I've done it a few times with VFDs - it just decelerates the motor and then accelerates it the other way. EXCEPT if you have selected a "coast to stop" - then it tries to send motor in reverse while its still going fWDs, Depending how far it has slowed down the VFD trips and reports an error message.
