CAUTION

Observe the protective notes and measures! Please observe the following items in order to ensure proper use of the FR-D700 SC inverter.

앫 When mounting, installing and using the FR-D700 SC inverter, observe the standards and directives applicable in your country. 앫

The national rules and regulations apply to the installation, use and periodic technical inspection of the FR-D700 SC, in particular: – Machinery Directive 98/37/EC (from 29.12.2009 Machinery Directive 2006/42/EC), – EMC Directive 2004/108/EC, – Provision and Use of Work Equipment Directive 89/655/EC, – Low-Voltage Directive 2006/95/EC, – Work safety regulations/safety rules.

앫 Manufacturers and owners of the machine on which a FR-D700 SC inverter is used are responsible for obtaining and observing

all applicable safety regulations and rules.

앫 It is imperative that the notices, in particular the test notices of the manuals be observed. 앫 The tests must be carried out by specialised personnel or specially qualified and authorised personnel and must be recorded

and documented to ensure that the tests can be reconstructed and retraced at any time by third parties.

3.1 Electric Shock Prevention

앫

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

앫

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

앫

Even if power is OFF, do not remove the front cover except for wiring or periodic inspection. You may access the charged inverter circuits and get an electric shock.

앫 Before starting wiring or inspection, check to make sure that the operation panel indicator is OFF, 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.

앫 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) Use a neutral-point earthed (grounded) power supply for 400 V class inverter in compliance with EN standard.

앫 Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work. 앫 Always install the inverter before wiring. Otherwise you may get an electric shock or be injured. 앫 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 (Additional instructions on the use of a residual current device are contained on page 27.)

앫 Perform setting dial and key operations with dry hands to prevent an electric shock. Otherwise you may get an electric shock. 앫 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock. 앫 Do not replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on. 앫 Do not touch the printed circuit board or handle the cables with wet hands. You may get an electric shock. 앫 When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1 s at powering off. Never touch

the motor terminal, etc. right after powering off to prevent an electric shock.

shock.

3.2 Fire Prevention

앫 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 flammable material can cause a fire.

앫 If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could cause a fire. 앫 When using a brake resistor, make up a sequence that will turn off power when an alarm signal is output. Otherwise, the brake

resistor may excessively overheat due to damage of the brake transistor and such, causing a fire.

앫 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.

3.3 Injury Prevention

앫 Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur. 앫 Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur. 앫 Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur. 앫 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.

4.1 Transportation and Installation

앫 Transport the product using the correct method that corresponds to the weight. Failure to observe this could lead to injuries. 앫 Do not stack the inverter boxes higher than the number recommended. 앫

Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the instruction manual.

앫 Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns. 앫 When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail. 앫 Do not stand or rest heavy objects on the product. 앫 Check the inverter mounting orientation is correct. 앫 Prevent other conductive bodies such as screws and metal fragments or other flammable substance such as oil from entering

the inverter.

앫 As the inverter is a precision instrument, do not drop or subject it to impact. 앫 Use the inverter under the following environmental conditions. Otherwise, the inverter may be damaged.

햲

Temperature applicable for a short time, e.g. in transit.

4.2 Wiring

앫 Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not

approved from Mitsubishi Electric.

앫 The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence

(U, V, W) is maintained.

4.3 Test Operation and Adjustment

앫

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

4.4 Operation

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

앫 Since pressing 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).

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

앫 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.

앫 Do not modify the equipment. 앫 Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the inverter.

앫

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.

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

inverter decreases.

앫 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.

앫 Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators. 앫 When a 400 V class motor is inverter-driven, please use an insulation-enhanced motor or measures taken to suppress surge

voltages. Surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.

앫 When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter

returns to the initial value.

앫

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

앫

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.

앫 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

앫

from your body.

앫 If you are installing the inverter to drive a three-phase device while you are contracted for lighting and power service, consult

your electric power supplier.

4.5 Emergency Stop

앫

Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

앫

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.

앫

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.

4.6 Maintenance, Inspection and Parts Replacement

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

It is recommended to make the following checks periodically:

앫 Check for loose screws in the terminal block. Retighten any loose screws. 앫 Check for dust accumulation on the inverter. Clean the heat sink and the cooling fan of the inverter. 앫 Check for unusual noise generated by the inverter. Retighten installation screw. 앫 Check for the operation condition. Keep the operation condition of inverter as written in the manual.

4.7 Disposal of the Inverter

앫 Disposal of unusable or irreparable devices should always occur in accordance with the applicable country-specific waste-

disposal regulations (e.g. European Waste Code 16 02 14).

Note that the motor windings in three-phase AC motors are subject to far more stress when operated via frequency inverters than with mains operation. The motor must have been approved by the manufacturer for operation on a frequency inverter.

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. When the 400 V class motor is driven by the inverter, consider the following measures: 앫 Use a "400 V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection according to

wiring length.

Wiring Length

 50 m 50 m–100 m  100 m

Carrier frequency  14.5 kHz  8 kHz  2 kHz

앫 Limiting the voltage rise speed of the frequency inverter output voltage (dV/dT):

If the motor requires a rise speed of 500 V/μs or less you must install a filter in the output of the inverter. Please contact your Mitsubishi Electric dealer for more details.

CAUTION

앫

Especially for long-distance wiring (particularly when employing shielded motor cables), 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 stall prevention function or a malfunction or fault of the equipment connected

on the inverter output side. When the fast-response current limit function malfunctions, make the function invalid. When stall prevention function misoperates, increase the stall level. (For Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection, refer to the Instruction Manual.)

앫 For details of Pr. 72 PWM frequency selection, refer to the Instruction Manual. 앫 When using the automatic restart after instantaneous power failure function with wiring length exceeding below, select

4.4.4 Wiring Instructions

앫 Terminals PC, 5, and SE are all common terminals (0 V) for I/O signals and are isolated from each other. Avoid connecting the

terminal PC and 5 and the terminal SE and 5 (ground). Terminal PC is a common terminal for the contact input terminals (STF, STR, RH, RM and RL).

Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits

앫

(including the 230 V relay sequence circuit). Use two or more parallel micro-signal contacts or twin

앫

contacts to prevent a contact faults when using contact inputs since the control circuit input signals are micro-currents.

앫

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

앫 Always apply a voltage to the alarm output terminals (A, B, C)

via a relay coil, lamp, etc. In no way must a voltage be shortcircuited by these relay contacts.

앫 It is recommended to use the cables of 0.3mm² to 0.75mm² gauge for connection to the control circuit terminals.

The wiring length should be 30 m maximum.

앫 The level of the control signals can be switched over between positive (SOURCE) and negative (SINK) logic. The input signals are

5 PRECAUTIONS FOR USE OF THE INVERTER

The FR-D700 SC 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.

앫 Use crimping terminals with insulation sleeve to wire the power supply and motor. 앫 Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring. 앫 After wiring, wire offcuts must not be left in the inverter.

앫 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 7 for the recommended cable size.

앫 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 8)

앫 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. Install an 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. For EMC correct installation refer to the Manual for Frequency Inverters and EMC.

앫 Do not install a power factor correction capacitor, varistor or arrester on the inverter output side. This will cause the inverter to

trip or the capacitor, varistor, or arrester to be damaged. If any of the above devices is installed, immediately remove it.

앫 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.

앫 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 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.

앫 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.

앫

Across P/+ and PR terminals, connect only an external regenerative brake discharge resistor. Do not connect a mechanical brake. The brake resistor can not be connected to the FR-D720S-008SC and 014SC. Leave terminals P/+ and PR open. Also, never short between P/+ and PR.

supply

앫 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 10-5.

앫

Provide electrical and mechanical interlocks for MC1 and MC2 which are used for bypass operation. When the wiring is incorrect or if there is a bypass circuit as shown on the right, 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.

If the machine must not be restarted when power is restored after a power

앫

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.

앫 Inverter input side magnetic contactor (MC)

On the inverter input side, connect a MC for the following purposes. (Refer to the Instruction Manual.) – 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 – 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.

앫 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.

앫 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.

앫 Make sure that the specifications and rating match the system requirements. 앫 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 shielded cables as signal cables. – Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

6 FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER

System failure

Controller

Inverter

Sensor

(speed, temperature,

air volume, etc.)

To the alarm detection sensor

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 Electric 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.

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.

Interlock Method which uses the Inverter Status Output Signals

By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be detected.

Interlock Method Check Method Used Signals Refer to

Inverter protective function operation

Inverter runnning status

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, even if the interlock is provided using the inverter fault output signal, start signal and RUN signal output, there is a case where a fault output 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. 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.

8 TROUBLESHOOTING

The frequency inverter FR-D700 SC has a multitude of protective functions which protect the drive and the inverter from damage in case of a fault. When a fault occurs in the inverter, the protective function is activated bringing the inverter to an alarm stop and the PU display automatically changes to any of the following fault (alarm) indications. If the fault does not correspond to any of the following faults or if you have any other problem, please contact your sales representative.

앫

Retention of fault output signal..... When the magnetic contactor (MC) provided on the input side of the inverter is opened at

the activation of the protective function, the inverter's control power will be lost and the alarm output will not be held.

앫

Fault or alarm display.........................When a fault or alarm occurs, the operation panel display automatically switches to the fault

or alarm indication.

앫

Resetting method ...............................When a protective function of the inverter is activated, the power output of the inverter is

blocked (motor is coasting). The inverter cannot start up again unless an automatic restart has been configured or the inverter is reset. Please observe carefully the warnings contained below in the configuration of an automatic restart or the execution of a reset.

앫 If protective functions were activated (i. e. the inverter switched off with an error message) follow the instructions for error correction

provided in the manual for the inverter. Especially in the case of short circuits or earth contacts in the inverter output and mains overvoltages the cause of the fault must be determined prior to switching on again as a recurrence of such faults at short intervals can lead to premature aging of components or even the complete breakdown of the device. After the cause of the fault has been found and corrected the inverter can be reset and operations continue.

Inverter fault or alarm indications are roughly divided as below. 앫 Error Message

A message regarding operational fault and setting fault by the operation panel and parameter unit (FR-PU04/FR-PU07) is displayed The inverter does not shut off output.

앫 Warning

The inverter does not shut off output even when a warning is displayed. However, failure to take appropriate measures will lead to a major fault.

앫 Alarm

The inverter does not shut off output. You can also output an alarm signal by making parameter setting.

앫 Fault

When the protective function is activated, the inverter output is shut off and an fault signal is output.

NOTES

앫 For the details of fault displays and other malfunctions, also refer to the Instruction Manual. 앫 Past eight faults can be displayed using the setting dial.

CAUTION

8.1 Reset Method of Protective Function

Resetting the Inverter

The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter. Inverter recovers about 1s after reset is cancelled.

Three different methods can be used to reset an inverter. 앫 Using the operation panel, press the STOP/RESET key to reset the inverter.

(This may only be performed when a fault occurs.)

앫 Switch OFF the power once, then switch it ON again after the indicator

of the operation panel turns OFF.

앫 Turn ON the reset signal (RES) for more than 0.1 s. (If the RES signal is kept ON,

"Err." appears (flickers) to indicate that the inverter is in a reset status.)

OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter fault with the start signal ON restarts the motor suddenly. This may cause injury.

9 MAINTENANCE AND INSPECTION

CAUTION

9.1 Daily Inspection

Followings are the daily checking points during operation:

앫 Rotation speed of motor 앫 Environmental condition of the inverter drive 앫 Activation of cooling system 앫 Extraordinary vibration or airborne noise 앫 Over heating or discoloration

For detailed checking operation please refer to the Instruction manual of FR-D700 SC.

9.2 Periodic Inspection

It is recommended to make the following checks periodically:

앫 Check for loose screws in the terminal block. Retighten any loose screws. 앫 Check for dust accumulation on the inverter. Clean the heat sink and the cooling fan of the inverter. 앫 Check for unusual noise generated from the inverter. Retighten installation screw. 앫

Check for the operation condition. Keep the operation condition of inverter as written in the Inverter FR-D700 SC Instruction Manual.

앫 For detailed maintenance operation please refer to the Instruction manual of FR-D700 SC.

앫 To avoid an electric shock hazard, insert the magnetic contactor (MC) between AC power supply and FR-D700 SC.

Open the contact of MC and keep away from drive for discharging time (10 minutes) before performing any work on the drive. And verify that the voltage on the bus capacitors has discharged before Measure the DC bus voltage at the P/+ and N/– terminals or test points (refer to page 6 "Main circuit terminal specifications" for locations). The voltage must be zero.

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

9.3 Checking and Testing of Restart Prevention

To avoid systematic faults, a test even for faulty demands of the safety function has to be performed in order to check the correct function of the restart prevention.

This test shall be carried out at system installation, any software changes, parameterization changes, and/or at least once per year. For detailed checking procedure refer to the "Transistorized Inverter FR-D700 SC Safety stop function Instruction Manual".

Any misuse of safety function could lead to personal injury or death, property damage, or economic loss. To ensure that the system complies fully with requirement of safety, make a system-level risk assessment and adequate verification for systematic failure.

The applied motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard motor.

The rated output capacity indicated assumes that the output voltage is 230 V/440 V (200 V class/400 V class).

The % value of the overload current rating indi cated is the ratio of the overload current to the inverter’s rated output current (ambient temperature of 50 °C for 400 V class). For repeated duty, allow time for the inverter and motor to return to or below the temperatures under 100 % load.

The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However, the pulse voltage value of the inverter output side voltage remains unchanged at about 2

The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60 Hz in the shortest time and is not a continuous regenerative torque. When the motor is decelerated from the frequency higher than the base frequency, the average deceleration torque will reduce. Since the inverter does not contain a brake resistor, use the optional brake resistor when regenerative energy is large. A brake unit (FR-BU2) may also be used.

The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).

When operating the inverter with ambient temperature of 40 °C maximum, the rated output current is the value in parentheses.

that of the power supply.

We have self-confirmed our inverters as products compliant to the Low Voltage Directive (conforming standard EN 61800-5-1) and placed the CE mark on the inverters.

Outline of Instructions

앫

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) Type B with delayed actuation or to switch on all three phases simultaneously using a main contactor.

앫 If you do not use a residual current operated protectice device, provide double or reinfo

other equipment, or put a transformer between the main power supply and inverter.

앫

Do not use a residual current operated protective device (RCD) as an electric shock protector without connecting the equipment to the earth. Connect the equipment to the earth securely.

앫 Wire the earth terminal independently. (Do not connect two or more cables to one terminal.) 앫 Use the cable sizes on page 7 under the following conditions.

– Ambient temperature: 40 °C maximum – If conditions are different from above, select appropriate wire according to EN 60204 ANNEX C TABLE 5.

앫

Use a tinned (plating should not include zinc) crimping terminal to connect the earth cable. When tightening the screw, be careful not to damage the threads.

앫 For use as a product compliant with the Low Voltage Directive, use PVC cable whose size is indicated on page 8. 앫 Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard. 앫 Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the power

supply), overvoltage category III (usable with the earthed-neutral system power supply, 400 V class only) specified in IEC664.

앫 To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher. 앫 To use the inverter (IP20) outside of an enclosure in the enviroment of pollution degree 2, fix a fan cover with the fan cover

fixing srews enclosed.

rced insulation between the inverter and

앫 On the input and output of the inverter, use cables of the type and size set forth in EN 60204 Appendix C. 앫 The operating capacity of the relay outputs (terminal symbols A, B, C) should be 30 V DC, 0.3 A. (Relay outputs are basically

isolated from the inverter internal circuit.)

앫 Control circuit terminals on page 5 are safely isolated from the main circuit.

Motor Overload Protection

The frequency inverters FR-D700 SC are equipped with a UL certified internal electronic thermal relay function. When using the electronic thermal relay as motor overload protection, set the rated motor current to Pr. 9

Electronic thermal O/L relay

Electronic thermal relay function operation characteristic

This function detects the overload (overheat) of the motor, stops the operation of the inverter's output transistor, and stops the output.

When using the Mitsubishi Electric constant-torque motor set "1" or any of "13", "50" or "53" in Pr. 71. This provides a 100 % continuous torque characteristic in the low-speed range. Set the rated current of the motor in Pr. 9.

When 50 % of the inverter rated output current (current value) is set in Pr. 9.

The % value denotes the percentage to the inverter rated output current. It is not the percentage to the motor rated current.

When you set the electronic thermal relay function dedicated to the Mitsubishi Electric constant-torque motor, this characteristic curve applies to operation at 6 Hz or higher.

APPENDIX

CAUTION

앫

Protective function by electronic thermal relay function is reset by inverter power reset and reset signal input. Avoid unnecessary reset and power-OFF.

앫 Install an external thermal relay (OCR) between the inverter and a motor when operating several motors by one inverter, or

when using a multi-pole motor or special motor. In this case, set 0A to the electronic thermal O/L relay setting of the inverter. For the external thermal relay, determine the setting value in consideration of the current indicated on the motor's rating plate and the line-to-line leakage current. Self-cooling ability of a motor is reduced at low speed operation. Use a motor with a builtin thermal protector.

앫 When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics

of the electronic thermal relay function will be deteriorated. In this case, use an external thermal relay.

앫 A special motor cannot be protected by the electronic thermal relay function. Use an external thermal relay.
