It's part of the smart-serial subsystem. Thats what we're told. And amazingly, the vfd is responsive to the click on either direction button, trundling along at about 100 rpms. I can stop it with virtually zero effort though so its useless at that speed. I don't have a lot of low speed boost dialed in, probably less than FLA. And its water cooled.
