I don't know about your yagi drives but I control a Danfoss drive with a cp1l plc using function blocks using Modbus easy master to do basically the same as you want.

with the Danfoss drives you have the ability to control the drives via digital input and or fieldbus with the option for logic for one to override the other so you could use a relay output to start the drive and then use Modbus for the control word for speed reference.
