PRECAUTIONS FOR USE OF THE INVERTER This chapter explains the "PRECAUTIONS FOR USE OF THE INVERTER" for use of this product. Always read the instructions before using the equipment. EMC and leakage currents ............32 Installation of power factor improving reactor ......39 Power-OFF and magnetic contactor (MC) .........
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.
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...
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 46
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.
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.
EMC and leakage currents 3.1.4 Harmonic Suppression Guidelines in Japan Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents. The three-phase 200V input specifications 3.7kW or lower (single-phase 200V power input model 2.2kW or lower are previously covered by "Harmonic Suppression Guidelines for Household Appliances and General-purpose Products"...

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).
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).
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:...
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 points. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
Page 54
Precautions for use of the inverter (12) Across terminals P/+ and PR, connect only an external regenerative brake discharging resistor. Do not connect a mechanical brake. The brake resistor can not be connected to the 0.1K or 0.2K. Leave terminals P/+ and PR open. Also, never short between these terminals.
Failsafe of the system which uses the inverter 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 56
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. 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).
