Cause : Inverter overload trip comes when the temperature of the output transistor elements exceeds the protection level with a rated output current or higher flowing without the overcurrent trip (E.OC[]), the inverter output is stopped. (Overload capacity 150% 60 s

1. Check that acceleration/deceleration time is not too short.
2. Check that torque boost setting is not too large (small).
3. Check that load pattern selection setting is appropriate for the load pattern of the using machine.
4. Check the motor for the use under overload.
5. Set the acceleration/deceleration time longer.
6. Adjust the torque boost setting.
7. Set the load pattern selection setting according to the load pattern of the using machine.
