This Instruction Manual (Basic) provides handling information and precautions for use of the equipment. Please forward this Instruction Manual (Basic) to the end user.

This section is specifically about safety matters

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

WARNING

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.

CAUTION

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

WARNING

• While power is ON or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.

• Do not run the inverter with the front cover or 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 inverter circuits and get an electric shock.

• Before wiring, inspection or switching EMC filter ON/OFF connector, 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, inspection or switching EMC filter ON/OFF connector 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 inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter 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 inverter 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 replace the cooling fan while power is ON. It is dangerous to replace 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 (Pr. 259 Main circuit capacitor life measuring = "1"), 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.

• IPM motor is a synchronous motor with high-performance magnets embedded in the rotor. Motor terminals hold highvoltage while the motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. When the motor is driven by the load in applications such as fan and blower, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.

2. Fire Prevention

CAUTION

• Inverter must be installed on a nonflammable wall without holes (so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

• If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current could cause a fire.

• Do not connect a resistor directly to the DC terminals P/+ and N/

-. Doing so could cause a fire.

3. Injury Prevention

CAUTION

• 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 inverter since the inverter will be extremely hot. Doing so can cause burns.

4. Additional Instructions

Also the following points must be noted to prevent an accidental failure, injury, electric shock, etc.

(1) Transportation and installation

CAUTION

• The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries.

• Do not stack the boxes containing inverters higher than the number recommended.

• The product must be installed to the position where withstands the weight of the product 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.

• The inverter mounting orientation must be correct.

• Foreign conductive objects must be prevented from entering the

inverter. That includes screws and metal fragments or other flammable substance such as oil.

• As the inverter is a precision instrument, do not drop or subject it to impact.

• The inverter must be used under the following environment: Otherwise the inverter may be damaged.

Surrounding air temperature

Ambient humidity 90% RH or less (non-condensing) Storage temperature -20°C to +65°C

Atmosphere

Environment

Altitude, vibration

*1 Temperature applicable for a short time, e.g. in transit. *2 2.9m/s

or less for the 185K or higher.

-10°C to +50°C (non-freezing)

Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

Maximum 1000m above sea level for standard operation. 5.9m/s

to 55Hz (directions of X, Y, Z axes)

*2 or less at 10

A-1

(2) Wiring

• Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. These devices on the inverter output side may be overheated or burn out.

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

• IPM motor terminals (U, V, W) hold high-voltage while the IPM motor is running even after the power is turned OFF. Before wiring, the IPM motor must be confirmed to be stopped. Otherwise you may get an electric shock.

• Never connect an IPM motor to the commercial power supply. Applying the commercial power supply to input terminals (U,V, W) of an IPM motor will burn the IPM motor. The IPM motor must be connected with the output terminals (U, V, W) of the inverter.

(3) Test operation and adjustment

• Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.

(4) Operation

• The IPM motor capacity must be same with the inverter capacity. (The 0.75K inverter can be used with a one-rank lower MM-EF motor.)

• Do not use multiple IPM motors with one inverter.

• Any person must stay away from the equipment when the retry

function is set as it will restart suddenly after trip.

• Since pressing 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 inverter fault. Resetting inverter alarm with the start signal ON restarts the motor suddenly.

• Do not use an IPM motor in an application where a motor is driven by its load and runs at a speed higher than the maximum motor speed.

• A dedicated IPM motor must be used under IPM motor control. Do not use a synchronous motor, induction motor, or synchronous induction motor under IPM motor control.

• The inverter must be used for three-phase induction motors or the dedicated IPM motor. Connection of any other electrical equipment to the inverter 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 inverter.

CAUTION

WARNING

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.

• The effect of electromagnetic interference must be reduced by using a noise 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 inverter may heat/ damage the power factor correction capacitor and generator.

• When driving a 400V class motor by the inverter, the motor must be an insulation-enhanced motor or measures must be taken to suppress surge voltage. Surge voltage attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

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

• Before running an inverter which had been stored for a long period, inspection and test operation must be performed.

• For prevention of damage due to static electricity, nearby metal must be touched before touching this product to eliminate static electricity from your body.

• Do not connect an IPM motor under the general-purpose motor control settings (initial settings). Do not use a general-purpose motor under the IPM motor control settings. Doing so will cause a failure.

• In the system with an IPM motor, the inverter power must be turned ON before closing the contacts of the contactor at the output side.

(5) Emergency stop

• A safety backup such as an emergency brake must be provided to prevent hazardous condition to the machine and equipment in case of inverter failure.

• When the breaker on the inverter input side trips, the wiring must be checked for fault (short circuit), and internal parts of the inverter 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 inverter must be reset before resuming operation.

CAUTION

A-2

(6) 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.

(7) Disposing of the inverter

CAUTION

• The inverter must be treated as industrial waste.

2 INSTALLATION AND WIRING

Three-phase AC power supply

Use within the permissible power supply specifications of the inverter.

(Refer to page 150)

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 page 4)

Magnetic contactor(MC)

Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shortened.

(Refer to page 4)

Reactor (FR-HAL, FR-HEL)

Install reactors to suppress harmonics and to improve the power factor. An AC reactor (FR-HAL) (option) is required when installing the inverter 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 55K or lower, remove the jumpers across terminals P/+ and P1 to connect to the DC reactor.

(Refer to Chapter 3 of the Instruction Manual (Applied) .)

Inverter (FR-F700P)

The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. Especially when mounting the inverter inside an enclosure, take cautions of the surrounding air temperature. (Refer to page 8) 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.

EMC filter (ferrite core) (FR-BSF01, FR-BLF)

Install an EMC filter (ferrite core) to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 0.5MHz to 5MHz. A wire should be wound four turns at a maximum.

(Refer to Chapter 3 of the Instruction Manual (Applied) .)

Contactor Example) No-fuse switch (DSN type)

Install a contactor in an application where the IPM motor is driven by the load even at power-OFF of the inverter. Do not open or close the contactor while the inverter is running (outputting).

Dedicated IPM motor (MM-EFS, MM-EF)

Use the specified motor. IPM motors cannot be driven by the commercial power supply.

(Refer to page 163 and 164)

INSTALLATION AND WIRING

CAUTION

· Do not install a power factor correction capacitor, surge suppressor or capacitor type 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 are connected, immediately remove them.

· Electromagnetic wave interference The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to minimize interference.

(Refer to Chapter 2 of the Instruction Manual (Applied).)

· Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.

· An IPM motor cannot be driven by the commercial power supply.

CAUTION

· The power supply cables must be connected to R/L1, S/L2, T/L3. (Phase sequence needs not to be matched.) Never connect the power cable to the U, V, W of the inverter. Doing so will damage the inverter.

· Connect the motor to U, V, W. At this time, turning ON the forward rotation switch (signal) rotates the motor in the counterclockwise direction when viewed from the motor shaft.

· When wiring the inverter main circuit conductor of the 250K or higher, tighten a nut from the right side of the conductor. When wiring two wires, place wires on both sides of the conductor. (Refer to the drawing below.) For wiring, use bolts (nuts) provided with the inverter.

• Handling of the wiring cover (FR-F720P-18.5K, 22K, FR-F740P-22K, 30K) For the hook of the wiring cover, cut off the necessary parts using a pair of long-nose pliers etc.

CAUTION

Cut off the same number of lugs as wires. If parts where no wire is put through has been cut off (10mm or more), protective structure (JEM1030) becomes an open type (IP00).

Wiring

(1) Cable size and other specifications of the main circuit terminals and the earthing terminal

Select the recommended cable size to ensure that a voltage drop will be 2% or less. If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. The following table indicates a selection example for the wiring length of 20m.

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 tighten too loosely can cause a short circuit or malfunction. A screw that has been tighten 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.

Wiring

(2) Notes on earthing (grounding)

• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards) A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.

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

• Use the thickest possible

and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.

To be compliant with the EU Directive (Low Voltage Directive), earth (ground) the inverter according to

the instructions on page 171.

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.

Use to reset fault output provided when fault occurs. Turn ON the RES signal for more than 0.1s, then turn it OFF. In the initial status, reset is set always-enabled. By setting Pr.75, reset can be set enabled only at fault occurrence. Inverter recovers about 1s after the reset is released.

Terminal 4 is valid only when the AU signal is turned ON. (The frequency setting signal can be set between 0 and 20mADC.) 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.

When the CS signal is left power restoration. Note that restart setting is necessary for this operation. In the initial setting, a restart is disabled.

2.4.6 Changing the control logic

The input signals are set to sink logic (SINK) when shipped from the factory. To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to the other position. (The output signals may be used in either the sink or source logic independently of the jumper connector position.)

1)Loosen the two installation screws in both ends of the control circuit terminal block. (These screws cannot be removed.) Pull down the terminal block from behind the control circuit terminals.

2)Change the jumper connector set to the sink logic (SINK) on the rear panel of the control circuit terminal block to source logic (SOURCE).

Jumper connector

3)Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it with the mounting screws.

INSTALLATION AND WIRING

CAUTION

1. Make sure that the control circuit connector is fitted correctly.

2. While power is on, never disconnect the control circuit terminal block.

4)Sink logic and source logic ⋅ In sink logic, a signal switches ON when a current flows from the corresponding signal input terminal.

Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.

⋅ In source logic, a signal switches ON when a current flows into the corresponding signal input terminal.

Terminal PC is common to the contact input signals. Terminal SE is common to the open collector output signals.

Control circuit terminal

Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Do not earth(ground) these terminals. Avoid connecting the terminal SD and 5 and the terminal SE and 5. Terminal SD is a common terminal for the contact input terminals (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) and frequency output signal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler. Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal AM. It should be protected from external noise using a shielded or twisted cable. Terminal SE is a common terminal for the open collector output terminal (RUN, SU, OL, IPF, FU). The contact input circuit is isolated from the internal control circuit by photocoupler.

(3) Signal inputs by contactless switches

The contacted input terminals of the inverter (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled using a transistor instead of a contacted switch as shown on the right.

(4) Wiring instructions

1) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals. If the cable gauge used is 1.25mm

the cables are run improperly, resulting in an operation panel contact fault.

2) The maximum wiring length should be 30m (200m for terminal FM).

3) 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.

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

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

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

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

Refer to page 4 for selection.)

(

1)To release the inverter from the power supply when the fault occurs or when the drive is not functioning (e.g. emergency stop operation). To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure

3)To separate the inverter from the power supply to ensure safe maintenance and inspection work The inverter's input side MC is used for the above purpose, select class JEM1038-AC3MC for the inverter input side current when making an emergency stop during normal operation.

REMARKS

Since repeated inrush current at power ON will shorten the life of the converter circuit (switching life is 100 million times (about 500,000 times for the 200V class 37K or higher)), frequent starts/stops must be avoided. Turn ON/OFF the inverter start controlling terminals (STF, STR) to run/stop the inverter.

(2) Handling of the inverter output side magnetic contactor

Switch the magnetic contactor between the inverter and general-purpose 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 using a magnetic contactor to switch to a commercial power supply while using a

general-purpose motor, it is recommended to use the bypass operation Pr. 135 to Pr. 139. (Refer to Chapter 4 of the Instruction Manual (Applied)).

CAUTION

IPM motor is a synchronous motor with high-performance magnets embedded in the rotor. Motor terminals hold high-voltage while the motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. When the motor is driven by the load in applications such as fan and blower, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.

INSTALLATION AND WIRING

Precautions for use of the inverter

2.7 Precautions for use of the inverter

The FR-F700P 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.

(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.

(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform

such wiring.

(3) 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 an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

(4) Use cables of the size to make a voltage drop 2% or less.

If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. Refer to page 15 for the recommended cable sizes.

(5) When using a general-purpose motor, the overall wiring length should be 500m or less.

When using an IPM motor, the overall wiring length should be 100m or less.

Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the 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 17)

(6) Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to minimize interference. (Refer to page 10)

(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type 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.

(8) For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor.

When accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched OFF, and then make sure that the voltage across the main circuit terminals P/+ and N/- of the inverter is not more than 30VDC using a tester, etc.

(9) A short circuit or earth (ground) 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 (ground) fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter modules.

· Fully check the to-earth (ground) insulation and phase to 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.

(10) 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. (Refer to page 9)

(11) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.

Application of a voltage higher than the permissible voltage 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 and 5.

(12) When driving a general-purpose motor, provide

electrical and mechanical interlocks for MC1 and MC2 which are used for bypass operation.

When the wiring is incorrect or if there is an electronic bypass circuit as shown on the right, the inverter will be damaged when the power supply is connected to the inverter U, V, W terminals due to arcs generated at the time of switch-over or chattering caused by a sequence error.

Precautions for use of the inverter

(13) 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.

(14) Inverter input side magnetic contactor (MC)

On the inverter input side, connect a MC for the following purposes. (Refer to page 4 for selection.)

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.

2)To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure

3)To separate the inverter from the power supply to ensure safe maintenance and inspection work.

The inverter's input side MC is used for the above purpose, select class JEM1038-AC3 MC for the inverter input side current when making an emergency stop during normal operation.

(15) 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 MC is provided for switching to the commercial power supply, for example, switch it ON/OFF after the inverter and motor have stopped. IPM motor is a synchronous motor with high-performance magnets embedded in the rotor. Motor terminals hold highvoltage while the motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. When the motor is driven by the load in applications such as fan and blower, a lowvoltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.

(16) Countermeasures against inverter-generated EMI

If electromagnetic noise generated from the inverter causes frequency setting signal to fluctuate and motor rotation speed to be unstable when changing motor speed with analog signal, the following countermeasures are effective.

· 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).

(17) Instructions for overload operation

When performing an 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 motor may not start. A counter action for this is to raise the permissible current level by increasing the inverter capacity (up to 2 ranks) when using a general-purpose motor, and by increasing the inverter and IPM motor capacities when using an IPM motor.

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

Failsafe of the system which uses the

inverter

2.8 Failsafe of the system which uses the inverter

When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter

fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,

provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the

inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,

without using the inverter, is enabled even if the inverter fails.

(2) Backup method outside the inverter

Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure

status of the inverter itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter

fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output

even if an inverter fault occurs.

Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the

backup system such as checking up as below according to the level of importance of the system.

1) Start signal and actual operation check

Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to

the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor

current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the

start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is

recommended to check the three-phase current when using the current detector.

2) Command speed and actual operation check

Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command

and detected speed of the speed detector.

3 DRIVING THE IPM MOTOR

Highly efficient motor control and highly accurate motor speed control can be performed by using the inverter with an IPM motor.

The motor speed is detected by the output voltage and current of the inverter. It does not require a speed detector such as an encoder. The inverter drives the IPM motor with the least required current when a load is applied in order to achieve the highest motor efficiency.

POINT

The following conditions must be met to perform IPM motor control.

· For the motor model, dedicated IPM motor (MM-EFS model or MM-EF model) must be used. The motor capacity must be equivalent to the inverter capacity. (The 0.75K inverter can be used with the 0.4kW

· Single-motor operation (one motor run by one inverter) must be performed.

· The overall wiring length with the motor must be 100m or less.

* IPM parameter initialization is performed by setting Pr. 998 IPM parameter initialization or by selecting (IPM parameter initialization) on the

operation panel. To change to the IPM motor control, perform IPM parameter initialization at first. If parameter initialization is performed after setting other parameters, some of those parameters will be initialized too. (Refer to page 43 for the parameters that are initialized.)

REMARKS

· "Er1" appears if IPM parameter initialization is performed while Pr.72 = "25."

· To use a 0.4kW MM-EF, set Pr.80 Motor capacity = "0.4" before setting IPM parameter initialization.

CAUTION

· For the setting range of a speed command under dedicated IPM motor (MM-EFS 1500r/min specification, MM-EF 1800r/min specification) controls, refer to the output frequency range in Chapter 8.2 Common specifications (Refer to page 152).

· The selectable carrier frequencies under IPM motor control are 2k, 6k, 10k, and 14kHz.

· Constant-speed operation cannot be performed in the low-speed range lower than 150r/min (MM-EFS 1500r/min specification) or 180r/min (MM-EF 1800r/min specification). Generally, speed control can be performed in the range that satisfies the ratio, 1:10.

· During IPM motor control, the RUN signal is output about 100ms after turning ON the start command (STF, STR). The delay is due to the magnetic pole detection.

· The following operations and controls are disabled during IPM motor control: adjustable 5 points V/F, bypass sequence, energy saving operation, Optimum excitation control, and speed smoothing.

· The option surge voltage suppression filter (FR-ASF-H/FR-BMF-H) and sine wave filter (MT-BSL/BSC) cannot be used under IPM motor control, so do not connect them.

· When parameter copy is performed from a FR-F700P series inverter, which is set to use MM-EFS under IPM motor control, check that IPM motor control is selected on the operation panel (P.RUN is lit) after the copy. When parameters are copied to a FR-F700P series inverter, which is not compatible with MM-EFS, Simple magnetic flux vector control is selected instead of IPM motor control.

Remarks

5.5.1 Energy saving operation (setting "4")

· When "4" is set in Pr. 60, the inverter performs the energy saving operation.

· In the energy saving operation, the inverter automatically controls the output voltage to minimize the inverter output voltage during a constant operation.

REMARKS

· For applications a large load torque is applied to or machines repeat frequent acceleration/deceleration, an energy saving effect is not expected.

5.5.2 Optimum excitation control (setting "9")

· When "9" is set in Pr. 60, the inverter performs the Optimum excitation control.

· The Optimum excitation control is a control method which controls excitation current to improve the motor efficiency to maximum and determines output voltage as an energy saving method.

REMARKS

· When the motor capacity is too small as compared to the inverter capacity or two or more motors are connected to one inverter, the energy saving effect is not expected.

CAUTION

· When the energy saving operation and Optimum excitation control are selected, deceleration time may be longer than the

setting value. Since overvoltage alarm tends to occur as compared to the constant-torque load characteristics, set a longer deceleration time.

· The energy saving operation and Optimum excitation control are available only under V/F control.

When a value other than "9999" is set in Pr. 80 Motor capacity, the energy saving operation and Optimum excitation control are not available.

(For Simple magnetic flux vector control, refer to Chapter 4 of the Instruction Manual (Applied).)
