3 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 3.1 EMC and leakage currents .......................................................... 38 3.2 Installation of power factor improving reactor ......................... 43 3.3 Power-off and magnetic contactor (MC) .................................... 44 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. 80 60 40 20 0 1.0 0.7 0.5 0.3 0.2 0.1 0.07 0.05 0.03 0.02 0.1 0.2 2 3.5 8 142238 80150 5.
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: (1)(2)(3) 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.
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-D700 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. (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) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits. Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short terminals 10-5.
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).

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 twoor 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. Examples of process value differences produced by different measuring meters are shown below.
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. In this case, use an approximate-effective value type.
Measurement of main circuit voltages, currents and powers 6.2.7 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.
