Chapter 6 - Parameter Description [FU2]

This function is used to allow the inverter to reset itself for a selected number of times after a fault has occurred. The inverter can restart itself automatically when a fault occurs. To use the speed search function during auto restarting set FU2-22 to ‘xx1x’. See FU2-22 ~ FU2-25.

When an under voltage (LV) fault, inverter disable (BX) or Arm short occurs, the drive does not restart automatically.
