If you pull up a basic print online and compare it to what points he's testing, you'll see that he's basically half splitting the diode section and igbt section. Because the incoming and outgoing terminals are tapped in between the diode 6 pack and igbt 6 pack. Also to clear up confusion, he puts the positive probe on the negative DC bus and negative probe on positive DC bus. Even though the top of the circuit is the "more positive side" and the lower circuit is the "more negative side", you have to change your meter polarity so you can forward bias the diodes and IGBTs. Pull up the print and it'll make sense. Hope that helps.

The machine is running an unbalanced charge with large inertia ? I mean that the unbalanced make the motor régénérative during short période. One solution is find the parameter who speak about DC link control (anti régénérative fct). Also, try to put the inverter in Vector control instead u/f. Please, give more détails about alarm History, ref speed ? Output speed ? Output current ? DC link voltage at normal opération.
