Motor can start-up well from cold-start every times. Then It has run full load for several hours continuously.
Later on motor housing became very hot.
Then we off the motor for 3 min, and on again.
It was found that motor fail to start-up under hot condition every time.
why? and how to solve it?
I'm not sure whether it was about stator resistance become much more or not.

Hi,

Can you check if there were any faults shown by the controller? It is possibly due to the motor tuning parameters.
Please verify the value that was set for "NTC Over temperature voltage threshold" parameter? Can you please share the .mc2 file of the design if possible?

Thanks,
Hari
