• Automatic restart after instantaneous power failure function with frequency search
  
  

  Detection of coasting speed (frequency search function) prevents the motor speed from decreasing at a restart, starting the motor smoothly with less output current.

• Power-failure deceleration stop function/operation continuation at instantaneous power failure function

  The motor can be decelerated to a stop when a power failure or undervoltage occurs to prevent the motor from coasting.
  This function is useful to stop a motor at power failure as a fail safe of machine tool, etc.
  With the new operation continuation function at instantaneous power failure, the motor continues running without coasting even if an instantaneous power failure occurs during ^*1

• Brake sequence mode......is useful for mechanical brake control of a lift.
• Regeneration avoidance function......prevents regenerative overvoltage in a pressing machine.
• Optimum excitation control......can save more energy with the maximum motor efficiency control.
• Main circuit power supply DC input......can be connected to DC power supply.
• Enhanced I/O terminal function......supports switchover of analog input (voltage / current).
• Password function......is effective for parameter setting protection.

and so on

• *1The inverter may trip and the motor may coast depending on the load condition.

Energy saving for fans and pumps

• Load pattern selection (Pr. 14)
  Optimal output characteristics (V/F characteristics) for application or load characteristics can be selected.
• Optimum excitation control (Pr. 60)
  With Optimum excitation control to achieve the highest motor efficiency, further energy saving can be achieved.
