Huanyang VFD problem

Hi all

My Huanyang VFD keeps randomly shutting down while in use ?
It’s always at different random times
Anyone had the same problem or have any solutions ?

When it’s stops the screen is flashing between the two pictures attached


Many thanks
Ash

AoA doesn't appear in any of the manuals I have.
The nearest is E.oA.A, which is for motor overload during acceleration.

How hard are you pushing the motor/spindle?
It may be worth setting the display to show current, and watching to see if you're pushing the spindle too hard.
