What is the maximum number of inverters that can be connected using FL remote communication?

Up to 64 inverters can be connected when using FL remote communication. Each inverter must be assigned a unique node address between 1 and 64 using the node address switches. (Page 2)

How do I reset the inverter when a fault occurs?

The inverter can be reset using three methods: (1) Press the reset button on the operation panel, (2) Change the error reset signal setting of the FL remote communication from 0 to 1, or (3) Switch OFF the power once, then switch it ON again after the indicator turns OFF. The inverter recovers about 1 second after reset is released. (Page 24)

What cable size should I use for the main circuit wiring?

Select the recommended cable size to ensure that a voltage drop will be 2% or less. The manual provides selection examples for wiring lengths of 20m or less, with different cable sizes recommended based on inverter model and whether HIV cables, AWG, or PVC cables are used. For longer distances, use larger diameter cables. (Pages 11)

Can I install a power factor correction capacitor on the inverter output side?

No, do not install a power factor correction capacitor, surge suppressor, or capacitor type filter on the inverter output side. These devices will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of these devices are connected, immediately remove them. (Page 3)

What are the environmental specifications for operating the inverter?

The inverter must be used under the following environment: surrounding air temperature of -10°C to +50°C (non-freezing), ambient humidity of 90%RH or less (non-condensing), indoors free from corrosive gas, flammable gas, oil mist, dust and dirt, at altitudes not exceeding 1,000m above sea level, and with vibration of 5.9m/s² or less at 10 to 55Hz. (Page 4)

How should I connect the 24V external power supply to the inverter?

Connect the 24V external power supply across terminals +24 and SD. The input voltage must be 23.5 to 26.5VDC with input current of 0.7A or less. When the 24V external power supply is connected, FL-net communication can continue while the main power circuit is OFF, and the operation panel will display 'EV' flickering. (Page 15)

What is the maximum wiring length for the overall connection of motors to the inverter?

The overall wiring length should be 500m or less. For long-distance wiring exceeding 100m, the inverter may be affected by charging current caused by stray capacitances of the wiring, which can lead to malfunction of the overcurrent protective function or other equipment failures. When using automatic restart after instantaneous power failure with wiring exceeding 100m, select without frequency search. (Page 12)

What precaution must I take when connecting a brake resistor to the inverter?

When using a brake resistor whose capacity is 11K or higher, always install a thermal relay to prevent overheat and burnout of the brake resistor. The brake resistor cannot be connected to the 0.1K or 0.2K models. A sequence must be configured to turn OFF power when a fault signal is output. (Pages 5, 16)

What is the correct method for wiring the control circuit terminals?

For control circuit wiring, strip off about 10mm of the wire sheath and use blade terminals or single wires inserted directly into sockets. Use recommended wire sizes of 0.3mm² to 0.75mm², with maximum wiring length of 30m. Use shielded or twisted cables and keep them away from main and power circuits. Do not solder wires, and do not short across terminals +24 and SD. (Pages 13-14)

(2) Wiring (3) Trial run (4) Usage (5) Emergency stop (6) Maintenance, inspection and parts replacement (7) Disposal z Do not install a power factor correction capacitor or surge suppressor/capacitor type filter on the inverter output side. These devices on the inverter output side may be overheated or burn out. z The connection orientation of the output cables U, V, W to the motor affects the rotation direction of the motor. z Before starting operation, each parameter must be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions. z Any person must stay away from the equipment when the retry function is set as it will restart suddenly after trip. z 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. z 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. z The inverter must be used for three-phase induction motors. Connection of any other electrical equipment to the inverter output may damage the equipment. z Do not modify the equipment. z Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the product. z 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. z Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. Otherwise the life of the inverter decreases. z The effect of electromagnetic interference must be reduced by using a noise filter or by other means. Otherwise nearby electronic equipment may be affected. z 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. z 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. z 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. z 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. z 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. z Before running an inverter which had been stored for a long period, inspection and test operation must be performed. z For prevention of damage due to static electricity, nearby metal must be touched before touching this product to eliminate static electricity from your body.

Caution

Warning

Caution

z 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. z 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. z When any protective function is activated, appropriate corrective action must be taken, and the inverter must be reset before resuming operation. z Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. It will cause a failure. z The inverter must be treated as industrial waste. General instruction Many of the diagrams and drawings in this Instruction Manual (Basic) show the inverter without a cover or partially open for explanation. Never operate the inverter in this manner. The cover must be always reinstalled and the instruction in this Instruction Manual (Basic) must be followed when operating the inverter.

2 Installation of the inverter and instructions 2

Installation And Wiring

Note

y Up to 64 inverters can be connected when using FL remote communication. y 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. This must be noted especially when the inverter is installed in an enclosure. (Refer to page 4) y Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit to protect them from noise. (Refer to page 5) y 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. y 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, install options among the capacitor type EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, Filterpack, and EMC filter to minimize the interference. ( Refer to the Instruction Manual (Applied)). y Refer to the instruction manual of each option and peripheral devices for details of peripheral devices. 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 1MHz to 10MHz. A wire should be wound four turns at a maximum. Motor Earth (Ground)

AC power supply Use within the permissible power supply specifications of the inverter. To ensure safety, use a moulded case circuit breaker, earth leakage circuit breaker or magnetic contactor to switch power ON/OFF. 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 shorten. Reactor (FR-HAL, FR-HEL option) Reactors (option) must be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (500kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. Remove the jumpers across terminals P/+ and P1 to connect the DC reactor. 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. Install an EMC filter (ferrite core) to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a more effective result can be obtained. A wire should be wound four turns or more. Earth (Ground) To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction noise from the power line of the inverter, it is recommended to wire the earth (ground) cable by returning it to the earth (ground) terminal of the inverter.

3 Peripheral devices 2.1 Peripheral devices Check the inverter model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity. Refer to the following list and prepare appropriate peripheral devices: ∗1 ySelect an MCCB according to the power supply capacity. yInstall one MCCB per inverter. ∗2 For the use in the United States or Canada, select a UL and cUL certified fuse with Class T fuse equivalent cut-off speed or faster with the appropriate rating for branch circuit protection. Alternatively, select a UL489 molded case circuit breaker (MCCB). ∗3 Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is used for emergency stop during motor driving, the electrical durability is 25 times. When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC with class AC-3 rated current for the motor rated current. ∗4 The power factor may be slightly lower.

12 Wiring 2.3.6 Connecting the 24V external power supply FL remote communication between the master module and the inverter can be continued while the main power circuit is OFF if the 24V external power supply is connected across terminals +24 and SD. When the main circuit power supply is turned ON, the power supply changes from the 24V external power supply to the main circuit power supply. (1) Specification of the applied 24V external power supply y Input voltage 23.5 to 26.5VDC y Input current 0.7A or less (2) Operation panel display during the 24V external power supply operation y "EV" flickers. (3) Function of the 24V external power supply operation y When the main power supply is turned ON during the 24V external power supply operation, a reset is performed in the inverter, then the power supply changes to the main circuit power supply. During the reset operation in the inverter, the inverter cannot be controlled through the FL remote communication. y The operation stops when the power supply changes to the 24V external power supply from the main circuit power supply regardless of the operating status (in a stop, in running, in automatic restart after instantaneous power failure, in offline tuning, in main circuit capacitor life measurement). y All start signals (STF signal, STR signal, and on the operation panel) are invalid during the 24V external power supply operation. y Faults history and parameters can be read and parameters can be written (when the parameter write from the operation panel is enabled) using the operation panel keys. y The safety stop function is also valid during the 24V external power supply operation. When the safety stop function is active, however, "SA" is not displayed because "EV" is displayed. The "EV" display has priority over the "SA" display. y The following items can be monitored during the 24V external power supply operation: Frequency setting, output current peak value∗, converter output voltage peak value∗, cumulative energization time, actual operation time∗, cumulative power∗, and cumulative power 2∗ (monitor dedicated to the FL remote communication) ∗The monitored data is not updated after the power supply is changed from the main circuit power supply. (Refer to Chapter 5 of the Instruction Manual (Applied) for the details of each monitor.) y The valid signals when the 24V external power supply is ON are ALM, Safety alarm, Edit, NET, READY and Y95. (Other signals are OFF.) (Refer to Chapter 5 of the Instruction Manual (Applied) for the detail of each signal.) y The alarms, which have occurred when the main circuit power supply is ON, continue to be output after the power supply is changed to the 24V external power supply. Perform the inverter reset to reset the alarms. y The retry function is invalid for all alarms when the 24V external power supply is ON. y If the power supply changes from the main circuit power supply to the 24V external power supply while measuring the main circuit capacitor's life in the PU operation mode, the measurement completes after the power supply changes back to the main circuit power supply (Pr.259 = "3").

Note

y When the 24V external power supply is input while the main circuit power supply is OFF, the FL remote communication is enabled, but the inverter operation is disabled. y Inrush current higher than the value described in (1) may flow at a power-ON. Confirm that the power supply and other devices are not affected by the inrush current and the voltage drop caused by it. y When the wiring length between the external power supply and the inverter is long, the voltage often drops. Select the appropriate wiring size and length to keep the voltage in the rated input voltage range. y In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the power supply. The increase of the current causes voltage to drop further. When connecting different inverters to different power supplies, use the inverters after confirming that the input voltage of each inverter is within the rated input voltage range. y "E.SAF" may appear when the start-up time of the 24V power supply is too long in the 24V external power supply operation.

Precautions For Use Of The Inverter

Precautions For Use Of The Inverter

The FR-E700 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 8 for the recommended wire sizes. (5) The overall wiring length should be 500m or less. Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the secondary 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 9) (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, install the FR-BIF optional capacitor type filter (for use in the input side only) or FR-BSF01 common mode filter to minimize interference. (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 are connected, immediately remove them. (8) For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor. Before wiring or inspecting inside the inverter, wait 10 minutes or longer after turning OFF the power supply, then confirm that the voltage across the main circuit terminals P/+ and N/- of the inverter is 30VDC or less using a tester, etc. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous. (9) If "EV" is displayed on the operation panel, turn off the 24V external power supply before wiring and inspection. (10) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules. y 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. y 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. (11) 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. Turn ON/OFF the inverter start controlling terminals (STF, STR) to run/stop the inverter. ( Refer to the Instruction Manual (Applied))

Precautions For Use Of The Inverter

(12) Across P/+ and PR terminals, connect only an external regenerative brake discharging resistor. Do not connect a mechanical brake. The brake resistor cannot be connected to the 0.1K or 0.2K. Leave terminals P/+ and PR open. Also, never short between these terminals. (13) 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. (15) 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. (16) Inverter input side magnetic contactor (MC) On the inverter input side, connect a MC for the following purposes. (Refer to page 3 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. (17) 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. (18) Instructions for overload operation When performing operation of frequent start/stop of the inverter, rise/fall in the temperature of the transistor element of the inverter will repeat due to a repeated 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 current at locked condition, starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in capacity). (19) Make sure that the specifications and rating match the system requirements. (14) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for bypass operation. When the wiring is incorrect and if there is a bypass operation circuit as shown 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.

Failsafe Of The System Which Uses The Inverter

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. (1) Interlock method which uses the inverter status output signals By providing interlocks, inverter fault can be detected. For the interlocks, use different status output signals of the inverter (virtual terminals of the FL remote communication) in combinations shown below. (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, 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. 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. No. Interlock Method Check Method Used Signals Refer to Page 1) Inverter protective function operation Operation check of an alarm contact Circuit error detection by negative logic Fault output signal (ALM signal) Refer to Chapter 4 of the Instruction Manual (Applied). 2) Inverter running status Check of the reset release signal Reset release signal (READY signal) Refer to Chapter 4 of the Instruction Manual (Applied). 3) Inverter running status Logic check of the start signal and running signal Start signal (STF signal, STR signal) Running signal (RUN signal) Refer to Chapter 4 of the Instruction Manual (Applied). 4) Inverter running status Logic check of the start signal and output current Start signal (STF signal, STR signal) Output current detection signal (Y12 signal) Refer to Chapter 4 of the Instruction Manual (Applied).

Troubleshooting

When a fault occurs in the inverter, the inverter trips and the display on the operation panel automatically changes to one of the following fault or 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. z Retention of fault output signal...When the magnetic contactor (MC) provided on the input side of the inverter is opened when a fault occurs, the inverter's control power will be lost and the fault output will not be held. z Fault or alarm indication ..........When a fault or alarm occurs, the operation panel display automatically switches to the fault or alarm indication. z Resetting method ....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter cannot restart. z When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation. Not doing so may lead to the inverter fault and damage. Inverter fault or alarm indications are roughly categorized as below. (1) Error message A message regarding operational fault and setting fault by the operation panel is displayed. The inverter does not trip. (2) Warning The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a fault. (3) Alarm The inverter does not trip. (4) Fault When a fault occurs, the inverter trips and a fault signal is output. The ALM signal is also output. 6.1 Reset method of protective function (1) 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 released.

Remarks

y For the details of fault displays and other malfunctions, also refer to the Instruction Manual (Applied). y Past eight faults can be displayed using the setting dial. Operation 1: ...... Using the operation panel, press to reset the inverter. (This may only be performed when a fault occurs.) Operation 2: ......

Precautions For Maintenance And Inspection

The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors. zPrecautions for maintenance and inspection 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. If "EV" is displayed on the operation panel, turn off the 24V external power supply before inspection. 7.1 Inspection items ∗1 It is recommended to install a device to monitor voltage for checking the power supply voltage to the inverter. ∗2 One to two years of periodic inspection cycle is recommended. However, it differs according to the installation environment. Consult us for periodic inspection.

Specifications

8.1 Rating z Three-phase 200V power supply z Three-phase 400V power supply ∗1 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor. ∗2 The rated output capacity indicated assumes that the output voltage is 230V for three-phase 200V class and 440V for three-phase 400V class. ∗3 The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for the inverter and motor to return to or below the temperatures under 100% load. ∗4 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 that of the power supply. ∗5 The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz 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. (Option brake resistor cannot be used for 0.1K and 0.2K.) ∗6 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables). ∗7 Setting 2kHz or more in Pr. 72 PWM frequency selection to perform low acoustic noise operation in the surrounding air temperature exceeding 40°C, the rated output current is the value in parenthesis. ∗8 y Connect DC power supply to terminal P/+ and N/-. Connect the plus side of the power supply to terminal P/+ and minus side to terminal N/-. y Since the voltage between P/+ and N/- may increase due to the regeneration energy from the motor and exceeds 415V temporarily, select the DC power supply which can withstand the voltage/energy during regeneration. If using the power supply which can not withstand voltage/energy during regeneration, insert diodes in series for reverse current prevention. y Although the FR-E700 series has the built-in inrush current limit circuit, select the DC power supply considering the inrush current at powering ON as the inrush current four times of the rated inverter flows at powering ON. y Since the power supply capacity depends on the output impedance of the power, select the power supply capacity which has enough allowance according to the AC power supply system capacity.

General Precaution

The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power off, wait for more than 10 minutes, and check for residual voltage between terminal P/+ and N/- with a meter etc. to avoid a hazard of electrical shock.

Installation

The below types of inverter have been approved as products for use in enclosure and approval tests were conducted under the following conditions. Design the enclosure so that the surrounding air temperature, humidity and ambience of the inverter will satisfy the specifications (Refer to page 4). Wiring protection Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the National Electrical Code for the U.S. or the Canadian Electrical Code for Canada and any additional codes. As specified on page 36, UL Class T fuses or any faster acting fuse with the appropriate rating or Listed UL 489 Molded Case Circuit Breaker (MCCB) must be employed.

400V class

Suitable For Use in A Circuit Capable of Delivering Not More Than 100 kA rms Symmetrical Amperes, 528 V Maximum.

Wiring

For wiring the input (R/L1, S/L2, T/L3) and output (U, V, W) terminals of the inverter, use the UL Listed copper, stranded wires (rated at 75°C) and round crimping terminals. Crimp the crimping terminals with the crimping tool recommended by the terminal maker.

Motor overload protection

When using the electronic thermal relay function as motor overload protection, set the rated motor current to Pr. 9 "Electronic thermal O/L relay". (Refer to page 36) Appendix 2 Instructions for UL and cUL Note ⋅Protective function by electronic thermal relay function is reset by inverter power reset and reset signal input. Avoid unnecessary reset and power-OFF. ⋅When multiple motors are operated by a single inverter, protection cannot be provided by the electronic thermal relay function. Install an external thermal relay to each motor. ⋅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. ⋅A special motor cannot be protected by the electronic thermal relay function. Use the external thermal relay. ⋅Electronic thermal relay may not function when 5% or less of inverter rated current is set to electronic thermal relay setting.
