    Transportation Precautions Caution Do not hold by front cover or panel , instead, hold by the radiation fin (heat sink) while transporting the product. Doing so may result in injury. Caution Do not pull on the cables. Doing so may result in damage to the product or malfunc- tion.
  • Page 6 Caution Install external breakers and take other safety measures against short-circuiting in external wiring. Not doing so may result in fire. Caution Confirm that the rated input voltage of the Inverter is the same as the AC power sup- ply voltage. An incorrect power supply may result in fire, injury, or malfunction. Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual.
  • Page 7 WARNING Be sure to confirm that the RUN signal is turned OFF before turning ON the power supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so while the RUN signal is turned ON may result in injury. Caution Be sure to confirm permissible ranges of motors and machines before operation because the Inverter speed can be easily changed from low to high.

  • Page 62 Chapter 2 Installation Installing a Noise Filter on the Power Supply Side The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to the power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission.
  • Page 63 Chapter 2 Installation Never Short or Ground Output Terminals If the output terminals are touched with bare hands or the output wires come into contact with the Invert- er casing, an electric shock or grounding will occur.

Auto-tuning is the only setting for basic operation with open-loop vector control. When the voltage limit restricted by the input power supply is reached near the rated motor speed, vector control cannot be established and speed accuracy will be reduced.

If a load is connected when auto-tuning is performed, not only will incorrect motor parameters be re- corded, but the motor may operate erratically resulting in dangerous conditions such as loads falling from vertical axis motors.

    Chapter 10 Appendix 10-1 Notes on Using the Inverter for a Motor H Using the Inverter for an Existing Standard Motor When a standard motor is operated with the Inverter, power loss is slightly higher than when operated with a commercial power supply. In addition, cooling effects also diminish in the low-speed range, resulting in an increase in the motor temperature.

  • Page 397: Using The Inverter For Special Motors

    Chapter 10 Appendix Noise Noise is almost the same as when the motor is operated with a commercial power supply. Motor noise, however, becomes louder when the motor is operated at a speed higher than the rated speed (60 Hz). H Using the Inverter for Special Motors Pole-changing Motor The rated input current of pole-changing motors differs from that of standard motors.
