    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.

  • Page 51: 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 52

    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 53: 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.

    Installation of a reactor 3.2 Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000kVA 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 the AC reactor (FR-HAL) AC reactor (kVA)

    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. 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 56

    Precautions for use of the inverter 3.5 Precautions for use of the inverter The FR-F700 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 57

    Precautions for use of the inverter (13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter's input side and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.

    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.

  • Page 59

    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).

  • Page 331: Appendix 2 Parameter Clear, Parameter Copy And Instruction Code List

    Appendix 2 Parameter clear, parameter copy and instruction code list These instruction codes are used for parameter read and write by using Mitsubishi inverter protocol with the RS-485 communication. (Refer to page 194 for RS-485 communication) " " indicates valid and " " indicates invalid of "parameter copy", "parameter clear", and "all parameter clear". These parameters are communication parameters that are not cleared when parameter clear (all clear) is executed from RS-485 communication.
