WARNING

CAUTION

This Instruction Manual (Applied) provides instructions for advanced use of the FR-D700-G series drive units. Incorrect handling might cause an unexpected fault. Before using the drive unit, always read this Instruction Manual and the Instruction Manual (Basic) [IB-0600477ENG] packed with the product carefully to use the equipment to its optimum performance.

2. Fire Prevention

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the drive unit until you have read through the Instruction Manual and appended documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".

Incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.

1. Electric Shock Prevention

 While the drive unit power is ON, do not remove the front

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

 Even if power is OFF, do not remove the front cover except

for wiring or periodic inspection. You may accidentally touch the charged drive unit circuits and get an electric shock.

 Before wiring or inspection, power must be switched OFF.

To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring or inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.

 This drive unit must be earthed (grounded). Earthing

(grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 61140 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class drive unit in compliance with EN standard must be used.

 Any person who is involved in wiring or inspection of this

equipment shall be fully competent to do the work.

 The drive unit must be installed before wiring. Otherwise

you may get an electric shock or be injured.

 Setting dial and key operations must be performed with dry

hands to prevent an electric shock. Otherwise you may get 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.

 Do not touch the printed circuit board or handle the cables

with wet hands. Otherwise you may get an electric shock.

 When measuring the main circuit capacitor capacity, the DC

voltage is applied to the motor for 1s at powering OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.

 A

PM motor is a synchronous motor with embedded magnets. High-voltage is generated at motor terminals while the motor is running even after the drive unit power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. For applications where the motor is driven by the load, the low-voltage manual contactor, which is installed at the drive unit's output side, must be opened before wiring or inspection. Otherwise you may get an electric shock.

 The drive unit must be installed on a nonflammable wall

without holes (so that nobody touches the drive unit heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

 If the drive unit has become faulty, the drive unit power must

be switched OFF. A continuous flow of large current could cause a fire.

 When using a brake resistor, a sequence that will turn OFF

power when a fault signal is output must be configured. Otherwise the brake resistor may overheat due to damage of the brake transistor and possibly cause a fire.

 Do not connect a resistor directly to the DC terminals P/+

and N/-. Doing so could cause a fire.

 Be sure to perform daily and periodic inspections as

specified in the Instruction Manual. If a product is used without any inspection, a burst, breakage, or a fire may occur.

3.Injury Prevention

 The voltage applied to each terminal must be the ones

specified in the Instruction Manual. Otherwise burst, damage, etc. may occur.

 The cables must be connected to the correct terminals.

Otherwise burst, damage, etc. may occur.

 Polarity must be correct. Otherwise burst, damage, etc. may

occur.

 While power is ON or for some time after power-OFF, do not

touch the drive unit since the drive unit will be extremely hot. Doing so can cause burns.

motor is running even after the power is turned OFF. Before wiring, the PM motor must be confirmed to be stopped. Otherwise you may get an electric shock.

Applying the commercial power supply to input terminals (U, V, W) of a PM motor will burn the PM motor. The PM motor must be connected with the output terminals (U, V, W) of the drive unit.

(3) Trial run

 Before starting operation, each parameter must be

confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.

(4) Usage

 A PM motor and the drive unit must be used in the specified

capacity combination.

 Do not use multiple PM motors with one drive unit.  Any person must stay away from the equipment when the

retry function is set as it will restart suddenly after trip.

 Since pressing the STOP/RESET key may not stop output

depending on the function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided.

 OFF status of the start signal must be confirmed before

resetting the drive unit fault. Resetting drive unit alarm with the start signal ON restarts the motor suddenly.

 Do not use a PM motor in an application where a motor is

driven by its load and runs at a speed higher than the maximum motor speed.

 According to the motor to be connected, perform PM

parameter initialization. Incorrect initial setting of parameters may damage the motor. The parameters for motor operation are initially set for an SPM geared motor. When other PM motors are used, set parameters according to the motor.

 Do not use the drive unit for a load other than the PM motor.

Connection of any other electrical equipment to the drive unit output may damage the equipment.

 Do not modify the equipment.

Do not perform parts removal which is not instructed in this



manual. Doing so may lead to fault or damage of the product.

 The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is recommended to install an external thermal for overheat protection.

 Do not use a magnetic contactor on the drive unit input for

frequent starting/stopping of the drive unit. Otherwise, the life of the drive unit decreases.

 The effect of electromagnetic interference must be reduced

by using an EMC filter or by other means. Otherwise nearby electronic equipment may be affected.

 Appropriate measures must be taken to suppress

harmonics. Otherwise power supply harmonics from the drive unit may heat/damage the power factor correction capacitor and generator.

 When parameter clear or all parameter clear is performed,

the required parameters must be set again before starting operations because all parameters return to the initial value.

 The drive unit can be easily set for high-speed operation.

Before changing its setting, the performances of the motor and machine must be fully examined.

 Stop status cannot be hold by the drive unit's brake

function. In addition to the drive unit's brake function, a holding device must be installed to ensure safety.

 Before running a drive unit which had been stored for a long

period, inspection and test operation must be performed.

 Static electricity in your body must be discharged before

you touch the product. Otherwise the product may be damaged.

 In the system with a PM motor, the drive unit power must be

turned ON before closing the contacts of the contactor at the output side.

 If you are installing the drive unit to drive a three-phase

device while you are contracted for lighting and power service, consult your electric power supplier.

(5) Emergency stop

CAUTION

 A safety backup such as an emergency brake must be

provided for devices or equipment in a system to prevent hazardous conditions in case of failure of the drive unit or an external device controlling the drive unit.

 When the breaker on the drive unit input side trips, the

wiring must be checked for fault (short circuit), and internal parts of the drive unit for a damage, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.

 When any protective function is activated, appropriate

corrective action must be taken, and the drive unit must be reset before resuming operation.

(6) Maintenance, inspection and parts replacement

 Do not carry out a megger (insulation resistance) test on the

control circuit of the drive unit. It will cause a failure.

(7) Disposal

 The drive unit must be treated as industrial waste.

Drive unit and peripheral devices

NOTE

 The life of the drive unit is influenced by surrounding air temperature. Pay attention to the surrounding air

temperature. This must be noted especially when the drive unit is installed in an enclosure. (

 Wrong wiring might lead to damage of the drive unit. The control signal lines must be kept fully away from the main

circuit to protect them from noise. (Refer to page 14.)

 Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) on the drive unit output

side. This will cause the drive unit to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them.

 Electromagnetic wave interference

The input/output (main circuit) of the drive unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the drive unit. In this case, install the FR-BIF optional noise filter (capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize interference. (

 Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.  A PM motor cannot be driven by the commercial power supply.  A PM motor is a magnet motor. High-voltage is generated at motor terminals while the motor is running even after the

drive unit power is turned OFF. Before closing the contactor on the output side, make sure that the drive unit power is ON and the motor is stopped.

Installation of the drive unit and enclosure design

1.4 Installation of the drive unit and enclosure design

When a drive unit enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the enclosure structure, size and equipment layout. The drive unit unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the drive unit in the ambient environment that completely satisfies the equipment specifications.

1.4.1 Drive unit installation environment

As the drive unit installation environment should satisfy the standard specifications indicated in the following table, operation in any place that does not meet these conditions not only deteriorates the performance and life of the drive unit, but also causes a failure. Refer to the following points and take adequate measures.

Environmental standard specifications of drive unit

Vibration

(1) Temperature

The permissible surrounding air temperature of the drive unit is between -10°C within this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures so that the surrounding air temperature of the drive unit falls within the specified range.

1) Measures against high temperature

 Use a forced ventilation system or similar cooling system. (Refer to page 10.)

 Install the panel in an air-conditioned electrical chamber.

 Block direct sunlight.

 Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.

 Ventilate the area around the panel well.

°C to +50°C

-10

5.9m/s

(non-freezing)

or less at 10 to 55Hz (directions of X, Y, Z axes)

and +50°C

. Always operate the drive unit

2) Measures against low temperature

 Provide a space heater in the enclosure.

 Do not power OFF the drive unit. (Keep the start signal of the drive unit OFF.)

3) Sudden temperature changes

 Select an installation place where temperature does not change suddenly.

 Avoid installing the drive unit near the air outlet of an air conditioner.

 If temperature changes are caused by opening/closing of a door, install the drive unit away from the door.

(2) Humidity

Normally operate the drive unit within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to 85%.

1) Measures against high humidity

 Make the panel enclosed, and provide it with a hygroscopic agent.

 Take dry air into the enclosure from outside.

 Provide a space heater in the enclosure.

2) Measures against low humidity

What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity)

beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into

the enclosure from outside.

3) Measures against condensation

Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside-

air temperature changes suddenly.

Condensation causes such faults as reduced insulation and corrosion.

 Take the measures against high humidity in 1).

 Do not power OFF the drive unit. (Keep the start signal of the drive unit OFF.)

OUTLINE

Installation of the drive unit and enclosure design

(3) Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to

moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter. In the atmosphere

where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in

a short time.

Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Countermeasures

 Place in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 10.)

 Purge air.

Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.

(4) Corrosive gas, salt damage

If the drive unit is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the

relays and switches will result in poor contact.

In such places, take the measures given in Section 3.

(5) Explosive, flammable gases

As the drive unit is non-explosion proof, it must be contained in an explosion proof enclosure. In places where explosion may

be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and

has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to

avoid installation in such places and install the drive unit in a non-hazardous place.

(6) Highland

Use the drive unit at the altitude of within 1000m. If it is used at a higher place, it is likely that thin air will reduce the cooling

effect and low air pressure will deteriorate dielectric strength.

(7) Vibration, impact

The vibration resistance of the drive unit is up to 5.9m/s2 at 10 to 55Hz frequency and 1mm amplitude for the directions of X,

Y, Z axes. Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or

cause poor contact to the connectors.

Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.

Countermeasures

 Provide the panel with rubber vibration isolators.

 Strengthen the structure to prevent the enclosure from resonance.

 Install the enclosure away from sources of vibration.

1.4.2 Cooling system types for drive unit enclosure

From the enclosure that contains the drive unit, the heat of the drive unit and other equipment (transformers, lamps, resistors,

etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the

permissible temperatures of the in-enclosure equipment including the drive unit.

The cooling systems are classified as follows in terms of the cooling calculation method.

1) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)

2) Cooling by heat sink (aluminum fin, etc.)

3) Cooling by ventilation (forced ventilation type, pipe ventilation type)

4) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

NOTE

 When encasing multiple drive units, install them in parallel as a

cooling measure.

 Install the drive unit vertically.

 For heat dissipation and maintenance, allow minimum clearance

shown in the figures below from the drive unit to the other devices

and to the inner surface of the enclosure.

Refer to the clearance

shown on the left.

Vertical

* When using the drive units at the surrounding air temperature of 40C or less, the drive units can be installed without any clearance between

1.5.1 Installation precautions

(1) Above drive unit

Heat is blown up from inside the drive unit by the small fan built in the unit. Any equipment placed above the drive unit should

be heat resistant.

(2) Arrangement of multiple drive units

When multiple drive units are placed in the same

enclosure, generally arrange them horizontally as shown

in the right figure (a). When it is inevitable to arrange

them vertically to minimize space, take such measures as

to provide guides since heat from the bottom drive units

can increase the temperatures in the top drive units,

causing drive unit failures.

When mounting multiple drive units, fully take caution not

to make the surrounding air temperature of the drive unit

higher than the permissible value by providing ventilation

and increasing the enclosure size.

Arrangement of multiple drive units

(3) Arrangement of ventilation fan and drive unit

Heat generated in the drive unit is blown up from the bottom of

the unit as warm air by the cooling fan. When installing a

ventilation fan for that heat, determine the place of ventilation

fan installation after fully considering an air flow. (Air passes

through areas of low resistance. Make an airway and airflow

plates to expose the drive unit to cool air.)

NOTE

 Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short

circuit or malfunction. A screw that has been tightened too tightly can cause a short circuit or malfunction due to the

unit breakage.

 Use crimp terminals with insulation sleeve to wire the power supply and motor.

The line voltage drop can be calculated by the following formula:

Line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

(2) Earthing (Grounding) precautions

 Always earth (ground) the motor and drive unit.

1) Purpose of earthing (grounding)

Generally, an electrical apparatus has an earthing (grounding) terminal, which must be connected to the ground before

use.

An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture

an insulating material that can shut off a leakage current completely, and actually, a slight current flow into the case.

The purpose of earthing (grounding) the case of an electrical apparatus is to prevent operator from getting an electric

shock from this leakage current when touching it.

To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers

and other apparatuses that handle low-level signals or operate very fast.

2) Earthing (grounding) methods and earthing (grounding) work

As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noise-

affected malfunction prevention type. Therefore, these two types should be discriminated clearly, and the following

work must be done to prevent the leakage current having the drive unit's high frequency components from entering the

malfunction prevention type earthing (grounding):

(a)If possible, use (l) independent earthing (grounding) in figure below for the drive unit. If independent earthing

(grounding) is not available, use (ll) common earthing (grounding) in the figure below where the drive unit is connected with the other equipment at an earthing (grounding) point. The (lll) common earthing (grounding) cable as in the figure below, which drive unit shares a common earthing (grounding) cable with the other equipment, must be avoided. A leakage current including many high frequency components flows in the earthing (grounding) cables of the drive unit and drive unit-driven motor. Therefore, use the independent earthing (grounding) and separate the earthing (grounding) cable of the drive unit from equipment sensitive to EMI. In a high building, it may be effective to use the EMI prevention type earthing (grounding) connecting to an iron structure frame, and electric shock prevention type earthing (grounding) with the independent earthing (grounding) together.

(b)This drive unit must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and

local safety regulations and electrical codes. (NEC section 250, IEC 61140 class 1 and other applicable standards). Use an neutral-point earthed (grounded) power supply for 400V class drive unit in compliance with EN standard.

(c)Use the thickest possible earthing (grounding) cable. The earthing (grounding) cable size should be no less than the

size indicated in the table on page 16.

(d)The earthing (grounding) point should be as close as possible to the drive unit, and the earthing (grounding) cable

length should be as short as possible.

(e)Run the earthing (grounding) cable as far away as possible from the I/O wiring of equipment sensitive to noises and

run them in parallel in the minimum distance.

POINT

To be compliant with the EU Directive (Low Voltage Directive), refer to the Instruction Manual (Basic).

(3) Total wiring length

Connect a PM motor within the total wiring length of 30m. Use one PM motor for one drive unit. Multiple PM motors cannot be connected to a drive unit.

NOTE

 Especially for long-distance wiring, the drive unit may be affected by a charging current caused by the stray

Drive unit

(II)Common earthing (grounding).......Good

capacitances of the wiring, leading to a malfunction of the overcurrent protective function or the stall prevention

function, or a malfunction or fault of the equipment connected on the drive unit's output side. If malfunction of stall

prevention function occurs, increase the stall level. (Refer to page 83 for Pr. 22 Stall prevention operation level and Pr. 156 Stall

prevention operation selection.)
