3 PRECAUTIONS FOR USE OF THE INVERTER This chapter explains the "PRECAUTIONS FOR USE OF THE 1 INVERTER" for use of this product. Always read the instructions before using the equipment. 3.1 EMC and leakage currents .......................................................... 32 3.2 Installation of power factor improving reactor ......................... 39 3.3 Power-OFF and magnetic contactor (MC) ................................. 40 3.4 Inverter-driven 400V class motor ...........................
EMC and leakage currents 3.1 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. Therefore, take the following measures.
EMC and leakage currents (3) 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.
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. Also, since the inverter chops outputs at high carrier frequency, that could generate electromagnetic noises.
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. The following measures must be taken: Install easily affected devices as far away as possible from the inverter.
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.

Installation of power factor improving reactor 3.2 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) 3.3 (1) 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 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.
Precautions for use of the inverter 3.5 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. (2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter.
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. (13) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Failsafe of the system which uses the inverter 3.6 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.
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).

Always read the instructions before using the equipment. 7.1 7.2 1 2 Inspection items............................................................................ 252 Measurement of main circuit voltages, currents and powers ..
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. zPrecautions for maintenance and inspection For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor.
Inspection items Daily and periodic inspection Area of Inspection General Inspection Item Alarm Occurrence Improve environment Overall unit Check for unusual vibration and noise. Check alarm location and retighten Power supply voltage Check that the main circuit voltages are normal.∗1 Inspect the power supply (1) Check with megger (across main circuit terminals and earth (ground) terminal). Contact the manufacturer (2) Check for loose screws and bolts.
Inspection items 7.1.4 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 its end. It gives an indication of replacement time. The life alarm output can be used as a guideline for life judgement.
Inspection items 7.1.6 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 they will cause the inverter surface paint to peel off. The display, etc. of the operation panel are vulnerable to detergent and alcohol. Therefore, avoid using them for cleaning. 7.1.
Inspection items (1) Cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration is noticed during inspection, the cooling fan must be replaced immediately. zRemoval 1) Push the hooks from above and remove the fan cover. 3.7K or lower 5.5K or higher 2) Disconnect the fan connectors. 3) Remove the fan. 5.5K or higher 3.
Inspection items zReinstallation 1) After confirming the orientation of the fan, reinstall the fan so that the arrow on the left of "AIR FLOW" faces up. AIR FLOW 2) Reconnect the fan connectors. 3) When wiring, avoid the cables being caught by the fan. 5.5K or higher 3.7K or lower 5.5K or higher 3.7K or lower 2. Insert hooks until you hear a click sound. 1. Insert hooks into holes. Example for FR-E740-3.7KNC 1. Insert hooks into holes. 2. Insert hooks until you hear a click sound.
Inspection items (2) Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the adverse effects of ripple currents, etc. The replacement intervals greatly vary with the surrounding air temperature and operating conditions.
Measurement of main circuit voltages, currents and powers 7.2 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. When installing meters etc.
Measurement of main circuit voltages, currents and powers Measuring Points and Instruments Item Power supply voltage V1 Measuring Point R/L1 and S/L2 S/L2 and T/L3 T/L3 and R/L1 ∗3 Power supply side current I1 Power supply side power P1 Measuring Instrument Moving-iron type AC voltmeter ∗4 R/L1, S/L2, T/L3 line Moving-iron type AC current ∗3 ammeter ∗4 R/L1, S/L2, T/L3 and Digital power meter R/L1 and S/L2, (designed for inverter) or S/L2 and T/L3, electrodynamic type single- T/L3 and R/L1 ∗3
Measurement of main circuit voltages, currents and powers 7.2.1 Measurement of powers Use electro-dynamometer type meters (for inverter) for the both of inverter input and output side. Alternatively, measure using electrodynamic type single-phase wattmeters for the both of inverter input and output side in two-wattmeter or threewattmeter method. As the current is liable to be imbalanced especially in the input side, it is recommended to use the threewattmeter method.
Measurement of main circuit voltages, currents and powers 7.2.3 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. In this case, use an approximate-effective value type.
Measurement of main circuit voltages, currents and powers 7.2.7 Insulation resistance test using megger For the inverter, conduct the insulation resistance test on the main circuit only as shown below and do not perform the test on the control circuit. (Use a 500VDC megger.
