    Thermal relay MCCB Motor Power Inverter supply Line-to-line static capacitances Line-to-line leakage currents path  Precautions • Use Pr.9 Electronic thermal O/L relay. • If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting. Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.
  • Page 71  EMI measures to reduce electromagnetic noises that are radiated by the inverter to cause the peripheral devices to malfunction Inverter-generated noises are largely classified into those radiated by the inverter itself and by the I/O cables connected to its main circuit, those electromagnetically and electrostatically induced to the signal cables of the peripheral devices close to the power cable connected to the inverter main circuit, and those transmitted through the power cables.

    Power supply harmonics 3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.

  • Page 74: Installation Of A Reactor

    Installation of a reactor When the inverter is connected near a large-capacity power transformer (500 kVA or more) or when a power factor correction 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 AC reactor, which is available as an option.

  • Page 75: Power Shutdown And Magnetic Contactor (Mc)

    Power shutdown 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 24 for selection.) • To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).
  • Page 76 NOTE • Before wiring or inspection for a PM motor, confirm that the PM motor is stopped. In an application, such as fan and blower, where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open.

  • Page 81: Failsafe System Which Uses The Inverter

    Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function activates and outputs the Fault signal. However, the Fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures the best quality products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to the machine when the inverter fails for some reason.
