These two fault codes will be displayed when output current exceeds the over- torque detection level (Pr.06-07 or Pr.06- 10) and exceeds over-torque detection(Pr.06-08 or Pr.06-11) and it is set 2 or 4 in Pr.06-06 or Pr.06-09.
1. Check whether the motor is overloaded.
2. Check whether motor rated current
setting (Pr.05-01) is suitable
3. Take the next higher power AC motor
drive model.
