Cause : The regen inductor has overloaded comes when in Regen mode, this trip indicates a regen inductor thermal overload based on the Rated Current (Pr 05.007) and the Inductor Thermal Time Constant (Pr 04.015). Pr 04.019 displays the inductor temperature as a percentage of the maximum value. The drive will trip on Inductor Too Hot when Pr 04.019 gets to 100 %.
- Check the load / current through the inductor has not changed.
- Ensure the Rated Current (Pr 05.007) is not zero.
