 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.
