I have a Mophorn 220V 4KW VFD and a Mophorn Spindle Motor 4KW.

Everything works as it should except when it's time to stop.

I played a little bit more with it this morning that it does the same thing with REV as it does with FWD.

It seems that Deceleration doesn't want to work. If I change the setting to 'stop by itself' it will slow down and stop after about 50 seconds. When I change it back to 'stop by deceleration' it will not stop and I have to unplug it. This is the same from external input (FWD or REV) and also from the VFD panel.

I bought the VFD over a year ago so I am at a loss of what to do.

Anyone have experience with this problem?
