I've come across this several times and it's why I mentioned it above, the last time was with a 120kw inverter driving a steel beam straightening machine and due to the HSE requirement of stopping the machine within 10 seconds ( I think that time is right) it was best to allow the drive to ramp it down. If it had been left to coast down it would have taken ages to stop and a physical brake was not an option.
Using the on board output relay of the drive to detect 'motor stop' the power supply was then removed from the inverter as you say.
