You can throw all kinds of devices at your project to try and reduce noise, but the fact remains that VFDs can be very noisy devices.
I'd concentrate on properly grounding your system via a central star ground setup in your panel, and try and route the power, particularly the VFD motor lead wiring away from the lower voltage signal wiring. Start everything up and see what you have. Don't run your VFD motor leads wires in the same conduit, sealtite, or wireway in the panel with encoder cables or low voltage control wires. Buying input and output filters, may or may not be required. A dedicated AC transformer for the VFD will act as an input filter. I try and mount all of the power components at the top of the panel where the power enters the panel and put the computer and low voltages devices near the bottom. A lot of systems can get by without any filter devices at all if you are careful in how you wire the system.
