ot1
Over Torque 1
Fault
The ot1 and ot2 fault codes appear when the following conditions
occur:
- The output current exceeds the setting in Pr.06-06 (Over-torque
Detection Level (OT1)> and Pr.06-09 (Over-torque Protection
Level (OT2).
- The output current lasts longer than the time setting in Pr.06-07
and Pr.06-10.
- You set Pr.06-05 or Pr.06-08 to 2 or 4.
corrective action
1. Check if the motor is overloaded.
2. Check if the setting in Pr.05-01 IM (Motor Full-load Current)
and Pr.08-01 PM (Motor Full-load Current) are appropriate.
3. If necessary, increase the motor output capacity.
