SAFETY INSTRUCTIONS

1. Electric Shock Prevention

WARNING

While power is on or when the inverter is running, do not open the front cover. You may get an electric shock.

Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.

If power is off, do not remove the front cover except for wiring or periodic inspection. You may access the charged inverter circuits and get an electric shock.

Before starting wiring or inspection, switch power off, wait for more than 10 minutes, and check for residual voltage with a meter (refer to chapter 2 for further details) etc.

Earth the inverter.

Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.

Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured.

Operate the switches and potentiometers with dry hands to prevent an electric shock.

Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise, you may get an electric shock.

Do not change the cooling fan while power is on. It is dangerous to change the cooling fan while power is on.

2. Fire Prevention

CAUTION

Mount the inverter and brake resistor on an incombustible surface. Installing the inverter directly on or near a combustible surface could lead to a fire.

If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire.

When a brake resistor is used, use an alarm signal to switch power off. Otherwise, the brake resistor will overheat abnormally due a brake transistor or other fault, resulting in a fire.

Do not connect a resistor directly to the DC terminals P(+), N(−). This could cause a fire.

A - 2

3. Injury Prevention

CAUTION

Apply only the voltage specified in the instruction manual to each terminal to prevent damage etc.

Ensure that the cables are connected to the correct terminals. Otherwise, damage etc. may occur.

Always make sure that polarity is correct to prevent damage etc.

While power is on and for some time after power-off, do not touch the inverter or brake resistor as they are hot and you may get burnt.

4. Additional instructions

Also note the following points to prevent an accidental failure, injury, electric shock, etc.

(1)

(2)

Wiring

CAUTION

Do not fit capacitive equipment such as a power factor correction capacitor, radio noise filter or surge suppressor to the output of the inverter.

The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.

(3)

Trial run

CAUTION

Check all parameters, and ensure that the machine will not be damaged by a sudden start-up.

(4)

Operation

WARNING

When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.

The [STOP] key is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately.

Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.

The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may damage the equipment.

Do not modify the equipment.

CAUTION

The electronic overcurrent protection does not guarantee protection of the motor from overheating.

Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected.

Take measures to suppress harmonics. Otherwise power harmonics from the inverter may heat/damage the power capacitor and generator.

A - 4

CAUTION

When a 400V class motor is inverter-driven, it should be insulation-enhanced or surge voltages suppressed. Surge voltages attributale to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

When parameter clear or all clear is performed, each parameter returns to the factory setting. Re-set the required parameters before starting operation.

The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and machine.

In addition to the inverter's holding function, install a holding device to ensure safety.

Before running an inverter which had been stored for a long period, always perform inspection and test operation.

(5)

Emergency stop

CAUTION

Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

(6)

Maintenance, inspection and parts replacement

CAUTION

Do not carry out a megger (insulation resistance) test on the control circuit of the inverter.

(7)

Disposing of the inverter

CAUTION

Treat as industrial waste.

(8) General

Many of the diagrams and drawings in this instruction manual show the inverter without a cover, or partially open. Never operate the inverter like this. Always replace the cover and follow this instruction manual when operating the inverter.

OUTLINE

1.2 Basic Configuration

1.2.1 Basic configuration

The following devices are required to operate the inverter. Proper peripheral devices must be selected and correct connections made to ensure proper operation. Incorrect system configuration and connections can cause the inverter to operate improperly, its life to be reduced considerably, and in the worst case, the inverter to be damaged. Please handle the inverter properly in accordance with the information in each section as well as the precautions and instructions of this manual. (For connections of the peripheral devices, refer to the corresponding manuals.)

Name Description

Use the power supply within the permissible power supply specifications of the inverter. (Refer to page 191.)

The breaker should be selected with care since a large inrush current flows in the inverter at power on. (Refer to page 41.)

Do not use this magnetic contactor to start or stop the inverter. It might reduce the inverter life. (Refer to page 41.)

The reactors must be used when the power factor is to be improved or the inverter is installed near a large power supply system (1000KVA or more and wiring distance within 10m (32.81 feet)). Make selection carefully.

•

The inverter life is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (Refer to page 12.)

•

Wrong wiring might lead to inverter damage. The control signal lines should be kept away from the main circuit to protect them from noise. (Refer to page

14.)

Do not connect a power capacitor, surge suppressor or radio noise filter to the output side.

To prevent an electric shock, always ground the motor and inverter. The ground wiring from the power line of the inverter as an induction noise reduction technique is recommended to be run by returning it to the ground terminal of the inverter. (Refer to page

38.)

2.1 Installation

2.1.1 Instructions for installation

For the FR-E520-0.1K to 0.75K-NA and FR-E510W-0.1K to 0.4K-NA, install the

inverter with the accessory cover or control panel (FR-PA02-

) front cover open.

<For the accessory cover> <For the control panel (FR-PA02

-02

1) Handle the unit carefully. The inverter uses plastic parts. Handle it gently to protect it from damage. Also, hold the unit with even strength and do not apply too much strength to the front cover alone.

2) Install the inverter in a place where it is not affected by vibration easily (5.9m/s maximum). Note the vibration of a cart, press, etc.

3) Note on ambient temperature. The inverter life is under great influence of ambient temperature. In the place of installation, the ambient temperature must be within the permissible range -10°C to +50°C (14°F to 122°F). Check that the ambient temperature is within that range in the positions shown in figure 3).

4) Install the inverter on a non-combustible surface. The inverter will be very hot (maximum about 150°C (302°F)). Install it on a noncombustible surface (e.g. metal). Also leave sufficient clearances around the inverter.

5) Avoid high temperatures and high humidity. Avoid direct sunlight and places of high temperature and high humidity.

6) Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust, dirt etc. Install the inverter in a clean place or inside a "totally enclosed" panel which does not accept any suspended matter.

7) Note the cooling method when the inverter is installed in an enclosure. When two or more inverters are installed or a ventilation fan is mounted in an enclosure, the inverters and ventilation fan must be installed in proper positions with extreme care taken to keep the ambient temperatures of the inverters with the permissible values. If they are installed in improper positions, the ambient temperatures of the inverters will rise and ventilation effect will be reduced.

8) Install the inverter securely in the vertical direction with screws or bolts.

2.2.2 Wiring of the main circuit

(1)

Wiring instructions

1) It is recommended to use insulation-sleeved solderless terminals for power supply and motor wiring.

2) Power must not be applied to the output terminals (U, V, W) of the inverter. Otherwise the inverter will be damaged.

3) After wiring, wire off-cuts must not be left in the inverter. Wire off-cuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in a control box etc., be careful so that chips and others do not enter the inverter.

4) Use thick cables to make the voltage drop 2% or less. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease, especially at the output of a low frequency. (A selection example for the wiring length of 20m (65.62 feet) is shown on page 21.)

5) For long distance wiring, the overcurrent protection may be activated improperly or the devices connected to the output side may misoperate or become faulty under the influence of a charging current due to the stray capacitance of the wiring. Therefore, the maximum overall wiring length should be as indicated in the following table. If the wiring length exceeds the value, it is recommended to set "1" in Pr. 156 to make the fast-response current limit function invalid. (When two or more motors are connected to the inverter, the total wiring length should be within the indicated value.)

INSTALLATION AND WIRING

)

6) Connect only the recommended optional brake resistor between the terminals P-PR (+ - PR). Keep terminals P-PR (+ - PR) of 0.1K or 0.2K open. These terminals must not be shorted.

0.1K and 0.2K do not accept the brake resistor. Keep terminals P-PR (+ - PR) open. Also, never short these terminals.

7) Electromagnetic wave interference The input/output (main circuit) of the inverter includes harmonic components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional radio noise filter (for use in the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.

8) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF option) in the output side of the inverter. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are installed, immediately remove them. (When using the FR-BIF radio noise filter with a single-phase power supply, connect it to the input side of the inverter after isolating the T phase securely.)

9) W hen rewiring after operation, make sure that the POWER lamp has gone off, and when more than 10 minutes has elapsed after power-off, check with a meter etc. that the voltage is zero. After that, start rewiring work. For some time after power-off, there is a dangerous voltage in the capacitor.

2.2.3 Wiring of the control circuit

(1)

Wiring instructions

1) Terminals SD, SE and 5 are common to the I/O signals. These common terminals must not be earthed to the ground. Terminals SD and 5 are not isolated. (Those of the 400V class are isolated.)

2) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit).

3) The frequency input signals to the control circuit are micro currents. W hen contacts are required, use two or more parallel micro signal contacts or a twin contact to prevent a contact fault.

4) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.

5) W hen bar terminals and solid wires are used for wiring, their diameters should be

0.9mm (0.04 inches) maximum If they are larger, the screw threads may be damaged during tightening.

Wiring method

1) For wiring the control circuit, use cables after stripping their sheaths. Refer to the gauge printed on the inverter and strip the sheaths to the following dimensions. If the sheath is stripped too much, its cable may be shorted with the adjoining cable. If the sheath is stripped too little, the cable may come off.

7mm±1mm (0.28inches± 0.04inches

2) When using bar terminals and solid wires for wiring, their diameters should be

0.9mm maximum. If they are larger, the threads may be damaged during tightening.

3) Loosen the terminal screw and insert the cable into the terminal.

4) Tighten the screw to the specified torque. Undertightening can cause cable disconnection or misoperation. Overtightening can cause damage to the screw or unit, leading to short circuit or misoperation.

⋅

Tightening torque: 0.25 N

m to 0.49 N⋅m

* Use a size 0 screwdriver.

Note: When routing the stripped cables, twist them so that they do not become loose.

In addition, do not solder them.

(4) Control logic changing (400V class only)

For the 200V and 100V class inverters, the logic cannot be changed. The input signal logic is factory-set to the sink mode. To change the control logic, the position of the connector beside the control circuit terminal block must be changed.

INSTALLATION AND WIRING

1) Use tweezers etc. to remove the connector in the sink logic position and fit it in the source logic position. Do this position changing before switching power on.

Note:1. Make sure that the front cover has been installed securely.

2. The front cover has a capacity plate and the inverter a rating plate on it. Since these plates have the same serial numbers, always reinstall the removed cover to the inverter from where it was removed.

3. Always install the sink-source logic changing connector in either of the positions. If two connectors are installed in these positions at the same time, the inverter may be damaged.

2) Sink logic type

2.2.6 Design information

1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for commercial power supply-inverter switch-over. When there is a commercial power supply-inverter switch-over circuit as shown below, the inverter will be damaged by leakage current from the power supply due to arcs generated at the time of switch-over or chattering caused by a sequence error.

2) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter's primary circuit and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.

3) Since the input signals to the control circuit are on a low level, use two or more parallel micro signal contacts or a twin contact for contact inputs to prevent a contact fault.

4) Do not apply a large voltage to the contact input terminals (e.g. STF) of the control circuit.

5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp etc.

6) Make sure that the specifications and rating match the system requirements.

To improve the power factor, insert a power factor improving reactor in the inverter's input or DC circuit. For details, refer to the FR-A500/E500 series technical information

INSTALLATION AND WIRING

2.3.2 Inverter-generated noise and reduction techniques

Some noises enter the inverter causing it to incorrectly operate, and others are radiated by the inverter causing misoperation of peripheral devices. Though the inverter is designed to be insusceptible to noise, it handles low-level signals, so it requires the following basic measures to be taken. Also, since the inverter chops the output at high carrier frequencies, it could generate noise. If these noises cause peripheral devices to misoperate, measures should be taken to suppress noise. The measures differ slightly depending on noise propagation paths.

1) Basic measures

Do not run the power cables (I/O cables) and signal cables of the inverter in parallel with each other and do not bundle them.

Use twisted shield cables for the detector connecting and control signal cables and connect the sheathes of the shield cables to terminal SD.

Ground the inverter, motor, etc. at one point.

2) Measures against noise which enters and causes misoperation of the inverter When devices which generate noise (devices which use magnetic contactors, magnetic brakes, many relays, for example) are installed near the inverter, the inverter may misoperate due to noise. The following measures must be taken:

Provide surge suppressors for devices that generate noise to suppress noise.

Fit data line filters (refer to page 38) to signal cables.

Ground the shields of the detector connection and control signal cables with cable clamp metal.

INSTALLATION AND WIRING

)

3) Measures against noises which are radiated by the inverter causing misoperation of peripheral devices. Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuit (I/O), those electromagnetically and electrostatically inducted to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

Noise Path Measures

When devices which handle low-level signals and are susceptible to misoperation due to noise (such as instruments, receivers and sensors) are installed near the inverter and their signal cables are contained in the same panel as the inverter or are run near the inverter, the devices may be misoperated by air-propagated noise and the following measures must be taken: (1) Install easily affected devices as far away as possible from the

1), 2), 3)

4), 5), 6)

inverter.

(2) Run easily affected signal cables as far away as possible from the

inverter.

(3) Do not run the signal cables and power cables (inverter I/O cables) in

parallel with each other and do not bundle them.

(4) Insert line noise filters onto I/O and radio noise filters into inputs to

suppress cable-radiated noises.

(5) Use shielded cables for signal cables and power cables and run them

in individual metal conduits to further reduce effects. When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises may be propagated to the signal cables causing misoperation of the devices and the following measures must be taken: (1) Install easily affected devices as far away as possible from the

inverter. (2) Run easily affected signal cables as far away as possible from the

inverter. (3) Do not run the signal cables and power cables (inverter I/O cables) in

parallel with each other and do not bundle them. (4) Use shielded cables for signal cables and power cables and run them

in individual metal conduits to further reduce effects. When the power supplies of the peripheral devices are connected to the power supply of the inverter within the same line, inverter-generated noise may flow back through the power supply cables causing misoperation of the devices and the following measures must be taken: (1) Install the radio noise f ilter (F R-BIF ) t o t he power cables (input cables)

of the inverter. (2) Install the line noise filter (FR-BLF, FR-BSF01) to the power cables

(I/O cables) of the inverter. When a closed loop circuit is f ormed by connecting the peripheral device wiring to the inverter, leakage current may flow through the ground cable of the inverter causing misoperation of the device. In such a case, disconnection of the ground cable of the device may cause the device to operate properly.

2.3.3 Leakage currents and countermeasures

Due to the static capacitance existing in the inverter I/O wiring and motor, leakage currents flow through them. Since their values depend on the static capacitance, carrier frequency, etc., take the following measures.

(1)

To-ground leakage currents

Leakage currents may flow not only into the inverter's own line but also into the other lines through the ground cable, etc. These leakage currents may operate earth leakage circuit breakers and earth leakage relays unnecessarily.

""""

Countermeasures

If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of the inverter. Note that motor noise increases. Selection of Soft-PWM (Pr. 240) will make it unoffending.

By using earth leakage circuit breakers designed for harmonic and surge suppression (e.g. Mitsubishi's Progressive Super Series) in the inverter's own line and other line, operation can be performed with the carrier frequency kept high (with low noise).

""""

To-ground leakage current

Note that a long wiring length will increase leakage currents. Decrease the carrier frequency of the inverter to reduce leakage currents.

Higher motor capacity leads to larger leakage currents. The leakage currents of the 400V class are higher than those of the 200V class.

(2)

Line-to-line leakage currents

Harmonics of leakage currents flowing in static capacities between the inverter output cables may operate the external thermal relay unnecessarily. When the wiring length is long (50m (164.04 feet) or more) for the 400V class models, the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases.

To ensure that the motor is protected not to be influenced by line-to-line leakage currents, we recommend the protection method which uses a temperature sensor to directly detect motor temperature.

2.3.4 Inverter-driven 400V class motor

In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures:

" Measures

It is recommended to take either of the following measures:

(1) Rectifying the motor insulation

For the 400V class motor, use an insulation-rectified motor. Specifically,

1) Specify the "400V class inverter-driven, insulation-rectified motor".

2) For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven, dedicated motor".

(2) Suppressing the surge voltage on the inverter side

On the secondary side of the inverter, connect the optional surge voltage suppression filter (FR-ASF-H).

Install a no-fuse breaker (NFB) in the power supply side for protection of the inverter's primary wiring. Refer to the previous table and choose the NFB according to the inverter's power supply side power factor (which changes with the power supply voltage, output frequency and load). Especially for a completely electromagnetic type NFB, the one with a larger capacity must be selected since its operational characteristics change with harmonic currents. (Check the data of the corresponding breaker for confirmation.) Also, the earth leakage circuit breaker used should be durable against harmonic/surge (such as the Progressive Super Series).

When the inverter is connected near a largecapacity power supply transformer (500kVA or more, wiring length 10m (32.81 feet) maximum) or there is power capacitor switchover, excessive peak currents may flow into the power input circuit and damage the converter circuit. In such a case, the power supply improving reactor (FR-BEL or FRBAL) must be installed. When the FR-E510W-0.4K-NA is connected to a single-phase 100V class output power transformer (in excess of 50kVA capacity), install the power factor improving reactor (FR-BAL-2.2K) to improve reliability.

Note:1. The earth leakage circuit breaker should be installed to the primary (power

supply) side of the inverter.

2. Ground fault in the secondary side of the inverter can be detected at the running frequency of 120Hz or lower.

3. In the

connection neutral point grounded system, the sensitivity current becomes worse for ground faults in the inverter secondary side. Hence, the protective grounding of the load equipment should be 10Ω or less.

4. When the breaker is installed in the secondary side of the inverter, it may be unnecessarily operated by harmonics if the effective value is less than the rating. In this case, do not install the breaker since the eddy current and hysteresis loss increase and the temperature rises.

* Note the leakage current value of the noise filter installed on the inverter input

2.3.7 Instructions for compliance with the European standards

(The products conforming to the Low Voltage Directive carry the CE mark.)

(1)

EMC Directive

1) Our view of transistorized inverters for the EMC Directive

A transistorized inverter is a component designed for installation in a control box and for use with the other equipment to control the equipment/device. Therefore, we understand that the EMC Directive does not apply directly to transistorized inverters. For this reason, we do not place the CE mark on the transistorized inverters. (The CE mark is placed on inverters in accordance with the Low Voltage Directive.) The European power drive manufacturers' organization (CEMEP) also holds this point of view.

2) Compliance

We understand that the transistorized inverters are not covered directly by the EMC Directive. However, the EMC Directive applies to machines/equipment into which transistorized inverters have been incorporated, and these machines and equipment must carry the CE marks. Hence, we prepared the technical information "EMC Installation Guidelines" (information number BCN-A21041-

202) so that machines and equipment incorporating transistorized inverters may conform to the EMC Directive more easily.

3) Outline of installation method

Install an inverter using the following methods: * Use the inverter with an European Standard-compliant noise filter. * For wiring between the inverter and motor, use shielded cables or run them

in a metal piping and ground the cables on the inverter and motor sides with the shortest possible distance.

* Insert a line noise filter and ferrite core into the power and control lines as

required. Full information including the European Standard-compliant noise filter specifications are written in the technical information "EMC Installation Guidelines" (BCN-A21041-202). Please contact your sales representative.

Low Voltage Directive

1) Our view of transistorized inverters for the Low Voltage Directive

Transistorized inverters are covered by the Low Voltage Directive (Standard to comply with: DIN VDE0160 (200V class), EN50178 (400V class, 100V class)).

2) Compliance

We have self-confirmed our inverters as products compliant to the Low Voltage Directive and place the CE mark on the inverters.

3) Outline of instructions

* In the 400V c la ss inverters, the rated input voltage range is three-phase, 380V

to 415V, 50Hz/60Hz.

* Connect the equipment to t h e e a r t h s e c u r e l y . Do no t u s e a n e a r t h leak age circuit

breaker as an electric shock protector without connecting the equipment to the earth.

* Wire the earth terminal independently. (Do not connect two or more cables to

one terminal.)

* The wire size on pages 19 and 21 are shown for following conditions

Ambient Temp : 40°C (104°F) maximum

Wire installation : On wall without ducts or conduits If conditions are different from above, select appropriate wire according to EN 60204 ANNEX C TABLE 5.

* Use the no-fuse breaker and magnetic contactor which conform to the EN or

IEC Standard.

Design notice :Where residual-current-operated protective device (RCD) is

used for protection in case of direct or indirect contact, only RCD of Type B is allowed on the supply side of this Electronic Equipment (EE). Otherwise another protective measure shall be applied such as separation of the EE from the environment by double or reinforced insulation or isolation of EE and supply system by a transformer. (Extract from EN51078)

* Use the inverter under the conditions of overvoltage category II and

contamination level 2 or higher specified in IEC664.

(a) To meet the overvoltage category II, insert an EN or IEC standard-

compliant earthed star connection isolation transformer in the input of the inverter.

(b) To meet the contamination level 2, install the inverter in a control box

protected against ingress of water, oil, carbon, dust, etc. (IP54 or higher).

* On the input and output of the inverter, use cables of the type and size set

forth in EN60204 Appendix C.

* The operating capacity of the relay outputs (terminal symbols A, B, C) should

be 30VDC, 0.3A.

* The terminals indicated as the input and output terminals for control circuit on

page 14 are isolated safely from the main circuit. Environment

3.3 Operation

3.3.1 Pre-operation checks

Before starting operation, check the following:

Safety

Perform test operation after making sure that safety is ensured if the machine should become out of control.

Machine

Make sure that the machine is free of damage.

Parameters

Set the parameter values to match the operating machine (system) environment.

Test operation

Perform test operation and make sure that the machine operates safely under light load at a low frequency. After that, start operation. Since the Pr. 240 "Soft-PWM setting" value is factory-set to select Soft-PWM control, the tone is different from that in the conventional non-low acoustic noise mode, this is not a fault.

Note:1. Indicates the parameter of which setting is ignored when the general-

purpose magnetic flux vector control mode is selected.

2. Since calibration is made before shipment from the factory, the settings differ slightly between inverters. The inverter is preset to provide a frequency

Parameter List

slightly higher than 60Hz.

3. When the control panel is used and the setting is 100Hz or more, the setting increments are 0.1Hz.

The setting increments are 0.01Hz when the communication made.

4. The setting depends on the inverter capacity: (0.1K to 3.7K)/(5.5K to 7.5K).

5. Set to 85% of the rated inverter current for the 0.1K to 0.75K.

6. If "2" is set in Pr. 77 (parameter write inhibit selection), the setting cannot be changed during operation.

7. The half-tone screened parameters allow their settings to be changed during operation if "0" (factory setting) has been set in Pr. 77 (parameter write inhibit selection). (However, the Pr. 72 and Pr. 240 values may be changed during PU operation only.)

8. The setting range changes with the inverter: 0.2kW to 7.5kW, 9999 for the 400V class.

9. Pr. 249 and Pr. 900 are not available for the 400V class.

10. Setting may be made on the 400V class inverter only.

11. The setting depends on the inverter capacity: 4% for the FR-E540-5.5K and

7.5K-NA.

12. For the FR-E540-5.5K and 7.5K-NA, the factory setting is 10s.

Note:1. When two or more motors are connected to the inverter, they cannot be

protected by the electronic overcurrent protection. Install an external thermal relay to each motor.

2. When the difference between the inverter and motor capacities is large and

the setting is small, the protective characteristics of the electronic overcurrent protection will be deteriorated. In this case, use an external thermal relay.

For operation in the high-frequency range, the current in the locked motor state is smaller than the rated output current of the inverter and the inverter does not result in an alarm (protective function is not activated) if the motor is at a stop. To improve this and activate the alarm, the stall prevention level can be reduced.

PARAMETERS

In Pr. 22, set the stall prevention operation level. Normally set it to 150% (factory setting). Set "0" in Pr. 22 to disable the stall prevention operation.

To reduce the stall prevention operation level in the high-frequency range, set the reduction starting frequency in Pr. 66 and the reduction ratio compensation factor in Pr. 23.

By setting "9999" (factory setting) in Pr. 23, the stall prevention operation level is constant at the Pr. 22 setting up to 400Hz.

Note: W hen the fast-response current limit has been set in Pr. 156 (factory setting

has the current limit activated), do not set the Pr. 22 value to 170% or more. Torque will not be developed by doing so.

Do not set a small value as the stall prevention operation current. Otherwise, torque generated will reduce.

Test operation must be performed.

acceleration/ deceleration B

Linear acceleration/deceleration is made up/down to the preset frequency (factory setting).

For machine tool spindles This setting is used when it is necessary to make acceleration/deceleration in a short time up to the base frequency or higher speed range. In this acceleration/deceleration pattern, f b (base frequency) is always the inflection point of an S shape, and you can set the acceleration/deceleration time according to the reduction in motor torque in the base frequency or higher constantoutput operation range.

For prevention of cargo collapse on conveyor, etc. This setting provides S-shaped acceleration/deceleration from f2 (current frequency) to f1 (target frequency), easing an acceleration/deceleration shock. This pattern has an effect on the prevention of cargo collapse, etc.
