What causes an underload error on a Power Electronics SD300 Inverter?
- KKathryn PattersonSep 2, 2025
The motor connected to the Power Electronics Inverter is working with insufficient load. The drive trips when its current is within the values set in parameters Pr.29 and Pr.30, exceeding the time limit set in parameter Pr.28. The protection is enabled if parameter Pr.27 is set to a value other than 0 ('NONE').
