  • *1 H characteristic: Constant torque load (for general industry)
  • *2 Rated capacity at the output voltage of 220 V
  • *3 When the input voltage is 200 V or above, rated current will be decreased according to the output power.
  • *4 1 minute every 10 minutes
  • *5 The maximum carrier frequency varies with the rated characteristics and the operating status.
  • *6 The frequency setting range for sensorless vector control is 1 to 130 Hz for a four-pole motor (depends on the number of poles).
  • *7 The maximum output frequency is at 5 V, 10 V, and 20 mA.
  • *8 This temperature is for short periods, such as during transportation.
