a - 1 thank you for choosing the mitsubishi transistorized inverter. this instruction manual gives handling information and precautions for use of this equipment. incorrect handling might cause an unexpected fault. before using the inverter, please read this manual carefully to use the equipment to its optimum. please forward this manual to the end user. this instruction manual uses the international system of units (si). the measuring units in the yard and pound system are indicated in parentheses as reference values. 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 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 manual, the safety instruction levels are classified into "warning" and "caution". assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury. assumes that incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause physical damage only. note that even the caution level may lead to a serious consequence according to conditions. please follow the instructions of both levels because they are important to personnel safety. warning caution a - 2 safety instructions 1. electric shock prevention warning ! while power is on or when the inverter is running, do not open the front cover. you may get an electric shock. ! 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. ! 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. ! before starting wiring or inspection, switch power off, wait for more than 10 minutes, and check for residual voltage with a meter (refer to chapter 2 for further details) etc. ! earth the inverter. ! any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work. ! always install the inverter before wiring. otherwise, you may get an electric shock or be injured. ! operate the switches and potentiometers with dry hands to prevent 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 change the cooling fan while power is on. it is dangerous to change the cooling fan while power is on. 2. fire prevention caution ! mount the inverter and brake resistor on an incombustible surface. installing the inverter directly on or near a combustible surface could lead to a fire. ! if the inverter has become faulty, switch off the inverter power. a continuous flow of large current could cause a fire. ! when a brake resistor is used, use an alarm signal to switch power off. otherwise, the brake resistor will overheat abnormally due a brake transistor or other fault, resulting in a fire. ! do not connect a resistor directly to the dc terminals p( + ), n( ? ). this could cause a fire. a - 3 3. injury prevention caution ! apply only the voltage specified in the instruction manual to each terminal to prevent damage etc. ! ensure that the cables are connected to the correct terminals. otherwise, damage etc. may occur. ! always make sure that polarity is correct to prevent damage etc. ! while power is on and for some time after power-off, do not touch the inverter or brake resistor as they are hot and you may get burnt. 4. additional instructions also note the following points to prevent an accidental failure, injury, electric shock, etc. ( 1 ) transportation and installation caution ! when carrying products, use correct lifting gear to prevent injury. ! do not stack the inverter boxes higher than the number recommended. ! ensure that installation position and material can withstand the weight of the inverter. install according to the information in the instruction manual. ! do not operate if the inverter is damaged or has parts missing. ! do not hold the inverter by the front cover or operation panel; it may fall off. ! do not stand or rest heavy objects on the inverter. ! check the inverter mounting orientation is correct. ! prevent screws, wire fragments or other conductive bodies or oil or other flammable substance from entering the inverter. ! do not drop the inverter, or subject it to impact. ! use the inverter under the following environmental conditions: ambient temperature constant torque : -10 c to +50 c (14 f to 122 f) (non-freezing) ambient humidity 90%rh or less (non-condensing) storage temperature -20 c to +65 c * (-4 f to 149 f) ambience indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt) environment altitude, vibration maximum 1000m (3280.80 feet) above sea level for standard operation. after that derate by 3% for every extra 500m (1640.40 feet) up to 2500m (8202.00 feet) (91%). 5.9 m/s 2 or less (conforming to jis c 0911) *temperatures applicable for a short time, e.g. in transit. a - 4 ( 2 ) wiring caution ! do not fit capacitive equipment such as a power factor correction capacitor, radio noise filter or surge suppressor to the output of the inverter. ! the connection orientation of the output cables u, v, w to the motor will affect the direction of rotation of the motor. ( 3 ) trial run caution ! check all parameters, and ensure that the machine will not be damaged by a sudden start-up. ( 4 ) operation warning ! when you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop. ! the [stop] key is valid only when the appropriate function setting has been made. prepare an emergency stop switch separately. ! make sure that the start signal is off before resetting the inverter alarm. a failure to do so may restart the motor suddenly. ! the load used should be a three-phase induction motor only. connection of any other electrical equipment to the inverter output may damage the equipment. ! do not modify the equipment. caution ! the electronic overcurrent protection does not guarantee protection of the motor from overheating. ! do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter. ! use a noise filter to reduce the effect of electromagnetic interference. otherwise nearby electronic equipment may be affected. ! take measures to suppress harmonics. otherwise power harmonics from the inverter may heat/damage the power capacitor and generator. a - 5 caution ! when a 400v class motor is inverter-driven, it should be insulation-enhanced or surge voltages suppressed. surge voltages attributale to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. ! when parameter clear or all clear is performed, each parameter returns to the factory setting. re-set the required parameters before starting operation. ! the inverter can be easily set for high-speed operation. before changing its setting, fully examine the performances of the motor and machine. ! in addition to the inverter's holding function, install a holding device to ensure safety. ! before running an inverter which had been stored for a long period, always perform inspection and test operation. ( 5 ) emergency stop caution ! provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails. ( 6 ) maintenance, inspection and parts replacement caution ! do not carry out a megger (insulation resistance) test on the control circuit of the inverter. ( 7 ) disposing of the inverter caution ! treat as industrial waste.

(a selection example for the wiring length of 20m (65.62 feet) is shown on page 21.) 5) for long distance wiring, the overcurrent protection may be activated improperly or the devices connected to the output side may misoperate or become faulty under the influence of a charging current due to the stray capacitance of the wiring. therefore, the maximum overall wiring length should be as indicated in the following table. if the wiring length exceeds the value, it is recommended to set "1" in pr. 156 to make the fast-response current limit function invalid. (when two or more motors are connected to the inverter, the total wiring length should be within the indicated value.) inverter capacity 0.1k 0.2k 0.4k 0.75k 1.5k 2.2k 3.7k or more 100v, 200v class 200 (656.16) 200 (656.16) 300 (984.24 ) 500 (1640.40) 500 (1640.40) 500 (1640.40) 500 (1640.40) non-low acoustic noise mode 400v class ?? 200 (656.16) 200 (656.16) 300 (984.24) 500 (1640.40) 500 (1640.40) 100v, 200v class 30 (98.42) 100 (328.08) 200 (656.16) 300 (984.24) 500 (1640.40) 500 (1640.40) 500 (1640.40) low acoustic noise mode 400v class ?? 30 (98.42) 100 (328.08) 200 (656.16) 300 (984.24) 500 (1640.40) (unit: m (feet)) overall wiring length (3.7k or more) 500m (1640.40 feet) maximum 300m (984.24 feet) 300m (984.24 feet) 3 00m (984.24 feet)+300m (984.24 feet)=600m ( 1968.48 feet ) installation and wiring 19 6) connect only the recommended optional brake resistor between the terminals p - pr (+ - pr). keep terminals p-pr (+ - pr) of 0.1k or 0.2k open. these terminals must not be shorted. 0.1k and 0.2k do not accept the brake resistor. keep terminals p-pr (+ - pr) open. also, never short these terminals. 7) electromagnetic wave interference the input/output (main circuit) of the inverter includes harmonic components, which may interfere with the communication devices (such as am radios) used near the inverter. in this case, install the fr-bif optional radio noise filter (for use in the input side only) or fr-bsf01 or fr-blf line noise filter to minimize interference. 8) do not install a power capacitor, surge suppressor or radio noise filter (fr-bif option) in the output side of the inverter. 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 them. (when using the fr-bif radio noise filter with a single-phase power supply, connect it to the input side of the inverter after isolating the t phase securely.) 9) when rewiring after operation, make sure that the power lamp has gone off, and when more than 10 minutes has elapsed after power-off, check with a meter etc. that the voltage is zero. after that, start rewiring work. for some time after power-off, there is a dangerous voltage in the capacitor. notes on grounding " leaka g e currents flow in the inverter. to p revent an electric shock, the inverter and motor must be grounded.

" " " " countermeasures the harmonic current generated from the inverter to the power supply differs according to various conditions such as the wiring impedance, whether a power factor improving reactor is used or not, and output frequency and output current on load side. for the output frequency and output current, the adequate method is to obtain them under rated load at the maximum operating frequency. note: a power factor improving capacitor and surge suppressor on the inverter's output side may overheat or be damaged due to the harmonics of the inverter output. also, when an overcurrent flows in the inverter, the overcurrent protection is activated. hence, when the motor is driven by the inverter, do not install a capacitor or surge suppressor on the inverter's output side. to improve the power factor, insert a power factor improving reactor in the inverter's input or dc circuit. for details, refer to the fr-a500/e500 series technical information nfb im power factor improving ac reactor inverter power factor improving dc reactor motor do not insert power factor improvin g capacito r installation and wiring 35 2.3.2 inverter-generated noise and reduction techniques some noises enter the inverter causing it to incorrectly operate, and others are radiated by the inverter causing misoperation of peripheral devices. though the inverter is designed to be insusceptible to noise, it handles low-level signals, so it requires the following basic measures to be taken. also, since the inverter chops the output at high carrier frequencies, it could generate noise. if these noises cause peripheral devices to misoperate, measures should be taken to suppress noise. the measures differ slightly depending on noise propagation paths. 1) basic measures ! do not run the power cables (i/o cables) and signal cables of the inverter in parallel with each other and do not bundle them. ! use twisted shield cables for the detector connecting and control signal cables and connect the sheathes of the shield cables to terminal sd. ! ground the inverter, motor, etc. at one point. 2) measures against noise which enters and causes misoperation of the inverter when devices which generate noise (devices which use magnetic contactors, magnetic brakes, many relays, for example) are installed near the inverter, the inverter may misoperate due to noise. the following measures must be taken: ! provide surge suppressors for devices that generate noise to suppress noise. ! fit data line filters (refer to page 38) to signal cables. ! ground the shields of the detector connection and control signal cables with cable clamp metal. 2 installation and wiring 36 3) measures against noises which are radiated by the inverter causing misoperation of peripheral devices. inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter main circuit (i/o), those electromagnetically and electrostatically inducted to the signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables. inverter-generated noise air-propagated noise %%% path 3) %%% path 2) %%% path 1) %%% path 4), 5) %%% path 6) %%% path 8 ) %%% path 7 ) magnetic induc- tion noise static induction noise cable propaga- ted noise noise directly radiated by inverter noise radiated by power cables noise radiated by motor cables noise propagated through power cables leakage noise from ground cable due to leakage current instrument receiver inve- rter im sensor power supply motor telephone sensor 7) 2) 1) 3) 4) 5) 7) 2) 6) 3) 8) installation and wiring 37 noise path measures 1), 2), 3) when devices which handle low-level signals and are susceptible to misoperation due to noise (such as instruments, receivers and sensors) are installed near the inverter and their signal cables are contained in the same panel as the inverter or are run near the inverter, the devices may be misoperated by air-propagated noise and the following measures must be taken: (1) install easily affected devices as far away as possible from the inverter. (2) run easily affected signal cables as far away as possible from the inverter. (3) do not run the signal cables and power cables (inverter i/o cables) in parallel with each other and do not bundle them. (4) insert line noise filters onto i/o and radio noise filters into inputs to suppress cable-radiated noises. (5) use shielded cables for signal cables and power cables and run them in individual metal conduits to further reduce effects. 4), 5), 6) when the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises may be propagated to the signal cables causing misoperation of the devices and the following measures must be taken: (1) install easily affected devices as far away as possible from the inverter. (2) run easily affected signal cables as far away as possible from the inverter. (3) do not run the signal cables and power cables (inverter i/o cables) in parallel with each other and do not bundle them. (4) use shielded cables for signal cables and power cables and run them in individual metal conduits to further reduce effects. 7) when the power supplies of the peripheral devices are connected to the power supply of the inverter within the same line, inverter-generated noise may flow back through the power supply cables causing misoperation of the devices and the following measures must be taken: (1) install the radio noise filter (fr-bif) to the power cables (input cables) of the inverter. (2) install the line noise filter (fr-blf, fr-bsf01) to the power cables (i/o cables) of the inverter. 8) when a closed loop circuit is formed by connecting the peripheral device wiring to the inverter, leakage current may flow through the ground cable of the inverter causing misoperation of the device. in such a case, disconnection of the ground cable of the device may cause the device to operate properly. 2 installation and wiring 38 " " " " data line filter noise entry can be prevented by providing a data line filter for the detector or other cable.

(separation of 30cm (11.81 inches) reduces noise to 1/2 to 1/3.) by fitting the fr-bsf01 or blf on the inverter output side, induction noise to the signal cables can be reduced. differences between noise terminal voltages at different carrier frequencies 0 20 40 60 80 100 120 0.1 1 10 noise fre q uenc y ( mhz ) noise terminal voltage (db) conditions average terminal voltage 0db=1 v 120db=1v carrier frequency 10khz carrier frequency 1khz noise induced to signal cables by inverter output cables 5cm line-to-line distance d (cm) 20 40 60 80 100 10 0 20 30 40 50 induction voltage (db) d(cm) motor measuring instrument terminal inverter fr-blf fr-bsf01 (4t) conditions inverter: fr-e520-3.7k-na motor: fr-jr 4p 3.7kw (5hp) output frequency: 30hz noise form: normal mode parallel cable twisted pair cable coaxial cable * noise terminal voltage: represents the magnitude of noise propagated from the inverter to the power supply.

( 1 ) to-ground leakage currents leakage currents may flow not only into the inverter's own line but also into the other lines through the ground cable, etc. these leakage currents may operate earth leakage circuit breakers and earth leakage relays unnecessarily. " " " " countermeasures ! if the carrier frequency setting is high, decrease the carrier frequency (pr. 72) of the inverter. note that motor noise increases. selection of soft-pwm (pr. 240) will make it unoffending. ! by using earth leakage circuit breakers designed for harmonic and surge suppression (e.g. mitsubishi's progressive super series) in the inverter's own line and other line, operation can be performed with the carrier frequency kept high (with low noise). " " " " to-ground leakage current ! note that a long wiring length will increase leakage currents. decrease the carrier frequency of the inverter to reduce leakage currents. ! higher motor capacity leads to larger leakage currents. the leakage currents of the 400v class are higher than those of the 200v class. ( 2 ) line-to-line leakage currents harmonics of leakage currents flowing in static capacities between the inverter output cables may operate the external thermal relay unnecessarily. when the wiring length is long (50m (164.04 feet) or more) for the 400v class models, the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases. inverter power suppl y im thermal relay line static capacitances nfb line-to-line leakage current path motor 2 installation and wiring 40 " " " " countermeasures ! use the electronic overcurrent protection of the inverter. ! decrease the carrier frequency. note that motor noise increases. selection of soft-pwm will make it unoffending. to ensure that the motor is protected not to be influenced by line-to-line leakage currents, we recommend the protection method which uses a temperature sensor to directly detect motor temperature. 2.3.4 inverter-driven 400v class motor in the pwm type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. especially for a 400v class motor, the surge voltage may deteriorate the insulation. when the 400v class motor is driven by the inverter, consider the following measures: " " " " measures it is recommended to take either of the following measures: (1) rectifying the motor insulation for the 400v class motor, use an insulation-rectified motor. specifically, 1) specify the "400v class inverter-driven, insulation-rectified motor". 2) for the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven, dedicated motor".

( 1 ) emc directive 1) our view of transistorized inverters for the emc directive a transistorized inverter is a component designed for installation in a control box and for use with the other equipment to control the equipment/device. therefore, we understand that the emc directive does not apply directly to transistorized inverters. for this reason, we do not place the ce mark on the transistorized inverters. (the ce mark is placed on inverters in accordance with the low voltage directive.) the european power drive manufacturers' organization (cemep) also holds this point of view. 2) compliance we understand that the transistorized inverters are not covered directly by the emc directive. however, the emc directive applies to machines/equipment into which transistorized inverters have been incorporated, and these machines and equipment must carry the ce marks. hence, we prepared the technical information "emc installation guidelines" (information number bcn-a21041- 202) so that machines and equipment incorporating transistorized inverters may conform to the emc directive more easily. 3) outline of installation method install an inverter using the following methods: * use the inverter with an european standard-compliant noise filter. * for wiring between the inverter and motor, use shielded cables or run them in a metal piping and ground the cables on the inverter and motor sides with the shortest possible distance. * insert a line noise filter and ferrite core into the power and control lines as required. full information including the european standard-compliant noise filter specifications are written in the technical information "emc installation guidelines" (bcn-a21041-202). please contact your sales representative. installation and wiring 47 ( 2 ) low voltage directive 1) our view of transistorized inverters for the low voltage directive transistorized inverters are covered by the low voltage directive (standard to comply with: din vde0160 (200v class), en50178 (400v class, 100v class)). 2) compliance we have self-confirmed our inverters as products compliant to the low voltage directive and place the ce mark on the inverters. 3) outline of instructions * in the 400v class inverters, the rated input voltage range is three-phase, 380v to 415v, 50hz/60hz. * connect the equipment to the earth securely. do not use an earth leak age circuit breaker as an electric shock protector without connecting the equipment to the earth. * wire the earth terminal independently. (do not connect two or more cables to one terminal.) * the wire size on pages 19 and 21 are shown for following conditions ! ambient temp : 40 c (104 f) maximum ! wire installation : on wall without ducts or conduits if conditions are different from above, select appropriate wire according to en 60204 annex c table 5. * use the no-fuse breaker and magnetic contactor which conform to the en or iec standard. design notice : where residual-current-operated protective device (rcd) is used for protection in case of direct or indirect contact, only rcd of type b is allowed on the supply side of this electronic equipment (ee). otherwise another protective measure shall be applied such as separation of the ee from the environment by double or reinforced insulation or isolation of ee and supply system by a transformer. (extract from en51078) * use the inverter under the conditions of overvoltage category ii and contamination level 2 or higher specified in iec664. (a) to meet the overvoltage category ii, insert an en or iec standard- compliant earthed star connection isolation transformer in the input of the inverter. (b) to meet the contamination level 2, install the inverter in a control box protected against ingress of water, oil, carbon, dust, etc. (ip54 or higher). * on the input and output of the inverter, use cables of the type and size set forth in en60204 appendix c. * the operating capacity of the relay outputs (terminal symbols a, b, c) should be 30vdc, 0.3a. * the terminals indicated as the input and output terminals for control circuit on page 14 are isolated safely from the main circuit. environment during operation in storage during transportation ambient temperature -10 c to +50 c (14 f to 122 f) -20 c to +65 c (-4 f to 149 f) -20 c to +65 c (-4 f to 149 f) ambient humidity 90%rh or less 90%rh or less 90%rh or less ambient altitude 1,000m (3280.80feet) 1,000m (3280.80feet) 10,000m (32808.00feet) details are given in the technical information "low voltage directive conformance guide" (bcn-a21041-203). please contact your sales representative. 2 c h a p t e r 3 o p e r a t i o n this chapter provides the basic "operation/control" for use of this product. always read this chapter before using the equipment. 3.1 pre-operation information ........................................ 48 3.2 about the control panel............................................ 51 3.3 operation.................................................................. 58 chapter 3 operation/control chapter 1 chapter 2 chapter 3 chapter 4 chapter 5 chapter 6 3.1 pre-operation information 48 3 operation/control 3.1 pre-operation information 3.1.1 types of operation modes the inverter can be operated in any of "pu operation mode", "external operation mode", "combined operation mode" and "communication operation mode". prepare required instruments and parts according to the operation mode. for the way of changing the operation mode, refer to page 54.

(fr-pu04). note: 1. indicates the parameter of which setting is ignored when the general- purpose magnetic flux vector control mode is selected. 2. since calibration is made before shipment from the factory, the settings differ slightly between inverters. the inverter is preset to provide a frequency slightly higher than 60hz. 3. when the control panel is used and the setting is 100hz or more, the setting increments are 0.1hz. the setting increments are 0.01hz when the communication made. 4. the setting depends on the inverter capacity: (0.1k to 3.7k)/(5.5k to 7.5k). 5. set to 85% of the rated inverter current for the 0.1k to 0.75k. 6. if "2" is set in pr. 77 (parameter write inhibit selection), the setting cannot be changed during operation. 7. the half-tone screened parameters allow their settings to be changed during operation if "0" (factory setting) has been set in pr. 77 (parameter write inhibit selection). (however, the pr. 72 and pr. 240 values may be changed during pu operation only.) 8. the setting range changes with the inverter: 0.2kw to 7.5kw, 9999 for the 400v class. 9. pr. 249 and pr. 900 are not available for the 400v class. 10. setting may be made on the 400v class inverter only. 11. the setting depends on the inverter capacity: 4% for the fr-e540-5.5k and 7.5k-na. 12. for the fr-e540-5.5k and 7.5k-na, the factory setting is 10s. 4 parameter list parameters 69 4.1.2 list of parameters classified by purpose of use set the parameters according to the operating conditions. the
