Page 53: Noise And Leakage Currents
Noise and leakage currents 3.1 Noise and leakage currents 3.1.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
Page 54: Inverter-Generated Noises And Their Reduction Techniques
Noise and leakage currents 3.1.2 Inverter-generated noises and their reduction techniques Some noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to be insusceptible to noises, it handles low-level signals, so it requires the following basic techniques.
Page 55 Noise and leakage currents Noise Propagation Measures Path When devices that handle low-level signals and are liable to malfunction due to noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated noises.
Page 56: Power Supply Harmonics
Noise and leakage currents 3.1.3 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
Page 57: Installation Of A Reactor
Installation of a reactor 3.2 Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000kVA or more) or when a power capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this, always install the optional AC reactor.
Page 58: Power-Off And Magnetic Contactor (Mc)
Power-off and magnetic contactor (MC) 3.3 Power-off and magnetic contactor (MC) (1) Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes.

Page 60: Precautions For Use Of The Inverter
Precautions for use of the inverter 3.5 Precautions for use of the inverter The FR-A700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
Page 61 Precautions for use of the inverter (14) 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.
Page 62: Failsafe Of The System Which Uses The Inverter
Failsafe of the system which uses the inverter 3.6 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.
Page 63 Failsafe of the system which uses the inverter 4) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal. The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor.

Parameter Name Initial Value...
Page 343 Communication operation and setting (2) Outline The Modbus protocol is the communication protocol developed by Modicon for PLC. The Modbus protocol performs serial communication between the master and slave using the dedicated message frame. The dedicated message frame has the functions that can perform data read and write. Using the functions, you can read and write the parameter values from the inverter, write the input command of the inverter, and check the operating status.
Page 344 Communication operation and setting (4) Message frame (protocol) Communication method Basically, the master sends a query message (question) and the slave returns a response message (response). When communication is normal, Device Address and Function Code are copied as they are, and when communication is abnormal (function code or data code is illegal), bit 7 (= 80h) of Function Code is turned on and the error code is set to Data Bytes.
Page 345 Communication operation and setting (5) Message format types The message formats corresponding to the function codes in Table 1 on page 333 will be explained. Read holding register data (H03 or 03) Can read the description of 1) system environment variables, 2) real-time monitor, 3) faults history, and 4) inverter parameters assigned to the holding register area (refer to the register list (page 339)).
Page 346 Communication operation and setting Write multiple holding register data (H06 or 06) You can write the description of 1) system environment variables and 4) inverter parameters assigned to the holding register area (refer to the register list (page 339)).

Page 349 Communication operation and setting Error response An error response is returned if the query message received from the master has an illegal function, address or data. No response is returned for a parity, CRC, overrun, framing or busy error. CAUTION No response message is sent in the case of broadcast communication also.

The life alarm output can be used as a guideline for life judgement.
Page 424: Cleaning
Inspection item 6.1.6 Cleaning Always run the inverter in a clean status. When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol. CAUTION Do not use solvent, such as acetone, benzene, toluene and alcohol, as they will cause the inverter surface paint to peel off. The display, etc.
Page 425 Inspection item (1) Cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration is noticed during inspection, the cooling fan must be replaced immediately.

Page 429: Measurement Of Main Circuit Voltages, Currents And Powers
Measurement of main circuit voltages, currents and powers 6.2 Measurement of main circuit voltages, currents and powers Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured. When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments given on the next page.

Page 431: Measurement Of Powers
Measurement of main circuit voltages, currents and powers 6.2.1 Measurement of powers Using an electro-dynamometer type meter, measure the power in both the input and output sides of the inverter using the two- or three-wattmeter method. As the current is liable to be imbalanced especially in the input side, it is recommended to use the three-wattmeter method.
Page 432: Measurement Of Currents
Measurement of main circuit voltages, currents and powers 6.2.3 Measurement of currents Use a moving-iron type meter on both the input and output sides of the inverter. However, if the carrier frequency exceeds 5kHz, do not use that meter since an overcurrent losses produced in the internal metal parts of the meter will increase and the meter may burn out.
Page 433: Measurement Of Converter Output Voltage (Across Terminals P/+ - N/-)
Measurement of main circuit voltages, currents and powers 6.2.6 Measurement of converter output voltage (across terminals P/+ - N/-) The output voltage of the converter is developed across terminals P/+ - N/- and can be measured with a moving-coil type meter (tester). Although the voltage varies according to the power supply voltage, approximately 800V to 900V is output when no load is connected and voltage decreases when a load is connected.
