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.
Over-Torque Detection Selection (Motor 3)
Over-Torque Detection Selection (Motor 4)
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
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.
Over-Torque Detection Level (Motor 3)
Over-Torque Detection Level (Motor 4)
10–250% (100% corresponds to the rated current of the drive)
Over-Torque Detection Time (Motor 3)
Over-Torque Detection Time (Motor 4)
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.
