Page 41: 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 42 EMC and leakage currents Selection of rated sensitivity current of earth (ground) leakage current breaker When using the earth leakage current breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency. Breaker designed for harmonic and Ig1, Ig2: Leakage currents in wire path during commercial surge suppression power supply operation...
Page 43: 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 44 EMC and leakage currents Propagation Path Measures 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 45: 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 46: Harmonic Suppression Guideline In Japan
EMC and leakage currents 3.1.4 Harmonic suppression guideline in Japan Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guideline was established to protect other consumers from these outgoing harmonic currents. The three-phase 200V input specifications 3.7kW or less are previously covered by "Harmonic suppression guideline for household appliances and general-purpose products"...
Page 47 EMC 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(Ki Pi) [kVA]...
Page 48: 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 49: 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 50: 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 51: Precautions For Use Of The Inverter
Precautions for use of the inverter Precautions for use of the inverter The FR-E700 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 52 Precautions for use of the inverter (12) Across P/+ and PR terminals, connect only an external regenerative brake discharging resistor. Do not connect a mechanical brake. The brake resistor cannot be connected to the 0.1K or 0.2K. Leave terminals P/+ and PR open. Also, never short between these terminals.

The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor. Check if Y12 signal is output when inputting the start signal to the inverter (forward signal is STF signal and reverse signal is STR signal).

The DC bus voltage of the inverter is about times as input voltage. When the input voltage is 220VAC, bus voltage is approximately 311VDC. When the input voltage is 440VAC, bus voltage is approximately 622VDC.
