Hello, I have trouble with error EoAn in my Huanyang vfd. According to the error codes this should be due to Motor Overlad at normal operation speed.

It have started to happen quite often even when i'm doing low load cuts. If I just turn the spindle on and let it spin without any material I dont get the error. Seems like it also stops randomly without any error. Could it be noise on the control signal to the VFD? Could that also give an overload error?
