Weird bahavior between controller and 110 volt 2,2 kw Huanyang Spindle

Hi everyone,
Everything has been working flawlessly for months until a couple days back when I noticed the spindle stayed on when a program ended. I also noticed that the spindle rpm’s are not being displayed anymore. Connection trough the modbus appears to be ok, but once the spindle starts, it shows a timed out status. Only way to stop the spindle is by the stop button on the vfd. Once the spindle fully stops, the connection status go back to ok.
I havent been able to find anything similar in the forum. I’ll appreciate any help!
