● Do no

t touch the printed circuit board or handle the cables with wet hands. You may get

an electric shock.

Fire prevention

CAUTION:

● Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mounting it to or near combustible material can cause a fire.

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

● Do not connect a resistor directly to the DC terminals P/+, N/–. This could cause a fire and destroy the inverter. The surface temperature of braking resistors can far exceed 100°C for brief periods. Make sure that there is adequate protection against accidental contact and a safe distance is maintained to other units and system parts.

Injury prevention

CAUTION:

● Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.

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

● Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur.

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

CAUTION:

● When carrying products, use correct lifting gear to prevent injury.

● Do not stack the inverter boxes higher than the number recommended.

● Ensure that installation position and material can withstand the weight of the

inverter. Install according to the information in the instruction manual.

● Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.

● When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.

● Do not stand or rest heavy objects on the product.

● Check the inverter mounting orientation is correct.

● Prevent other conductive bodies such as screws and metal fragments or other

flammable substance such as oil from entering the inverter.

Operation

WARNING:

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

● Since pressing STOP/RESET key may not stop output depending on the function setting status, provide a circuit and switch separately to make an emergency stop (power off, mechanical brake operation for emergency stop, etc.).

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

● The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that depending on the settings of the communications parameters it may not be possible to stop the system via these connections if there is an error in the communications system or the data line. In configurations like this it is thus essential to install additional safety hardware that makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal, external motor contactor etc). Clear and unambiguous warnings about this must be posted on site for the operating and service staff.

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

CAUTION:

● The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection.

● Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise, the life of the inverter decreases.

● Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for proper installation of frequency inverters. Otherwise nearby electronic equipment may be affected.

● Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.

● Use a motor designed for inverter operation. (The stress for motor windings is bigger than in line power supply).

● When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter returns to the initial value.

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

● The DC braking function of the frequency inverter is not designed to continuously hold a load. Use an electro-mechanical holding brake on the motor for this purpose.

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

● For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body.

Diagnosis and settings

CAUTION:

● Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions.

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.

● When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker.

● When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding corrective action as described in the inverter manual, then reset the inverter, and resume operation.

Maintenance, inspection and parts replacement

CAUTION:

● Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure.

Disposing the inverter

CAUTION:

● Treat as industrial waste.

Installation Enclosure design

2.4 Enclosure design

When an inverter 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 inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.

2.4.1 Inverter installation environment

As the inverter 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 inverter, but also causes a failure. Refer to the following points and take adequate measures.

−10°C to +30°C (non-freezing)

Tab. 2-1: Environmental standard specifications of inverter

Temperature

The permissible ambient temperature of the inverter FR-F740 is between −10 and +50°C (when LD is set) or −10 and +40°C (when SLD is set) and of the inverter FR-F746 is between −10 and +40°C (when LD is set) or −10 and +30°C (when SLD is set). Always operate the inverter 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 ambient temperature of the inverter falls within the specified range.

● Measures against high temperature

– Use a forced ventilation system or similar cooling system. (Refer to page 2-10.)

– Install the enclosure 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 enclosure well.

● Measures against low temperature

– Provide a space heater in the enclosure.

– Do not power off the inverter. (Keep the start signal of the inverter off.)

● Sudden temperature changes

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

– Avoid installing the inverter near the air outlet of an air conditioner.

– If temperature changes are caused by opening/closing of a door, install the inverter away

from the door.

FR-F700 EC 2 - 7

Enclosure design Installation

Humidity

Normally operate the inverter 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%.

● Measures against high humidity

– Make the enclosure enclosed, and provide it with a hygroscopic agent.

– Take dry air into the enclosure from outside.

– Provide a space heater in the enclosure.

● 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.

● 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.

– Do not power off the inverter. (Keep the start signal of the inverter off.)

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.

● Measures against dust, dirt, oil mist

– Place in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 2-10.)

– Purge air.

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

Corrosive gas, salt damage

If the inverter 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 against dust, dirt, oil mist.

2 - 8

Installation Enclosure design

Explosive, flammable gases

As the inverter 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 inverter in a non-hazardous place.

Highland

Use the inverter 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.

Vibration, impact

The vibration resistance of the inverter is up to 5.9m/s² (2.9m/s² for the 04320 or more) 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 enclosure with rubber vibration isolators.

– Strengthen the structure to prevent the enclosure from resonance.

– Install the enclosure away from sources of vibration.

Cooling system types for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter 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 inenclosure equipment including the inverter. The cooling systems are classified as follows in terms of the cooling calculation method.

● Cooling by natural heat dissipation from the enclosure surface (Totally enclosed type)

● Cooling by heat sink (Aluminium fin, etc.)

● Cooling by ventilation (Forced ventilation type, pipe ventilation type)

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

Fig. 2-10: Clearances

NOTES

NOTE

For replacing the cooling fan of the 04320 or more, 30cm of space is necessary in front of the inverter. Refer to section 8.1.7 for fan replacement.

Since the fan cover of the inverter FR-F746 is fixed with screws, leave enough clearances so that the screws can be removed with a driver and such.

It is not necessary to leave spaces on both sides of the inverter FR-F746.

Inverter mounting orientation

Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.

Above the inverter

Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be heat resistant.

The ambient temperature should be 50°C or less for the inverter FR-F740 and 40°C or less for the inverter FR-F746 at a distance of 5cm from the centre bottom of the inverter.

Arrangement of multiple inverters

When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the 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 inverters can increase the temperatures in the top inverters, causing inverter failures.

I001006E

Fig. 2-11: Arrangement of multiple inverters

NOTE When mounting multiple inverters, fully take caution not to make the ambient temperature of

the inverter higher than the permissible value by providing ventilation and increasing the enclosure size.

Placement of ventilation fan and inverter

Heat generated in the inverter 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 inverter to cool air.)

2.4.3 Heatsink protrusion attachment (FR-A7CN)

When encasing the inverter in an enclosure, the generated heat amount in an enclosure can be greatly reduced by installing the heatsink portion of the inverter outside the enclosure. When installing the inverter in a compact enclosure, etc., this installation method is recommended.

For the FR-F740-00023 to 03610, a heatsink can be protruded outside the enclosure using a heatsink protrusion attachment (FR-A7CN). For a panel cut dimension drawing and an installation procedure of the heatsink protrusion attachment (FR-A7CN) to the inverter, refer to a manual of "heatsink protrusion attachment".

For the panel cut dimensions of the inverters FR-F740-04320 and more refer to Fig. A-18 in the appendix. The heatsink protrusion attachment is not required for external cooling of these inverters.

Shift and removal of a rear side installation frame

● FR-F740-05470 to 06830

One installation frame is attached to each of the upper and lower part of the inverter. Change the position of the rear side installation frame on the upper and lower side of the inverter to the frontside as shown below. When changing the installation frames, make sure that the installation orientation is correct.

Wiring Inverter and peripheral devices

3-phase AC power supply

Use within the permissible power supply specifications of the inverter. (Refer to Appendix A.)

Moulded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse

The breaker must be selected carefully since an in-rush current flows in the inverter at power on. (Refer to section 3.1.1.)



Reactor (FR-BAL-B, FFR-HEL-(H)-E)

Reactors (option) should be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (1000kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. For the 01160 or less, remove the jumpers across terminals P/+ and P1 to connect to the DC reactor. (Refer to section 3.7.6.)

Inverter (FR-F700 EC)

The life of the inverter is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. Especially when mounting the inverter inside an enclosure, take cautions of the ambient temperature. (Refer to section 2.4.2.)

Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit to protect them from noise. (Refer to section 3.2.)

Refer to section 3.8.3 for the builtin EMC filter.

NOTES Do not install a power factor correction capacitor or surge suppressor on the inverter output

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

Electromagnetic Compatibility Operation of the frequency inverter can cause electromagnetic interference in the input and output that can be propagated by cable (via the power input lines), by wireless radiation to nearby equipment (e.g. AM radios) or via data and signal lines. Activate the integrated EMC filter (and an additional optional filter if present) to reduce air propagated interference on the input side of the inverter. Use AC or DC reactors to reduce line propagated noise (harmonics). Use shielded motor power lines to reduce output noise (refer also to section 3.8 "Electromagnetic Compatibility").

Fig. 3-5: Combed shaped wiring cover

Cut off the same numbers of lugs as wires. If you cut off unnecessary parts and no wires are connected, the protective structure (JEM 1030) of the inverter becomes open type (IP00).

Cable bushing FR-F746

Remove the rubber bushing and use the cable gland (equivalent for SKINTOP ST-M series, locknuts GMP-GL-M series and gaskets GMP series, LAPP) so that cable wiring satisfies IP54.

For a hole in which the cable is not led, the rubber bush may be used without replacing.

Wiring Main circuit connection

Cables and wiring length

Select the recommended cable size to ensure that a voltage drop will be 2% max. 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.

The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, P/+, N/–, P1 and a screw for earthing. A screw for P/+, N/–, and P1 of the 01800 is indicated in brackets. A screw for P/+ terminal for option connection of the 03250 and 03610 is indicated in brackets. A screw for earthing (grounding) of the 04320 or more is indicated in brackets.

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

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque reduction) in the low speed range.

CAUTION:

● 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 crimping terminals with insulation sleeve to wire the power supply and motor.

Notes on earthing

Leakage currents flow in the inverter or the EMC filter respectively. To prevent an electric shock, the inverter, input filter and motor must be earthed. (This inverter must be earthed. Earthing must conform to the requirements of national and local safety regulations and electrical codes. (JIS, NEC section 250, IEC 536 class 1 and other applicable standards)).

Use the dedicated earth terminal to earth the inverter. (Do not use the screw in the casing, chassis, etc.)

Use the thickest possible earth cable. Use the cable whose size is equal to or greater than that indicated in Tab. 3-4, and minimize the cable length. The earthing point should be as near as possible to the inverter.

Always earth the motor and inverter

● Purpose of earthing Generally, an electrical apparatus has an earth 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 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 is important to audio equipment, sensors, computers and other apparatuses that handle low-level signals or operate very fast.

● Earthing methods and earthing work As described previously, earthing 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 inverter's high frequency components from entering the malfunction prevention type earthing:

– Where possible, use independent earthing for the inverter. If independent earthing (I) is

impossible, use joint earthing (II) where the inverter is connected with the other equipment at an earthing point. Joint earthing as in (III) must be avoided as the inverter is connected with the other equipment by a common earth cable. Also a leakage current including many high frequency components flows in the earth cables of the inverter and inverter-driven motor. Therefore, they must use the independent earthing method and be separated from the earthing of equipment sensitive to the aforementioned noises. In a tall building, it will be a good policy to use the noise malfunction prevention type earthing with steel frames and carry out electric shock prevention type earthing in the independent earthing method.

– This inverter must be earthed. Earthing must conform to the requirements of national

and local safety regulations and electrical codes. (JIS, NEC section 250, IEC 536 class 1 and other applicable standards).

– Use the thickest possible earth cable. The earth cable should be of not less than the size

indicated in Tab. 3-4.

– The grounding point should be as near as possible to the inverter, and the ground wire

length should be as short as possible.

– Run the earth 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.

Total wiring length

The maximum possible length of the motor cables depends on the capacity of the inverter and the selected carrier frequency. The cables should never be longer than the maximum permissible length.

The lengths in the following table are for unshielded cables. When shielded cables are use divide the values listed in the table by 2. Note that the values are for the total wiring length – if you connect more than one motor in parallel you must add the lengths of the individual motor cables.

Note that the motor windings are subjected to significantly higher loads when the motor is operated by inverter than with normal mains operation. In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400 V class motor, the surge voltage may deteriorate the insulation. The motors must be approved for inverter operation by the manufacturer (refer also to section 3.8.5).

When the 400V class motor is driven by the inverter, consider the following measures:

● Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 "PWM frequency selection" according to wiring length.

Wiring Main circuit connection

● To suppress the surge voltage at the inverter output, connect an output filter. Please contact your Mitsubishi dealer for more details.

NOTES Especially for long-distance wiring, the inverter may be affected by a charging current

caused by the stray capacitances of the wiring, leading to a malfunction of the overcurrent protective function or fast response current limit function, or a malfunction or fault of the equipment connected on the inverter output side. If fast-response current limit malfunctions, disable this function. Refer to section 6.2.4 for details of Pr. 156 "Stall prevention operation selection".

Refer to section 6.14.1 for details of Pr. 72 "PWM frequency selection". When using the optional sine wave filter for the 01800 or more, set Pr. 72 to "25" (25kHz).

Multi-speed can be selected according to the combination of RH, RM and RL signals.

Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal to start Jog operation.

Turn on the RT signal to select second function. When the second function such as "second torque boost" and "second V/F (base frequency)" are set, turning on the RT signal selects these functions.

Turn on the MRS signal (20ms or more) to stop the inverter output. Use to shut off the inverter output when stopping the motor by electromagnetic brake.

Used to reset alarm output provided when protective function is activated. Turn on the RES signal for more than 0.1s, then turn it off. Initial setting is for reset always. By setting Pr. 75, reset can be set to enabled only at an inverter alarm occurrence. Recover about 1s after reset is cancelled.

Terminal 4 is made valid only when the AU signal is turned on. (The frequency setting signal can be set between 4 and 20mA DC.) Turning the AU signal on makes terminal 2 (voltage input) invalid.

AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as PTC input terminal, set the AU/PTC switch to PTC and assign the PTC function to the AU input terminal.

When the CS signal is left on, the inverter restarts automatically at power restoration. Note that restart setting is necessary for this operation. In the initial setting, a restart is disabled. (Refer to Pr. 57 in section 6.11.)

A determined control function is activated, if the corresponding terminal is connected to the terminal SD (sink logic). The SD terminal is isolated from the digital circuits via opto couplers. The terminal is isolated from the reference potential of the analog circuit (terminal 5). Common reference potential (0V) for 24V DC/

0.1A output (PC terminal).

When the STF and STR signals are turned on simultaneously, the stop command is given.

Switched low when the inverter output frequency is equal to or higher than the starting frequency (initial value 0.5Hz). Switched high during stop or DC injection brake operation.

The SU output supports a monitoring of frequency setting value and frequency current value. The output is switched low, once the frequency current value (output frequency of the inverter) approaches the frequency setting value (determined by the setting value signal) within a preset range of tolerance (Pr. 41). Switched high during acceleration/deceleration and at a stop.

The OL is switched low, if the output current of the inverter exceeds the current limit preset in Pr. 22 and the stall prevention is activated. If the output current of the inverter falls below the current limit preset in Pr. 22, the signal at the OL output is switched high.

The output is switched low for a temporary power failure within a range of 15ms ≤ tIPF ≤ 100ms or for under voltage.

The output is switched low once the output frequency exceeds a value preset in Pr. 42 (or 43). Otherwise the FU output is switched high.

● Use two or more parallel micro-signal contacts or twin contacts to prevent a contact faults when using contact inputs since the control circuit input signals are micro-currents.

Fig. 3-11:

Contacts

I001021E

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

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

● It is recommended to use the cables of 0.75mm² gauge for connection to the control circuit

terminals.

● If the cable gauge used is 1.25mm² or more, the front cover may be lifted when there are many cables running or the cables are run improperly, resulting in an operation panel contact fault.

● The wiring length should be 30m maximum.

Wiring of the control circuit of the 01800 or more

For wiring of the control circuit of the 01800 or more, separate away from wiring of the main circuit. Make cuts in rubber bush of the inverter side and lead wires.

3.4.3 Separate power supply for the control circuit

In an alarm condition the frequency inverter’s integrated alarm relay only remains active as long as there is a mains power supply on terminals R/L1, S/L2 and T/L3. If you want the alarm signal to remain active after the frequency inverter has been switched off a separate power supply for the control circuit is required, which should be connected as shown in the circuit diagram below. Remove the shortening jumpers from the terminal block and connect the 380–500V AC, 50/ 60Hz mains power supply to terminals R1/L11 and S1/L21. The control circuit power consumption on L11/L21 is 60VA for 00380 or less and 80VA for 00470 to 02160.

3.7 Connection of stand-alone option units

The inverter accepts a variety of stand-alone option units as required.

CAUTION:

Incorrect connection will cause inverter damage or accident. Connect and operate the

3.7.1 Magnetic contactors (MC)

option unit carefully in accordance with the corresponding option unit manual.

Inverter input side magnetic contactor (MC)

On the inverter input side, it is recommended to provide an MC for the following purposes:

● To release the inverter from the power supply when the inverter's protective function is

activated or when the drive is not functioning (e.g. emergency operation).

● To prevent any accident due to an automatic restart at restoration of power after an inverter

stop made by a power failure.

● To separate the inverter from the power supply to ensure safe maintenance and inspection

work.

If using an MC for emergency stop during motor driving, select an MC regarding the inverter input side current as JEM1038-AC-3 class rated current.

NOTE Since repeated inrush currents at power on will shorten the life of the converter circuit

(switching life is about 1,000,000 times.), frequent starts and stops of the MC must be avoided. Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter.

Electromagnetic compatibility (EMC) Wiring

3.8 Electromagnetic compatibility (EMC)

3.8.1 Leakage currents and countermeasures

Mains filters, shielded motor cables, the motor, and the inverter itself cause stationary and variable leakage currents to PE. Since its value depends on the capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following measures. Select the earth leakage breaker according to its rated sensitivity current, independent of the carrier frequency setting.

To-earth (ground) leakage currents

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

● Countermeasures

– If the carrier frequency setting is high, decrease the Pr. 72 "PWM frequency selection"

setting. Note that motor noise increases. Selecting Pr. 240 "Soft-PWM operation selection" makes the sound inoffensive.

– By using earth leakage circuit breakers designed for harmonic and surge suppression

in the inverter's own line and other line, operation can be performed with the carrier frequency kept high (with low noise).

● To-earth leakage currents

– Take caution as long wiring will increase the leakage current. Decreasing the carrier

frequency of the inverter reduces the leakage current. – Increasing the motor capacity increases the leakage current. – Shielded motor cables significantly increase the leakage current to PE (approx. double

the value generated with unshielded motor cables of the same length).

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 or more) for the 400V class small-capacity model (FR-F700-00170 or less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases.

● Countermeasures

– Use Pr. 9 "Electronic thermal O/L relay". – If the carrier frequency setting is high, decrease the Pr. 72 "PWM frequency selection"

setting. Note that motor noise increases. Selecting Pr. 240 "Soft-PWM operation selec-

tion" makes the sound inoffensive. To ensure that the motor is protected against line-to-

line leakage currents, it is recommended to use a temperature sensor (e.g. PTC element)

to directly detect motor temperature.

● Selecting a power supply circuit breaker: You can also use a circuit breaker (MCCB) to protect the power supply lines against short circuits and overloads. However, note that this does not protect the inverter (rectifiers, IGBT). Select the capacity of the circuit breaker on the basis of the cross-sectional area of the power supply lines. To calculate the required mains current trip point you need to know the power required by the inverter (refer to rated input capacity in appendix A, specifications) and the mains supply voltage. Select a circuit breaker with a trip point that is slightly higher than calculated, particularly in the case of breakers with electromagnetic tripping, since the trip characteristics are strongly influenced by the harmonics in the power supply line. The earth leakage breaker must be either a Mitsubishi earth leakage breaker (ELB, for harmonics and surges) or an ELB with breaker designed for harmonic and surge suppression that is approved for use with frequency inverters.

Note on selecting a suitable power supply ELCB

If your application requires by installation standards an RCD (residual current device) as up stream protection please select according to DIN VDE 0100-530 as following: Single phase inverter type A or B Three phase inverter only type B

Additionally, when selecting a residual current device (RCD), leakage current caused by the mains filter, the length of the shielded motor cable and the carrier frequency must be taken into consideration.

When connecting AC current using switches without a step function, brief asymmetrical loads may result in unwanted triggering of the residual current device (RCD). It is recommendable here to use a Type B residual current device (RCD) with delayed actuation or to switch on all three phases simultaneously using a main contactor.

Calculate the trip current sensitivity of the ELB as follows:

● Breaker designed for harmonic and surge suppression: IΔn ≥ 10 × (Ig1 + Ign + Igi + lg2 + lgm)

● Standard breaker: IΔn ≥ 10 × [Ig1 + Ign + Igi + 3 × (Ig2 + lgm)]

Ig1, Ig2: Leakage currents in wire path during commercial power supply operation Ign: Leakage current of inverter input side noise filter Igm: Leakage current of motor during commercial power supply operation Igi: Leakage current of inverter unit

Electromagnetic compatibility (EMC) Wiring

NOTES The frequency inverter monitors its own output for ground faults up to a frequency of 120Hz.

However, it is important to understand that this feature only protects the inverter itself. It cannot be used to provide protection against shock hazards for personnel.

In the connection earthed-neutral system, the sensitivity current is purified against an earth fault in the inverter output side. Earthing must conform to the requirements of national and local safety regulations and electrical codes. (JIS, NEC section 250, IEC 536 class 1 and other applicable standards)

When the breaker is installed on the output side of the inverter, it may be unnecessarily operated by harmonics even if the effective value is less than the rating. In this case, do not install the breaker since the eddy current and hysteresis loss will increase, leading to temperature rise.

The following models are standard breakers: BV-C1, BC-V, NVB, NV-L, NV-G2N, NV-G3NA and NV-2F earth leakage relay (except NV-ZHA), NV with AA neutral wire open-phase protection. The other models are designed for harmonic and surge suppression: NV-C/NV-S/MN series, NV30-FA, NV50-FA, BV-C2, earth leakage alarm breaker (NF-Z), NV-ZHA, NV-H.

3.8.2 Inverter-generated noises and their reduction techniques

Some noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to be insusceptible to noises, it handles low-level signals, so it requires the following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate noises. If these noises cause peripheral devices to malfunction, measures should be taken to suppress noises. These techniques differ slightly depending on noise propagation paths.

● Basic techniques

– 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 pair shielded cables for the detector connection and control signal cables.

Earth the shield.

– Earth the inverter, motor, etc. at one point.

● Techniques to reduce noises that enter and malfunction the inverter When devices that generate many noises (which use magnetic contactors, magnetic brakes, many relays, for example) are installed near the inverter and the inverter may be malfunctioned by noises, the following measures must be taken:

– Provide surge suppressors for devices that generate many noises to suppress noises. – Fit data line filters to signal cables. – Earth the shields of the detector connection and control signal cables with cable clamp

metal.

● Techniques to reduce noises that are radiated by the inverter to malfunction peripheral devices Inverter-generated noises are largely classified into:

– those radiated by the cables connected to the inverter and inverter main circuits (I/O), – those electromagnetically and electrostatically induced to the signal cables of the

peripheral devices close to the main circuit power supply,

– and those transmitted through the power supply cables.

3.8.5 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:

● Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring length. For the 400V class motor, use an insulation-enhanced motor.

– Specify the "400V class inverter-driven insulation-enhanced motor". – For the dedicated motor such as the constant-torque motor and low-vibration motor, use

the "inverter-driven, dedicated motor".

– Set Pr. 72 "PWM frequency selection" as indicated below according to the wiring length.

Wiring length

≤ 50m 50m to 100m ≥ 100m

Parameter 72 ≤ 15 (14.5kHz) ≤ 9 (9kHz) ≤ 4 (4kHz)

Tab. 3-17:

Setting of Pr. 72 according to the wiring length

● Limiting the voltage rise speed of the frequency inverter output voltage (dU/dT): If the motor requires a rise speed of 500V/µs or less you must install a filter in the output of the inverter. Please contact your Mitsubishi dealer for more details.

NOTE For details of Pr. 72 "PWM frequency selection", refer to section 6.14.

Operation Precautions for use of the inverter

4 Operation

4.1 Precautions for use of the inverter

The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items.

● Use crimping terminals with insulation sleeve to wire the power supply and motor.

● Application of power to the output terminals (U, V, W) of the inverter will damage the inverter.

Never perform such wiring.

● After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in a control box etc., take care not to allow chips and other foreign matter to enter the inverter.

● Use cables of the size to make a voltage drop 2% maximum. 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. (Refer to page 3-11 for the recommended cable sizes.)

● The overall wiring length should be within the prescribed length. Especially for long distance wiring, the fast-response current limit function may be reduced or the equipment connected to the inverter output side may malfunction or become faulty under the influence of a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 3-14.)

● Electromagnetic Compatibility Operation of the frequency inverter can cause electromagnetic interference in the input and output that can be propagated by cable (via the power input lines), by wireless radiation to nearby equipment (e.g. AM radios) or via data and signal lines. Activate the integrated EMC filter (and an additional optional filter if present) to reduce air propagated interference on the input side of the inverter. Use AC or DC reactors to reduce line propagated noise (harmonics). Use shielded motor power lines to reduce output noise (refer also to section 3.8 "Electromagnetic Compatibility").

● Do not install a power factor correction capacitor, surge suppressor or radio noise filter on the inverter output side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is installed, immediately remove it.

● Before starting wiring or other work after the inverter is operated, 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.

FR-F700 EC 4 - 1

Precautions for use of the inverter Operation

Powe r

supply

Undesirable current

● A short circuit or earth fault on the inverter output side may damage the inverter modules.

– Fully check the insulation resistance of the circuit prior to inverter operation since

repeated short circuits caused by peripheral circuit inadequacy or an earth fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter modules.

– Fully check the to-earth insulation and inter-phase insulation of the inverter output side

before power-on. Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.

● Do not use the inverter input side magnetic contactor to start/stop the inverter. Since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 1,000,000 times), frequent starts and stops of the MC must be avoided. Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter.

● Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits. Contact to the inverter I/O signal circuits or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short terminals 10E (10, respectively) and 5.

● Provide electrical and mechanical interlocks for MC1 and MC2 which are used for commercial power supply-inverter switch-over. When the wiring is incorrect or if 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.

Fig. 4-1:

Mechanical interlocks for MC1 and MC2

I001042E

● If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter's input side 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.

● Inverter input side magnetic contactor (MC) On the inverter input side, connect an MC for the following purposes (also refer to section

3.1.1):

– To release the inverter from the power supply when a fault occurs or when the drive is

not functioning (e.g. emergency stop operation). For example, MC avoids overheat or burnout of the brake resistor when heat capacity of the resistor is insufficient or brake regenerative transistor is damaged with short while connecting an optional brake resistor.

– To prevent any accident due to an automatic restart at restoration of power after an

inverter stop made by a power failure.

4 - 2

– To separate the inverter from the power supply to ensure safe maintenance and

inspection work. If using an MC for emergency stop during operation, select an MC regarding the inverter input side current as JEM1038-AC-3 class rated current.

Operation Precautions for use of the inverter

● Handling of inverter output side magnetic contactor Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter and such will activate. When an MC is provided for switching to the commercial power supply, for example, switch it ON/OFF after the inverter and motor have stopped.

● When the motor speed is unstable, due to change in the frequency setting signal caused by electromagnetic noises from the inverter, take the following measures when applying the motor speed by the analog signal:

– Do not run the signal cables and power cables (inverter I/O cables) in parallel with each

other and do not bundle them.

– Run signal cables as far away as possible from power cables (inverter I/O cables).

– Use shield cables as signal cables.

– Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

● Instructions for overload operation When performing operation of frequent start/stop of the inverter, increase/decrease in the temperature of the transistor element of the inverter may repeat due to a continuous flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing bound current, starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, increase the inverter capacity to have enough allowance for current.

● Make sure that the specifications and rating match the system requirements.
