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.
Noise and leakage currents (3) Selection of rated sensitivity current of earth (ground) leakage breaker When using the earth (ground) leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency: ⋅...
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.
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.
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.
Harmonic suppression measures necessary Equal to or less than upper limit Harmonic suppression measures unnecessary Table 2 Conversion factors for FR-F700 series Class Circuit Type Conversion Factor (Ki) Without reactor K31 = 3.4 With reactor (AC side) K32 = 1.8...
Noise and leakage currents 1) Calculation of equivalent capacity P0 of harmonic generating equipment The "equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic generating equipment and is calculated with the following equation.If the sum of equivalent capacities is higher than the limit in Table 3, harmonics must be calculated with the following procedure: P0 = Σ...
Noise and leakage currents 3) Harmonic suppression technique requirement If the outgoing harmonic current is higher than the maximum value per 1kW (contract power) × contract power, a harmonic suppression technique is required. 4) Harmonic suppression techniques Item Description Reactor installation Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on (FR-HAL, FR-HEL) its DC side or both to suppress outgoing harmonic currents.
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 AC reactor (FR-HAL) AC reactor (kVA)
Inverter-driven 400V class motor 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:...
Precautions for use of the inverter 3.5 Precautions for use of the inverter The FR-F700 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.
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.

Measurement of main circuit voltages, currents and powers 6.2 Measurement of main circuit voltages, currents and powers 6.2.1 Measurement of voltages and currents 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.
Measurement of main circuit voltages, currents and powers Measuring Points and Instruments Measuring Item Measuring Instrument Remarks (Reference Measured Value) Point Across R/L1-S/ Commercial power supply Power supply voltage L2, S/L2-T/L3, T/ Moving-iron type AC voltmeter Within permissible AC voltage fluctuation L3-R/L1 Refer to page 266.
Measurement of main circuit voltages, currents and powers 6.2.2 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.
Measurement of main circuit voltages, currents and powers 6.2.4 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 6.2.7 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 270V to 300V (approximately 540V to 600V for the 400V class) is output when no load is connected and voltage decreases when a load is connected.
