● The parameters record when the fault occurs and forces a stop.
● When low voltage at stop fault (LvS) occurs, the fault is not recorded. When low-voltage during operation faults
(LvA, Lvd, Lvn) occur, the faults are recorded.
● When the dEb function is valid and enabled, the drive executes dEb and records fault code 62 to Pr.06-17–06-
22 and Pr.14-70–14-73 simultaneously.

● When you set Pr.14-74 and Pr.14-77 to 1 or 3, a warning message displays but there is no error record.
● When you set Pr.14-74 and Pr.14-77 to 2 or 4, an error message displays and there is an error record.

● When the output current exceeds the over-torque detection level (Pr.14-75 or Pr.14-78) and exceeds the over-
torque detection time (Pr.14-76 or Pr.14-79), the over-torque detection follows the setting of Pr.14-74 or Pr.14-
77.
● When you set Pr.14-74 or Pr.14-77 to 1 or 3, an ot3/ot4 warning displays while the drive keeps running after
over-torque detection. The warning remains on until the output current is smaller than 5% of the over-torque
detection level.
