There are several safety instructions in this manual which are marked with a special hazard alert symbol (flash or exclamation mark in the center of a triangle). Additionally, either the word CAUTION or WARNING is added following the triangle with the exclamation mark.

This symbol means hazardous high voltage. It is used to call your attention to items or operations that could be dangerous to your or other persons life. Please read the safety message carefully and follow all the instructions given.

This symbol is used to call your attention to situations which are potentially dangerous to persons. Please read the safety message carefully and follow all the instructions given.

The safety messages given following this symbol are further divided into two categories:

WARNING This message indicates a situation which may lead to serious injury or even

death if the instruction is not observed.

CAUTION This message indicates a situation which may lead to minor or moderate

injury, or damage of product.

HAZARDOUS HIGH VOLTAGE

Motor control equipment or electronic controllers are connected to hazardous line

voltages. When servicing drives and electronic controllers there migh exist exposed components with cases or protrusions at or above line potential. Extreme care should

be taken to protect against shock. For these reasons, the following safety guidelines should be observed: Stand on an insulating pad and make it a habit to use only one hand when checking

components. Disconnect power before checking controllers or performing

maintenance. Be sure that equipment is grounded properly. Wear safety glasses

whenever working on an electronic controller or rotating electrical equipment.

WARNING This equipment should be installed, adjusted and serviced only by qualified electrical

maintenace personnel familiar with the construction and operation of the equipment

and the hazards involved. Failure to observe this precaution could result in bodily

injury.

WARNING The user is responsible that all driven machinery, drive train mechanism not supplied

by Hitachi, Ltd., and process line material are capable of safe operation at an applied

frequency of 150% of the maximum selected frequency range to the AC motor. Failure

to do so can result in destruction of equipment and injury to personnel should a single

point failure occur.

WARNING HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER

BEFORE WORKING ON THIS CONTROL.

WARNING SEPARATE MOTOR OVERLOAD AND OVERCURRENT PROTECTION

DEVICES ARE REQUIRED TO BE PROVIDED IN ACCORDANCE WITH THE

SAFETY CODES REQUIRED BY JURISDICTIONAL AUTHORITIES.

CAUTION These instructions should be read and clearly understood before working on L100IP

series equipment.

CAUTION Proper grounds, disconnecting devices (e.g. fuses) and other safety devices and their

location are the responsibility of the user and are not provided by Hitachi, Ltd.

CAUTION DANGEROUS VOLTAGE EXISTS UNTIL THE POWER LIGHT ON THE

DIGITAL OPERATOR IS OFF.

CAUTION Rotating shafts and electrical potentials above ground level can be hazardous.

Therefore it is strongly recommended that all electrical work conform to the national

electrical codes and local regulations. Installation, maintenance and alignment should

be performed by qualified personnell only.

Factory recommended test procedures included in this instruction manual should be

followed. Always disconnect electrical power before working on the unit.

WARNING a) Any motor used must be of suitable rating.

b) Motors may have hazardous moving parts so that suitable protection must be

provided in order to avoid injury.

CAUTION Alarm connections may have hazardous live voltages even when the inverter is

disconnected. In case of removing the front cover for maintenance or inspection,

confirm that incoming power for alarm connections is surely disconnected.

CAUTION Main terminals or other hazardous terminals for any interconnection (terminals for

connecting the motor, contact breaker, filter etc.) must be inaccessible in end

installation.

CAUTION If the unit is used in a manner not specified by the manufacturer the protection

provided by the unit may be impaired..

All of the above instructions, together with any other requirements, reccommendations,

and safety messages highlighted in this manual must be strictly complied with for continued LVD

compliance.

NOTES ON EMC (ELECTRO MAGNETICAL COMPATIBILITY)

WARNING This equipment should be installed, adjusted and serviced by qualified personnel

familiar with construction and operation of the equipment and the hazards

involved. Failure to observe this precaution could result in bodily injury.

When using L100IP series inverters in EU countries, the EMC directive 89/336/EEC must be observed. To satisfy the EMC directive and to comply with the standard, the following provisions should be obeyed:

A) Environmental conditions for the inverter:

• Ambient temperature: -10°C to 40°C.

• Relative Humidity: 20% to 90% (no dew condensation)

• Vibrations: max. 5,9m/s

(0.6 g) at 10–55Hz.

• Location: 1000 meter or less altitude, indoors (no corrosive gas or dust).

B) The power supply to the L100IP inverter must conform to the conditions stated below. If one of the

conditions mentioned is not satisfied then an appropriate L100IP AC reactor will have to be installed.

• Voltage fluctuation +/-10% or less

• Voltage unbalance +/-3% or less

• Frequency variation +/-4% or less

C) Wiring

• Shielded wiring (screened cable) is required for motor wiring, and total length has to be kept to less

than 50m. When using motor cables longer than 50m L100IP motor filters should be installed. Directions for installing filters can be found in the L100IP installation manual.

• The carrier frequency setting must be less than 5 kHz to satisfy EMC requirements.

• Separate the mains circuit wiring from the wiring used for signals or process circuit. Please refer to

the L100IP installation manual.

D) Installation

• For L100IP series inverters, the filters described hereafter have to be used and the installation notes

have to be observed.

If installed according to the following directions, the frequency inverters comply with the following standards: Emmissions: EN 61800-3 (EN 55011 group 1, class B) Immunity: EN 61800-3, industrial environments

For the best possible damping of interference, special line filters have been developed which guarantee you easy assembly and installation along with the necessary electrical reliability. However, effective EMC is only ensured if the suitable filter is selected for the particular drive and installed in accordance with these EMC recommendations. Please order the appropriate filter when ordering L100IP inverter.

Note: All filters are designed for 50Hz/60Hz +/-5%.

The amount of line-conducted interference also increases as motor cable length increases. Adherence to the interference limits for line-conducted interference is guaranteed on following way:

• If maximum motor cable length is 10 m at maximum elementary frequency:

Class „B“.

• If maximum motor cable length is 20 m at elementary frequency 5 kHz:

Class „B“.

• If maximum motor cable length is 50 m at maximum elementary frequency:

Class „A“.

Observe the following provisions for an electromagnetically compatible setup of your drive system:

1. As user you must ensure that the HF impedance between frequency inverter, filter and ground is as small as possible.

• See to it that the connections are metallic and have the largest possible areas (zink-plated mounting

plates)

2. Conductor loops act like antennas, especially when they encompass large areas. Consequently:

• Avoid unnecessary conductor loops

• Avoid parallel arrangement of „clean“ and interference-prone conductors

3. Lay the motor cable and all analog and digital contol lines shielded.

• You should allow the effective shield area of these lines to remain as large as possible; i.e., do not

move the shield further away than absolutely necessary.

• With compact systems, if for example the frequency inverter is communicating with the steering unit,

in the same control cabinet connected at the same PE-potential, the screen of control lines should be put on, on both sides with PE. With branch systems, if for example the communicating steering unit is not in the same control cabinet and there is a distance between the systems, we recommend to put on the screen of control lines only on the side of the frequency inverter. If it is possible, direct in the cable entry section of the steering unit. The screen of motor cables always must be put on, on both sides with PE.

• The large area contact between shield and PE-potential you can realise with a metal PG screw

connection or a metallic mounting clip.

• Use only copper mesh cable (CY) with 85% coverage

• The shielding should not be interrupted at any point in the cable. If the use of reactors, contactors,

terminals or safety switches in the motor output is necessary, the unshielded section should be kept as small as possible.

• Some motors have a rubber gasket between terminal box and motor housing. Very often, the terminal

boxes, and particularly the threads for the metal PG screw connections, are painted. Make sure there is always a good metallic connection between the shielding of the motor cable, the metal PG screw connection, the terminal box and the motor housing, and carefully remove this paint if necessary.

4. Very frequently, interference is coupled in through installation cables. This influence you can minimize:

• Lay interfering cables separately, a minimum of 0.25 m from cables susceptible to interference.

• A particularly critical point is laying cables parallel over larger distances. If two cables intersect, the

interference is smallest if they intersect at an angle of 90°. Cables susceptible to interference should therefore only intersect motor cables, intermediate circuit cables, or the wiring of a rheostat at right angles and never be laid parallel to them over larger distances.

5. The distance between an interference source and an interference sink (interference-threatened device) essentially determines the effects of the emitted interference on the interference sink.

• You should use only interference-free devices and maintain a minimum distance of 0.25 m from the

drive.

6. Safety measures

• Ensure that the protective conductor terminal (PE) of the filter is properly connected with the protective

conductor terminal of the frequency inverter. An HF ground connection via metal contact between the housings of the filter and the frequency inverter, or solely via cable shield, is not permitted as protective conductor connection. The filter must be solidly and permanently connected with the ground potential so as to preclude the danger of electric shock upon touching the filter if a fault occurs. You can achieve this by connecting it with a grounding conductor of at least 10 mm² or connecting a second grounding conductor, connected with a separate grounding terminal, parallel to the protective conductor (the cross section of each single protective conductor terminal must be designed for the required nominal load).

Chapter 1 – Safety precautions

Installation

The following safety precautions are to be observed when installing the frequency inverter:

CAUTION Be sure to install the inverter on flame resistant material such as metal. Otherwise,

there is a danger of fire.

CAUTION Be shure not to place anything inflammable in the vicinity. Otherwise, there is a

danger of fire.

CAUTION Be sure not to let foreign matter (such as cut wire refuse, spatter from welding, iron

refuse, wires, dust etc.) enter the inverter. Otherwise, there is a danger of fire.

CAUTION Install the inverter in a room which is not exposed to direct sunlight and is well

ventilated. Avoid environments which tend to be high in temperature, high in humidity or which have dew condensation, as well as places with dust, corrosive gas, explosive or inflammable gas, grinding-fluid mist, salt damage etc. Otherwise, there is a danger of fire.

CAUTION The wall surface on which the inverter is mounted must be of a nonflammable

material, such as a steel plate.

Wiring

WARNING The inverter has to be grounded properly. Otherwise, there is a danger of fire.

WARNING Wiring work must only be carried out when the power supply is off. Otherwise,

there is a danger of electric shock and/or fire.

WARNING Before carrying out the wiring work, the inverter has to be mounted properly.

Otherwise, there is a danger of electric shock or injury.

CAUTION Make shure that the input voltage is as follows (please also refer to chapter 11): Single/three phase: 200~240V, 50/60Hz (models up to 2,2kW) Three phase: 380~460V, 50/60Hz

CAUTION Don´t connect AC power supply to the inverter output terminals U, V, and W or fan

supply terminals F, F. Otherwise, there is a danger of injury and/or fire.

CAUTION Remarks for using earth leakage circuit breakers in the mains supply:

Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a

higher leakage current against earth. Especially in the moment of switching this can cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier

Chapter 1 – Safety precautions

1-2

on the input side of the inverter there is the possibility to stall the switch-off function through amounts of DC current. For these reasons, the following items should be observed:

Only pulse current sensitive earth leakage circuit breakers which have a short term

delay and a higher trigger current (500mA) should be used. Other components should be secured with separate earth leakage circuit breakers. Earth leakage circuit breakers in front of an inverter´s rectifier are not an absolute protection against direct touching.

CAUTION Each phase of the power supply has to be provided with a fuse. Otherwise, there is a

danger of fire.

Control and operation

WARNING Be sure to turn on the input power supply only after closing the front case. While

being energized, don´t open the front case. Otherwise, there is a danger of electric shock.

WARNING Never operate the switches with wet hands. Otherwise, there is a danger of electric

shock.

WARNING If the retry mode is selected, the inverter may suddenly restart during a stop which

was caused by a trip. In such a case, be sure not to approach the machine. Provisions have to be taken that the driven motor or machine does not endanger personnell even in the case of a sudden restart. Otherwise, there is a danger of injury.

WARNING Even if the power supply is cut off for a short period of time, the inverter may restart

operation after the power supply has recovered if the operation command is given. If this may incur danger to personnell, provisions have to be made in order to prevent a restart after power recovery. Otherwise, there is a danger of injury.

WARNING The STOP key is effective only if the corresponding parameters have been set.

Otherwise, there is a danger of injury.

WARNING If a reset is carried out following a trip condition the motor will restart if the

operation command has been given. Be sure to acknowledge this trip condition with a reset only after confirming that no operation command is active. Otherwise, there is a danger of injury.

WARNING When the power to the inverter is turned on while the operation command is active

the motor starts immediately. So before turning power supply on be sure to confirm that no operation command is active.

WARNING If the inverter has been configured for the stop command not to be given using the

STOP key, pressing the STOP key does not stop the motor. In this case a separate emergency stop switch is necessary.

CAUTION Operate the motor and machine connected to the inverter only within the

manufacturer´s speed specifications. Otherwise, there is a danger of injury.

CAUTION If a motor is to be operated at a frequency higher than the standard setting value of

50 or 60Hz, be sure to check the allowable speed of the motor and the machine with each manufacturer, and operate them only after getting their consent.

CAUTION Check the following during and after the test run. Otherwise, there is a danger of

machine breakage:

Was the short cut bar between terminals +1 and + removed by mistake?

Was the running direction of the motor correct?

Was the inverter tripped during acceleration or deceleration?

Were the indications of the rpm and the frequency meter correct?

Were there any abnormal motor vibrations or noise?

Chapter 1 – Safety precautions

1-3

Maintenance and inspection

WARNING Before carrying out maintenance and inspection wait for at least five minutes after

having turned off the input power supply. Otherwise, there is a danger of electric shock.

WARNING When removing connectors (e.g. from fans and printed circuit boards) never pull the

attached wires. Otherwise, there is a danger of fire due to wire breakage and/or injury.

Others

CAUTION Withstand voltage tests and insulation resistance tests (megger tests) are executed

before the units are shipped, so that there is no need to conduct these tests before operation.

CAUTION Do not attach or remove wiring or connectors when power is applied. Also, do not

check signals (e.g. using a multimeter) during operation.

CAUTION Never stop motor operation by switching off the electromagnetic contactors on the

primary or secondary side of the inverter.

When there has been an instantaneous power failure, and if an operation instruction

has been given, then the inverter may restart operation after the power failure has ended. If there is a possibibility that such an occurrence may harm humans, then install an electromagnetic contactor on the primary (power supply) side of the inverter, so that the circuit does not allow automatic restarting after the power supply has recoverd. If the optional remote operator is used and the retry function has been selected, this will also cause automatic restarting when an operation instruction has been input, so please be careful.

CAUTION PROTECTION AGAINST NOISE INTERFERENCE FROM THE INVERTER

L100IP series inverters use many semiconductor switching elements such as

transistors and IGBTs. For this reason, a radio set or measuring instrument located near the inverter is susceptible to noise interference. To protect the instruments from erreneous operation due to noise interference produced by the inverter, they should be

Added EMI filter on the input side of the inverter also reduces the effect of noise from

commercial power lines on external devices (refer to figure above).

CAUTION EFFECTS OF DISTRIBUTER LINES ON INVERTERS

In the cases mentioned below involving a general purpose inverter, a large peak

current flows on the power supply side, sometimes destroying the converter module: A) The unbalance factor of the power supply is 3% or higher. B) The power supply capacity is set at least ten times greater than the inverter

capacity (i.e. 500kVA or more)

C) When abrupt power supply changes are to be expected. Some examples:

1) Several inverters are interconnected using a short bus to the same power

supply.

2) A thyristor converter and an inverter are interconnected using a short bus.

3) An installed power factor compensating device is connected or disconnected.

In the cases mentioned above we recommend installing an AC reactor of 3% voltage drop at rated current with respect to the supply voltage on the power supply side.

CAUTION When an EEPROM error occurs (trip E 08) all parameter values have to be checked

for correctness (especially the RS input).

CAUTION When the intelligent digital inputs FW or RV are configured as normally closed

contact (standard setting is normally open), then the inverter starts automatically. Do not configure these inputs as normally closed inputs unless absolutely necessary.

CAUTION Factory setting of the carrier frequency is different for diferent types of the inverter.

This setting is at the same time also highest allowable carrier frequency without derating output power. See bottom of the terminal cover for reference.

GENERAL NOTICE

In all the illustrations and figures in this manual, covers and safety devices are

occasionally omitted in order to better describe the details. When the inverter is operated make shure that all the covers and safety devices are placed in their correct positions.

Explanation of IP54 protection provided by enclosure

Generally, the enclosure must provide sufficient protection for persons who use them and for equipment itself. IP54 enclosure provides protection to some extent and it is not foreseen for very severe environmental conditions. Here is the explanation of the two digits:

Protection of persons against access to hazardous parts inside the enclosure indicated by the first characteristic numeral 5:

Protected against access to hazardous parts with wire.

Protection of the equipment inside the enclosure against ingress of solid foreign objects indicated by the first characteristic numeral 5:

Dust-protected: Ingress of dust is not totally prevented, but dust shall not penetrate in a quantity to interfere with satisfactory operation of the apparatus or to impair safety.

The inverter shall not be exposed to severe environmental conditions for more than 8 h (test condition).

Protection of the equipment inside the enclosure against harmful effects due to the ingress of water indicated by the second characteristic numeral 4:

Protected against splashing water: Water splashed against the enclosure from any direction shall have no harmful effects.

The inverter shall not be exposed to splashing water for more than 10 minutes (test condition).

The unit is not intended for outdoor usage.

Other than in the time specified above, inverter must be operated in the condition of 90% humidity or less.

WARNING the above explanation is intended as an indication. Refer always to the a.m.

standard in the case of any doubt.

Chapter 4 – Installation

4-2

The inverter must be mounted vertically on a non-flammable wall in order to prevent from overheating and fire. The minimum clearances to the surrounding walls shown in the figure below must be complied with to ensure a good ventilation. Foreign matter (especially conductive objects) must nut be dropped into the inverter since they not only cause malfunction and damage but may also lead to electrical and fire hazards.

Cover all ventilation holes on the inverter during installation so that no foreign objects can enter the inverter. Be sure to remove those covers from the inverter before you put the inverter to work.

The minimum clearances to the surrounding walls shown in the figure are only meant for reference. A more compact installation (back to back or side by side) may well be possible and should be discussed with Hitachi. Please always leave enough room for the teminal cover to be opened without problems in order to connect wires to the control terminals.

The ambient temperature should be in the range of -10°C to 40°C. Higher ambient temperature causes shorter inverter life. So if there is hot equipment in the vicinity of the inverter, keep it away from the inverter as far as possible.

The end application must be in accordance with the BS EN 60204-1 standard.

Chapter 5 – Wiring

CAUTION Fasten the screws with the specified fastening torque so that they will not loosen

unintentionally. Check all terminals for loose screws. Otherwise there is a danger of fire.

CAUTION Remarks for using earth leakage circuit breakers in the mains supply

Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a

higher leakage current against earth. Especially in the moment of switching this can cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier on the input side of the inverter there is the possibility to stall the switch-off function through amounts of DC current. For these reasons, the following items should be observed:

Only pulse current sensitive earth leakage circuit breakers which have a short term

CAUTION Each phase of the power supply has to be provided with a fuse. Otherwise, there is a

danger of fire.

CAUTION As for motor leads, earth leakage breakers, and electromagnetic contactors, be sure to

use the ones that have the correct rating. Otherwise, there is a danger of fire.

CAUTION Make sure that the mains supply leads are reliably fixed.

Wiring the power supply and motor

In order to connect cables to the power supply and other terminals the terminal cover has to be opened. For this, first of all the four corresponding screw has to be loosened. The location of the terminals is depicted in the figure below:

CAUTION Don’t disconnect wires attached to F terminals (fan power supply), otherwise

inverter may overheat. In case the wires are exchanged, the fan doesn’t work. This terminals cannot be used for the power supply for external device.

When connecting cables, the following details have to be considered:

1) Power supply cables must only be connected to the terminals L1, L2, L3 or L, N.

2) Refer the page 5-5 for wiring equipment and options.

General remarks

When connecting cables, the following items must be observed:

- When changing the power supply of the motor between the inverter and commercial power line, be sure

to install mechanically interlocked switches (S1 and S2) as shown in the figure below:

Motor

Inverter

Earth leakage

circuit breakers

L1 (L) L2 L3 (N)

U V

Power

supply

- Install an earth leakage breaker at the input of the inverter. Select an earth leakage breaker which has a

short term delay and a higher trigger current.

When the cable between the inverter and the motor is more than 10 meters long, the thermal relay may malfunction due to high-frequency waves. To prevent this, install an AC reactor on the output side of the inverter or use a current sensor rather than a thermal relay.

- In case a relay is connected to the digital output terminals 11 or 12 be sure to install a surge absorbing

diode in parallel to the relay. Otherwise the surge voltage created when the relay goes on or off may damage the output circuit.

- Be sure that the specified grounding is carried out. Separate the inverter´s grounding pole from those of

other heavy electric machinery and avoid using common grounding poles when multiple inverters are employed.

- Use a twisted and shielded wire when connecting signal lines to the control terminals and cut the

shielded covering as shown in the figure below. Make sure that the length of the signal line is 20 m or less. If the line must be longer than 20 m then an appropriate signal amplifier should be used.

- Use relays which are capable of reliably switching at a voltage of 24VDC and a current of 3mA.

- Install the mains circuit cables at a safe distance from the control circuit cables. If the mains circuit

cables and the control circuit cables have to cross each other, this should be done at an angle of 90 degrees because interference can be minimized in this case.

Wiring equipment and options

CAUTION A switch or circuit breaker shall be included in the building installation. It shall be

marked as the disconnecting device for the equipment and should meet the requirements of the IEC947-1 and IEC947-3 standard. Ratings should be in accordance with table below. For single phase there should be a double pole and for three phase there should be a three pole disconnecting device. The switch or circuit breaker should be near the equipment (close proximitly to the equipment and in easy reach to the operator).

CAUTION Provide the wiring equipment in accordance with the safety codes required by

jurisdictional authorities (IEC example: supply wires should meet the requirements of the IEC 60227 or IEC 60245... They should be made of suitable heat-resistant material). If specified in standards or laws and regulations, follow their istructions. In the following table some guidelines for choosing an appropriate wire gauge are presented:

Notes:

- Field wiring connections for PE wire must be made by a certified closed-loop terminal connector sized

for the wire gauge involved. The connector must be fixed using the crimp tool specified by the connector manufacturer.

- Only use a fuse that has the appropriate rated current.

- Be sure to use bigger wires for mains circuit cables and motor cables if the distance exceeds 20m.

- Tighten firmly the cable gland nuts after pulling through the cable. The round rubber protection is to be

removed before wiring. Leave rubber protectection in unused glads in order to keep IP54 protection.

Use max. 1,5mm2 for the alarm signal wire. The wire stripping length should be approximately 6–7 mm.

Part description Function

AC reactor

This part is used when the unbalance ratio is 3% or

more and the power supply is 500kVA or more, and

there are rapid changes in the power supply. This part

also improves the power factor.

EMI filter

(Note)

This part is used to conform with the applicable

EMC standards.

Radio noise filter

This part reduces noise generated at the output of the inverter (this type of filter supplies an almost perfect sine shaped output voltage between phase-phase and

phase-PE).

Motor filter

Motors that are driven by an inverter are to a larger

extent subject to voltage fluctuations than motors directly

driven (without inverter) by power lines. An AC reactor

installed between inverter output and motor smoothens motor run and so reduces torque ripple. When the cable between the inverter and the motor is too long, this part

also forces the voltage dv/dt to be limited and so protects

the isolation of the motor.

Note: Usage of an EMI filter is necessary for the European EMC directive, for the Australian C-TICK and others. In comparison, the other parts mentioned in the table above are not intended for this special use.

Chapter 6 – General operation notes

Before starting operation

Prior to the test run, the following items should be checked:

1) Make sure that the power lines (input power supply terminals L1, L2, L3 or L, N) and output terminals

(U, V and W) are connected correctly.

2) Make sure that there are no mistakes in the signal line connections.

3) The grounding terminal must be grounded.

4) Terminals other than those marked as grounding terminals must not be grounded.

5) The inverter must be installed vertically on a non-flammable mounting surface (e.g. steel).

6) Remove any residue from wiring work like stray pieces of wire and others. Also, make sure that no tolls

are left behind.

7) Make shure that the wires connected to the output terminals are not short-circuited or grounded.

8) All the terminal screws must be sufficiently tightened.

9) The configurable maximum output frequency parameter must be chosen in accordance with the

maximum frequency of the connected motor and machine.

Do not carry out any withstand voltage tests because the inverter has a surge absorber between the mains circuit terminals and the ground.

Test run

Below an example for an inverter connection is shown. For the initial tests, frequency adjustment and forward and reverse running commands should be carried out via the digital operator in order to check the inverter’s correct functioning.

In order to test the inverter, follow the procedure described below:

1) Turn on power supply to the inverter. The power LED on the digital operator will light up.

2) Set function A 02 to 02.

3) Set function A 01 to 02. Set the corresponding frequency using function F 01.

4) After pressing the RUN key the motor starts to run and the the RUN lamp lights up.

5) The actual frequency can be monitored using function d 01.

6) You can stop the test run by pressing the STOP key.

CAUTION After the test run has been completed, check the following items to ensure that the

motor will not be damaged:

Was the direction of the motor run correct? Was there any trip condition during

acceleration or deceleration? Were there any unusual motor sounds or vibrations?

When a trip occured during the test run due to overcurrent or overvoltage, increase

acceleration or deceleration time.

Prevention of restart

When the USP input is on, the motor does not restart when power supply recovers

following a power supply failure and a running command is active at the same time.

(18)

Reset

A trip can be acknowledged by activating the RS input. If a reset is given during

normal inverter operation, the motor runs free. The RS input is always a normally

open contact and cannot be configured as normally closed input.
