IB(NA)-0600411ENG-C(1502)MEE Printed in Japan MODEL FR-F700P INSTRUCTION MANUAL (BASIC) MODEL CODE 1A2-P39 Specifications subject to change without notice. INSTRUCTION MANUAL (BASIC) HEAD OFFICE: TOKYO BUILDING 2-7-3, MARUNOUCHI, CHIYODA-KU, TOKYO 100-8310, JAPAN C 6 To obtain the Instruction Manual (Applied) If you are going to utilize functions and performance, refer to the Instruction Manual (Applied) [IB-0600412ENG]. The Instruction Manual (Applied) is separately available from where you purchased the inverter or your Mitsubishi sales representative. The PDF version of this manual is also available for download at "Mitsubishi Electric FA site," the Mitsubishi Electric FA network service on the world wide web (URL: http://www.MitsubishiElectric.co.jp/fa/) 7 8 This Instruction Manual (Basic) provides handling information and precautions for use of the equipment. Please forward this Instruction Manual (Basic) to the end user. WARNING Incorrect handling may cause hazardous conditions, resulting in death or severe injury. CAUTION Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage. CAUTION level may even lead to a serious consequence The according to conditions. Both instruction levels must be followed because these are important to personal safety. 1.Electric Shock Prevention WARNING While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the 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. Daily and periodic inspections must be performed as instructed in the Instruction Manual. If the product is used without receiving any inspection, it may cause a burst, break, or 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. Environment 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". Surrounding air temperature Ambient humidity Storage temperature Atmosphere Altitude, vibration -10°C to +50°C (non-freezing) 90% RH or less (non-condensing) -20°C to +65°C *1 Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt) Maximum 1000m above sea level for standard operation. 5.9m/s2 *2 or less at 10 to 55Hz (directions of X, Y, Z axes) *1 Temperature applicable for a short time, e.g. in transit. *2 2.9m/s2 or less for the 185K or higher. If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed before packaging the product. A-1 (2) Wiring CAUTION 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 CAUTION 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 WARNING 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 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. Static electricity in your body must be discharged before you touch the product. Otherwise the product may be damaged. 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 CAUTION 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. (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. General instructions 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.

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. CAUTION Make sure that the control circuit connector is fitted correctly. While power is on, never disconnect the control circuit terminal block. 22 Wiring 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.

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 the pulse train output terminal (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. External signal input using transistor +24V STF, etc Inverter SD (4) Wiring instructions It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals. If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or the cables are run improperly, resulting in an operation panel contact fault. The maximum wiring length should be 30m (200m for terminal FM). When using contact inputs, use two or more parallel micro-signal contacts or twin contacts to prevent a contact faults since the control circuit input signals are micro-currents. Micro signal contacts Twin contacts To suppress EMI, use shielded or twisted cables for the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields to the common terminal of the connected control circuit terminal. When connecting external power supply to the terminal PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth (ground) the shield to the enclosure, etc. Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc. 24 Wiring Wiring of the control circuit of the 75K or higher For wiring of the control circuit of the 75K or higher, separate away from wiring of the main circuit. Make cuts in rubber bush of the inverter side and lead wires. <Wiring> Rubber bush (view from the inside) Make cuts along the lines inside with a cutter knife and such. 2.4.8 Mounting the operation panel (FR-DU07) or the parameter unit (FR-PU07) on the enclosure surface Parameter unit connection cable (FR-CB2)(option) Parameter unit (FR-PU07) Operation panel(FR-DU07) (option) STF FWD PU Operation panel connection connector (FR-ADP)(option) CAUTION Do not connect the cable to a LAN port of a personal computer, to a fax modem socket, or to a telephone connector.

(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). 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 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. REMARKS Since repeated inrush current at power ON will shorten the life of the converter circuit (switching life is 1,000,000 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.

At this time, remove jumpers across terminals R/L1 and R1/L11, and S/L2 and S1/ L21. (Refer to page 17 for removal of the jumper.) A1 MC Start/Stop Start C1 As shown on the left, always use the start signal To the (ON or OFF of STF (STR) signal) to make a start motor RA RA STF/STR SD RA (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 electronic bypass function 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. 36 Precautions for use of the inverter 2.7 Precautions for use of the inverter The FR-F700P series is a highly reliable product, but using incorrect peripheral circuits or incorrect operation/handling methods 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 appropriate size to make a voltage drop of 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 14 for the recommended cable sizes. (5) The total wiring length should be within the prescribed length. Especially for long distance wiring, the fast-response current limit function may decrease, or the equipment connected to the output side may malfunction. This is caused by a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 16) (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) (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 no 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 a 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 (For the 200V class 37K or higher, switching life is about 500,000)), 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 when it 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. MC1 Power supply Interlock R/L1 U IM S/L2 V MC2 T/L3 W Undesirable current Inverter 37 2 INSTALLATION AND WIRING (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 installed, immediately remove it. 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 an 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). 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. If using an MC for emergency stop during operation, select an MC regarding the inverter input side current as JEM1038AC-3 class rated current. (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. 38 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. (1) 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 1) Inverter protective function operation Operation check of an alarm contact Circuit error detection by negative logic Fault output signal ALM signal 2) Inverter running status Operation ready signal checks Operation ready signal (RY signal) 3) Inverter running status Logic check of the start signal and running signal 4) Inverter running status Logic check of the start signal and output current Start signal (STF signal, STR signal) Running signal (RUN signal) Start signal (STF signal, STR signal) Output current detection signal Y12 signal Refer to Page Refer to Chapter 4 of the Instruction Manual (Applied) Refer to Chapter 4 of the Instruction Manual (Applied) Refer to Chapter 4 of the Instruction Manual (Applied) Refer to Chapter 4 of the Instruction Manual (Applied) (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.

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, a dedicated IPM motor (MM-EFS model, MM-THE4 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 MM-EF.) · Single-motor operation (one motor run by one inverter) must be performed. · The overall wiring length with the motor must be within the specified value. (Refer to page 16) 3.1 Setting procedure of IPM motor control IPM <IPM> · This inverter is set for a general-purpose motor in the initial setting. Follow the following procedure to change the setting for the IPM motor control. Perform IPM parameter initialization by selecting the parameter setting mode (IPM) on the operation panel.* (Refer to page 41) Set "1" or "12" in (IPM parameter initialization) to select IPM motor control. Refer to page 41 for the setting method. Setting value "1": MM-EF Setting value "12": MM-EFS, MM-THE4 P.RUN on the operation panel (FR-DU07) is lit when IPM motor control is set. Set parameters such as the acceleration/deceleration time and multi-speed setting. Set parameters such as the acceleration/deceleration time and multispeed setting as required. Set the operation command. (Refer to page 77) Select the start command and speed command. Test run * 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 42 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. · IPM motor control can also be selected with Pr. 80 Motor capacity and Pr. 998 IPM parameter initialization. (Refer to page 42) CAUTION · For the setting range of a speed command under dedicated IPM motor (MM-EFS/MM-THE4 1500r/min specification, MM-EF 1800r/min specification) controls, refer to the output frequency range in Chapter 8.2 Common specifications (Refer to page 151). · The selectable carrier frequencies under IPM motor control are 2k, 6k, 10k, and 14kHz. (Only 2k and 6kHz are selectable for 75K or higher.) · Constant-speed operation cannot be performed in the low-speed range lower than 150r/min (MM-EFS, MM-THE4 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 an FR-F700P series inverter, which is set to use MM-EFS or MM-THE4 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 an FR-F700P series inverter, which is not compatible with MM-EFS or MM-THE4, Simple magnetic flux vector control is selected instead of IPM motor control. 40 Setting procedure of IPM motor control <IPM> (1) IPM motor control setting by selecting the parameter setting mode on the operation panel ( ) POINT · The parameters required to drive an IPM motor are automatically changed as a batch.

Unless reset, therefore, the inverter cannot restart. (Refer to page 115.) 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 (FR-DU07) and parameter unit (FRPU04/FR-PU07) 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. You can also output an alarm signal by making parameter setting. (4) Fault When a fault occurs, the inverter trips and a fault signal is output. REMARKS · Past eight faults can be displayed using the setting dial. (Refer to page 131 for the operation.) The inverter can be reset by performing any of the following operations. Note that the internal accumulated heat value of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter. Inverter recovers about 1s after the reset is released. Operation 1:...... Using the operation panel, press to reset the inverter. (This may only be performed when a fault occurs.

(2) Replacement procedure of the cooling fan when using a heatsink protrusion attachment (FR-A7CN) When replacing a cooling fan, remove a top cover of the heatsink protrusion attachment and perform replacement. After replacing the cooling fan, replace the top cover in the original position. Top cover Inverter PRECAUTIONS FOR MAINTENANCE AND INSPECTION * The number of cooling fans differs according to the inverter capacity. 7 147 Inspection item (3) Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the adverse effects of ripple currents, etc. The replacement intervals greatly vary with the surrounding air temperature and operating conditions. When the inverter is operated in air-conditioned, normal environment conditions, replace the capacitors about every 10 years. The appearance criteria for inspection are as follows: 1) Case: Check the side and bottom faces for expansion 2) Sealing plate: Check for remarkable warp and extreme crack. 3) Check for external crack, discoloration, fluid leakage, etc. Judge that the capacitor has reached its life when the measured capacitance of the capacitor reduced below 80% of the rating. Refer to page 144 to perform the life check of the main circuit capacitor. (4) Relays To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times (switching life). (5) Fuse inside the inverter (185K or higher) A fuse is used inside the inverter. Surrounding air temperature and operating condition affect the life of fuses. When the inverter is used in a normal air-conditioned environment, replace its fuse after about 10 years. 7.1.7 Inverter replacement The inverter can be replaced with the control circuit wiring kept connected. Before replacement, remove the wiring cover of the inverter. 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) 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. CAUTION Before starting inverter replacement, switch power OFF, wait for at least 10 minutes, and then check the voltage with a tester and such to ensure safety. 148 Rating 8 SPECIFICATIONS 8.1 Rating 200V class Type FR-F720P-K Rated current (A)*3 0.75 1.5 0.75 1.6 4.2 (3.6) 1.5 2.2 3.7 5.5 7.5 11 15 18.5 22 30 37 45 2.7 3.7 5.8 8.8 11.8 17.1 22.1 27 32 43 53 65 7.0 9.6 15.2 23 31 45 58 70.5 85 114 140 170 (6.0) (8.2) (13) (20) (26) (38) (49) (60) (72) (97) (119) (145) 120% for 60s, 150% for 3s (inverse-time characteristics) Three-phase 200 to 240V Overload current rating*4 Rated voltage*5 Rated input AC voltage/ frequency Permissible AC voltage fluctuation Permissible frequency fluctuation Power supply system capacity (kVA)*6 Without DC reactor With DC reactor 2.2 3.7 5.5 7.5 11 *2 *3 *4 *5 *6 *7 *8 18.5 22 30 37 45 55 75 90 55 75 90 81 110 132 212 288 346 (180) (244) (294) 110 110 165 432 (367) Three-phase 200 to 220V 50Hz, 200 to 240V 60Hz 170 to 242V 50Hz, 170 to 264V 60Hz ±5% 2.1 4.0 4.8 8.0 11.5 16 20 27 32 41 52 65 79 99 — — — 1.2 2.6 3.3 5.0 8.1 10 16 19 24 31 41 50 61 74 110 132 165 70 70 Protective structure (JEM 1030)*8 Enclosed type (IP20) *7 Cooling system Self-cooling Approx. mass (kg) 1.8 2.2 3.5 3.5 3.5 6.5 6.5 *1 15 Open type (IP00) Forced air cooling 7.8 13 13 14 23 35 35 67 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor. To use a dedicated IPM motor, refer to page 162、164. The rated output capacity indicated assumes that the output voltage is 220V. When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency automatically decreases if the inverter output current exceeds the value in parentheses of the rated current. This may cause the motor noise to increase. 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. 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 that of the power supply. The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables). When the hook of the inverter front cover is cut off for installation of the plug-in option, protective structure of the inverter changes to an open type (IP00).

It is not the percentage to the rated motor current. When you set the electronic thermal relay function dedicated to the Mitsubishi constant-torque motor, this characteristic curve applies to operation at 6Hz or higher. CAUTION The internal accumulated heat value of the electronic thermal relay function is reset by inverter power reset and reset signal input. Avoid unnecessary reset and power-OFF. When using multiple motors with one inverter, or using a multi-pole motor or a specialized motor, provide an external thermal relay (OCR) between the inverter and motor. And for the setting of the thermal relay, add the line-to line leakage current to the current value on the motor rating plate. For low-speed operation where the cooling capability of the motor reduces, it is recommended to use a thermal protector or thermistor-incorporated 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. Motor over temperature sensing is not provided by the drive. The use of FR-F700P with an IPM motor is not certified by the UL nor cUL. 172 MEMO 173 REVISIONS *The manual number is given on the bottom left of the back cover.
