• Page 3: Notation For Safety Precautions

  NOTATION FOR SAFETY PRECAUTIONS Read this instruction manual thoroughly before installation, operation, mainte- nance, or inspection of the V7AZ. In this manual, safety precautions are classi- fied as either warnings or cautions and are indicated as shown below. WARNING Indicates a potentially hazardous situation which, if not avoided, may result in death or serious injury.
• Page 4
  Confirm that all indicators are OFF before proceeding. • Do not perform a withstand voltage test on any part of the Inverter. The Inverter is an electronic device that uses semiconductors, and is thus vul- nerable to high voltage.
• Page 5
  CAUTION (Ref. page) • Lift the Inverter by the heatsinks. When moving the Inverter, never lift it by the plastic case or the terminal cover. Otherwise, the main unit may fall and be damaged. • Mount the Inverter on nonflammable material (i.e., metal).
• Page 6
  Failure to observe this warning may result in an elec- tric shock or a fire. • For 400 V Class, make sure to ground the sup- ply neutral. Failure to observe this warning may result in an elec- tric shock or a fire.
• Page 7
  • Verify that the Inverter rated voltage coincides with the AC power supply voltage. Failure to observe this caution may result in personal injury or a fire. • Do not perform a withstand voltage test on the Inverter. Performing withstand voltage tests may damage semiconductor elements.
• Page 8
  OPERATION WARNING (Ref. page) • Only turn ON the input power supply after con- firming that the Digital Operator or blank cover (optional) are in place. Do not remove the Digital Operator or the covers while current is flowing. Failure to observe this warning may result in an elec- tric shock.
• Page 9
  WARNING (Ref. page) • If an alarm is reset with the operation signal ON, the Inverter will restart automatically. Reset an alarm only after verifying that the operation sig- nal is OFF. Failure to observe this warning may result in injury.
• Page 10
  CAUTION (Ref. page) • If using an Inverter with an elevator, take safety measures on the elevator to prevent the eleva- tor from dropping. Failure to observe this caution may result in injury. • Do not perform signal checks during operation.
• Page 11
  WARNING (Ref. page) • Never touch high-voltage terminals on the Inverter. Failure to observe this warning may result in an elec- trical shock. • Disconnect all power before performing mainte- nance or inspection, and then wait at least one minute after the power supply is disconnected.
• Page 12
  Failure to observe this caution may result in injury. OTHERS WARNING • Never modify the product. Failure to observe this warning may result in an electrical shock or injury and will void the guarantee. CAUTION • Do not subject the Inverter to halogen gases, such as fluorine, chlorine, bromine, and iodine, at any time even during trans- portation or installation.

• Page 60: Using Vector Control Mode

  Vector control requires motor constants. The factory settings constants have been set at the factory prior to shipment. Therefore, when a motor designed for an Inverter is used or when a motor from any other manu- facturer is driven, the required torque characteristics or speed control characteristics may not be maintained because the constants are not suit- able.

  • If the speed is less than the target value, increase the slip compensa- tion gain. • If the speed is more than the target value, reduce the slip compensa- tion gain. Adjustment of the Slip Compensation Time Constant (n112) is normally not required.
