Table 1-5-1 Storage environment Item Specifications Ambient temperature -10 ~+50 degree C (Note 1) Places not subjected to abrupt temperature changes Storage temperature -25 ~+65 degree C or condensation or freezing Note 2 Relative humidity 5 ~95% Atmosphere The product must not be exposed to dust, direct sunlight, corrosive or flammable gases, oil mist, vapor, water drops or vibration. There must be little salt in the atmosphere. 86 ~106kPa (During storage) Atmospheric pressure 70 ~106kPa (During transportation) Note 1: The storage temperature is for a short time during transportation or the like. Note 2: Even if the humidity is within the requirements of the specifications, places with abrupt temperature changes are subject to condensation or freezing. Avoid storing the inverter in such places. (1) Do not place the inverter directly on the floor. (2) If the ambient atmosphere is adverse, wrap the inverter in a vinyl sheet or the like when storing. (3) If humidity may give an ill effect, add a drying agent (such as silica gel) in the package prepared as described in item (2). To store for a long time The long-term storage method of the inverter varies largely according to the environment of the storage site. General storage methods are described below. (1) The storage site must satisfy the requirements of specifications for temporary storage. However, for storage exceeding three months, the upper limit of the ambient temperature shall not exceed 30 °C. This is for the prevention of deterioration of electrolytic capacitors left turned off. (2) The package must be air tight so that moisture will not enter. Add a drying agent inside the package to contain the relative humidity inside the package within 70%. (3) The inverter installed on a unit or control panel and left is likely to be exposed to moisture and dust. If this is the case, remove the inverter and move it to a preferable environment. (4) Electrolytic capacitors left turned off for an extended period of time deteriorate. Do not store for one year or more without turning the power on. 1-62.

Do not install the inverter below a heat sensitive device. Below 100mm (3) The temperature of the heat sink rises to about 90 degrees C during operation of the inverter. Mount the Fig. 2-2-1 inverter on a base made of a material withstanding the temperature rise. Install the inverter on a nonflammable material such as metal. ! ! ! ! WARNING Otherwise fire could occur. (4) When installing the inverter inside a control panel or the like, take full consideration for ventilation so that the ambient temperature of the inverter does not exceed the specification requirements. Do not install the inverter in a poorly ventilated small enclosure. (5) When storing multiple inverters inside a single unit or inside a control panel, horizontal installation is recommended to reduce mutual temperature effects. When an vertical layout is adopted for an unavoidable reason, install a partition plate or the like between inverters to isolate the heat of the lower inverter. Do not allow lint, paper, wood chips, dust, metallic chips or other foreign matter in ! ! ! ! the inverter or do not allow them attached to the heat sink. CAUTION Otherwise fire or an accident could occur. 2-1 2-3 Connection Remove the control terminal block cover to connect the control terminal block. Remove the main circuit terminal block cover to connect the main circuit terminal block. Correctly connect cables taking care of the following precautions. 2-3-1 Basic Connection (1) Be sure to connect the power cables to main circuit power terminals L1/R, L2/S and L3/T or L1/L,L2/N of the inverter. If the power cables are connected to other terminals, the inverter will be broken. As well, check the source voltage for the allowable voltage range specified on the nameplate and so on. (2) Connect the grounding terminal without fail according to national or local electric code to prevent electric shock, fire or other disasters and to reduce electric noise. (3) Use reliable crimp terminals for connection of cables to the terminals. (4) After finishing wiring, check the following. a. Check if the cables are connected correctly. b. Check if there is no failure of connection. c. Check if terminals or cables are short circuited or there is a ground fault. (5) To change connection of an inverter having been turned on The smoothing capacitor in the direct current part of the main circuit takes time to be discharged after it is turned off. To avoid danger, check the DC voltage (across main circuit terminals P (+) and N (-)) for a safety voltage (25 Vdc or lower) using a multi-meter, after the charge lamp is unlit. Wait until the residual voltage is discharged before shorting a circuit, to avoid being hit by sparks caused by the voltage (electric charge). • Be sure to connect the grounding cable without fail. Otherwise electric shock or fire could occur. • Qualified electricians should carry out wiring. ! ! ! ! WARNING Otherwise electric shock could occur. • Perform wiring after checking that the power supply is turned off.

(1) Main circuit power input terminal (L1/R, L2/S, L3/T,L1/L,L2/N) a. Connect the main circuit power input terminals to the power supply through a circuit breaker for circuit (wiring) protection or an earth leakage breaker. There is not need to match the phase sequence. b. It is recommended to connect a magnetic contactor to disconnect the inverter from the power supply to prevent a failure or accident from becoming serious upon activation of the protective function of the inverter. c. Do not turn the main circuit power supply on or off to start or stop the inverter. Instead, use control circuit terminals FWD and REV or the RUN and STOP keys on the keypad panel. If it is unavoidable to turn the main circuit power supply on or off to start or stop the inverter, limit the frequency to once an hour or fewer. d. Do not connect to a single-phase power supply for 3-phase input inverter. (2) Inverter output terminals (U, V, W) a. Connect these terminals to a 3-phase motor with the correct phase sequence. If the direction of rotation does not match the operation direction, change arbitrary two cables among the U, V and W phases. b. Do not connect a phase advance capacitor or surge absorber to the inverter output. c. If the wiring length between the inverter and the motor is extremely long, the stray capacity between cables causes a high frequency current, possibly tripping the inverter due to an overcurrent, increasing the leakage current, or deteriorating the current detection accuracy to cause deterioration of the performance or other phenomena. To prevent such trouble, limit the wiring length of the motor to 50 m for 4.0 kW or a smaller output or to 100 m for a larger output. Note: When a thermal relay is installed in the path between the inverter and the motor, or especially in the case of a 400V system, the thermal relay may malfunction even with a wiring length shorter than 50 m. In such a case, add an OFL filter or lower the Motor sound adjustment (carrier frequency) of the inverter. ...

Because weak analog signals are handled, these signals are especially susceptible to the external noise effects. Route the wiring as short as possible (within 20 m) and use shielded cables. In principle, ground the shield of the shielded cable; if effects of external inductive noises are considerable, connection to terminal 11 may be effective. b. Use twin contacts relay for weak signals if relay is used in the circuit. Do not add a contact to terminal 11. c. When the inverter is connected with an external device outputting the analog signal, a malfunction may be caused by electric noise generated by the inverter according to some type of the circuit of the device. If this happens, connect a ferrite core or capacitor to the device outputting the analog signal. (2) Digital input terminals (FWD, REV, X1 through X5, P24) a. Generally the digital input terminals (FWD, REV, X1-5) are turned on or off in relation to the P24 terminal. b. To use contact input, use a reliable contact free from poor contact. Example: Control relay made by Fuji Electric: HH54PW (3) Transistor output terminals (Y1E-Y2E, CMC) a. Circuit configuration shown in Table 2-3-2 for transistor output is adopted. Take care of the polarity of the external power supply. b. To connect a control relay, connect a surge absorbing diode across the coil of the relay. (4) Others a. Route the wiring of the control terminals as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions. b. Fix the control cables inside the inverter to keep them away from the live parts of the main circuit (such as the terminal block of the main circuit). If the control cables touch the live part of the main circuit, the insulation sheath of the control cable, insulation of which is not reinforced, may be broken to cause a high voltage of the main circuit to be fed to the control signal.

Function codes used for the restart after momentary power failure include H13 and H14. Refer to the description of these codes, too. As well, a rotating motor pickup function can be selected as a starting method after a momentary power failure. (Refer to function code H09 for details of setting.) When the pickup function is used, the speed of the coasting motor is detected and the motor is started without a shock. Because a speed detection time is necessary if the pickup function is made effective, the pickup function should be made ineffective and restart should be made at the frequency effective before the power failure in a system with a large inertia to restore the original frequency, to make the most of the small decrease in the speed of the coasting motor. The effective range of the pickup function is 5 to 120 Hz. If the detected speed is out of the effective range, the inverter restarts according to the regular function of restart after momentary power failure. 5-16 Setting Power failure Power restoration Power failure Power restoration Setting: 2 Setting: 0 Main Main Undervoltage circuit DC circuit DC Undervoltage voltage voltage Synchroni- H13:Wait time Time Output zation frequency Output frequency (Motor speed) Protective function Accelera- Protective 30 relay tion function Active Output terminal 30 relay (Y1-Y2 terminals); ON Setting: 1 IPF signal Main Setting: 3 circuit DC Undervoltage voltage Main circuit Undervoltage DC voltage Time Protective Output function H13:Wait time frequency (Motor speed) 30 relay Active Protective function 30 relay Output terminal (Y1-Y2 terminals); IPF signal Note: The chain line indicates the motor speed. 5-17 F15 Frequency limiter (High) F18 Bias frequency This function obtains the frequency setting from F16 Frequency limiter (Low) addition of the frequency setting in relation to Set the upper and lower limits of the frequency the analog input and a bias frequency.

The torque limiting operation calculates the motor torque from the output voltage, current, resistance of the primary winding of the motor and other data to control the frequency so that the calculated value does not exceed the control value. This operation insures inverter operation without tripping upon abrupt changes in the load torque while the limit value is maintained. ? Select the limit values of the driving torque and braking torque. ? The acceleration/deceleration operation time during activation of this function becomes longer than the set acceleration/deceleration time. When the driving torque is limited during constant speed operation, the frequency is lowered to reduce the load torque. (When the braking torque is limited, the contrary occurs.) Setting range: 20 to 200,999% Set "999" to inactivate the torque limiter. Set only the braking torque to "0" to automatically avoid OU tripping caused by power regeneration. • If the torque limiter has been selected, the inverter may operate at an acceleration/deceleration time or speed different from the set ones. Design the ! ! ! ! WARNING machine so that safety is ensured even in such cases. Otherwise an accident could occur. F42 Torque vector control 1 ? The torque vector control calculates the torque suitable for the load to make the most of the motor torque, and controls the voltage and current vectors to optimum ones according to the calculated value. Setting State of operation Inactive 0 Active 1 ? When "1" (active) is selected, the settings of the following function codes become different from the written ones. 1) F09 "Torque boost 1" Works as "0" value (automatic torque boost). 2) P09 "Slip compensation control" Slip compensation is automatically activated. When "0" is set, the slip compensation amount of a Fuji's standard three-phase motor is assumed. When the setting is other than "0", the written setting is applied. Use the torque vector control function under the following conditions. 1) A single motor If two or more motors are connected, accurate control is difficult. 2) The data of function codes of motor 1 (P03 "Rated current", P06 "No-load current", P07 "%R1" and P08 "%X") must be accurate. If the standard three-phase motor made by Fuji is used, the above data is automatically input when function code P02 "Capacity" is set. When another motor is used, perform auto tuning. 3) The rated motor current must not be too smaller than the rated inverter current. Though it depends on the model, the one smaller by two ranks than the standard applicable motor of the inverter is the allowable smallest motor. 4) The wiring distance between the inverter and motor must be up to 50 m. Too long a wiring distance disables accurate control due to the leakage current flowing through the static capacity between the cable and the ground. 5) When a reactor is connected between the inverter and the motor or when the wiring impedance is large enough to be overlooked, change the data using P04 "Auto tuning". If these conditions cannot be satisfied, change the setting to "0" (inactive). 5-21 Multistep frequency selection (E:Extension Terminal Functions) Combination of input E01 X1 terminal function signals Selected frequency 3 2 1 0 E02 X2 terminal function [SS8] [SS4] [SS2] [SS1] E03 X3 terminal function Selected by F01 or C30 off off off off C05 Multistep frequency 1 off off off on E04 X4 terminal function C06 Multistep frequency 2 off off on off E05 X5 terminal function C07 Multistep frequency 3 off off on on C08 Multistep frequency 4 off on off off The function of each digital input terminal X1 to C09 Multistep frequency 5 X5 can be set arbitrarily using a code. off on off on C10 Multistep frequency 6 off on on off Setting Function C11 Multistep frequency 7 off on on on 0,1,2,3 Multistep frequency selection (1 to 15 C12 Multistep frequency 8 steps) on off off off C13 Multistep frequency 9 4 Acceleration/deceleration selection (1 on off off on step) C14 Multistep frequency 10 on off on off 5 Self holding selection [HLD] C15 Multistep frequency 11 on off on on 6 Coast-to-stop command [BX] C16 Multistep frequency 12 on on off off 7 Error reset [RST] C17 Multistep frequency 13 on on off on 8 External alarm [THR] C18 Multistep frequency 14 on on on off 9 Frequency setting 2 / frequency setting C19 Multistep frequency 15 on on on on 1 [Hz2 / Hz1] Acceleration/deceleration time selection 10 Motor 2 / motor 1 [M2 / M1] Acceleration/deceleration time set to function 11 DC brake command [DCBRK] codes E10 and E11 can be selected according to 12 Torque limit 2 / torque limit 1 [TL2 / external digital input signal switching.

Protective Operation 6-1 List of Protective Operations When an error occurs to the inverter, a protective function is activated to trip the inverter immediately, displaying the name of the alarm at the LED and allowing the motor to coast to stop. Table 6-1-1 List of alarm display and protective operations Name of alarm Display Description of operation OC1 During The protective function is activated when an overcurrent flowing acceleration in the motor or a short circuit or ground fault in the output circuit Overcurrent causes the instantaneous inverter output current to exceed the OC2 During protection overcurrent detection level. deceleration OC3 During constant speed operation OU1 During The protective function is activated when the regenerative power acceleration from the motor increases to cause the DC link voltage of the main circuit to exceed the overvoltage detection level (Approx. OU2 During Overvoltage 400 Vdc for 200V class, Approx. 800V for 400V class). When an deceleration protection excessive voltage is added to the source voltage, the inverter OU3 During constant trips due to the overvoltage, but inverter protection against the speed operation overvoltage is impossible. Undervoltage LU The protective function is activated when the source voltage drops to cause the DC protection link voltage in the main circuit to become lower than the undervoltage detection level (Approx. 200 Vdc for 200V class, Approx. 400V for 400V class). If F14 Restart after momentary power failure has been selected, no alarm display is given. If the voltage drops below the control power maintenance level, no alarm is displayed. Input phase Lin When the inverter is operated while one of the three phases of the power supply loss connected to the main power supply input terminals L1/R, L2/S and L3/T of the main protection circuit is missing or there is an unbalance among the three-phase voltages, the rectifying diode or smoothing capacitor of the main circuit may be broken. The inverter is stopped upon an alarm in these cases. Heat sink OH1 The protective function is activated when the temperature of the heat sink of the overheat inverter is high because of a broken cooling fan or for other reasons. External alarm OH2 The protective function is activated by a contact signal from an alarm contact of the input external device such as the braking unit, braking resistor, and external thermal overload relay connected to the control circuit terminal (THR). Or an overheat protective function is activated by the PTC thermistor. Braking dbH If the electronic thermal overload relay (for braking resistor) has been selected for resistor function code F13, the protective function is activated upon a high operation overheat frequency of the braking resistor to prevent the resistor from being burned due to the temperature rise. Motor 1 OL1 If electronic thermal overload relay 1 has been selected for function code F10, the overload protective function is activated by a motor current exceeding the set operation level. Motor 2 OL2 If motor 2 has been selected and driven and electronic thermal overload relay 2 has overload been selected for function code A06, the protective function is activated by the current in motor 2 exceeding the set operation level. Inverter OLU The protective function is activated by an output current exceeding the overload overload current rating to protect the semiconductor elements in the main circuit of the inverter from high temperatures. Memory error Er1 The protective function is activated by a data writing error or other errors in the memory.

Take care of the following items during work. 8-1 Daily Inspection Visually inspect errors in the state of operation from the outside without removing covers while the inverter operates or while it is turned on. 1) Check if the expected performance (satisfying the standard specification) is obtained. 2) Check if the surrounding environment satisfies the standard specification. 3) Check that the display of the keypad panel is free from errors. 4) Check for abnormal noise, excessive vibration and bad smell. 5) Check for traces of overheat, discoloration and other defects. 8-2 Periodic Inspection After stopping the operation, turn the power off and remove the front cover to perform periodic inspection. The smoothing capacitor at the DC section of the main circuit takes time to be discharged after the power is turned off. After checking that the charge lamp (CRG) is unlit, check that the DC voltage is lower than the safety level (25 VDC) using a multimeter or the like before starting work. • Turn the power off and wait for at least five minutes before starting inspection. (Further, check that the charge lamp is unlit and measure the DC voltage across the P (+) and N (-) terminals to check that it is lower than 25V.) Otherwise electric shock could occur. • Maintenance and inspection and parts replacement should be made only by ! ! ! ! WARNING appointed persons. (Take off the watch, rings and other metallic matter before starting work.) (Use insulated tools.) • Never remodel. Otherwise electric shock or injuries could occur.

The capacitor life forecast signal is issued at the Y1 and Y2 terminals according to the measured capacitance after the capacitance of the capacity reaches 85%. (1) Measurement of capacitance of capacitor in main circuit This inverter is provided with a function where the capacitance of the main circuit capacitor is automatically measured upon shutoff of the inverter under certain conditions and it is displayed on the keypad panel upon power-up. The capacitance of the capacitor is displayed in the reduction ratio (% display) of the initial value stored inside the inverter before shipment. Procedure of measurement of capacitor capacitance 1. Remove the optional card from the inverter if it is mounted. Disconnect the braking unit or direct current bus to another inverter from the P (+) and N (-) terminals of the main circuit if there is any. The power factor improving reactor (DC reactor) may not be disconnected. 2. Turn the digital inputs (FWD, REV, X1-X5) at the control terminals off. Disconnect the RS 485 communication terminal if it is connected. 3. Turn the main power supply on. Check that the cooling fan rotates. Check that the inverter is stopped. (The "OH2 external alarm" caused by deactivated digital input terminals does not cause a problem.) 4. Turn the main power supply off. 5. After the charge lamp is unlit completely, turn the main power supply on again. 6. Monitor function code H42 to check the capacitor capacitance (%). (2) Life of cooling fan Function code H43 indicates the total operation time of the cooling fan. The time is integrated in units of an hour and fractions shorter than an hour are ignored. The actual life of the fan is largely effected by the temperature. Take the time as a measure. Table 8-2-2 Measure for judgment of life based on maintenance data Part Judgment level Main circuit capacitor 85% or lower of the initial value 30,000 hours (4.0 kW or less), 25,000 hours (5.5 kW Cooling fan or more) *1 *1: Assumed life of cooling fan at ambient inverter temperature of 40 degree C. 8-38-3 Measurement of Electrical Amounts in Main Circuit Because the voltage and current of the power supply (input) of the main circuit of the inverter and the output (motor) include harmonic components, the indicated value varies according to the type of the meter. Use meters indicated in Table 8-3-1 when measuring with meters for commercial frequencies. Marketed power factor meters measuring phase difference between the voltage and current cannot measure the power factor. To obtain the power factor, measure the power, voltage and current on each of the input and output sides and calculate in the following formula. In case of Three-phase In case of Single-phase Electric power[W] Electric power[W] Power factor = ×100[%] Power factor = ×100[%] Voltage[V]× Current[A] 3× Voltage[V]× Current[A] Table 8-3-1 Meters for measurement of main circuit Input (power supply) side Output (motor) side Link voltage (P(+)-N(-)) Voltage Current Voltage Current Ammeter Voltmeter Wattmeter Ammeter Voltmeter Wattmeter DC voltmeter A , , V , , W , , A , , V , , W , , V R S T R S T R S T U V W U V W U V W Rectifier or Digital Moving iron Moving iron Rectifier Digital Moving coil moving iron power type type type power meter type type meter Note) When the output voltage is measured by a rectifier type, an error may be included. To increase the accuracy, use a digital AC power meter. (L1/L) (L2/N) Fig. 8-3-1 Connection of meters 8-4 Symbol of Type of Name of Item meter meter meter ?? 8-4 Insulation Test Because an insulation test is made in the factory before shipment, avoid a Megger test. If a Megger test is unavoidable, follow the procedure below. Because a wrong test procedure will cause breakage of the inverter, take sufficient care. A withstand voltage test will cause breakage of the inverter similarly to the Megger test if the test procedure is wrong. When the withstand voltage test is necessary, contact your dealer or nearest Fuji Electric's branch. (1) Megger test of main circuit 1) Use a 500 VDC Megger and shut off the main power supply without fail during measurement. 2) If the test voltage leaks to the control circuit due to the wiring, disconnect all the control wiring. 3) Connect the main circuit terminals with a common cable as shown in Fig. 8-4-1. 4) The Megger test must be limited to across the common line of the main circuit and the ground terminal ( ). G 5) M or a larger value displayed at the Megger indicates a correct state. (The value is for a discrete inverter.) (L1/L) (L2/N) Fig. 8-4-1 Megger test (2) Do not perform a Megger test or withstand voltage test to the insulation test control circuit of the control circuit. Prepare a high resistance range tester for the control circuit. 1) Disconnect all the external wiring from the control circuit terminals. 2) Perform a continuity test to the ground. 1 M or a larger measurement indicates a correct state. (3) External main circuit and sequence control circuit Disconnect all the inverter terminals so that the test voltage is not applied. 8-5 Replacement Parts The life of the part is determined by the type of the part. The life of the part varies according to the environment and operating conditions, and replacement according to Table 8-5-1 is recommended. 8-6 Inquiries about Product and Guarantee Table 8-5-1 Replacement parts (1) When making an inquiry Standard Replacement Name of part replacement method and others Upon breakage of the product, uncertainties, years failure or inquiries, report the following Cooling fan Replace with a new information to your dealer or nearest Fuji 3 years part.

The inverter always waits for a write request (selecting) or a read request (polling) from the host. The inverter, when receiving in the wait state a request frame to the own station from the host, returns a response frame. Upon polling, it returns data together. In the case of broadcasting (selection of all stations in a batch), no response is returned. ·Polling/selecting Host Request frame Request frame Inverter Response frame Response interval time +(0 ~10ms) 10 msec or longer ·Broadcast Host Request frame Request frame Inverter No response frame 10 msec or longer 9-13(3) Transmission procedure 1) Set communication functions H30 through H39. 2) Make communication according to transmission frames. 3) If no response returns for one second from the inverter upon a frame from the host, retry communication. Several retries indicate certain errors. Make investigation. 4) If no communication is received from the host for 30 seconds after the first operation command is received, the inverter judges a transmission breakdown error and shuts down the inverter output, leaving the motor to coast to stop. 5) After consecutive eight communication errors, the inverter output is shut down and the motor coasts to stop. (4) Host controller transmission procedure Do not send the next frame unless the response is returned. If the inverter does not respond for longer than the standard time, timeout should be judged and retry should be performed. If a retry is started before timeout, normal reception may become impossible, so that timeout should be judged correctly. The timeout time is one second in the selecting mode and 0.5 second in the polling mode. In the retry sequence, send the same frame again as that sent before no response, or send a polling (M26: communication error monitor) frame for reading an error, and check for a normal response. (Judge the timeout again during the check.) If a normal response is returned, a transient transmission error due to noise or the like is indicated, and correct communication can be continued. If retries occur frequently, any abnormalities are probable. In-depth investigation is necessary. If no response is returned, continue retrying. If there are three retries, there is some trouble in the hardware or software of the host controller. Terminate the software of the host controller and investigate. No error code is returned in the case of negative acknowledgment of a short frame. Judge the error code using the communication error monitor (M26) separately. 9-149-4-5 Standard Frame The ASCII code character method is employed. A standard frame has a fixed length of 16 bytes. Using optional frames (12 bytes or 8 bytes), the transmission speed can be increased.

(4) Response character (ASCII; ACK/NAK) The inverter sets ACK (06H) to recognize a request. NAK (15H) is set when the request from the host includes a logical error. 9-17(5) Command type character In a standard frame, set "R" in ASCII for a polling (reading) request, or set "W" in ASCII for a selecting (writing) request. Set "E" in ASCII for a resetting command. Only the upper case characters are valid. In a short frame, the function is directly designated using a command type character.

Set in the upper case. Example. When the binary sum is "17EH"› The upper digit of the checksum is "7" in ASCII. The lower digit of the checksum is "E" in ASCII. 9-4-8 Broadcasting An operation command or frequency command destined to station address "99" is received and processed by all the inverters as broadcasting. However, no response is issued by the inverters. 9-189-4-9 Communication Error Code The inverter detects the following errors. The error code is in hexadecimal notation. Table 9-4-4 Communication error code Error code Name of error Description (hexadecimal) The checksum of the frame sent to the own station 47H Checksum error is in discrepancy. 48H Parity error The parity is in discrepancy. Reception error other than above (framing, 49H Others overrun) The enquiry character or the end-of-text character 4AH Format error in the transmitted frame is in an incorrect position. A code other than designated commands 4BH Command error (standard and option) is sent. 4EH Function code error A request for an unknown function code is issued. A write prohibited function or in-operation write 4FH Write disable prohibited function is written during operation. 50H Data error Data exceeding the standard range is written. The inverter does not return NAK in response to errors 47 through 49 above. It issues no response. In the case of errors 4A through 50, an NAK response with an NAK code in the response character field and the two digit hexadecimal error code in the data field is returned. The latest error can be referred to using the transmission error end code monitor (M26). 9-4-10 Data Type (1) In the case of value data 16 bit data is expressed in a hexadecimal and set using four ASCII codes. Concretely speaking, the data is between "0000" and "FFFF". Decimal fractions are weighted into integers. Refer to the corresponding section because the weight varies according to each piece of function data. In some functions, the negative value is expressed in two's complement. The bit data is converted into the hexadecimal and expressed. The acknowledgement sent from the inverter in response to a selecting (writing) request is the writing data. In the negative acknowledgement, the error code is returned in two hexadecimal characters. Set "0000" or an arbitrary letters and numbers in the data to be transmitted to the inverter in a polling (reading) frame. Example: Frequency data, weight 100 times 120.00Hz 120 ×100=12000=2EE0H The data is "2" in ASCII, "E" in ASCII, "E" in ASCII and "0" in ASCII in order from the first character to the fourth character.

Electromagnetic Compatibility (EMC) [Available only inverter for with CE mark ] 12-1General In accordance with the provisions described in the European Commission Guidelines Document on Council Directive 89/336/EEC,Fuji Electric Co., Ltd. has chosen to classify the FVR-E11S range of inverters as "Complex Components". Classification as a "Complex Components" allows a product to be treated as an "apparatus", and thus permits compliance with the essential requirements of the EMC Directive to be demonstrated to both an integrator of FVR inverters and to his customer or the installer and the user. FVR inverters is supplied `CE-marked', signifying compliance with EC Directive 89/336/EEC when fitted with specified filter units installed and earthed in accordance with this sheet. This Specification requires the following performance criteria to be met. EMC product standard EN61800-3/1997 Immunity : Second environment ( Industrial environment ) Emission : First environment ( Domestic environment ) Finally, it is customer’s responsibility to check whether the equipment conforms to EMC directive. 12-2 Recommended Installation Instructions It is necessary that to conformed to EMC Directive, these instructions must be followed. Follow the usual safety procedures when working with electrical equipment. All electrical connections to the filter, Inverter and motor must be made by a qualified electrical technician. 1) Use the correct filter according to Table 12-2-1. 2) Install the Inverter and filter in the electrically shielded metal wiring cabinet. 3) The back panel of the wiring cabinet of board should be prepared for the mounting dimensions of the filter. Care should be taken to remove any paint etc. from the mounting holes and face area of the panel. This will ensure the best possible earthing of the filter. 4) Use the screened cable for the control , motor and other main wiring which are connected to the inverter, and these screens should be securely earthed. 5) It is important that all wire lengths are kept as short as possible and that incoming mains and outgoing motor cables are kept well separated. " To minimize the conducted radio disturbance in the power distribution system, the length of the motor-cable should be as short as possible. " Table 12-2-1 RFI filters Max.
