  Pr.06.08 to Pr.06.12 store the five most recent faults that occurred. After clearing the cause of the faults, use 
the RESET command to reset the drive. 
 
06.13 
Motor Disconnection Detection Time 
Unit: 1
  Settings  0.1–60.0 sec.   Default: 0.0
    0.0: Disable  
06.14  Motor Disconnection Detection Current Level 
  Settings  10–100%  Default: 30
  Use Pr.06.13 with Pr.06.14. When three-phase imbalance occurs among three-phase motors and the 
imbalance reaches Pr.06.14 setting percentage (the percentage is 100% equal to the AC motor drive's rated 
current settings in Pr.00.01), and lasts the time set in Pr.06.13, OPHL warning displays and the drive stops to 
prevent the motor from damage due to the three-phase unbalanced operation.
