It depends on the type of commands your VFD will accept, usually as a minimum, it is analogue 0-10v or bi-directional ±10vdc.
Unfortunately if you do not have a controller that outputs this type of signal you have to convert it, say from Mach type output, which is PWM to analogue.
There are converters for doing this.
Almost all VFD manufacturers will supply a 1HP 240 single phase in, three phase out VFD.
I am not sure of the makes available in your part of the world.
