142: Auto-tune error 1 (DC test stage) (AuE1)
143: Auto-tune error 2 (High frequency test stage) (AuE2)
144: Auto-tune error 3 (Rotary test stage) (AuE3)
149: Auto-tune error 5 (AuE5)
 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 also
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.
0: No function
1: Continue operation after over-torque detection during constant speed
operation
2: Stop after over-torque detection during constant speed operation
3: Continue operation after over-torque detection during RUN
4: Stop after over-torque detection during RUN
