If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50 C. The surface temperature of the Inverter may reach 30 C higher than the ambient tem- perature.

  • Page 28: Ground Wiring

    Chapter 3 Cable Length between Inverter and Motor If the cable between the Inverter and the motor is long, the high-frequency leakage cur- rent will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in n37) as shown in the table below.

  • Page 29: Wiring Control Circuit Terminals

    Chapter 3 Note Minimize the total length (5 m or less) between the ground electrode and the ground terminal, and also use a thick wire (1.25 m or more). Leakage current flows through the Inverter. Therefore, if the distance between the ground elec- trode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.

    Chapter 7 7-1 Notes on Using Inverter for Motor 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 86 Chapter 7 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 be operated in variable speed mode.
  • Page 87 Chapter 7 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.
