Q : How to solve over current trip caused by short circuit of GD200A external circuit?
A: The over-current caused by motor winding short-circuit, wiring short-circuit and terminal short-circuit is the most dangerous over-current, because the steepness of the current is very easy to cause damage to the IGBT module. The characteristics of this kind of over-current are: the inverter trips when it is running and cannot work. In this case, do not repeat the test, to carefully check whether there is a short circuit fault in the external circuit.
