Analysis of common problems of inverter - Delixi
1. Why does the maintenance function of the inverter operate when the clutch is connected to the load?
When the load is connected with a clutch, at the moment of connection, the motor changes sharply from the no-load condition to the area with a large slip rate, and the large current flowing through causes the inverter to trip over the current and cannot work.
