Page 47: Emc And Leakage Currents
EMC and leakage currents EMC 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 static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.

Page 49: Emc Measures
EMC and leakage currents 3.1.2 EMC measures Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.
Page 50 EMC and leakage currents Propagation Measures Path When devices that handle low-level signals and are liable to malfunction due to electromagnetic 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 electromagnetic noises.
Page 51: Power Supply Harmonics
EMC 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. Take the following countermeasure suppression techniques.
Page 52: Installation Of Power Factor Improving Reactor
Installation of power factor improving reactor Installation of power factor improving reactor When the inverter is connected near a large-capacity power transformer (500kVA 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 an optional reactor (FR-HAL, FR-HEL).
Page 53: Power-Off And Magnetic Contactor (Mc)
Power-off and magnetic contactor (MC) Power-off and magnetic contactor (MC) Inverter input side magnetic contactor (MC) On the inverter input side, it is recommended to provide an MC for the following purposes. (Refer to page 4 for selection.) 1) To release the inverter from the power supply when the fault occurs or when the drive is not functioning (e.g. emergency stop operation).
Page 54: Inverter-Driven 400V Class Motor
Inverter-driven 400V class motor 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:...
Page 55: Precautions For Use Of The Inverter
(11) Across P/+ and PR terminals, connect only an external regenerative brake discharging resistor. Do not connect a mechanical brake. The brake resistor can not be connected to the FR-D720-008 and 014, FR-D720S-008 and 014, FR-D710W-008 and 014. Never short between terminals P/+ and PR.

Page 270: Precautions For Maintenance And Inspection
Inspection items The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors.

Inspection items 6.1.4 Display of the life of the inverter parts The self-diagnostic alarm is output when the life span of the control circuit capacitor, cooling fan and each parts of the inrush current limit circuit is near to give an indication of replacement time. The life alarm output can be used as a guideline for life judgement.
Page 273: Checking The Inverter And Converter Modules
Inspection items 6.1.5 Checking the inverter and converter modules <Preparation> (1) Disconnect the external power supply cables (R/L1, S/L2, T/L3) and motor cables (U, V, W). (2) Prepare a tester. (Use 100Ω range.) <Checking method> Change the polarity of the tester alternately at the inverter terminals R/L1, S/L2, T/L3, U, V, W, P/+ and N/-, and check for continuity.
Page 274: Cleaning
Inspection items 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. NOTE Do not use solvent, such as acetone, benzene, toluene and alcohol, as these will cause the inverter surface paint to peel off. The display, etc.

Page 278: Measurement Of Main Circuit Voltages, Currents And Powers
Measurement of main circuit voltages, currents and powers 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 279 Measurement of main circuit voltages, currents and powers Measuring Points and Instruments Item Measuring Point Measuring Instrument Remarks (Reference Measured Value) R/L1 and S/L2 Commercial power supply Power supply voltage Moving-iron type AC S/L2 and T/L3 Within permissible AC voltage fluctuation (Refer to voltmeter T/L3 and R/L1 ∗4 page 280)
Page 280: 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 281: 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.
