Several programs support VFD controllers using the 0-10v drive
voltage found on nearly all any VFD unit but the GS2 series drives
from automationdirect.com also includes a handy RS232 serial
interface. The only software that I am sure supports the serial
connection to the GS2 drive at this time is cnczeus.
