  • Real sensorless vector control

    For tuning of a single motor with no load, set Pr.96 to "101". When a load is connected, set Pr.96 to "1" (without motor rotation). Since Real sensorless vec... More Details >>

  • FR-A701

    It is protected not by observing the temperature directly, but by estimating it from the current value, output frequency, and carrier frequency. More Details >>

    • No:20871
    • Release Date:2018/08/22 16:24
  • Brake sequence function
