  • Frequency does not rise with blower

    Our suggestion is to adjust the following parameters:1. Set Pr.14 = 0. If the V/F pattern for variable-torque load (Pr.14 = 1) is used, the current may incre... More Details >>

  • Inverter drive of 400 V class motor

    When the wiring between the inverter and motor is long, surge voltage occurs at the terminal of the motor.This surge voltage deteriorates insulation of the m... More Details >>

    • No:21926
    • Release Date:2018/08/22 16:30
  • Automatic overload control of inverter

    The inverter has the current limit function. This automatically controls the frequency so that the preset current value may not be exceeded. (Note that the m... More Details >>

  • Concurrent monitoring of running frequency, output voltage, and output current

    Add an analog output by the FR-A5AY.Monitor the three output; output AM (0 to 5 (10) V) and optional 4 to 20 mA, and 0 to 5 (10) V. More Details >>

    • No:21959
    • Release Date:2018/08/22 16:30
  • Surge voltage of 400 V motor

    When the wire between the 400 V inverter and motor is long (20 m or longer), surge voltage occurs momentarily. This voltage is as two or more times as the DC... More Details >>

    • No:21404
    • Release Date:2018/08/22 16:27
  • Use of the DC reactor

    It can be used in terms of the specifications. However, it is recommended to update the reactor and inverter at the same time because the DC reactor was manu... More Details >>
