Schindler did this on their Miconic VM product. The drive logic power supply (120VAC as well) also fed the drive fan below the drive SCR bank and on the top of the controller. Really had my head scratching as to the 'logic' on that design. There is also a fan airflow switch, and I would have thought using it would have been a more elegant method of pulling the car out of the service at the end of the run rather than during.
