Thank you so much

Very useful information, thanks for the video 👍👍

FC102N showing the earth's fault, . During removing the cable it does not show the earth fault when we are connecting the motor cable it starts showing the earth fault. We checked the cable and motor and found it normal. Then what is the actual reason and what is the solution.

At 5:16, you spoke about high voltage frequency pulses that can find pass to ground through the smallest pinholes of insulation. How can we confirm this is the case? Will a Megger test or insulation resistance test be able to detect such minor pinhole leaks?

Good day..... How does the full service log (M26) would affect the operation/function of the drive?

Uncrewing section not work properly till M/c continuosly run 15/20 minutes. After 15/20 minutes machine work properly and Uncrewing section work properly. When uncrewing section not work then display shown "Uncrewing drive faulty". When such type problem created then we press continuously reset button. Drive alarm showing current limit A59 Please help

in the fc101 models they do not have common current sensors, apparently the measurement is taken through the dc bus, because in my case I have an fc101 and the alarm 16 short circuit persists, having already measured the igbt module correctly
