  • Page 4 Make sure that these protective covers are on the product before use. Consult your OMRON representative when using the product after a long period of storage. WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
  • Page 5 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 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 be- cause the Inverter speed can be easily changed from low to high.

    Chapter 5 Operation Make sure that jump frequencies 1 to 3 determined with the constants set in n56 to n58 and the constant set in n59 for the jump width are appropriate. •The preset output frequency exceeds the upper-limit frequency. The upper-limit frequency can be obtained from the following formula.
  • Page 98 Chapter 5 Operation H Regular Maintenance Check the items below during regular maintenance. Before starting inspection, always turn the power off, then wait at least one minute after all indicators on the front panel go off. Touching terminals immediately after turning the power off may cause an electrical shock.

    Chapter 7 Appendix A 7-1 Notes on Using Inverter for Motor H Using Inverter for Existing Standard Motor When a standard motor is operated with this Inverter, a power loss is slightly higher than when operated with a commercial power supply. In addition, cooling effects also decline in the low-speed range, resulting in an increase in the motor temperature.
  • Page 107 Chapter 7 Appendix A D Vibration The 3G3EV series employs high carrier PWM control to reduce motor vibration. When the motor is operated with this Inverter, motor vibration is almost the same as when op- erated with a commercial power supply. However, motor vibration may become greater in the following cases: •Resonance with the natural frequency of mechanical system Take special care when a machine that has been operated at a constant speed is to...

    Chapter 7 Appendix A D Gearmotor The speed range for continuous operation differs according to the lubrication method and motor manufacturer. In particular, continuous operation of an oil-lubricated motor in the low speed range may result in burning. If the motor is to be operated at a speed high- er than 60 Hz, consult with the manufacturer.
