Page 60: 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 62: 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 63 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 64: 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.

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 69 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 344 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 345 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 346 Communication operation and setting (5) Message format types The message formats corresponding to the function codes in Table 1 on page 335 will be explained. Read holding register data (H03 or 03) Can read the description of 1) system environment variables, 2) real-time monitor, 3) alarm history, and 4) inverter parameters assigned to the holding register area (refer to the register list (page 341)).

Page 350 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.

Page 430: 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 432: 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 433: 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.

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 540V to 600V is output when no load is connected and voltage decreases when a load is connected.
