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).

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.
