverter terminals, P(+) and N(-), are not used, they should be left open. Never short these terminals or directly connect the braking resistor. Doing so may break the inverter.

3) Auxiliary contacts 1 and 2 of the braking unit have polarity. When connecting a PWM Converter, see the instruction manual for the unit.

(7) Inverter grounding terminals (

zG)

The inverter grounding terminals,

zG, must be grounded to ensure your safety and for noise measures.

The Technical Standards for Electric Equipment requires metallic frames of electric equipment be grounded to prevent disasters such as electric shock and fire. Connect the terminals as described below.

1) Connect to type D grounded poles for 200V series or type C grounded poles for 400V series according to the Technical Standards for Electric Equipment.

2) Connect the earth terminal to the dedicated grounding pole of the inverter system using a thick, short lead.

(8) Auxiliary power switching connector (CN UX) (18.5kW or higher)

For 18.5kW or higher inverters, if the supply voltage to the main circuit is within the range shown in Table 2-3-3, reconnect the auxiliary power switching connector, CN UX, to U2

. For other inverters, leave

the connector connected to U1

. For details, see Figure 2-3-9.

· Check that the number of phases and rated voltage of the product agree with those of the AC power source.

· Do not connect any AC power source to the output terminals, U, V, and W.

Doing so may lead to injury.

(9) Fan power switching connector (CN RXTX) (18.5kW or higher)

The VG7S accepts DC power inputs through a common DC terminal without using any optional equipment when combined with a PWM converter as shown in Figure 2-3-8. However, 18.5kW or higher inverters contain AC power operated parts such as AC cooling fan. When such DC power inputs are used, reconnect the fan power switching connector, CN RXTX, inside the inverter to R0-T0

as shown in Figure 2-3-6 and apply an AC power to the terminals, R0 and T0.

For details, see Figure 2-3-9.

Note: The fan power switching connector, CN RXTX, is normally connected to L1/R-L3/T. Do not reconnect the

connector when no DC power inputs are used. Always connect the same AC voltage as used for the main circuit to the auxiliary control power input terminals, R0 and T0. Failure to do so deactivates the fan, which may overheat (OH1) and then fail the inverter.

· Do not connect the fan power switching connector, CN RXTX, inside the inverter to a wrong terminal.

Doing so may fail the inverter.

· When DC power inputs are used, apply an AC power to R0 and T0 to drive the fan.

Failure to do so may fail the inverter.

Figure 2-3-8 An Example of Wiring of Inverter Combined with PWM Converter

Note 1: When a 15kW or lower inverter is combined with a PWM converter, do not directly connect any power

source to the auxiliary control power input terminals, R0 and T0. If connected to these terminals, the power source should be insulated from the main power supply to the PWM converter with insulating transformer. Examples of wiring of the PWM converter are given in the instruction manual for PWM converter.
